RESUMEN

Men are particularly sensitive to penis size, especially those with a deformed or injured penis. This can lead to a strong desire for penis enlargement surgery. Given the ethical sensitivities of the penis, penile implants need to be developed with both efficacy and safety. In this study, a polyvinyl alcohol (PVA) patch for penile enlargement prepared via cyclic freeze‒thaw cycles and alkaline treatment. The PVA hydrogels treated with 5 M NaOH had the best mechanical properties and stability. A negative Poisson's ratio structure is incorporated into the design of the enlargement patch, which allows it to conform well to the deformation of the penis. In rabbit models, the enlarged patches can effectively enlarge the penis without degradation or fibrosis while maintaining long-term stability in vivo. This innovation not only provides a safe option for patients in need of penile enlargement but also promises to make a broader contribution to the field of dynamic tissue repair.

RESUMEN

Fournier's gangrene is a potentially life-threatening infectious disease involving the perineum and genitals. Aggressive surgical and medical management is often required, leaving the patient with large integumentary defects. The multiplicity of reconstructive options reported highlights the lack of consensus on the best covering option. Functional and aesthetic considerations are in play, and the literature is scarce on male black patients. We report here two cases of dark-skinned patients presenting with scrotal and penile integumentary defects that were respectively reconstructed with a superficial circumflex iliac artery propeller perforator flap and a split-thickness meshed skin graft and discuss the available literature on the topic.

RESUMEN

Background: Bacillus cereus (B. cereus) is a Gram-positive, rod-shaped, motile organism, found in the environment and may exist in contaminated food sources such as reheated rice, vegetables and may lead to gastrointestinal symptoms after ingestion including diarrhea, nausea, and vomiting due to enterotoxigenic and emetic toxins. Non-gastrointestinal infections of Bacillus cereus have been reported in the literature, which include cutaneous and non-cutaneous infections in immunocompetent and immunocompromised individuals. Case presentation: A 38-year-old man presented with a one-week history of penile swelling and redness that started after an episode of severe diarrhea and vomiting, which soiled his genital region few hours after vigorous intercourse with his wife. This has led to infection of the penile skin by an unusual organism: Bacillus (B.) cereus. The patient was treated using fucidic acid ointment applications for 2 weeks achieving complete recovery. Clinical discussion: The recovery of B. cereus from the penile infection in our patient reveals the first case of such an unusual infection, though this pathogen has been reported to cause a wide range of non-GI tract infections, which include bacteremia, meningitis, endocarditis, endophthalmitis, pneumonia, and soft tissue diseases. Virulence factors allow this organism to induce diarrhea in addition to having dermonecrotic, cytotoxic, hemolytic properties resulting in a wide range of dermatologic presentations. Conclusion: The authors report a unique case of penile skin infection caused by B. cereus, an unusual culprit for an uncommon presentation successfully treated with fucidic acid ointment. This is the first case in literature describing such an entity.

RESUMEN

INTRODUCTION: The use of hyaluronic acid as a nonsurgical treatment for various conditions within urology has been of great interest in recent literature. OBJECTIVES: In this study, we aimed to provide an updated review and analysis of the current state of hyaluronic acid use in urology, characterize its adverse effects, and briefly discuss future directions of research for hyaluronic acid in urology. METHODS: PubMed searches were run utilizing multiple terms, including "hyaluronic acid," "penile," "augmentation," "Peyronie disease," "premature ejaculation," and "cosmetic urology," among other related iterations. Relevant data extracted included International Index of Erectile Function score, intravaginal ejaculatory latency, glans circumference, penile girth, and plaque size. We also included studies which reported on complications of hyaluronic acid injections. Aggregated analysis was performed on studies with complete pre and post injection data at time closest to 6 months postinjection. RESULTS: A total of 33 studies met our inclusion criteria. Studies had marked heterogeneity in design, but most reported positive results. A total of 16 studies were included in our analysis. Intravaginal ejaculatory latency, penile girth, glans circumference, and International Index of Erectile Function were all increased on a fixed-effects model. Reduction in plaque size was not significant (P = .069). Complications were rare. CONCLUSION: Literature on hyaluronic acid for urologic issues demonstrates promising results; however, the quality of studies was variable. Our analysis of these studies largely corroborates these findings; however, the results are limited by the data available. Hyaluronic acid may be promising, but we highly implore standardization of study regimens in randomized controlled trials.

RESUMEN

Neoplasia has been reported to involve the majority of the urinary system of the horse, with tumors affecting the kidneys and bladder most comprehensively described. Primary tumors of the external genitalia are relatively common in the horse and are easily identified on clinical examination while primary tumors of the upper urogenital tract are uncommon. This article will highlight the common tumors, their clinical presentations, and discuss potential medical and surgical treatment options available. The less common neoplasms will be mentioned but not discussed in depth.

RESUMEN

Reproductive problems in cattle are frequent and have an important impact on production. In addition, inflammatory, traumatic and other diseases may be followed by the development of tumours, which are a cause of culling of breeding males. The main types of tumours diagnosed in the bull penis are fibropapilloma and squamous cell carcinoma. The aim of this study was to characterize a case of a tumour in the glans penis of a bull from a dairy farm in Santa Fe, Argentina. The neoplastic tissue was stained with haematoxylin and eosin and then analysed by immunohistochemistry to reveal its characteristic phenotype. Results showed positivity to vimentin, neuron specific enolase, proliferating cell nuclear antigen, S100 and glial fibrillary acidic protein. This suggested that the tumour was a neoplasm of neural origin, classified as neurofibrosarcoma, a peripheral nerve sheath tumour, here reported in the penis of a bull for the first time.

RESUMEN

A fixed drug eruption (FDE) is a common dermatological drug side effect but can go unnoticed. It is characterized by an oval-circular erythematous patch, sometimes with itching and burning pain localized in many parts of the body, such as the face, lips, torso, limbs, and anogenital area. Its diagnosis is generally clinical, but it can be mistaken for other dermatological diseases seen in primary care, like balanitis, genital herpes, and lichen planus. It can be a diagnostic challenge for primary care physicians when it is not considered. We present a 26-year-old man who developed an FDE in the penis with intense itching and burning pain during his labor hours after 15 minutes of consuming an oral dose of trimethoprim-sulfamethoxazole for a gastrointestinal infection. The patient was treated with topical corticosteroids twice per day and educated to avoid the use of the antibiotic again. In the next few days, the symptoms fully resolved, and he developed post-inflammatory hyperpigmentation in the area. The primary management of an FDE is immediate discontinuation of the offending drug and use of topical corticosteroids to prevent possible generalized reactions and recurrence of lesions. Therefore, the primary care physician should consider this condition in his or her diagnosis when new dermatologic lesions occur after exposure to a new drug.

RESUMEN

BACKGROUND: In recent years, there has been growing interest in the use of hyaluronic acid (HA) for the treatment of premature ejaculation (PE). The efficacy of this treatment is quite controversial. AIM: This study intended to evaluate the efficacy and safety of glans penis augmentation with HA gel for PE. METHODS: This systematic review includes randomized controlled trials (RCTs), primary clinical trials, prospective and retrospective studies, case series, and case reports. Searches in Embase, PubMed, Cochrane, Web of Knowledge, and ClinicalTrials.gov were performed blindly by 2 reviewers. OUTCOMES: Intravaginal ejaculation latency time (IELT), questionnaires about PE, glans circumference (millimeters), and adverse events. RESULTS: Thirteen studies were included in the evaluation: 4 RCTs, 8 prospective observational studies, and 1 restrospective study. The number of patients who received HA gel on the glans penis was 706. According to the results of 2 placebo-controlled RCTs, HA gel treatment significantly improved IELT at the end of the first month (mean difference [MD], 65.44 seconds). In the first month after the HA gel injection procedure, IELT increased vs before the procedure (MD, 176.18 [95% CI, 146.89-205.48]; P < .001, I2 = 83%). When the IELT values ​​were compared at 6 months after HA gel application, IELT improved vs before the procedure (MD, 143.93 [95% CI, 124.78-163.09]; P < .001, I2 = 82). The glans circumference expanded by approximately 1.5 cm after the procedure (MD, 14.82 mm [95% CI, 12.75-16.90]; P < .001, I2 = 65%). When the side effect profile of other studies was examined, side effects were observed in 91 patients after HA gel injection applied to 598 patients (15.22%). Among these side effects, the most common were pain (n = 46, 7.69%), bulla/nodule formation (n = 25, 4.18%), and ecchymosis (n = 20, 3.34%). CONCLUSION: While HA shows promise as a therapeutic option for PE, ongoing research is essential to elucidate its clinical utility, mechanisms of action, and comparative efficacy.

RESUMEN

BACKGROUND: Large language models including GPT-4 (OpenAI) have opened new avenues in health care and qualitative research. Traditional qualitative methods are time-consuming and require expertise to capture nuance. Although large language models have demonstrated enhanced contextual understanding and inferencing compared with traditional natural language processing, their performance in qualitative analysis versus that of humans remains unexplored. OBJECTIVE: We evaluated the effectiveness of GPT-4 versus human researchers in qualitative analysis of interviews with patients with adult-acquired buried penis (AABP). METHODS: Qualitative data were obtained from semistructured interviews with 20 patients with AABP. Human analysis involved a structured 3-stage process-initial observations, line-by-line coding, and consensus discussions to refine themes. In contrast, artificial intelligence (AI) analysis with GPT-4 underwent two phases: (1) a naïve phase, where GPT-4 outputs were independently evaluated by a blinded reviewer to identify themes and subthemes and (2) a comparison phase, where AI-generated themes were compared with human-identified themes to assess agreement. We used a general qualitative description approach. RESULTS: The study population (N=20) comprised predominantly White (17/20, 85%), married (12/20, 60%), heterosexual (19/20, 95%) men, with a mean age of 58.8 years and BMI of 41.1 kg/m2. Human qualitative analysis identified "urinary issues" in 95% (19/20) and GPT-4 in 75% (15/20) of interviews, with the subtheme "spray or stream" noted in 60% (12/20) and 35% (7/20), respectively. "Sexual issues" were prominent (19/20, 95% humans vs 16/20, 80% GPT-4), although humans identified a wider range of subthemes, including "pain with sex or masturbation" (7/20, 35%) and "difficulty with sex or masturbation" (4/20, 20%). Both analyses similarly highlighted "mental health issues" (11/20, 55%, both), although humans coded "depression" more frequently (10/20, 50% humans vs 4/20, 20% GPT-4). Humans frequently cited "issues using public restrooms" (12/20, 60%) as impacting social life, whereas GPT-4 emphasized "struggles with romantic relationships" (9/20, 45%). "Hygiene issues" were consistently recognized (14/20, 70% humans vs 13/20, 65% GPT-4). Humans uniquely identified "contributing factors" as a theme in all interviews. There was moderate agreement between human and GPT-4 coding (κ=0.401). Reliability assessments of GPT-4's analyses showed consistent coding for themes including "body image struggles," "chronic pain" (10/10, 100%), and "depression" (9/10, 90%). Other themes like "motivation for surgery" and "weight challenges" were reliably coded (8/10, 80%), while less frequent themes were variably identified across multiple iterations. CONCLUSIONS: Large language models including GPT-4 can effectively identify key themes in analyzing qualitative health care data, showing moderate agreement with human analysis. While human analysis provided a richer diversity of subthemes, the consistency of AI suggests its use as a complementary tool in qualitative research. With AI rapidly advancing, future studies should iterate analyses and circumvent token limitations by segmenting data, furthering the breadth and depth of large language model-driven qualitative analyses.

RESUMEN

OBJECTIVE: The purpose of this systematic review was to characterize methodologies reported in the literature to elicit and record pudendal somatosensory evoked potentials (SEPs) in human adults. METHODS: We conducted an electronic literature search in MEDLINE, Embase, CENTRAL, and CINAHL for studies that elicited pudendal SEPs via electrical stimulation and recorded responses though electroencephalography. From included studies, we extracted methodological details of how the SEPs were evoked and recorded. RESULTS: 132 studies were included in our review. The majority of participants were male (n = 6742/8526, 79%). Almost all studies stimulated the dorsal nerve of penis/clitoris. Stimulus parameters varied, with most standardizing stimulus intensity to 2-4x perceptual threshold, pulse duration to 0.1-0.2 ms, and frequency to 3 Hz. The number of stimuli recorded varied by clinical population. CONCLUSIONS: Our results demonstrate the inconsistencies of pudendal SEP methodology in the literature, with the majority (77%) of publications not reporting enough detail to reasonably replicate their protocol. Most research to date has been conducted in males, highlighting the paucity of female pelvic neurophysiology research. SIGNIFICANCE: We propose a Pudendal SEP Reporting Checklist for adequate reporting of pudendal SEP protocols. Optimal sex- and patient-specific methodologies to investigate all branches of the pudendal nerve need to be established.

RESUMEN

BACKGROUND: Penile skin zipper entrapment is an emergent medical condition in which the penile skin, scrotal skin, or foreskin gets caught within the teeth of a zipper or the slider itself. This can lead to complications such as urethral involvement, skin loss, or tissue necrosis. We propose a novel technique to aid in the release of entrapped skin utilizing wire cutters directed at the inferior portion of the zipper pull. OBJECTIVES: To describe a novel technique to free entrapped penile skin and compare its performance to the well-established median bar technique in a simulated setting. METHODS: A randomized cross-over design was used to compare techniques on successful release, time to release and tissue injury using an animal model of raw chicken skin entrapped in a zipper. Statistical significance was assessed at p < 0.05. RESULTS: Twenty-two participants were included. There was no statistically significant difference between the novel technique and the median bar technique regarding successful release (100% vs 95.5%, respectively), median time to release (29.1 vs 26.4 seconds, respectively), or frequency of tissue injury (22.7% vs 27.3%). CONCLUSION: Performance using our novel technique for removal of penile skin from a zipper is similar to the median bar release technique regarding. Our novel technique may be a valid treatment option for the release of entrapped penile skin in a zipper mechanism in the emergency department setting.

RESUMEN

INTRODUCTION: Although nerves and vessels of the penis play important role in erection, there are few studies on their development in human fetus. Therefore, the objective of the present study is to analyze, quantitatively, in the corpora cavernosa and corpus spongiosum, the development of the nerves and vessels in the fetal penis at different gestational ages. MATERIAL AND METHODS: Fifty-six fresh, macroscopically normal human fetuses aged from 13 to 36 weeks post-conception (WPC) were used. Gestational age was determined by the foot length criterion. Penises were immediately fixed in 10% formalin, and routinely processed for paraffin embedding, after which tissue sections from the mid-shaft were obtained. We used immunohistochemical staining to analyze the nerves and vessels in the corpus cavernous and in the corpus spongiosum. These elements were identified and quantified as percentage by using the Image-J software. RESULTS: The quantitative analysis showed that the percentage of nerves varied from 3.03% to 20.35% in the corpora cavernosa and from 1.89% to 23.88% in the corpus spongiosum. The linear regression analysis indicated that nerves growth (incidence) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.9421, p<0.0001) and (r2=0.9312, p<0.0001), respectively, during the whole fetal period studied. Also, the quantitative analysis showed that the percentage of vessels varies from 2.96% to 12.86% in the corpora cavernosa and from 3.62% to 14.85% in the corpus spongiosum. The linear regression analysis indicated that vessels growth (appearance) in the corpora cavernosa and corpus spongiosum correlated significantly and positively with fetal age (r2=0.8722, p<0.0001) and (r2=0.8218, p<0.0001), respectively, during the whole fetal period studied. In addition, the linear regression analysis demonstrated a more intense growth rate of nerves in the corpus spongiosum during the 2nd trimester of gestation, when compared with nerves in the corpora cavernosa. In addition, the linear regression analysis demonstrated a more intense growth rate of vessels in the corpus spongiosum when compared with the corpora cavernosa, during the whole fetal period studied. CONCLUSIONS: In the fetal period, the human penis undergoes major developmental changes, notably in the content and distribution of nerves and vessels. We found strong correlation between nerves and vessels growth (amount) with fetal age, both in the corpora cavernosa and corpus spongiosum. There is significant greater proportional number of nerves than vessels during the whole fetal period studied. Also, nerves and vessels grow in a more intense rate than that of the corpora cavernosa and corpus spongiosum areas.

RESUMEN

INTRODUCTION: Colorectal cancer is the second most common cause of death worldwide and may present as metastatic disease involving the liver, lungs and bones, and pelvic organs. Penile and scrotal metastasis may occur secondary to primary tumors originating from the genito-urinary tract. CASE PRESENTATION: We present a case of rectal adenocarcinoma metastatic to the penis and scrotum s/p chemotherapy and radiotherapy. His metastatic involvement was complicated by infections, necrosis and growth of maggots. Patient underwent wide excision and debridement of the metastatic deposits in the pubic, penile, scrotal and perineal region in addition to split-tissue skin graft from the right anterior thigh to cover the pubic region, the remainder of the penile shaft, and the scrotum. CLINICAL DISCUSSION: Peno-scrotal metastasis secondary to rectal adenocarcinoma is a rare condition. It may present as malignant priapism, hematuria, obstructive urinary symptoms occurring when there is urethral involvement. The mechanism of metastasis may be due to retrograde venous flow from the vesical, pudendal, hemorrhoidal plexuses, and the prostatic venous plexus draining the cavernosal veins of the penis. Additionally, lymphatic involvement and spread may play an important role in the spread of the disease. Treatment of such conditions relies on chemotherapy and radiotherapy and surgery for local control and symptomatic treatment. CONCLUSION: This article describes the rare occurrence of peno-scrotal metastasis of rectal adenocarcinoma and provides an overview on diagnosis, etiology, and management of the disease.

RESUMEN

PURPOSE: To answer the question of whether it is possible to achieve complete corporal covering of the urethral closure using incomplete penile disassembly in classic bladder exstrophy. We hypothesize that mobilization of the corpora under Buck's fascia, their dorsal translocation through the incisions in Buck's fascia and suturing corporal convex sides above the urethra would allow extend corporal covering of the urethra, reducing the risk of urethra-cutaneous fistula formation. MATERIALS AND METHODS: A prospective follow-up on all boys who underwent the modified Cantwell-Ransley primary penile reconstruction was conducted. Inclusion criteria comprised bladder exstrophy closure in our institution, ensuring a postoperative follow-up period of no less than 24 months. The key innovation of the technique lies in a deep dissection of the dependent corpora under Buck's fascia, followed by their dorsal relocation through extended dorsal incisions in Buck's fascia, and limited external corporal rotation 90 degrees only at the base of the penis. RESULTS: Between November 2019 and March 2022, 18 boys aged 11 to 35 months met the inclusion criteria and underwent the modified penile reconstruction. Surgical procedures and postoperative period did not include any major complications. Total corporal covering of the urethral sutures was achieved in 15 of 18 patients. No urethra-cutaneous fistulas were observed within 2 years of follow-up. All individuals demonstrated spontaneous erections, and the absence of dorsal curvature was documented. CONCLUSION: The modified technique of incomplete penile disassembly applied in a homogenous group of patients with classic bladder exstrophy allows penile shaft elongation, improved aesthetic outcomes, preserved erections, and eliminates dorsal curvature. The technique demonstrated feasibility and reliability while maintaining positive effects on tissue circulation. The absence of urethra-cutaneous fistulae is attributed to the complete corporal covering of the urethral sutures and supports the initial hypothesis.

RESUMEN

BACKGROUND: Penile trauma is associated with debilitating complications. Apart from its sparse literature, contextually relevant evidence on aetiology and standardized severity grading, and its stratification by legal age are needed. This study aimed to describe the frequency, aetiology and injury severity grade of patients, and explore the association of specific factors by legal age. SUBJECTS, MATERIALS AND METHODS: A single-centre retrospective cross-sectional study was conducted in our centre. Male patients with penile trauma managed by urologists were included. Data on age, year of presentation, aetiology, penile injury extent and co-existing genitourethral injuries were obtained. Descriptive and inferential statistics were undertaken using SPSS and MedCalc. Pvalue < 0.05 was considered significant. RESULTS: Forty-two patient records were analyzed. The median age and interquartile range for legal minors and legal adults were 9.5 (5.0-14.8) years and 31.0 (22.5-41.0) years, and they constituted 28.6% (n=12) and 71.4% (n=30) of the study population respectively. Penile trauma was isolated in 26.2% (n=11) of the total population.Its annual frequency was below the median volume between 2001 and 2008 but shifted to a rate above the average level between 2017 and 2021. The rate of conveyor belt-related aetiology and high-grade trauma was 41.7% and 75.0% in legal minors while it was 26.1% and 53.3% respectively in legal adults. CONCLUSIONS: Grade IV trauma was the most predominant while conveyor belt injury was the most common cause of the injury. Albeit limitations of statistical comparison, the rate of conveyor belt injury and high-grade trauma was numerically high in legal minors.

CONTEXTE: Les traumatismes du pénis sont associés à des complications débilitantes. Outre la rareté de la littérature, des preuves contextuel l ement per tinentes sur l ' étiol ogie et l a classification standardisée de la gravité, ainsi que leur stratification par âge légal, sont nécessaires. Cette étude visait à décrire la fréquence, l'étiologie et le degré de gravité des blessures des patients, et à explorer l'association de facteurs spécifiques par âge légal. SUJETS, MATÉRIELS ET MÉTHODES: Une étude rétrospective transversale monocentrique a été réalisée dans notre centre. Les patients masculins ayant subi un traumatisme pénien pris en charge par des urologues ont été inclus. Les données sur l'âge, l'année de présentation, l'étiologie, l'étendue de la blessure pénienne et les blessures génito-urétrales coexistantes ont été obtenues. Des statistiques descriptives et inférentielles ont été réalisées à l'aide de SPSS et MedCalc. Une valeur de p < 0,05 a été considérée comme significative. RÉSULTATS: Quarante-deux dossiers de patients ont été analysés. L'âge médian et l'intervalle interquartile pour les mineurs légaux et les adultes légaux étaient de 9,5 (5,0-14,8) ans et 31,0 (22,5-41,0) ans, représentant respectivement 28,6 % (n=12) et 71,4 % (n=30) de la population étudiée. Le traumatisme pénien était isolé chez 26,2 % (n=11) de la population totale. Sa fréquence annuelle était inférieure au volume médian entre 2001 et 2008, mais a dépassé le niveau moyen entre 2017 et 2021. Le taux d'étiologie liée aux tapis roulants et de traumatismes graves était de 41,7 % et 75,0 % chez les mineurs légaux, contre 26,1 % et 53,3 % respectivement chez les adultes légaux. CONCLUSIONS: Le traumatisme de grade IV était le plus prédominant, tandis que les blessures causées par les tapis roulants étaient la cause la plus courante de lésion. Bien que limitées par des comparaisons statistiques, les taux de blessures par tapis roulant et de traumatismes graves étaient numériquement élevés chez les mineurs légaux. MOTS-CLÉS: Facteurs d'âge, Étiologie, Score de gravité des blessures, Pénis.

RESUMEN

BACKGROUND: Extramammary Paget's disease (EMPD) is a rare intra-epidermal adenocarcinoma, and reconstruction of the penoscrotal region remains a clinical challenge. The superficial circumflex iliac artery perforator (SCIP) flap has been successfully used as a free flap, while its application as a propeller flap in the reconstruction of penoscrotal EMPD defect is rarely reported. The objective was to evaluate the safety and efficacy of the SCIP propeller flap in the reconstruction of penoscrotal defects in EMPD. METHODS: Between September 2010 and August 2022, consecutive patients diagnosed with penoscrotal EMPD were enrolled. All patients underwent penoscrotal EMPD excision and reconstruction with SCIP propeller flap combined with other flaps or skin grafts on individual defects. Demographic information, surgical parameters, postoperative complications, patient satisfaction, and recurrence rates were analyzed. RESULTS: Twenty-four patients (mean age, 73 ± 8.8 years; mean BMI, 23.98 ± 3.62 kg/m2) with 33 SCIP propeller flaps (mean size 120.1 cm2; range, 24-208 cm2) were included, and the mean defect size was 67.4 cm2 (range, 12-255 cm2). The mean operative duration was 385.4 ± 146.8 min. Fifteen patients received autologous full-thickness skin grafts, and four received other flaps simultaneously. All flaps survived without total or partial loss, and all donor sites achieved primary closure, though local hematoma (one case) and limited skin graft necrosis (two cases) were observed. All patients experienced complete wound healing and maintained penoscrotal morphology and function without recurrent lesions over a mean follow-up of 59 months. CONCLUSIONS: The SCIP propeller flap seems a safe and effective reconstructive method for penoscrotal EMPD. LEVEL OF EVIDENCE: IV.

RESUMEN

OBJECTIVES: To compare penile problems in circumcised relative to uncircumcised boys, and to determine which providers performing the circumcision have fewer post-circumcision problems. METHODS: CPT codes in the 2011-2020 MarketScan database were used to identify boys who had a circumcision. Uncircumcised control subjects of the same age, state of residence, and insurance type were selected. The primary outcome was a penile problem, defined as penis-specific infection, inflammation, and urethral stricture/stenosis, among others. The secondary outcomes were procedure-related complications limited to 28 days after circumcision, and whether post-circumcision problems varied by the clinician performing the procedure. ICD-9/10 diagnostic codes were used to identify these problems. RESULTS: We identified ∼850,000 cases and ∼850,000 matched controls. Overall, the rate of penile problems within the first five years of life was 1.7% in circumcised boys versus 0.5% in uncircumcised boys (p < 0.05). Multivariable regression models showed that the risk of penile problems was 2.9-fold higher among circumcised compared to uncircumcised males (95%CI [2.8-3], p < 0.001). Compared to males circumcised by pediatricians, those circumcised by surgeons had 2.1-fold higher penile problems in the year after circumcision (95% CI [2-2.3], p < 0.001). Procedure-related complications within 28 days of circumcision were infrequent (0.5%), with the most common being penile edema (0.2%). CONCLUSIONS: Penile problems are very infrequent in boys in the first five years of life. However, when they occur, they are 3x more likely to occur in circumcised boys relative to uncircumcised boys. Penile problems are more likely to occur in boys circumcised by surgeons. LEVELS OF EVIDENCE: Level II. TYPE OF STUDY: Prognosis study.

RESUMEN

Circumcision is commonly performed but anatomic variants occur and can affect outcomes if not addressed properly. The combination of concealed penis and penoscrotal webbing is fairly common and presents across a spectrum of severity. If not repaired, this can result in a buried penis that can cause penile adhesions, wound healing concerns, and make the penis appear shorter secondary to a retracted position. We present our technique that is reproducible and highly successful in addressing both of these concerns. The paraphimotic band approach is performed more commonly and is able to reliably correct webbing and concealment without an incision at the penoscrotal junction. When more severe defect is present, a Y shaped incision is made at the penoscrotal junction to mobilize skin flaps to correct the deficit. In our cohort of 885 patients, 736 were corrected using the paraphimotic band technique while 149 underwent a complex scrotoplasty. None of the patients required a secondary surgery for complications.

RESUMEN

Classically, cloacal exstrophy presents with omphalocele, bladder exstrophy, imperforate anus, and spinal defects. We report a rare variant of cloacal exstrophy in a 6-day-old male with an intact lower abdominal wall, normal penis, and urethra. Only two such cases have been reported in the literature.
