RESUMEN

Objective: To present a series of cases with our initial experience and short-term outcomes of a modified vaginal mucosal flap urethroplasty. Methods: Patients diagnosed with urethral stricture and operated by the same operative technique between January 2012 and January 2018 were followed for at least 6 months. Uroflowmetry and clinical outcomes were evaluated. Results: Nineteen patients were included with an average age of 56.4 years, mean preoperative Qmax of 5.3 ml/s, and PVR of 101.4 mL. After 6 months of the procedure, the mean Qmax improved to 14.7 mL/s (p<0.05), PVR decreased to 47.3 mL (p<0.05), and 84.2% of all patients reported improvement in clinical self-reported symptoms. There was an improvement in symptoms such as voiding effort in 84.2% of patients, weak stream (89.5%), and recurrent urinary tract infection (85.7%). The success rate (absence of symptoms and normal Qmax with no significant PVR) of the procedure was 84.2%. Conclusion: The described technique was considered effective for the treatment of female urethra stricture, with a high clinical success rate and an objective improvement of Qmax and decrease in PVR after 6 months of the procedure.

RESUMEN

INTRODUCTION: Urethral stricture is a common, albeit complex, condition that predominantly affects men. The aim of this study was to translate, culturally adapt, and validate the Patient-Reported Outcome Measure questionnaire for patients undergoing urethroplasty (USS-PROM) into Brazilian Portuguese using validated psychometric criteria. MATERIALS AND METHODS: The process involved translating and culturally adapting the original USS-PROM into Brazilian Portuguese (USS-PROMbr), synthesizing, back-translating, cross-culturally adapting, and analyzing the pre-final version with experts from our committee. This pre-version was administered to 10 patients who had undergone urethroplasty by the Reconstructive Urology team at the Hospital de Clínicas de Porto Alegre for face validation, linguistic, and semantic adjustments, resulting in the final USS-PROMbr version. Subsequently, well-established psychometric criteria, including content validity, internal consistency, and test-retest reproducibility, were assessed after administering the questionnaire to a total of 56 patients, with 50 of them responding to the test and retest. RESULTS: Evaluation of the pre-final version identified 15 questions as clear, and only one question was considered somewhat unclear necessitating modifications based on patient suggestions and subsequent reassessment by the research team. Psychometric criteria demonstrated good content validity, with a content validity index exceeding 0.80 for all questions; good internal consistency, Cronbach's alpha of 0.77, ranging from 0.70 to 0.78 with the exclusion of any item, and item-total correlations ranging from 0.33 to 0.67. The test-retest intraclass correlation coefficient was 0.74 for the lower urinary tract symptoms construct (Q1-Q6). CONCLUSION: The USS-PROMbr demonstrated acceptable cross-cultural adaptation and psychometric properties, making it a valid and useful tool for evaluating patients undergoing urethroplasty.

RESUMEN

ABSTRACT Purpose: To evaluate the effect of the standardized laparoscopic simulation training program in pyeloplasty, following its implementation and during the COVID-19 pandemic. Material and Methods: A retrospective chart review was performed at Hospital de Clínicas de Porto Alegre, a tertiary referral center in south Brazil, in which 151 patients underwent laparoscopic pyeloplasty performed by residents between 2006-2021. They were divided into three groups: before and after adoption of a standardized laparoscopic simulation training program and during the COVID-19 pandemic. The main outcome was a combined negative outcome of conversion to open surgery, major postoperative complications (Clavien-Dindo III or higher) or unsuccessful procedure, defined as need for redo pyeloplasty. Results: There was a significant reduction in the combined negative outcome (21.1% vs 6.3%), surgical time (mean 200.0 min vs 177.4 min) and length of stay (median 5 days vs 3 days) after the adoption of simulation training program. These results were maintained during the COVID-19 pandemic (combined negative outcome of 6.3%, mean surgical time of 160.1 min and median length of stay of 3 days) despite a reduction in 55.4% of the surgical volume. Conclusion: A structured laparoscopic simulation program can improve outcomes of laparoscopic pyeloplasty during the learning curve.

RESUMEN

Background: Gender-affirming surgery is classically done using the penile inversion vaginoplasty technique, however in some patients it may not promote adequate depth. In patients whose vaginal conduits became short or stenotic, we propose to perform a secondary vaginoplasty using an abdominal free skin mesh graft. In this study, we present ours results of a series of cases using this technique. Methods: A retrospective review of patients undergoing secondary vaginoplasty with free skin mesh graft from 2000 to 2017 at our hospital was performed. Demographic data, surgical characteristics, complications, personal satisfaction and neovagina functionality (defined as the ability to have satisfactory sexual intercourse) were evaluated. Results: Of 186 patients who were submitted to primary vaginoplasty, 36 patients (19.3%) were then submitted to secondary vaginoplasty. This study sample included 35 patients. The average age of patients was 41.0 years (37.0 to 50.5) and the average time between gender affirmation surgery and secondary vaginoplasty was 6 months (4-24). Ten patients (28.6%) developed postoperative complication, the most frequent being: neovagina introitus stenosis (22.9%), rectal fistula (8.6%), tissue dehiscence (2.9%), and urethral fistula (2.9%). Subjective personal satisfaction and neovagina functionality of patients was reported by 77.1% of the sample. Conclusions: Our study demonstrates that secondary vaginoplasty surgery using a free skin mesh graft has good results and is a functional option with low complexity and low rate of serious complications.

RESUMEN

Purpose: Gender dysphoria (GD) is an incompatibility between biological sex and personal gender identity; individuals harbor an unalterable conviction that they were born in the wrong body, which causes personal suffering. In this context, surgery is imperative to achieve a successful gender transition and plays a key role in alleviating the associated psychological discomfort. In the current study, a retrospective cohort, we report the 20-years outcomes of the gender-affirming surgery performed at a single Brazilian university center, examining demographic data, intra and postoperative complications. During this period, 214 patients underwent penile inversion vaginoplasty. Results: Results demonstrate that the average age at the time of surgery was 32.2 years (range, 18-61 years); the average of operative time was 3.3 h (range 2-5 h); the average duration of hormone therapy before surgery was 12 years (range 1-39). The most commons minor postoperative complications were granulation tissue (20.5 percent) and introital stricture of the neovagina (15.4 percent) and the major complications included urethral meatus stenosis (20.5 percent) and hematoma/excessive bleeding (8.9 percent). A total of 36 patients (16.8 percent) underwent some form of reoperation. One hundred eighty-one (85 percent) patients in our series were able to have regular sexual intercourse, and no individual regretted having undergone GAS. Conclusions: Findings confirm that it is a safety procedure, with a low incidence of serious complications. Otherwise, in our series, there were a high level of functionality of the neovagina, as well as subjective personal satisfaction.

RESUMEN

INTRODUCTION: Burnout syndrome is a major cause of decreased life quality, mental health, and productivity for physicians. It is strongly related to work overload and has been a scarcely studied topic in pediatric urology. During the COVID-19 pandemic, authorities' recommendations have led to big changes in pediatric urology practice worldwide. This study aimed to evaluate the level of burnout in Ibero-American pediatric urologists (IPUs) during this pandemic. MATERIAL AND METHODS: A cross-sectional study was conducted by applying an electronic survey during the COVID-19 pandemic peak to members of the two major associations of pediatric urology in Ibero-America (the Ibero-American Society of Pediatric Urology [SIUP] and the Brazilian School of Pediatric Urology [BSPU]) to evaluate demographic, pre-pandemic, and pandemic data. Burnout levels were assessed using the Copenhagen Burnout Inventory (CBI) questionnaire. RESULTS: A response rate of 40% was obtained (182 out of 455 IPU respondents). Participants were from 14 different countries in Ibero-America and 75.4% were male. Data showed that during the pandemic there was a significant decrease in weekly workload, that is: > 40 h per week (h/w) (91.4%-44.6%, p < 0.001); and >6 h/w (94.9%-45.1%%, p < 0.001) in operating room time (ORT). Personal (Pe-BO), work-related (W-BO), and patient-related (Pa-BO) burnout levels among IPUs were 26.3%, 22.3%, and 7.4%, respectively (Summary table). An important difference by gender was seen, with women suffering more from the syndrome (odds ratio of 2.67 [95% confidence interval, 1.285.58; p = 0.013] for Pe-BO and OR of 3.26 [95% CI, 1.52-7.01; p = 0.004] for W-BO). CONCLUSION: A significant decrease in workload for IPU during the pandemic was observed, as well as a low level of burnout syndrome during this time. However, the predominance of burnout in women found in this study is notable.

RESUMEN

Congenital mid ureteric valve (MUV) stenosis is a very rare cause of ureteric obstruction and hydronephrosis (HN) in children. We describe how we manage laparoscopically one case of a patient with congenital MUV. We describe a 6-month-old boy born with antenatal left HN, with an anteroposterior diameter (APD) of 1,5 cm. Follow-up renal ultrasound at 3 months of age showed an increase in left kidney HN, approximately 2.5 cm below the PUJ associated with distal stenosis. Renal scintigraphy with DTPA showed an obstructive pattern. Urography scan showed an abrupt reduction in the caliber of the mid left ureter Based on a preoperative diagnosis of MUV stenosis, we performed a laparoscopic left ureteroplasty. Abrupt tapering of the left ureter at 3 cm from the PUJ was identified. Proximal ureter repair was performed before the resection of the narrowing segment. The two edges of the ureter were spatulated and continuous anastomosis was performed without tension. An antegrade JJ stent was inserted after the posterior part of the anastomosis was done. Patient made an uneventful recovery and was discharged on the first postoperative day. Laparoscopic ureteroplasty is a complex but feasible option to treat patients with congenital MUV stenosis.

RESUMEN

Strictures of the ureter may occur from iatrogenic injury or impacted kidney stones. Complications from ureteroscopy may result in ureteral stricture in 0,5-2% of patients. New techniques are being described in order to minimize the morbidity associated with classic approaches. This is a step-by-step video of this novel technique: a successful laparoscopic ureteroplasty with gonadal vein graft for a iatrogenic long ureteral stenosis. A 16 year old female patient, with multiple previous ureteroscopies for ureteral stones, presented with severe left lumbar pain. An abdominal CT and a pyelography were performed showing a 3 cm left mid-proximal ureteral stricture with proximal hydronephrosis. The stenotic area was identified and an anterior left ureteral incision was made. Gonadal vein was removed and prepared, being sutured in the anterior surface of the ureter. Patient was discharged in the second post operative (PO). JJ stent was removed after 1 month. A 3 month PO pyelography was performed, showing no fistula and resolution of the stricture. Twelve months after surgery, the patient was painless with symptom resolution. The use of gonadal vein as a graft for ureteral strictures is a new possible approach, although more cases are necessary to evaluate its results.

RESUMEN

AIMS: To evaluate the accuracy of dynamic ultrasonography (DUS), as a feasible alternative diagnostic method to identify detrusor overactivity (DO) in patients with neurogenic bladder. METHODS: We performed concurrent analysis of 81 pairs of urodynamic study (UDS) and DUS, in 63 patients with myelomeningocele (MMC), from June 2014 to February 2017. The assessment focused on bladder behavior during the filling phase, DO evaluation, DO with leakage, compliance, and maximum cystometric capacity (MCC). RESULTS: Patient age ranged from 3 months to 34 years (median, 84 months); 47.6% were male. Overall, 9.5% of patients had chronic kidney disease, 20.6% had recurrent urinary tract infection, 19.05% had vesicoureteral reflux, and 69.8% had constipation. Anticholinergic therapy was used by 41.3% of patients. DO was observed in 45.67% of patients and DO with leakage in 42.6%. Mean bladder compliance was 10.39 mL/cmH2 O and normal MCC was 56.79%. DUS had 91.89% sensitivity in identifying DO, 88.64% specificity, 87.18% positive predictive value, 92.86% negative predictive value, and 90.12% accuracy, with a kappa coefficient of 0.8 (P < 0.001). CONCLUSION: MMC follow-up is essential because urinary parameters can change during patient growth. The standard examination is invasive and has related complications, making noninvasive evaluation a desirable alternative, like DUS. Our data suggest that DO and MCC can be evaluated using DUS in patients with MMC. UDS should be performed in patients with abnormal findings on ultrasound evaluation or those with worsening of urinary tract function.

RESUMEN

OBJECTIVE: To present the results of technique of continent urinary diversion, described by Macedo, that allows the configuration of a tunnel with a flap of the ileal tube at the same segment created for the reservoir. METHODS: From January 2006 to November 2016, 29 patients were underwent a urinary diversion by Macedo's technique. Patients' demographics, hospitalization time, surgical time, follow up, continence rate, reservoir capacity, and postoperative complications were evaluated. RESULTS: Sixty-nine percent were male and the median age was 16.9 years. The main etiology was meningomyelocele (69.1%). The mean surgical time was 4.2 hours (standard deviation [SD] 0.9 range 2.9-6.3). The median length of hospital stay was 10 days (interquartile range: 11.3 range 5-51). The mean follow up was 3.3 years (SD 2.2 range 0.3-9.8). Procedure in the bladder neck was performed in 12 patients (41.3%). A continence rate of the catheterizable conduit was 82.8%.The reservoir capacity increased from 134.4 to 364.4 ml (P <.0001). The continence rate improved significantly (20 vs 74%, P <.0001). There was no change in glomerular filtration rates in the long term (143.1 vs 147, P = .45). Morbidity rate was 58% (25 complications in 17 patients), 72% occurred within the first 60 days and 60% were classified as Clavien-Dindo I or II. CONCLUSION: Except for publications from the original author, this is the first series described. The outcomes are similar, adding important data with respect to this technique. They show that the ileal reservoir is feasible, reproducible, and with good results.

RESUMEN

INTRODUCTION: The ideal vaginoplasty method should promote good cosmetic and functional results with low morbidity. We describe a new technique for congenital vaginal agenesis using a full-thickness perforated skin graft. MATERIALS AND METHODS: We report an 18 year old patient with vaginal agenesis (Morris syndrome) that undergone a modified version of McIndoe vaginoplasty. Patient is set in a low lithotomy position and lateral traction sutures are placed in labia and a 16Fr urethral catheter inserted. An inverted "V"-shaped incision is made in the mucosal plaque below the urethra. Blunt dissection in a cephalic posterior direction forms a space between the rectum and urethra. Special care is taken to avoid rectal tear during this maneuver. A full-thickness skin graft is removed from the lower abdomen measuring 12.0x6.0cm as an aesthetic abdominoplasty. The fat tissue is removed, remaining epidermis and dermis and the graft is perforated, allowing a great surface increase. After suturing over a mold, the graft is fixed in the created space. The donor site is closed with intradermal transversal suture. RESULTS: From January 2009 to August 2015, seven patients diagnosed with vaginal agenesis underwent this technique. There were no major complications or need for blood transfusions. At the six-month follow-up, all patients reported satisfactory sexual intercourse. There were no significant complications at donor site or neovagina that needed surgical intervention. CONCLUSION: Vaginal reconstruction using the perforated graft is viable with excellent functional results. Applying this modification, we yielded the good results of a classic McIndoe technique with lower donor site morbidity.

RESUMEN

OBJECTIVE: To present a novel technique in reconstructive urology for congenital vaginal agenesis using a full-thickness mesh skin graft and to evaluate the functional capacity for maintenance of satisfactory intercourse. METHODS: From January 2009 to August 2015, seven patients diagnosed with vaginal agenesis underwent vaginoplasty using a full-thickness mesh graft from lower abdominal skin. Herein, the authors describe the technique and initial results in adult patients. RESULTS: The mean hospital stay was 8 days. There were no major complications or need for blood transfusions. The most relevant postoperative result was the functionality of the neovagina and satisfactory donor site results. At 6-month follow-up, all patients reported satisfactory sexual intercourse. The average depth of the vagina was 11.3 cm. There were no significant complications at donor site or at neovagina that needed surgical intervention. CONCLUSION: We obtained positive functional results with minimal donor site morbidity by performing vaginal reconstruction using a full-thickness mesh skin graft.
