RESUMO
PURPOSE: To report our experience and results in terms of complications, reoperation rate and urinary continence with the Salvage Continent Vesicostomy (SCV) technique in pediatric patients with history or need of enterocystoplasty and absent appendix. METHODS: Retrospective review of all patients with a history of a continent catheterizable channel surgery performed in our institution between June 2016 and January 2022. Only patients with a SCV surgery with a minimum 6-month post operative follow up were included in this cohort and divided in group 1 (history of previous bladder augmentation) and group 2 (simultaneous bladder augmentation and SCV). Primary outcome of the study was to assess both continence and postoperative complication rates. Early complications were assessed using the Clavien-Dindo classification (I-V). Late complications were focused on the need of further subfascial revision. RESULTS: 84 patients with a history of a continent stoma creation surgery were identified. In 20 of them (12 males) a SCV was performed. The mean age at surgery was 10.38 (range 4.87-15.6) years and the median postoperative follow-up time was 32 (range 6-64) months. Eleven patients were included in Group 1, while 9 patients in Group 2. Early complications occurred in 4 patients (20%), two of them required a re-intervention (Clavien-Dindo IIIb). Stoma subfascial revision was further required in 2 patient (10%). Continence rate at last follow up was 95%. CONCLUSIONS: In our early experience, the salvage continent vesicostomy has proven to be a simple continent stoma technique with acceptable both continence and complication rates that can be used in selected patients with a history or need of bladder augmentation and absent appendix.

INTRODUCTION: The proactive management of spina bifida (SB), especially of its severe form, myelomeningocele (MMC), has contributed to decreasing chronic kidney disease (CKD). The objective of this study is to present the evolution of 5-year-old patient with MMC followed from birth with a proactive approach. MATERIAL AND METHODS: This retrospective study included 55 cases with MMC of up to 5 years of age. All of them were admitted at birth and followed by a multidisciplinary group, with a proactive approach: CIC and anticholinergics. In the same group, the variables were compared within the first year and the within the fifth year of life. Chronic kidney disease (CKD) was defined by: alterations on renal DMSA scintigraphy; alterations in microalbuminuria/creatininuria ratio, proteinuria 24 hs and decrease in glomerular filtration rate (GFR) calculated with Schwartz bedside equation. RESULTS: Although overactivity, UTI and VUR decreased throughout the first 5 years (49, 9 and 12%), reduced cystometric capacity, DLPP >40 cm of water and end-filling pressure (Pdet) >20 cm of water increased (41, 27 and 61%). All patients at 5 years of age required CIC. Reduced cystometric capacity and VUR were more significant with abnormal DMSA (36%) at 5 years old ( p: 0.03). Proteinuria and CKD increased to 25% and 49%. Similarly, the need for enalapril increased from 10% to 27%. The microalbuminuria/creatininuria ratio was pathological in 27.3%. 48 patients (87%) remained unchanged on DMSA scan and the other 7 underwent modifications (4 new cases with altered DMSA) over time. Of the 32 normal DMSA cases without changes, 81% did not present proteinuria and 88% continued to respond favorably to oxybutynin. GFR <90 ml/min/1.72m 2 was found in only 3 cases with abnormal DMSA. There was a RR 1.91 (IC95% 1.15-3.16) greater of renal compromise in cases that were anticholinergic-resistant compared to non-refractory cases. DISCUSSION: Over time, some patients suffered loss of bladder wall compliance, despite the proactive approach. There is an association between abnormal renal DMSA, reduced bladder capacity, and VUR at 5 years of age. Although proteinuria, CKD and enalapril requirement increased over 5 years, almost 90% did not show changes in renal DMSA status. CONCLUSIONS: Over time, some patients suffered loss of bladder wall compliance. Hence, even if a proactive approach is followed since birth, it is essential to continue with the ongoing monitoring of the renal status and thus avoid greater renal deterioration.

OBJECTIVE: To describe the effects of oral sirolimus administered before and after surgical resection of slow-flow vascular malformations of the scrotum in pediatric patients. METHODS: Retrospective review of 3 patients presenting with complex lymphatic-venous malformations of the scrotum who received adjuvant oral sirolimus 3 months before and 3 months after surgical resection. Demographic data, clinical course, imaging findings, and management strategies were reviewed for each patient. RESULTS: In each of the 3 patients, there was a significant volume reduction of the lesion within the 3 months after initial dose of sirolimus. Scarce lymphatic leakage during and after surgery was reported, associated with an adequate wound healing. Two years after the last postsurgical dose of sirolimus, all patients remain asymptomatic without any lymphatic leakage or lesion recurrence. CONCLUSION: Combined lymphatic-venous vascular malformations of the male genitalia are rare but associated with high morbidity and challenging treatment options. Pre- and postsurgical adjuvant treatment with oral sirolimus seems to be a promising therapeutic option that provides reduction of the lesion size before surgery and improvement of postsurgical recovery and wound healing.

OBJECTIVE: To analyze the outcomes of patients undergoing upper-pole heminephrectomy surgery and to assess the different variables that may have an impact on outcome, specifically regarding morbidity and the need for further surgeries. MATERIALS AND METHODS: A retrospective study of patients who underwent laparoscopic upper-pole heminephrectomy for a nonfunctional moiety between August 2007 and December 2019 was conducted at 3 centers. A total of 130 patients met the inclusion criteria. A transperitoneal approach was used. The following variables were evaluated: (1) preoperative: presentation, presence of ureterocele and history of ureterocele incision, hydronephrosis grade, presence of vesicoureteral reflux (VUR), and differential renal function (DRF) on renal scintigraphy; and (2) postoperative outcomes: Doppler ultrasound, renal scintigraphy, complications, febrile urinary tract infection, lower urinary tract symptoms, and need for further surgery. Findings were considered statistically significant at P <.05. RESULTS: Postoperative complications were observed in 5 patients (3.8%). Six patients (4.6%) needed further surgeries after heminephrectomy. The presence of ureterocele and VUR was related with the need for further surgeries odds ratio (OR) 4.91, P = .0415) and the occurrence of postoperative febrile urinary tract infection (OR 2.81, P = .0376). A 13.9% incidence of lower urinary tract symptoms was found with no difference between patients with ureterocele and those with an ectopic ureter. Renal scintigraphy showed a median decrease in DRF of 2.7%. No patient had complete loss of function. CONCLUSION: Laparoscopic upper-pole heminephrectomy showed to be a feasible and safe procedure. In most patients this surgery will be the definitive procedure. Patients with both VUR and ureterocele will need special consideration. No significant loss of function in the remaining lower moiety was found.

PURPOSE: Preserving renal function and achieving urinary continence are the most important urological goals in the management of cloaca patients. Many prognostic factors have been described, such as the length of the common channel (CC) and urethra, the presence of spinal dysraphism, and associated urological anomalies. The aim of this study was to analyze urinary continence status and need for reconstructive procedures and their correlation with urological risk factors in a series with a long-term follow-up. MATERIAL AND METHODS: The institutional database of patients with anorectal malformations was reviewed. Patients with cloaca who underwent cloacal reconstructive surgery at our institution between January 1995 and May 2015 and who had a minimum postoperative follow-up of 5â¯years with complete urological care were included. Urologic and spinal anomalies, length of the CC, renal function, urodynamic study patterns, continence status, and urologic reconstructive surgeries were assessed. A CC was defined as long CC when its measure was longer than 3â¯cm in the cloacogram and then confirmed by cystoscopy. Descriptive statistical analysis was performed. RESULTS: Fifty-five cloaca patients with a mean follow-up of 12â¯years (5-20) were included. A long CC was documented in 38 patients (69%). The sacral ratio (SR) was <0.4 in the AP projection in 30 (54.5%). Urodynamic evaluation revealed an inadequate detrusor contraction pattern in 65.4% of the cases. A CC >3â¯cm and SR <0.4 were significantly correlated with this urodynamic finding. A total of 50 patients (91%) achieved urinary continence, but only 30.9% had volitional voiding and 56% needed major urological reconstructive surgeries. Eighteen patients (32.7%) were in stage 2 or more of chronic kidney disease (<90â¯ml/min/1.73â¯m2) at the last follow-up visit. CONCLUSION: Cloacal management requires a multidisciplinary and long-term follow-up. Early assessment of prognostic urological factors and accurate stratification of each patient are essential to avoid renal impairment and achieve urinary continence in the future. The length of the common channel and the presence of spinal dysraphism were correlated with the presence of neurovesical dysfunction specifically an abnormal bladder contraction efficiency. A significant number of these patients will need catheterization and reconstructive urinary tract surgeries to attain urinary continence. TYPE OF STUDY: Retrospective study. LEVEL OF EVIDENCE: Level 3. Retrospective comparative study.

INTRODUCTION: Simultaneous bilateral endoscopic surgery (SBES) is the performance of a percutaneous nephrolithotomy (PCNL) on one side and a retrograde intrarenal surgery (RIRS) on the other kidney simultaneously. OBJECTIVE: Our aim is to report through a video the surgical technique and the step-by-step details of a SBES performed in a pediatric patient. PATIENTS AND METHODS: A 12-year-old male patient with bilateral upper tract urolithiasis. RESULTS: Supine PCNL is performed in Galdakao-modified Valdivia position. Ureteroscopic surgeon performs retrograde pyelography on PCNL kidney. Percutaneous access under fluoroscopic guidance trough the lower calyx and dilated with Amplatz dilators to 17.5 Fr. Storz® 17.5 MIP Nephroscope is introduced and fragmentation with pneumatic lithotripter starts. On the other kidney, after introduction of ureteral sheet 12/14 Fr and digital flexible ureteroscope Flex Xc ® 9.5Fr, pulverization of the stone starts with Laser Holmium YAG (Oddysey®). Surgeons work simultaneously and share fluoro-scopic c-arm. CONCLUSION: SBES can be reproduced in children. Proper planification and preparation of the involved team and OR set up are essential. Further prospective randomized studies are needed to establish safety and efficacy of SBES in pediatric patients.
