RESUMO

Cord lipomas are frequent findings in laparoscopic inguinal hernia surgeries in male patients. The symptoms of lipoma and the potential benefits of removing them are often overlooked because the focus is on the primary pathology of the hernia itself. Current recommendations are to reduce this fatty content, when present. When inguinal cord lipomas are left untreated in inguinal hernia surgery they can potentially cause symptoms and be detected in follow-up imaging exams. The objective of this study was to study incidence of cord lipomas in a cohort operated on by a single group specializing in abdominal wall surgery, as well as to analyze the possible relationship of this finding with the patient's symptoms, the characteristics of the operated hernia and postoperative outcome. This is a prospective study of male patients operated on for inguinal hernia laparoscopically or robotically in a single reference center. Of the total of 141 hernias, the distribution according to European Hernia Society classification showed that 45.4% were lateral, 19.1% medial and 35.5% mixed, highlighting a variety in the presentation of hernias. Analysis of the size of the hernias revealed that the majority (35.5%) were ≤ 1.5 cm. Inguinal cord lipoma was present in 64.5% of the samples, with no statistically significant association between the presence of the lipoma and an indirect hernia sac or obesity. The incidence of surgical site occurrences (SSO) was 9,2%, with seroma and hematoma. No recurrences were observed during follow-up, indicating a successful approach. There were no statistically significant relationships between SSO, the presence of lipoma and indirect hernial sac.

RESUMO

This study evaluated the possible association between the diurnal variations of climatic factors during the rainy (RS) or less rainy (LS) seasons on the testicular hemodynamics and thermoregulatory responses of hair sheep rams raised in a humid tropical climate. Santa Inês rams (n = 6) underwent evaluation of general and testicular physiological parameters (heart and respiratory rates, internal and scrotal temperatures, internal-scrotal temperature gradient, scrotal distention, and color Doppler ultrasound evaluation of the spermatic cords and spectral analyses of testicular arteries) over six consecutive weeks per season at three separate times daily (morning = 8:00 a.m., noon = 12:00 p.m., and afternoon = 5:00 p.m.) during the RS and LS. Climatic air temperature and relative humidity data were recorded, and the temperature and humidity index (THI) was calculated. Higher thermal challenge was observed in LS relative to RS (air temperature = 28.0 vs. 30.9 °C; relative humidity = 84.1 vs. 69.9%; THI = 80.0 vs. 82.5; P < 0.05). In both seasons, respiratory rate and internal temperature were normal, demonstrating the animals' adaptability. In RS, however, a higher scrotal temperature was recorded in relation to LS (35.0 vs. 34.7 °C; P < 0.05), with a gradual increase from morning to afternoon. Lower resistivity (0.40 vs. 0.64; P < 0.05) and pulsatility (0.55 vs. 1.14; P < 0.05) indices, and a higher rate of high-velocity blood flow of testicular arteries (71.1 vs. 60.6%; P < 0.05) were observed in RS compared to LS. The lowest correlations between testicular hemodynamic, physiological variables, and environmental parameters (P < 0.05) were observed in the morning. In conclusion, testicular thermoregulation and testicular hemodynamics were influenced by the climatic seasons and time of the day, being more efficient in the LS season and with less interference from environmental factors in the morning.

RESUMO

ABSTRACT Objective To report the effects of a tunica vagina flap on testicular compartment syndrome. Methods This single-arm clinical trial was conducted from September 2020 to October 2021. Consecutive patients with suspected testicular torsion within 24 hours of pain onset were included. Patients with past testicular torsion, bilateral torsion, or previous atrophy were excluded. The tunica vaginalis was opened, and the intratesticular pressure was measured before testicular retrieval from the scrotum and detorsion (P1), after detorsion (P2), and after transverse incision (P3). A tunica vaginalis flap was performed and a new intratesticular pressure was recorded (P4). The contralateral testicular pressure was recorded before fixation (Pc). The minimum follow-up period was 6 months. Results Fifteen patients were recruited from September 2020 to October 2021. Nine patients completed the follow-up. The median age (range) was 15 years (9-19). The mean P1, P2, P3, P4, and Pc (range) were 43, 60, 23, 20, and 14mmHg, respectively. The atrophy rate was 66.3% and the viability was 88.9%. No major complications were observed. Conclusion The modified tunica vaginalis flap in acute testicular torsion decreased intratesticular pressure. Furthermore, normal testicular pressure can improve testicular preservation. It can also decrease testicular pressure to normal levels and preserve the testicular parenchyma.

RESUMO

ABSTRACT Objective To evaluate the time interval and possible delay in transportation to referral units for the treatment of testicular torsion. Methods We retrospectively analyzed all cases of spermatic cord torsion surgically treated at a university hospital between January 2018 to December 2021. We evaluated the time intervals, including pain onset until the first presentation (D1), interhospital transference time (D2), pain onset until urological evaluation in a tertiary service (D3), urological evaluation until surgery (D4), and time from pain onset to surgical treatment (D5). We analyzed demographic and surgical data, orchiectomy rates, and time intervals (D1-D5). Torsions presented to the first medical presentation within 6h were considered early for testicular preservation. Results Of the 116 medical records evaluated, 87 had complete data for the time interval analysis (D1 to D5) and were considered the total sample. Thirty-three had D1 ≤6h, 53 had D1 ≤24h (includes patients in the D1 ≤6h subgroup), and 34 had D1 >24h. The median time intervals of the total samples and subgroups D1 ≤6h, D1 ≤24h, and D1 >24h were D1 = 16h 42min, 2h 43min, 4h 14min and 72h, D2 = 4h 41min, 3h 39min, 3h 44min and 9h 59min; D3 = 24h, 6h 40min, 7h and 96h; D4 = 2h 20min, 1h 43min, 1h 52min and 3h 44min; D5 = 24h 42min, 8h 03min, 9h 26min and 99h 10min, respectively. Orchiectomy rates of the total sample, subgroups D1 ≤6h, D1 ≤24h, and D1 >24h were 56.32%, 24.24% (p<0.01), 32.08% (p<0.01), and 91.18% (p<0.01), respectively. Conclusion Late arrival at the emergency department or a long interhospital transference time determined a large number of patients who underwent orchiectomy. Thus, public health measures and preventive strategies can be developed based on the data from this study aiming to reduce this avoidable outcome.

RESUMO

ABSTRACT Objective To assess testicular volumes and sexual maturation in patients with testicular torsion. Methods A retrospective analysis of consecutively treated patients with testicular torsion between 2016 and 2018. Age, pubic hair staging (Tanner), and by ultrasonography, volume of the unaffected testis (in cubic centimeters) were evaluated either immediately before surgery or at the first postoperative visit. Patients with previous testicular disease, such as cryptorchidism, or with no records of testicular volume were excluded. The analysis included descriptive statistics and Bayesian regression. Results We treated 149 patients during the study period, and 141 (94.6%, median age 17.3 years) met the inclusion criteria. Median testicular volume was 13.0cm3 (interquartile range of 10.5-15.2), with similar right and left volumes (12.9cm3versus 13.3cm3; p=0.94). Sixty-five (46.1%) patients were Tanner stage IV, 17 (12.1%) stage III, and 59 (41.8%) stage V. Conclusion In this study, we were able to estimate volumes of testicular torsion, which aggregated around late puberty values (13.0cm3 for the whole dataset, 12.2cm3 for patients <25 years), suggesting that testicular hypermobility, due to congenital anatomical abnormalities, remains quiescent until the organ reaches a critical volume, after which torsion becomes possible. These findings provide a tentative explanation for the disease's age distribution.

RESUMO

ABSTRACT Purpose: The aim of this paper is to propose a modified surgical technique for immediate intravaginal prosthesis implantation in patients undergoing orchiectomy due to testicular torsion, and to evaluate the wound healing process and patient's satisfaction. Material and methods: We prospectively analyzed 137 patients with testicular torsion admitted to our facility between April 2018 and May 2020. Twenty-five patients who underwent orchiectomy were included in this study. Fifteen had a testicular prosthesis implanted at the same time as orchiectomy using a modified intravaginal technique (summary figure) and 10 received implants 6 to 12 months after orchiectomy. Wound healing was evaluated at a minimum of four checkpoints (on days 15, 45, 90 and 180 after surgery). At the end of the study, a questionnaire was administered to measure patients' satisfaction rate. Student's t test was used for comparison of quantitative data between negative vs. positive cultures (p <0.05). The chi-square test was used to verify associations between categorical variables and immediate vs. late prosthesis implantation (p <0.05). Results: Patient's ages ranged from 13 to 23 years (mean 16.44 years). Overall time lapse from symptoms to orchiectomy ranged from 10 hours to 25 days (mean 7.92 days). Only one extrusion occurred and it happened in the late implant group. All wounds were healed in 72%, 88%, 95.8% and 100% of the cases on the 15th, 45th, 90th and 180th days after implant, respectively. At the end of the study, all patients stated they would recommend it to a friend or relative. The only patient that had prothesis extrusion asked to have it implanted again. Conclusion: There was no prosthesis extrusion using the modified intravaginal surgical technique for immediate testicular prosthesis implantation, which proved to be an easily performed and safe procedure that can avoid further reconstructive surgery in patients whose testicle was removed due to testicular torsion.

RESUMO

ABSTRACT Introduction: Spermatic vein thrombosis (SVT) is a very rare event with no specific epidemiological data. Its presentation is predominantly on the left, and in most cases, its cause is unknown. Its diagnosis is usually made by exclusion when studying acute scrotum pain. The following is the first case of SVT reported in Colombia and one of the few cases of right laterality in the world. Case presentation. A 21-year-old male patient consulted the emergency department of a tertiary care institution in Bogotá, Colombia, due to pain in the right inguinoscrotal region for a week that progressively increased in intensity and was accompanied by unquantified fever, without other associated symptoms. The patient reported only a medical history of a mild cranioencephalic trauma without sequelae at the age of 20 years. A testicular Doppler ultrasound was performed, revealing right spermatic cord thrombosis. He started antibiotic therapy, low molecular weight heparins and coumarin, which resulted in an adequate response and resolution of the condition. Conclusion: SVT poses a diagnostic challenge that requires a high clinical suspicion, which is achieved by having knowledge of this condition and establishing it as a differential diagnosis of acute scrotum pain. Once suspected, Doppler ultrasound becomes a useful tool for diagnosis because, in addition to being cost-efficient, it allows the initiation of a timely, safe and effective conservative treatment, thus avoiding unfavorable outcomes for the patient.

RESUMEN Introducción. La trombosis de la vena espermática (TVE) es una entidad muy poco frecuente de la cual no se tienen datos epidemiológicos específicos. Su presentación es de predominio izquierdo, en la mayoría de los casos su causa es desconocida y su diagnóstico suele realizarse por exclusión en el estudio del escroto agudo. A continuación, se presenta el primer caso documentado de TVE en Colombia y uno de los pocos de lateralidad derecha en el mundo. Presentación del caso. Hombre de 21 años quien consultó al servicio de urgencias de una institución de tercer nivel de atención de Bogotá, Colombia, por un cuadro clínico de una semana de evolución consistente en dolor en región inguinoescrotal derecha que aumentó progresivamente de intensidad y estuvo acompañado de un pico febril no cuantificado; el paciente indicó como único antecedente médico un trauma craneoencefálico leve sin secuelas a los 20 años. Se realizó estudio con ecografía Doppler testicular en donde se observó trombosis del cordón espermático derecho. Se inició manejó con antibioticoterapia, heparinas de bajo peso molecular y cumarínicos, con lo cual se obtuvo una adecuada respuesta y la resolución del cuadro. Conclusión. La TVE representa un reto diagnóstico, por lo que se requiere de una alta sospecha clínica, la cual se genera teniendo conocimiento de la entidad e incluyéndola en el diagnóstico diferencial del escroto agudo. La ecografía Doppler es una herramienta fundamental para diagnosticar TVE, además permite iniciar un tratamiento conservador oportuno, seguro y eficaz que evite desenlaces desfavorables para el paciente, lo que resulta ser costo-efectivo.

RESUMO

The aim of this study was to compare the biometric testicular characteristics, skin thickness and haemodynamics of the testicular artery of 12- and 24-month-old bulls using Doppler ultrasonography, the study was conducted using 48 indicus-taurus animals. The scrotal circumference (SC) and biometry characteristics of the bulls were measured to calculate the testicular volume. Doppler ultrasonography was used to obtain the haemodynamic values of the testicular artery. The skin thickness and volume were lower (p<.01) in the younger bulls (12 months:4.68 ± 0.68 mm; 168.76 ± 47.96 cm3 ) versus 24 months (5.05 ± 0.89; 499.73 ± 129.24 cm3 ) animals (p<.01). During diastole, mean velocity was lower in the 12 months (7.98 ± 3.83) than in the 24 months (11.37 ± 4.15) animals (p <.05). The 12-month-old animals had higher pulsatility and resistivity indices (0.49 ± 0.02; 0.51 ± 0.20) compared to the 24-month-old animals (0.32 ± 0.16; 0.40 ± 0.15) (p < .05). The final testicular end velocity was lower in animals with long/moderate-shaped (L/M) (7.31 ± 2.91) than in those moderate/oval-shaped (M/O) (11.48 ± 3.88) testicles (p < .05). Animals with L/M testes presented higher pulsatility values and resistivity indices (0.51 ± 0.05; 0.55 ± 0.04) compared to animals with M/O shape (0.29 ± 0.20; 0.36 ± 0.15). We showed that the blood flow of the supra testicular artery between the two evaluated ages differed, and that 24-month-old bulls presented better thermoregulation capacity. Animals with a long/moderate testicular format presented a greater vascular resistance, which was imposed on the blood flow due to the anatomical differences in the testicular artery, resulting in lower velocity, and indicating better heat dissipation in this format.

RESUMO

ABSTRACT Objective: To analyze the association between climate changes in the macroregions in the state of São Paulo and testicular torsion treated cases. Methods: The cases were selected in the Brazilian Public Health Data System Database from January 2008 to November 2016. All surgical procedure records were identified by the Hospital Admission Authorization document. Two codes were selected to process the search: testicular torsion (surgical cure code) and acute scrotum (exploratory scrototomy code). The macroregions were grouped in five areas linked to climate characteristics by International Köppen Climate Classification. Results: A total of 2,351 cases of testicular torsion were registered in the period. For the areas B, C and E (testicular torsion n=2,130) there were statistical differences found in association of testicular torsion cases and decreased temperature (p=0.019, p=0.001 and p=0.006, respectively), however, in analyses for the areas A and D statistical differences were not observed (p=0.066 and p=0.494). Conclusion: Decrease in temperature was associated with testicular torsion in three macroregions of São Paulo. The findings support the theory of cold weather like a trigger in occurrence of testicular torsion in a tropical climate region.

RESUMO Objetivo: Analisar a associação entre mudanças climáticas nas macrorregiões do estado de São Paulo e os casos tratados com torção testicular registrados. Métodos: Os casos foram selecionados no Banco de Dados do Sistema de Dados de Saúde Pública do Brasil de janeiro de 2008 a novembro de 2016. Todos os registros de procedimentos cirúrgicos foram identificados pelo documento de Autorização de Internação Hospitalar. Dois códigos foram selecionados para processar a busca: torção testicular (código de cura cirúrgica) e escroto agudo (código de escrototomia exploratória). As macrorregiões foram agrupadas em cinco áreas ligadas às características climáticas pela Classificação Internacional de Clima Köppen. Resultados: Foram registrados 2.351 casos de torção testicular no período. Para as áreas B, C e E (torção testicular n=2.130), foram encontradas diferenças estatísticas na associação dos casos de torção testicular e diminuição da temperatura (p=0,019, p=0,001 e p=0,006, respectivamente), mas nas análises das áreas A e D não foram observadas diferenças estatísticas (p=0,066 e p=0,494). Conclusão: A diminuição da temperatura foi associada à torção testicular em três macrorregiões de São Paulo. Os resultados apoiam a teoria do clima frio como um gatilho para ocorrência de torção testicular em uma região de clima tropical.

RESUMO

ABSTRACT Purpose To estimate statewide presentation delay, misdiagnosis rate, inter-hospital transfer times and testicular salvage for testicular torsion patients treated in our state's public health system. Patients and Methods Case series of consecutive testicular torsion patients treated in our state's public health system between 2012-2018. Predictors included presentation delay (time from symptoms to first medical assessment), facilitie's level-of-care (primary, secondary, tertiary), first diagnosis (torsion, epididymitis, other), Doppler-enhanced ultrasound request (Doppler-US) and inter-hospital transfer times, with surgical organ salvage as the main response. We used Bayesian regression to estimate the effect of first examining facilitie's level-of-care, first diagnosis, and Doppler-US on transfer time. Results 505 patients were included, most (298, 59%) with presentation delay >6 hours. Misdiagnosis at first examining facility raised transfer time from median 2.8 to 23.4 (epididymitis) and 37.9 hours (other) and lowered testicular salvage rates from 60.3% (torsion) to 10.7% (epididymitis) and 18.3% (other). Doppler-US had negligible effects on transfer time once controlling for misdiagnosis in the regression model. Although organ salvage in patients presenting before 6 hours at the tertiary facility was high (94.6%, and about 20% lower for those presenting at lower levels-of-care), the overall salvage rate was more modest (46%). Conclusion Our low overall testicular salvage rates originated from a large proportion of late presentations combined with long transfer times caused by frequent misdiagnoses. Our results indicate that efforts to improve salvage rates should aim at enhancing population-wide disease awareness and continuously updating physicians working at primary and secondary levels-of-care about scrotal emergencies.

RESUMO

Calcifying fibrous tumor of the tunica vaginalis is a rare fibrous proliferation, which can sometimes mimic a scrotal malignancy prompting surgical intervention. It has been recognized as a benign lesion, and no recurrence has been described after its resection. Its identification is essential to avoid overtreatment and unnecessary orchiectomy. We herein describe a rare case of calcifying fibrous tumor of the tunica vaginalis in a young patient and review the clinical features of inguinal and scrotal calcifying fibrous tumors to help clinical decisions and encourage a testis sparing surgery.

RESUMO

Purpose To evaluate the effect of remote ischemic conditioning associated to N-acetylcysteine (NAC) on testicular ischemiareperfusion (IR) injury in rats. Methods Twenty-five adult male Wistar rats were randomly distributed into five experimental groups (n=5), as follows: Sham, IR, Perconditioning (PER), NAC and PER+NAC. Two-hour ischemia was induced by rotating the left testis 720° to clockwise direction, followed by 4 hours of reperfusion. Perconditioning was performed by three I/R cycles of 10 min each on the left limb, 30 min before reperfusion. N-acetylcysteine (150 mgkg) was administered 30 min before reperfusion. Results Statistical differences were observed in MDA levels between I/R group with all groups (p 0.01), in addition there was statistical difference between PER and Sham, and PER+ NAC groups (p 0.05) in plasma. Conclusions The protective effect of perconditioning isolated in the reduction of lipid peroxidation related to oxidative stress was demonstrated. However, when Perconditioning was associated with NAC, there was no protective effect against testicular injury of ischemia and reperfusion.(AU)

RESUMO

Purpose To investigate the protective effect of Ganoderma lucidum on testicular torsion/detorsion (T/D)-induced ischemia-reperfusion (I/R) injury. Methods Thirty male Wistar albino rats were randomly categorized into 3 groups: Group 1: sham, Group 2 ( T/D): 2,5 hours of ischemia and 7 days of reperfusion, Group 3 (T/D+ G. lucidum ): 2,5 hours of ischemia and 7 days of reperfusion and 7 days of 20 mg/kg via gastric gavage G. lucidum polysaccharides per day. Biochemical assays of Malondialdehyde (MDA), superoxide dismutase (SOD), Catalase (CAT), Glutathione (GSH) levels , histopathology and expression levels of VEGF and Bcl-2 with immunohistochemical methods were examined in testicular tissue. Results G. lucidum treatment was found to have prevented the T/D-induced I/R injury by decreasing MDA levels of the testis. SOD, CAT and GSH activities were decreased in group 2, while they were increased in group 3 (p<0.001) and significant improvement in the tube diameter was observed in group 3. Bcl-2-positive germinal cells were lowered in group 3 compared to the group 2. VEGF expression showed an increase in group 2, whereas it decreased in group 3. Conclusion The antioxidant G. lucidum is thought to induce angiogenesis by reducing the apoptotic effect in testicular torsion-detorsion.(AU)

RESUMO

Introdução: Escroto agudo é uma síndrome clínica caracterizada por aumento do volume escrotal, associada à dor, sudorese, febre, náuseas e vômitos. Entre suas causas, destaca-se a torção de cordão espermático, que corresponde a rotação testicular sob seu eixo vascular, comprometendo a irrigação tecidual. Trata-se de uma emergência urológica cujo tratamento é cirúrgico. Objetivo: Relatar um caso e revisar a literatura acerca desta patologia. Materiais e Métodos: Revisão do prontuário e revisão da literatura. Resultados: Homem de 14 anos com dor intermitente no testículo esquerdo há duas semanas. A ultrassonografia diagnosticou torção testicular e do cordão espermático à esquerda. O paciente realizou orquiectomia tendo alta no dia seguinte. Conclusão: Os relatos de casos relacionados à torção de cordão espermático têm sua importância baseados na necessidade do aprendizado e no reconhecimento rápido dessa condição pelo profissional médico, visando o manejo adequado e de prontidão dos pacientes acometidos pela condição.

Introduction: Acute scrotum is a clinical syndrome characterized by increased scrotal volume, which is associated with pain, sweating, fever, nausea, and vomiting. Among its causes, the spermatic cord torsion is easy noticed and corresponds to the testicular rotation under its vascular axis, compromising tissue irrigation. It is a urological emergency, and its treatment is surgical. Objective: Report a case and review the literature about this disease. Materials and Methods: Medical record review and literature review. Case Results: A 14-year-old man with pain in his left testicle for two weeks underwent an ultrasound scan that detected testicular and spermatic cord torsion. A left orchiectomy was performed and the man was discharged the next day. Conclusion: Case reports related to twisting of the spermatic cord have its importance based on the need for learning and rapid recognition of this condition by the medical professional, aiming at an adequate and ready management of the patients affected by the condition.

RESUMO

Introducción: El sindrome escrotal agudo es una causa frecuente de consulta en la urgencia pediátrica y el diagnóstico de su etiología puede ser realmente un desafío para el pediatra y el cirujano. Existen múltiples etiologías posibles, siendo la torsión de cordón espermático la más importante, porque el retraso en su diagnóstico y tratamiento conlleva una alta incidencia de necrosis gonadal. Esta patología debe considerarse una emergencia quirúrgica. El objetivo de este artículo es conocer la situación de la torsión de cordón espermático en nuestro medio ya que existe un único estudio sobre esta patología realizado hace más de 30 años. Material y método: Se realizó un estudio observacional descriptivo y retrospectivo. Se identificaron todas las escrototomías realizadas con planteo clínico de síndrome escrotal agudo con la sospecha de una torsión de cordón espermático, en el período comprendido entre el 1.º de enero de 2015 y el 31 de diciembre de 2018. Se analizó la edad de los pacientes, patología diagnosticada en el intraoperatorio, lado afectado, sentido de la rotación y procedimiento realizado. Resultados: En el período comprendido entre el 1.º de enero de 2015 y el 31 de diciembre de 2018 se intervinieron quirúrgicamente 68 pacientes con diagnóstico de sindrome escrotal agudo. Del total, 49 pacientes (72 %) presentaron una torsión de cordón espermático, y a 16 (32,6 %) se les realizó orquiectomía. A todos se les realizó pexia testicular contralateral en el mismo acto quirúrgico. Conclusiones: En el período analizado fueron intervenidos 49 pacientes con torsión de cordón espermático. En 16 casos se realizó orquiectomía. Se identificó una leve predominancia del lado derecho, y el sentido de la rotación fue principalmente interno, si bien existe un importante subregistro de dicho dato en las descripciones operatorias. En el 72 % de los pacientes en quienes se decidió conservar la gónada, el cirujano describe una importante isquemia testicular, por lo que resulta fundamental realizar, para un futuro artículo, el seguimiento de estos pacientes para conocer su evolución.

Introduction: Acute scrotal syndrome is a frequent cause of consultation in the pediatric emergency and the diagnosis of its etiology can really be a challenge for the pediatrician and the surgeon. There are multiple possible etiologies, with torsion of the spermatic cord being the most important due to the high incidence of gonadal necrosis that the delay in diagnosis and treatment entails. This pathology should be considered a surgical emergency. The objective of this article is to know the situation of spermatic cord torsion in our environment since there is only one study done on this pathology more than 30 years ago. Material and method: A descriptive and retrospective observational study was carried out. All scrototomies performed with a clinical approach to acute scrotal syndrome were identified with the suspicion of spermatic cord torsion in the period between January 1, 2015 and December 31, 2018. The patients' age, pathology was analyzed. Diagnosed intraoperatively, affected side, direction of rotation and procedure performed. Results: In the period between January 1, 2015 and December 31, 2018, 68 patients were diagnosed with a diagnosis of acute scrotal syndrome. Of the total, 49 patients (72 %) had spermatic cord torsion, and 16 (32.6 %) had orchiectomy. All of them underwent contralateral testicular pexia in the same surgical act. Conclusions: In the analyzed period, 49 patients with spermatic cord torsion were operated. In 16 cases orchiectomy was performed. A slight predominance of the right side was identified, and the direction of rotation was mainly internal, although there is an important underreporting of this data in the operative descriptions. In 72 % of the patients in whom it was decided to preserve the gonad, the surgeon describes an important testicular ischemia, so it is essential for a future article to monitor these patients to know their evolution.

Existem múltiplas etiologias possíveis, sendo a torção do cordão espermático a mais importante devido à alta incidência de necrose gonadal que o atraso no diagnóstico e tratamento acarreta. Essa patologia deve ser considerada uma emergência cirúrgica. O objetivo deste artigo é conhecer a situação de torção do cordão espermático em nosso ambiente, uma vez que existe apenas um estudo sobre essa patologia há mais de 30 anos. Material e método: Foi realizado um estudo observacional descritivo e retrospectivo. Todas as escrototomias realizadas com abordagem clínica da síndrome escrotal aguda foram identificadas com suspeita de torção espermática no período de 1 de janeiro de 2015 a 31 de dezembro de 2018. A idade dos pacientes foi analisada. diagnosticado no intraoperatório, lado afetado, direção da rotação e procedimento realizado. Resultados: No período de 1 de janeiro de 2015 a 31 de dezembro de 2018, 68 pacientes foram diagnosticados com diagnóstico de síndrome escrotal aguda. Do total, 49 pacientes (72 %) apresentaram torção espermática e 16 (32,6 %) tiveram orquiectomia. Todos foram submetidos a pexia testicular contralateral no mesmo ato cirúrgico. Conclusões: No período analisado, foram operados 49 pacientes com torção espermática. Em 16 casos, foi realizada orquiectomia. Foi identificada uma ligeira predominância do lado direito, e o sentido de rotação era principalmente interno, embora exista uma importante subnotificação desses dados nas descrições operatórias. Em 72 % dos pacientes nos quais foi decidido preservar a gônada, o cirurgião descreve uma importante isquemia testicular, por isso é essencial que um artigo futuro monitore esses pacientes para conhecer sua evolução.

RESUMO

Abstract Purpose To evaluate the effect of remote ischemic conditioning associated to N-acetylcysteine (NAC) on testicular ischemia∕reperfusion (I∕R) injury in rats. Methods Twenty-five adult male Wistar rats were randomly distributed into five experimental groups (n=5), as follows: Sham, I∕R, Perconditioning (PER), NAC and PER+NAC. Two-hour ischemia was induced by rotating the left testis 720° to clockwise direction, followed by 4 hours of reperfusion. Perconditioning was performed by three I/R cycles of 10 min each on the left limb, 30 min before reperfusion. N-acetylcysteine (150 mg∕kg) was administered 30 min before reperfusion. Results Statistical differences were observed in MDA levels between I/R group with all groups (p<0.01), in addition there was statistical difference between PER and Sham, and PER+ NAC groups (p<0.05) in plasma. Conclusions The protective effect of perconditioning isolated in the reduction of lipid peroxidation related to oxidative stress was demonstrated. However, when Perconditioning was associated with NAC, there was no protective effect against testicular injury of ischemia and reperfusion.

RESUMO

Abstract Purpose To investigate the protective effect of Ganoderma lucidum on testicular torsion/detorsion (T/D)-induced ischemia-reperfusion (I/R) injury. Methods Thirty male Wistar albino rats were randomly categorized into 3 groups: Group 1: sham, Group 2 ( T/D): 2,5 hours of ischemia and 7 days of reperfusion, Group 3 (T/D+ G. lucidum ): 2,5 hours of ischemia and 7 days of reperfusion and 7 days of 20 mg/kg via gastric gavage G. lucidum polysaccharides per day. Biochemical assays of Malondialdehyde (MDA), superoxide dismutase (SOD), Catalase (CAT), Glutathione (GSH) levels , histopathology and expression levels of VEGF and Bcl-2 with immunohistochemical methods were examined in testicular tissue. Results G. lucidum treatment was found to have prevented the T/D-induced I/R injury by decreasing MDA levels of the testis. SOD, CAT and GSH activities were decreased in group 2, while they were increased in group 3 (p<0.001) and significant improvement in the tube diameter was observed in group 3. Bcl-2-positive germinal cells were lowered in group 3 compared to the group 2. VEGF expression showed an increase in group 2, whereas it decreased in group 3. Conclusion The antioxidant G. lucidum is thought to induce angiogenesis by reducing the apoptotic effect in testicular torsion-detorsion.

RESUMO

INTRODUCCIÓN: Los tumores paratesticulares representan del 7%-10% de las masas intraescrotales. Los sarcomas abarcan el 90% de las lesiones malignas del cordón espermático y de éstas, aproximadamente, el 3%-7% son liposarcomas. CASO CLÍNICO: Presentamos el caso de un varón de 45 años, que consultó en urgencias por una masa inguinoescrotal derecha no reductible, diagnosticándose de hernia inguinal incarcerada. Se realizó cirugía urgente evidenciando una gran tumoración de aspecto lipomatoso, dependiente de cordón espermático. Se realizó orquiectomía y hernioplastía inguinal. La anatomía patológica, reveló un liposarcoma bien diferenciado de cordón espermático. Posteriormente, se realizó estudio de extensión, sin afectación a distancia y no precisó tratamiento adyuvante. Actualmente, tras dos años de seguimiento no ha presentado recidiva. DISCUSIÓN: Sólo alrededor de 200 casos han sido comunicados previamente en la literatura y sólo 61 de éstos se presentaron simulando una hernia inguinal incarcerada. Debido a la baja incidencia de esta patología es difícil de conocer la historia natural y llegar a conclusiones sobre los resultados del tratamiento, el cual hasta el momento sigue siendo la orquiectomía radical, con escisión amplia de los tejidos locales. El papel de la radio y quimioterapia aun es controvertido. CONCLUSIONES: Los sarcomas del cordón espermático son neoplasias raras con alta tasa de recurrencia local. Su manejo inicial es quirúrgico. Se requiere de un alto índice de sospecha clínica para el diagnóstico ya que las implicaciones oncológicas varían en función del tratamiento que, en ocasiones, es llevado a cabo por cirujanos generales al simular una hernia inguinal.

INTRODUCTION: Paratesticular tumors represent 7%-10% of intraescrotal masses. Sarcomas account for 90% of malignant lesions of the spermatic cord and of these approximately 3%-7% are liposarcomas. CLINICAL CASE: This is the case of a 45 year old male who consulted in the emergency department for a non-reducible right inguino-scrotal mass and was diagnosed with an incarcerated inguinal hernia. Emergency surgery was performed which revealed a large lipomatous tumor, originating from the spermatic cord. Orchiectomy and hernioplasty were performed. Histopathology revealed a well-differentiated liposarcoma of the spermatic cord. Later extension study was conducted, without distant affectation, and did not require adjuvant treatment. Today, after two years of monitoring has been no recurrence. DISCUSSION: Only about 200 cases have been previously reported in the literature and only 61 of these were presented mimicking an incarcerated inguinal hernia. Due to the low incidence of this disease it is difficult to know the natural history and draw conclusions on the results of treatment, which so far remains the radical orchiectomy with wide local excision of the tissue. The role of radiotherapy and chemotherapy is still controversial
