RESUMO

INTRODUCTION: Surgical removal of the tumor is a key step in the management of nephroblastoma. Less invasive surgical approaches such as robot-assisted radical nephrectomy (RARN) has gained momentum over the past few years. This video presents a comprehensive step-by-step video for two cases: one uncomplicated left RARN and one more challenging right RARN. MATERIALS & METHODS: Following the UMBRELLA/SIOP protocol, both patients received neoadjuvant chemotherapy. Under general anesthesia, in a lateral decubitus position, four robotic and one assistant port are placed. After mobilization of the colon, the ureter and gonadal vessels are subsequently identified. The renal hilum is dissected, and the renal artery and vein are divided. The kidney is dissected with sparing of the adrenal gland. The ureter and gonadal vessels are divided, and the specimen is removed through a Pfannenstiel incision. Lymph node sampling is performed. RESULTS: Patients were 4 and 5 years old. The total surgical time was 95 and 200 min, with an estimated blood loss of 5 and 10 cc. The hospital stay was limited to 3 and 4 days. Both pathological reports confirmed the diagnosis of nephroblastoma, with tumour-free resection margins. No complications were observed 2 months postoperatively. CONCLUSION: RARN is feasible in children.

RESUMO

INTRODUCTION: Pyeloplasty (open or Robot-assisted) is the gold standard of a symptomatic UPJ stenosis. Sometimes anatomic variants make the procedure challenging. This video describes a step-by-step approach in three settings: a crossing blood vessel and two different presentations of incomplete duplicated system. MATERIALS AND METHODS: Under general anesthesia, patient positioned in lateral decubitus, three trocars are placed. After mobilization of the colon, the Gerota's fascia is opened, and the renal pelvis is dissected off the surrounding structures. Ureter and obstructed pyelum were subsequently identified, mobilized, and hinged on a traction stitch. The pyelum and ureter are divided and spatulated according to the Anderson-Hynes technique; anastomosis is achieved. In variants, the drainage is one of the challenging steps, needing custom-made drainage of both moieties. Correct positioning of the drainage is confirmed with reflux of methylene blue from the bladder. RESULTS: JJ stent was removed 6 weeks postoperatively in surgical day-clinic, additional drainage was removed 1 week after surgery in the outpatient clinic. All three children remain asymptomatic with over a year of follow-up. CONCLUSION: A step-by-step plan for pyeloplasty in case of anatomic variants is presented with a video demonstrating a robot-assisted approach in duplicated systems. Moiety drainage can be challenging.

RESUMO

INTRODUCTION: Scarce data is available in literature about the upper urinary tract outcomes of patients with Exstrophy-Epispadias Complex (EEC). After bladder closure during childhood, EEC bladders can become hostile to the upper tracts after bladder by exposing them to high pressures, leading to hydronephrosis (HN) and kidney damage. Similarly, vesicoureteral reflux (VUR) may be present and increase the likelihood for pyelonephritis. OBJECTIVE: We sought to assess long-term upper urinary tract outcomes by evaluating renal function, HN and VUR; and to assess if upper urinary tract outcomes are associated with continence status. STUDY DESIGN: A retrospective review of EEC patients having ≥1 surger(y) (ies) at our institution from 1990 until 2019 was performed. Renal function was assessed by evaluating last available estimated glomerular filtration rate (eGFR) and creatinine values. HN was assessed on ultrasound and classified according to the SFU-classification. Patients with recurrent febrile urinary tract infections (UTI) or pyelonephritis underwent a voiding-cystourethrogram (VCUG) assessing VUR, graded following the 'International system of radiographic grading of VUR'. Descriptive and comparative statistical analysis were performed to assess if upper tract outcomes are associated with continence status. RESULTS: Forty-eight patients (75% male) had a median (IQR) follow-up of 18 (10-21) years. The table shows upper tract outcomes for the entire group and stratified by continence status. The median creatinine was 0.6 (0.2-0.9) mg/dL and median eGFR was 108 (72-160) mL/min/1.73 m [2]. In two patients (4.2%), HN (SFU-grade 2) was detected. Thirty-six patients (75%) underwent VCUG, revealing high-grade VUR (stage IV-V) in 8 patients (17%) and low-grade VUR (stage I-III) in 7 patients (15%). Continence was associated with a higher need for VCUG (p = 0.02) and a higher presence of VUR (p = 0.03). DISCUSSION: Renal function in EEC patients and non-EEC patients is comparable when age matched. Only 6% had low-grade HN which was asymptomatic. 17% had high-grade VUR, which is little compared to literature (40-70%). However, results in literature are described in patients with a 'one-stage' bladder closure, whereas some of our patients had a 'two-stage' procedure. A one-stage procedure creates higher bladder pressures resulting in higher VUR-rates. Statistical analysis has showed that continence is associated with a higher prevalence of recurrent febrile UTI's or pyelonephritis and of VUR. CONCLUSIONS: No statistically differences were found between continent and incontinent patients concerning creatinine and eGFR value (p = 0.52 and p = 0.29), nor in the prevalence of hydronephrosis (p = 0.36). However, results of this study suggest that continent patients may portend a higher risk of upper tract deterioration with recurrent febrile UTI's and pyelonephritis due to VUR. Close monitoring of the upper tract status is therefore as important as focus on continence. Large-scale prospective studies defining renal function as well as pyelonephritis rates are needed to optimize the management of the upper tracts in EEC patients.

RESUMO

PURPOSE: We assessed the long-term surgical, functional urinary and sexual outcomes of adolescent and young adult men who underwent childhood hypospadias repair. MATERIALS AND METHODS: Men born with nonsyndromic hypospadias and healthy male controls aged 16-21 years old were recruited, and their surgical, urinary, sexual functional and aesthetic outcomes assessed. Good outcome was defined as a patent and orthotopic meatus without fistulas, and straight erections (<30 degree curvature) without erectile or ejaculatory problems. Statistics included regression analyses, chi-square/Fisher exact tests and Student's t/Mann-Whitney U and Kruskal-Wallis tests. RESULTS: A total of 193 patients and 50 controls participated 16.4 years (range 8.2-21.2) after initial repair. At least 1 reintervention was performed in 39.2%. The highest reintervention rate was found in those younger than 12 months at initial repair, even when excluding proximal hypospadias cases. A disturbed urinary and/or suboptimal sexual functional outcome was seen in 52.9% of cases. Suboptimal voiding was found in 22.1%, although few had relevant residual urine. More reinterventions and proximal hypospadias cases were associated with suboptimal urinary outcome, and the latter also with impaired sexual function. Poor inter-observer agreements were found between physician and patient genital appraisal. CONCLUSIONS: In 52.9% of cases, at least 1 concern was identified that required long-term followup. Hypospadias repair below 12 months was associated with more reinterventions. Adopting a restrictive attitude toward aesthetic refinement, unless on the patient's own request, could improve urinary outcomes.

RESUMO

Gaining an esthetical skin coverage can be challenging in some hypospadias repair cases, especially in those with significant ventral skin paucity. A local institutional technique used to correct ventral skin paucity in hypospadias is described. It consists of a redistribution of the abundant dorsal skin and its hooded prepuce to the ventral side of the penis where skin shortage is observed. Reallocation of the skin is performed by buttonholing the dorsal skin to the ventral side. This versatile technique can be adapted to most penile surgeries where some ventral skin paucity is observed.

RESUMO

Exstrophy-epispadias complex (EEC) is a spectrum of genitourinary malformations that ranges in severity and affects external genitalia and the lower urinary tract. The aim of this study was to determine the long-term sexual outcomes of patients with EEC. Sexual outcomes were hypothesized to be related to those of urinary ones. A retrospective database including all patients with EEC who had surgery at a tertiary referral institution from 1990 to 2019 was created. Data based on patient's charts were collected: demographics, surgeries, sexual outcomes, urinary outcomes. Fifty-eight patients with EEC had surgery at tertiary referral institution and entered our database. For this analysis of sexual outcomes, a sub-set of the whole population was selected: patients being 14 years old and older, having at least one surgery at our institution and having at least 12 months of follow-up. Applying this selection criteria to our database resulted in a series of 29 patients. High rates of sexual activity were observed in pubertal and post-pubertal men (96%) and women (75%). Seventy-nine percent of men and 67% of women reported sexual satisfaction; 63% of men reported normal ejaculation. To achieve these rates, 96% of men required surgery (84% penoplasty, 52% phalloplasty), and 25% of women required introitoplasty. Fertility was achieved in 67% of men and 100% of women. Assisted reproductive technology was needed in one man. Continence rates were high (diurnal continence in 83% and nocturnal continence in 93%). However, 76% required multiple continence procedures. Men and women with EEC can have good long-term sexual and urinary outcomes, but this may require multiple surgeries. Good sexual outcomes seem to be related to good urinary and continence outcome.

RESUMO

BACKGROUND: The psychosexual outcome in adolescents and young adults (AYA) men born with hypospadias is precarious. However, the factors responsible for impaired outcome in some AYA men have been understudied. AIM: To explore the outcome after hypospadias repair in childhood of AYA men aged 16-21 years and examine their opinion and their parents' opinion about this type of surgery. METHODS: Cross-sectional assessment of 193 AYA men born with hypospadias and 50 male controls was performed. Questionnaires such as the Decision Regret Scale, Pediatric Penile Perception Score, Sexual Quality of Life-Male, International Index of Erectile Function, and a custom-made questionnaire were used. The Decision Regret Scale and a custom-made questionnaire were also completed by the participants' parents. Physical examination including Hypospadias Objective Penile Evaluation and measuring stretched penile length was performed. OUTCOMES: This study reports the psychosexual functioning (ie, social, relational, and sexual), erectile and sexual function after childhood hypospadias repair, using ad hoc measures. In addition, the opinion about hypospadias repair of patients and their parents is represented. RESULTS: The number of surgeries and satisfaction regarding penile appearance were the most important factors associated with the opinion on hypospadias repair and the psychosexual outcome. Most AYA men were more satisfied with their penile appearance than the physician. 80% of men were satisfied with having had a childhood hypospadias repair, even though they had not been able to consent to surgery themselves. Erectile and ejaculation problems were mild and seen in approximately 10% of the population. CLINICAL IMPLICATIONS: Based on our data, deferring hypospadias repair until the patient can decide himself is not warranted. However, physicians who accept a suboptimal esthetic outcome and withdraw from repeated surgery may contribute importantly to the patient's well-being, especially in proximal forms of hypospadias. STRENGTHS & LIMITATIONS: This is one of the rare studies addressing the AYA's psychosexual outcome after childhood hypospadias repair. Strengths include the combination of clinical and psychosexual data from a very large cohort of men and their parents to provide a more holistic view. By entering this study, participants might have a different comfort level regarding their sexuality or have a different body image than the overall population of young men. CONCLUSION: Uncomplicated hypospadias surgery results in equal psychosexual outcome as controls and in high satisfaction rates; multiple surgeries are a risk factor for poorer outcomes. 80% of men are satisfied with childhood hypospadias repair.

RESUMO

BACKGROUND AND OBJECTIVE: Differences of sexual development (DSD) affect the development of internal reproductive organs and external genitalia. Ectopic kidney is a rare and challenging pathology causing amongst others incontinence and recurrent urinary tract infections. Those pathologies may in certain cases be an indication for surgery. This manuscript aims to evaluate the role of robot-assisted laparoscopy in the surgical treatment of patients with ectopic kidneys or DSD. MATERIALS AND METHODS: A prospective database is maintained in a tertiary referral center with all robotic surgeries performed in children. From this database, a prospective series of robot-assisted resection of embryologic remnants located in the pelvis was extracted: resection of a prostatic utricle cyst, removal of ectopic non-functional kidneys, and resection of a hemi-uterus. RESULTS: From an initial database including 72 patients, six patients met the inclusion criteria. Three male patients presenting with utricle cysts, two young girls presenting with ectopic kidneys, and one young boy with pelvic embryological remnants of the uterus, were further evaluated. CONCLUSION: Surgical treatment of patients with DSD is safe, feasible, and a good indication for robot-assisted laparoscopic surgery, as both deep dissection and reconstruction in a limited surgical field are requested.

RESUMO

INTRODUCTION: Kidney transplantation (KT) is the gold-standard treatment for end-stage renal disease (ESRD) in children. Robot-assisted kidney transplantation (RAKT) in adults is becoming increasingly common with potentially improved morbidity compared with open KT. The study objective was to evaluate feasibility and outcomes of RAKT in children. PATIENTS & METHODS: An 8-years-old boy with ESRD received a kidney transplant from his mother. Simultaneously in two operation theatres, the boy underwent single-port (GelPOINT®) right laparoscopic nephro-ureterectomy (LNU), and his mother underwent robot-assisted left donor nephrectomy (RADN).Two full surgical teams were operating at the same time. Subsequently, the boy underwent RAKT, introducing the graft through the GelPOINT®. RESULTS: Total operative time for LNU, RADN, and RAKT was 180, 140, and 195 min, respectively, with warm, cold, and rewarming ischemia times 1.5, 200, and 47 min, respectively. Blood loss was 300, 20, and 50 cc, respectively. No intraoperative complications were noted. Convalescence of both donor and recipient was uneventful, with good kidney function at 1-year follow-up. CONCLUSION: RAKT in children is technically feasible and safe, resulting in excellent graft function. Concomitant nephrectomy can be done laparoscopically through the single-site GelPOINT®. An experienced RAKT team with the full support of pediatric nephrologists is mandatory.

RESUMO

The adrenogenital syndrome is an autosomal recessive disorder in which an enzyme defect in the steroid pathway leads to excessive prenatal exposure of androgens. In the female fetus, masculinization of the external genitalia is observed. Surgery aims for functional and aesthetical reconstruction. Many techniques have been described. A video of our modified pull-through reconstruction technique is hereby presented. A retrospective descriptive database was created with patients who underwent genitoplasty for a CAH-associated genital condition. A video demonstrating the reconstructive technique was recorded while operating on a 9-month-old girl. Prior to surgery a cystoscopy is performed to evaluate the length of the urogenital sinus. Surgery starts with creating a reversed U-flap, after which the urogenital sinus is mobilized. The corpora cavernosa are released and the neurovascular bundle is isolated. To create vaginal space the urogenital sinus is subsequently separated. The vaginal introitus is anchored to the perineal skin flap. Labia minora are created by splitting the preputial skin. Finally excessive skin tissue is resected. Twenty-two female patients underwent reconstructive surgery for the adrenogenital syndrome in a tertiary referral centre over 16 years. Median age at surgery was 3 months (0-190). Median follow-up was 36 months (0-108) after surgery. A good functional and aesthetical outcome was observed. The modified pull-through technique, illustrated by this video, provided satisfactory results with a low complication rate. Follow-up until adulthood is needed to evaluate long-term outcomes.

RESUMO

Background. Isolated male epispadias (IME) is a rare congenital penile malformation, as often part of bladder-exstrophy-epispadias complex (BEEC). In its isolated presentation, it consists in a defect of the dorsal aspect of the penis, leaving the urethral plate open. Occurrence of urinary incontinence is related to the degree of dorsal displacement of the meatus and the underlying underdevelopment of the urethral sphincter. The technique for primary IME reconstruction, based on anatomic restoration of the urethra and bladder neck, is here illustrated. Patients and Methods. A retrospective database was created with patients who underwent primary IME repair between June 1998 and February 2014. Intraoperative variables, postoperative complications, and outcomes were assessed. A descriptive statistical analysis was performed. Results and Limitations. Eight patients underwent primary repair, with penopubic epispadias (PPE) in 3, penile epispadias (PE) in 2, and glandular epispadias (GE) in 3. Median age at surgery was 13.0 months [7-47]; median follow-up was 52 months [9-120]. Complications requiring further surgery were reported in two patients, while further esthetic surgeries were required in 4 patients. Conclusion. Anatomical restoration in primary IME is safe and effective, with acceptable results given the initial pathology.

RESUMO

OBJECTIVE: The aim was too demonstrate standardized video-urodynamic study (VUDS) in children using a transurethral catheter and pressure transducers. METHODS: Data necessary to obtain urodynamic evaluation of bladder sphincter function were gathered by concomitant measurement of bladder, urethral, and abdominal pressure. A 7F transurethral triple-lumen water-filled catheter was used for measuring the bladder and sphincter pressures and a water-filled 8F catheter connected to a pressure transducer was inserted into the rectum for pressure measurement. Cystometry was combined with fluoroscopy, providing simultaneous voiding cystourethrography information. Detrusor activity, bladder sensation, capacity, and compliance were measured during filling cystometry. Voiding cystometry consisted of recording pressures in the bladder sphincter and abdomen with simultaneous urinary flow measurement. RESULTS: Transurethral VUDS was safely and easily performed in a clinical setting adapted to children. CONCLUSIONS: A good and reproducible UDS is mandatory for correct therapeutic decisions. A standardized study associated with fluoroscopic assessment is presented in this video.

RESUMO

BACKGROUND: There is an ongoing quest on how to minimize complications in hypospadias surgery. There is however a lack of high-quality data on the following parameters that might influence the outcome of primary hypospadias repair: age at initial surgery, the type of suture material, the initial technique, and the type of hypospadias. OBJECTIVES: The objective of this study was to identify independent predictors for re-intervention in primary hypospadias repair. STUDY DESIGN: We retrospectively analyzed our database of 474 children undergoing primary hypospadias surgery. Univariate and multivariate logistic regression was performed to identify variables associated with re-intervention. A p-value <0.05 was considered statistically significant and therefore considered as a prognostic factor for re-intervention. RESULTS: Distal penile hypospadias was reported in 77.2% (n = 366), midpenile in 11.4% (n = 54) and proximal in 11.4% (n = 54) of children. Initial repair was based on an incised plate technique in 39.9% (n = 189), meatal advancement in 36.0% (n = 171), an onlay flap in 17.3% (n = 82) and other or combined techniques in 5.3% (n = 25). In 114 patients (24.1%) re-intervention was required (n = 114) of which 54 re-interventions (47.4%) were performed within the first year post-surgery, 17 (14.9%) in the second year and 43 (37.7%) later than 2 years after initial surgery. The reason for the first re-intervention was fistula in 52 patients (46.4%), meatal stenosis in 32 (28.6%), cosmesis in 35 (31.3%) and other in 14 (12.5%). The median time for re-intervention was 14 months after surgery [range 0-114]. Significant predictors for re-intervention on univariate logistic regression (polyglactin suture material versus poliglecaprone, proximal hypospadias, lower age at operation and other than meatal advancement repair) were put in a multivariate logistic regression model. Of all significant variables, only proximal hypospadias remained an independent predictor for re-intervention (OR 3.27; p = 0.012). DISCUSSION: The grade of hypospadias remains according to our retrospective analysis the only objective independent predicting factor for re-intervention in hypospadias surgery. This finding is rather obvious for everyone operating hypospadias. Curiously midpenile hypospadias cases were doing slightly better than distal hypospadias in terms of re-intervention rates. Our study however has also some shortcomings. First of all, data was gathered retrospectively and follow-up time was ill-balanced for several variables. We tried to correct this by applying sensitivity analysis, but possible associations between some variables and re-intervention might still be obscured by this. Standard questionnaires to analyze surgical outcome were not available. Therefore, we focused our analysis on re-intervention rate as this is a hard and clinically relevant end point. CONCLUSIONS: This retrospective analysis of a large hypospadias database with long-term follow-up indicates that the long-lasting debate about factors influencing the reoperation rate in hypospadias surgery might be futile: in experienced hands, the only variable that independently predicts for re-intervention is the severity of hypospadias, the only factor we cannot modify. This retrospective multivariate analysis of a large hypospadias database with long-term follow-up suggests that the only significant independent predictive factor for re-intervention is proximal hypospadias. In our series, technique did not influence the re-intervention rate.

RESUMO

PURPOSE: Total phalloplasty is rarely performed today in males with severe penile deficiency, despite its successful use in the transgender population. Can phalloplasty replicate the complexity of penile anatomy and function on the long term? METHODS: Sexual quality of life (QoL) was assessed in 10 men (aged 20-43 years) at least 1 year after phalloplasty in a single institution (80 % radial forearm flap and 20 % anterolateral thigh flap). In all but one, an erectile prosthesis was implanted on average 1 year after phallic reconstruction. Sexual QoL outcomes were compared to those of men with hypospadias repair (n = 73) and control men (n = 50). RESULTS: After phalloplasty (mean 36.9 months, 14-92 months), all men were sexually active (80 % intercourse and 100 % masturbation with orgasm and ejaculation). However, 75 % indicated to be inhibited in seeking sexual contacts, compared to 40 % of hypospadias patients (p < 0.05) and 11 % of controls (p < 0.01). Although 90 % were satisfied with the final surgical result, dissatisfaction with some aspects of genital appearance was present in 50 %. Erogenous neophallus sensitivity was said to be less than previously hoped for. Six men developed urinary complications (urethral stricture and/or fistula), and one man underwent revision of the erectile implant because of dysfunction. Nevertheless, all indicated they would choose again for phalloplasty if necessary. CONCLUSIONS: Total phalloplasty opens new horizons for the treatment of men with penile deficiency, but limitations of the technique should be emphasized prior to surgery. An exploration of patient expectations and continued follow-up including psychological support is important for optimizing psychosexual comfort.

RESUMO

INTRODUCTION: Buried penis is a pathology for which several reconstructive techniques are described. We report our technique and its outcome. PATIENTS AND METHODS: 75 patients underwent repair of buried penis by one surgeon (P.H.) between 1997 and 2011. The first 17 patients (mean age 2.6 years) underwent skin-sparing circumcision. The next 58 patients (47 children, mean age 4.4 years; 11 adults, mean age 38 years) underwent our new technique. Its key point consists in releasing dartos tissue and in anchoring the corpora cavernosa to dartos bundles at the penile base. Outcome was evaluated by reoperation rate, complications and satisfaction according to surgeon/patients/parents. RESULTS: The results of skin-sparing circumcision performed in 17 children at 1 year were reported as good by the surgeon in 62.5% (n = 10) and in 82.4% (n = 14) by patients. Reoperation for recurrence occurred in 29.4% (n = 5) patients. Complications treated conservatively were reported in 35.3% (n = 6) of the children. The new technique was performed in 58 patients (47 children, 11 adults). The results were reported as good by the surgeon in 96.6% (n = 56) and in 91.4% (n = 53) by patients. Reoperation occurred in 4 patients (6.9%). CONCLUSIONS: The outcome of the new technique is superior to skin-sparing circumcision regarding complication/reoperation rate and cosmesis according to patients/parents/surgeon.

RESUMO

PURPOSE: The field of reconstructive surgery for hypospadias is lacking standard techniques and followup. Most published series include complication rates after a short followup. We report and analyze the long-term outcome of primary hypospadias repair at a single tertiary care center. MATERIALS AND METHODS: We reviewed 1,061 operations performed at our institution between 1997 and 2010 and registered as hypospadias repair. The operations were performed in 543 patients born between June 1997 and June 2005. A retrospective database was created with information about hypospadias characteristics, surgery and followup. RESULTS: A total of 474 primary repairs were selected, excluding incomplete/incorrect files. Distal penile hypospadias was reported in 366 patients (77.2%), mid penile hypospadias in 54 (11.4%) and proximal hypospadias in 54 (11.4%). Initial repair technique was based on incised plate in 189 patients (39.9%), meatal advancement in 171 (36%), onlay flap in 82 (17.3%) and other or combined techniques in 25 (5.3%). Insufficient information was reported for 7 patients (1.5%). Mean age at first operation was 22.6 months (range 4 to 134) and mean followup after first operation was 34.0 months (0 to 145). Of the children 360 (75.9%) had a good long-term outcome and required only 1 procedure. Reoperation was needed in 114 patients (24.1%), of whom 54 (47.4%) underwent reoperation in the first year of followup. CONCLUSIONS: Overall a good long-term outcome without further complication was achieved in 75.9% of our cases. Of the 24.1% of patients who needed reoperation only 47.4% presented within the first year postoperatively, indicating the need for long-term followup when reporting outcomes of hypospadias repair.

RESUMO

OBJECTIVE: To determine the outcome of urethroplasty for failed hypospadias repair and to compare this with a matched cohort of patients treated with urethroplasty for other reasons. PATIENTS AND METHODS: Between January 2000 and August 2007, 25 patients with a failed hypospadias repair were treated with urethroplasty (A). This cohort of patients was matched with a cohort of 25 patients who underwent urethroplasty for other reasons (B). The patients were matched for stricture location, stricture length, duration of follow up and type of urethroplasty. The outcomes were analysed and compared. A P-value < 0.05 was considered statistically significant. RESULTS: There were no significant differences between the two cohorts in stricture location, stricture length, follow up and previous interventions. Patients in cohort A however were significantly younger. The surgical technique used was exactly the same in A and B. Failure was observed in 7 patients (28%) in A compared to 4 patients (16%) in B (P = 0.45). CONCLUSIONS: Although a higher failure rate was observed after failed hypospadias repair, this is not proof of a worse outcome for urethroplasty after failed hypospadias repair due to the lack of statistical significance.

RESUMO

OBJECTIVE: To assess the long-term outcome of continent diversion in children with structural or neurogenic cause of incontinence, with special interest in differences between closed and open bladder neck procedures. PATIENTS AND METHODS: A cohort of 63 children with intractable incontinence treated with continent diversion between January 1998 and January 2008 were reviewed for underlying disease, type of surgery, complications and outcome. RESULTS: Forty patients had a continent diversion with open bladder neck (group 1) and 23 patients had their bladder neck closed (group 2: 11 primarily closed; 12 secondarily closed). There was no difference between the two groups in terms of patient characteristics, surgical re-interventions and stone formation. The continence rate however was significantly better in group 2 (95.6% vs 77.5%). CONCLUSION: Bladder neck closure with continent diversion as primary or salvage procedure in children with intractable incontinence does not result in extra morbidity and has a high success rate. Thorough urodynamic evaluation of bladder function is the key to success in therapy planning for these children, to minimize the need for re-intervention.
