RESUMO

OBJECTIVE: To compare the outcomes of retrograde flexible ureteroscopy (fURS) with retroperitoneal laparoscopic ureterolithotomy (RLU) for large proximal ureteric stones. PATIENTS AND METHODS: A prospective randomised trial was conducted from January 2018 through December 2022 including patients with impacted proximal ureteric stones of 15-25 mm. Patients underwent fURS or RLU. Primary outcome was the stone-free rate. Demographic data, stone features, and complications rates were also compared between groups. RESULTS: A total of 64 patients were enrolled, 32 in each group. The mean impacted stone time was similar between groups, as well as stone size (17 mm) and stone density (>1000 Hounsfield Units). The ureteric stone-free rates between the two groups (93.7% in fURS vs 96.8% in RLU; odds ratio [OR] 0.72, 95% confidence interval [CI] -1.72 to 3.17; P = 0.554), and overall success rates, which take into account residual fragments in the kidney (84.3% in fURS vs 93.7% in RLU; OR 1.02, 95% CI -0.69 to 2.74; P = 0.23), were similar. Operative time was also not statistically significantly different between groups (median 80 vs 82 min; P = 0.101). There was no difference in hospital length of stay. Retropulsion rate was higher with fURS (65.6% vs 3.1%; p < 0.001). Residual hydronephrosis (34.3% each group) and complication rates did no differ according to treatment. CONCLUSION: Flexible URS and RLU are both highly efficient and present low morbidity for large impacted proximal ureteric stone treatment. RLU is not superior to fURS.

RESUMO

The renal arteries arise from the lateral side of the abdominal aorta at the L2 vertebral level, just below the origin of the superior mesenteric artery. Multiple aberrant renal arteries can pose difficulties in renal transplantation, interventional radiological and urological procedures, renal artery embolization, angioplasty, or vascular reconstruction for congenital and acquired lesions. We present a case of a left kidney supplied by the left renal artery along with superior and inferior polar arteries, arising from the aorta and inferior mesenteric artery respectively. The inferior mesenteric artery was crossed by the left ureter and inferior mesenteric vein. The superior polar artery gave rise to an inferior suprarenal artery making the variation important for clinicians and surgeons.

As artérias renais originam-se do lado lateral da aorta abdominal, no nível da vértebra L2, logo abaixo da origem da artéria mesentérica superior. A presença de múltiplas artérias renais aberrantes pode representar dificuldades para transplante renal, procedimentos radiológicos e urológicos intervencionistas, embolização da artéria renal, angioplastia e reconstrução vascular para lesões congênitas e adquiridas. Apresentamos um caso de rim esquerdo vascularizado pela artéria renal esquerda e pelas artérias polares superior e inferior, as quais se originavam da aorta e da artéria mesentérica inferior, respectivamente. A artéria mesentérica inferior era cruzada pelo ureter esquerdo e pela veia mesentérica inferior. A artéria polar superior dava origem à artéria suprarrenal inferior, o que torna essa variação importante para clínicos e cirurgiões.

RESUMO

INTRODUCTION: Fluorescence-guided surgery has emerged as a complement of traditional laparoscopic surgery with the advantage that is adaptable to existent platforms. The purpose of this article is to describe our technique for ureteral identification with indocyanine green (ICG) during laparoscopic colorectal surgery. MATERIALS AND SURGICAL TECHNIQUE: We report a case series of all patients who underwent laparoscopic colorectal surgery and ureteral injection of ICG in a private third level hospital. RESULTS: We performed 30 laparoscopic colorectal surgeries in which we used this technique to identify the ureters. Mean age was 52.6 ± 15.28 years; 16 (53.3%) were men. The indication for surgery was diverticulitis in 18 patients. Mean urological operative time was 22.4 minutes. There were no immediate or delayed adverse effects attributable to intra-ureteral ICG administration. DISCUSSION: Although ureteric iatrogenic injury is uncommon, when it does happen, it significantly increases the patient's morbidity. We consider this technique has the potential to make laparoscopic surgeries safer mostly in patients with cancer, diverticular disease or endometriosis who have extensive fibrosis, adhesions, and inflammation.

RESUMO

Blockage of ureter caused by kidney stone, accompanied by severe pain/infections, is a high incidence urinary tract disease that has received extensive attention. Currently, in clinics, a kidney stone with diameter less than ∼5 mm is considered capable of passing through ureter. However, this critical size (∼5 mm) is empirically based, lacking quantitative analysis. In this study, we proposed a stone-ureter interaction model to quantificationally estimate the critical size of kidney stone passing through ureter. We revealed that the critical size of kidney stone is related to ureter size, about 11%-22% larger than the inner diameter of ureter. Further, based upon the Winkler elastic foundation beam model, we developed a simplified stone-ureter interaction model to evaluate how this critical size is dependent upon the stiffness of ureter and the surface roughness of kidney stone. The proposed model may help urologists improve the accuracy of personalized diagnosis and treatment.

RESUMO

BACKGROUND: Obstructive uropathy is present in almost 50% of patients with advanced cervical cancer and is associated with worse outcomes. OBJECTIVE: To estimate the prognostic role of hydronephrosis and the impact of ureteral obstruction resolution in patients with locally advanced cervical cancer undergoing treatment. METHODS: A retrospective cohort study was conducted of patients with International Federation of Gynecology and Obstetrics 2018 stage IIIB to IVA treated in a tertiary oncologic referral center in Brazil between January 2009 and June 2018. Three different groups were evaluated: (I) without hydronephrosis, (II) with hydronephrosis and urinary diversion, and (III) with hydronephrosis but no urinary diversion. Kaplan-Meier curves and log-rank tests estimated overall survival and progression-free survival based on the presence of hydronephrosis and urinary diversion. Clinicopathological variables were evaluated using univariate and multivariate Cox proportional hazard regression model for overall survival and progression-free survival. RESULTS: A total of 151 patients were evaluated: group I - 62 (41.1%); II - 44 (29.1%), and III - 45 (29.8%). Stage, histological type or grade, tumor size, parametrial or lymph node involvement were not statistically different between groups. Group I had more favorable overall survival than groups II (p<0.003) and III (p<0.02); however, no difference was noted between groups II and III. Progression-free survival was similar between groups (log-rank test p=0.95). Univariate analysis revealed hydronephrosis (p=0.002) and concurrent chemoradiotherapy (p<0.001) as a prognostic factor for worse overall survival; while tumor size (p=0.023), pelvic lymphadenopathy (p=0.015), and histological type (p=0.03) were associated with worse progression-free survival. On multivariate analysis, hydronephrosis remained as an independently associated factor with worse overall survival (HR=2.06; 95% CI 1.12 to 3.79, p=0.02). CONCLUSION: Patients with locally advanced cervical cancer with hydronephrosis had lower overall survival even after controlling for potential confounding factors, but no difference in progression-free survival. Urinary diversion showed no impact on overall survival or progression-free survival.

RESUMO

Urolithiasis is a disease thatcan occur alone or together, obstruct the urinary flow, and even progress to the animal's death. Objective:The present study is to report the dissolution of calculus in the ureter in a kitten. Methodology: a feline, SRD, male, started at 3 months old with the signs of vomiting, constipation,and hematuria, presenting leukocytosis and increased serum urea. Two abdominal ultrasounds were performed 30 days apart and the third at 3 months. Results:Inthe first ultrasound there was hydronephrosis in the right kidney and dilation of the ureter and microlithiasis in the urinary bladder. The animalhad already been treated with antibiotic therapy and did not improve. Given these characteristics, Cantharis Vesicatoria30cH was administered, there was no more hematuria and when the drug was discontinued, the symptom returned. After 30 days of startinghomeopathic treatment, we repeated the ultrasound which showed 2 kidney stones, and a urinary bladder with cystitis associated with sandy lithiasis. BerberisVulgaris30cH was then administered for 15 days, after which both drugs were discontinued and theanimal remained asymptomatic. After 3 months the ultrasound was repeated which showed 2 kidney stones, Causticum6cH was inserted for 14 days to dissolvekidney stones, thus preventing the return of the initial symptoms. Conclusion:the treatment was beneficial for the patient, who was asymptomatic after the use of Causticum.Considering the natural history of the disease in cats and the high chance of recurrence of the disease, the recommendation was to monitor the organs through an annual ultrasound examination, in addition to encouraging water intake.

RESUMO

ABSTRACT Migration of foreign bodies into the urinary tract is a rare event. In certain instances, to unravel the way that objects arrived in the urinary tract is not easy. We report the case of an accidentally swallowed wooden toothpick that migrated and was found in the left ureterovesical junction, protruding into the bladder. Even though the computed tomography scan is widely employed to evaluate the urinary tract, this resource does not have a good sensitivity for detecting foreign bodies. Our report presents an insight into the best imaging approach if wooden toothpicks are suspected. In the present case, the endoscopic treatment was possible with an uneventful outcome and a complete resolution of symptoms.

RESUMO

ABSTRACT The improvement of surgical techniques in kidney transplantation aims to reduce the incidence of post-transplant complications, contributing to the reduction of hospital stay, related costs, morbidity and mortality, in addition to improving the quality of life of patients. The choice of the best technique is influenced by several factors and the most common technique for urinary tract reconstruction in transplants is performed with implantation of the ureter of the graft in the caudal position, with the anastomosis performed in the bladder. However, the kidney pole can be inverted and the graft ureter anastomosis can be performed directly on the recipient's ureter, facilitating venous and ureteral anastomoses and reducing urological complications.

RESUMO O aprimoramento das técnicas cirúrgicas no transplante renal tem o objetivo de reduzir a incidência de complicações pós-transplante, contribuindo com a redução do tempo de internamento hospitalar, os custos relacionados, a morbidade e a mortalidade, além de melhorar a qualidade de vida dos pacientes. A escolha da melhor técnica é influenciada por diversos fatores e a técnica mais comum de reconstrução do trato urinário nos transplantes é a realizada com implante do ureter do enxerto na posição caudal, com a anastomose feita na bexiga. No entanto, pode-se inverter o polo do rim, posicionando o polo inferior cranialmente e realizar a anastomose do ureter do enxerto diretamente no ureter do receptor, facilitando a anastomose ureteral e diminuindo as complicações urológicas.

RESUMO

The kidneys and ureters are retroperitoneal structures in the upper part of the paravertebral gutters, tilted against the structures on the sides of the lowest two thoracic and upper three lumbar vertebrae, so that their anterior and posterior surfaces face antero-laterally and postero-medially, respectively. Congenital anomalies of the urinary tract are often the underlying cause of renal pathologies; 40% of these pathological conditions are due to variations in location, shape, and size of the kidney(s), calyces, ureter, or bladder. This case report describes the presence of a unilateral non-rotated left kidney with vascular and ureter variations found during routine cadaveric dissection for medical graduates. Alterations in rotation of the kidney and its relation to structures at the hilum have great clinical significance when conducting surgical procedures like partial nephrectomy, nephron sparing surgery, and renal transplantation.

Os rins e o ureter são estruturas retroperitoneais localizadas na parte superior do sulco paravertebral, inclinados contra as estruturas laterais das duas vértebras torácicas inferiores e das três vértebras lombares superiores. Assim, as superfícies anteriores e posteriores estão nas porções anterolateral e posteromedial, respectivamente. As anomalias congênitas do trato urinário frequentemente são causas subjacentes de patologias renais, e 40% delas ocorrem devido a variações no local, formato e tamanho dos rins, cálices, ureter ou bexiga. Este relato de caso descreve a presença de rim esquerdo unilateral sem rotação com variações vasculares e de ureter encontradas durante uma dissecção de cadáver rotineira com graduandos de Medicina. As alterações na rotação do rim e a sua relação com as estruturas no hilo têm grande importância clínica durante procedimentos cirúrgicos como a nefrectomia parcial, a cirurgia poupadora de néfrons e o transplante renal.

RESUMO

ABSTRACT Introduction: Symptomatic duplex kidneys usually present with recurrent urinary tract infection due to ureteral obstruction (megaureter, ureterocele or ectopic ureter) and/or vesicoureteral reflux. Upper-pole nephrectomy is a widely accepted procedure to correct symptomatic duplex systems with poor functioning moieties, also known as upper or proximal approach. The distal ureteral stump syndrome (DUSS) can be a late complication of this approach. There is no consensus upon the length of ureteral dissection and the better approach to symptomatic disease in duplex systems, so we aim to identify if extended ureteral dissection can prevent DUSS in top-down approach. Materials and Methods: Forty-four consecutive patients with symptomatic duplex system were retrospectively classified into two groups: those with limited ureteral excision after heminephrectomy (HN) (group-1) and those with extended ureterectomy after HN (group-2). Patients were followed-up for at least 36 months regarding outcomes of distal ureteral stump. Results: Overall complication was 20%. A total of 8 patients required unplanned further surgery in Group-1 (30%) whereas only 1 patient required unplanned surgery in group 2 (6%) (p=0.07). Subgroup analysis showed that Group-1 presented more DUSS requiring surgery during follow-up than group-2 (p=0.04). Factors possibly affecting complications incidence (such as ureterocele or ectopic ureter) did not differ between groups (p=0.72 and p=0.78). Conclusion: Upper pole nephrectomy should be performed with extended distal ureteral dissection to prevent ureteral stump complications.

RESUMO

ABSTRACT Purpose: To describe our experience in the management of retained encrusted ureteral stents using a single session combined endourological approach. Materials and Methods: Patients with retained encrusted ureteral stents who had been submitted to a single session combined endourological approach from June 2010 to June 2018 were prospectively evaluated. Patients were divided according to the Forgotten-Encrusted-Calcified (FECal) classification. The stone burden, surgical intervention, number of interventions until stone free status, operation time, hospital stay, complications, stone analysis, and stone-free rate were compared between groups. ANOVA was used to compare numerical variables, and the Mann-Whitney or Chi-square test to compare categorical variables between groups. Results: We evaluated 50 patients with a mean follow-up of 2.9±1.4 years (mean±SD). The groups were comparable in terms of age, sex, laterality, BMI, comorbidities, ASA, reason for stent passage, and indwelling time. The stone burden was higher for grades IV and V (p=0.027). Percutaneous nephrolithotomy was the most common procedure (p=0.004) for grades IV and V. The number of procedures until the patients were stone-free was 1.92±1.40, and the hospital stay (4.2±2.5 days), complications (22%), and stone analysis (66% calcium oxalate) were similar between groups. The stone-free rate was lower in grades III to V (60%, 54.5%, and 50%). Conclusions: The endoscopic combined approach in the supine position is a safe and feasible technique that allows removal of retained and encrusted stents in a single procedure. The FECal classification seems to be useful for surgical planning.

RESUMO

Ureteral ectopy is a rare disorder in the small animals' clinic. It is characterized as a congenital anomaly, resulting from the ducts differentiation failure during embryogenesis. In this scenario, the ureters present themselves outside the anatomical site, being inserted into the uterus, urethra, urinary vesicle neck, or vagina. The clinical signs are urinary incontinence and perivulvar dermatitis. Surgery is the accepted treatment to correct the anomaly. The surgical procedure is based on relocating the ectopic ureter and treating associated modifications. This report describes a case of intramural bilateral ureteral ectopy, corrected surgically through the neoureterocystostomy technique, making it possible to control the animal's urinary incontinence.(AU)

A ectopia ureteral é uma afecção de incidência rara na clínica de pequenos animais, sendo caracterizada como anomalia congênita resultante de falha na diferenciação dos ductos durante a embriogênese. Neste cenário, os ureteres se apresentam fora do seu local anatômico, sendo inseridos no útero, no colo da vesícula urinária, na uretra ou na vagina. Os sinais clínicos comumente apresentados são a incontinência urinária bem como a dermatite perivulvar. O tratamento de eleição para correção da anomalia é o procedimento cirúrgico, no qual a técnica de escolha é baseada na relocação do ureter ectópico e tratamento das alterações associadas. Neste contexto, o presente relato descreve um caso de ectopia ureteral bilateral intramural, corrigido cirurgicamente por meio da técnica neoureterocistostomia, o que possibilitou controle da incontinência urinária do paciente.(AU)

RESUMO

A herniação do ureter é uma condição médica extremamente rara e geralmente ocorre após transplantes ou ptose renal. A maioria dos casos relatados são identificados no momento da exploração cirúrgica para correção de hérnia inguinal, ou posteriormente como resultado de uma lesão operatória. Os pacientes comumente são assintomáticos até o agravamento do quadro, a idade média afetada é entre a quinta e sexta década de vida. O relato de caso destaca a importância de um diagnóstico precoce de um fenômeno incomum para evitar possíveis complicações. A herniação do ureter é uma causa importante de complicações no enxerto após transplantes renais, os sintomas dependem do grau de obstrução ureteral, localização e da presença de agravos. O procedimento de correção geralmente consiste em hernioplastia, inserção de stent e, em alguns casos, até mesmo ressecção do ureter e reanamastose. Devido ao risco de uropatia obstrutiva o tratamento deve ser realizado com cautela

Ureter herniation is an extremely rare medical condition and usually occurs after transplants or renal ptosis. Most of the reported cases are identified at the time of surgical exploration to correct an inguinal hernia, or later as a result of an operative injury. Patients are usually asymptomatic until the condition worsens, the average age affected is between the fifth and sixth decade of life. The case report highlights the importance of an early diagnosis of an unusual phenomenon to avoid possible complications. Herniation of the ureter is an important cause of graft complications after kidney transplants, the symptoms depend on the degree of ureteral obstruction, location, and the presence of injuries. The correction procedure usually consists of hernioplasty, stent insertion, and, in some cases, even resection of the ureter and resuscitation. Due to the risk of obstructive uropathy, treatment should be carried out with caution
