PURPOSE: We compared the outcomes in patients who were <1 year old and had hydronephrosis with SFU grade 3-4 PUJ obstruction to observe the potential recovery of renal morphology and DRF after successful pyeloplasty. METHODS: All children younger than 1 year old with SFU grade 3-4 PUJ obstruction from January 2013 to June 2015 were retrospectively analyzed. A total of 92 children were grouped according to their DRF value at pyeloplasty as follows: DRF from 30 to ≤35% (group I) and DRF from 35 to ≤40% (group II)...

OBJECTIVE To present the use of buccal mucosal graft (BMG) in a salvage robotic laparoscopic pyeloplasty as an alternative in the management of recurrent UPJ obstruction. METHODS We present two patients with recurrent UPJ obstruction who had previously undergone two prior open or robotic pyleoplasties, followed by endoscopic management. Preoperative imaging was obtained prior to surgical repair. The UPJ was incised and the incision extended to reveal margins of healthy normal caliber ureteral tissue. Single buccal mucosal graft were harvested from the inner cheek of each patient...

INTRODUCTION: To analyze the most recent temporal trends in the adoption of urologic laparoendoscopic single-site (LESS), to identify the perceived limitations associated with its decline, and to determine factors that might revive the role of LESS in the field of minimally invasive urological surgery. METHODS: A 15 question survey was created and sent to members of the Endourological Society in September 2016. Only members who performed LESS procedures in practice were asked to respond...

INTRODUCTION AND OBJECTIVE: Retroperitoneal access for robotic renal surgery is an effective alternative to the commonly used transperitoneal approach. We describe our contemporary experience and technique for attaining retroperitoneal access. MATERIALS AND METHODS: We outline our institutional approach to retroperitoneal access for the instruction of urologists at the beginning of the learning curve. The patient is placed in the lateral decubitus position. The first incision is made just inferior to the tip of the twelfth rib as described by Hsu, et al...

BACKGROUND: Laparoendoscopic single-site (LESS) surgery and minilaparoscopy (ML) represent the evolution of laparoscopy for the treatment of urologic diseases. OBJECTIVE: To describe the technique and report the surgical outcomes of minilaparoendoscopic single-site dismembered pyeloplasty (MILESS-DP), a new technique overcoming the technical limitations of LESS and ML, and equally combining the advantages of both these surgical procedures. DESIGN, SETTING, AND PARTICIPANTS: Twenty consecutive patients underwent MILESS-DP for ureteropelvic junction obstruction...

AIM: To investigate the correlation between the status of interstitial cells of Cajal (ICC) in ureteropelvic junction (UPJ) and the resected ureteric margin and the postoperative outcome of Anderson-Hynes pyeloplasty in UPJ obstruction (UPJO) and to compare the ICC in the UPJ and the resected margin of the normal ureter. MATERIALS AND METHODS: An observational study was conducted over a period of 2 years at the Department of Pediatric Surgery at Niloufer Institute of Women and Child Health...

OBJECTIVE: Ureteropelvic junction obstruction (UPJO) is a common cause of symptomatic ureteral obstruction. The aim of this study is to assess the outcome of laparoscopic pyeloplasty in patients with UPJO. PATIENTS AND METHODS: Medical reports of 47 UPJO patients treated with laparoscopic pyeloplasty were retrospectively analysed. All patients were recruited from our center in the period 2004-2011. RESULTS: We evaluated 47 patients. Mean age was 36 years and mean hospital stay 3...

BACKGROUND: Ureterocalicostomy is indicated mainly in cases with failed pyeloplasty or with a completely intrarenal pelvis. While there have been several case series reported in adults, laparoscopic ureterocalicostomy in pediatric cases has rarely been reported. We report a case of pure laparoscopic ureterocalicostomy for ureteropelvic junction obstruction in an Asian female child. CASE PRESENTATION: A 10-year-old female patient was referred to our hospital due to right high-grade hydronephrosis and a right renal stone, which was detected due to hematuria...

INTRODUCTION: Ureterocalicostomy (UC) is a well-established treatment option for patients with recurrent ureteropelvic junction obstruction (UPJO) with postoperative fibrosis and a relatively inaccessible renal pelvis. This study aimed to evaluate the long-term outcome of UC and factors predicting its failure. MATERIALS AND METHODS: We retrospectively analysed data of 72 patients who underwent open or laparoscopic UC from 2000 to 2014. Variables that may affect the outcomes of UC were assessed with regard to primary pathology, age, serum creatinine, preoperative renal size (<15 cm and > 15 cm), renal cortical thickness (<5mm and >5 mm), grade of hydronephrosis and preoperative renal function (GFR < or >20 ml/min)...

Robotic upper urinary tract reconstruction (UUTR) has been widely utilized for surgical management of congenital obstruction. To further reduce morbidity and simplify postoperative care, outpatient robotic pyeloplasty (RP) and robotic ureteroureterostomy (RUU) were performed without ureteral stents, drains, or urethral catheters. The aim of the study was to assess the safety of performing tubeless robotic UUTR as an outpatient procedure. A retrospective review was performed for patients who underwent outpatient tubeless RP and RUU between July 2015 and January 2017...

INTRODUCTION: Laparoscopic pyeloplasty has achieved good cosmetic and functional outcomes. Both transumbilical single-site and transumbilical multi-port approaches are currently being used. No comparison of transumbilical single-site laparoscopic pyeloplasty (TSLP) and transumbilical multi-port laparoscopic pyeloplasty (TMLP) has been reported in the literature. OBJECTIVES: We present a retrospective comparison study to evaluate clinical outcomes of TSLP and TMLP for children with ureteropelvic junction obstruction (UPJO)...

OBJECTIVE: To report our experience on gas endoscopy as the first step of pelvi-ureteric junction (PUJ) obstruction repair when complicated by nephrolithiasis. MATERIALS AND METHODS: Stone formation due to urine stasis is a known complication PUJ obstruction and an indication for its surgical repair. The undisputed results of the Anderson-Hynes dismembered pyeloplasty make it a quasi-gold standard; however, the identification and extraction of calyceal stones through the laparoscopic route can be challenging...

OBJECTIVES: To assess the optimal length of follow-up for patients undergoing both open and minimally invasive pyeloplasties to ensure prompt detection of a recurrent obstruction. There are no standard guidelines on ideal follow-up and imaging post-pediatric pyeloplasty currently. METHODS: A retrospective chart review identified 264 patients (<18 years old) who underwent pyeloplasty for ureteropelvic junction obstruction between April 2002 and December 2014...

OBJECTIVE: To determine the clinical value of visually assessed renal tissue transit time (TTT) in (99m)Tc-mercaptoacetyltriglycine ((99m)Tc-MAG3) renography for patients undergoing pyeloplasty. MATERIALS AND METHODS: Medical records of 164 patients who underwent dismembered pyeloplasty were retrospectively reviewed. Baseline and postoperative renal ultrasonography and (99m)Tc-MAG3 renography were performed. Two urologists blinded to clinical data evaluated the renography and classified TTT as timely or delayed based on visualization of the tracer in the kidney pelvis between 2 and 10 minutes...

BACKGROUND: This article aimed to evaluate the outcome of laparoscopic vascular hitch (VH) as an effective alternative to dismembered pyeloplasty in the treatment of children with extrinsic ureteropelvic junction obstruction (UPJO) by crossing vessels (CVs), by reporting the experience of three Italian centers of Pediatric Surgery. METHODS: From 2006 to 2014, 54 children (18 girls and 36 boys, average age 10.7 years) affected by suspected extrinsic UPJO by CV were treated in three different institutions: 51 patients underwent laparoscopic VH, while 3 patients, in which a coexisting intrinsic etiology of UPJO was doubtful, underwent laparoscopic dismembered pyeloplasty...

Literature data comparing robotic-assisted laparoscopic versus retroperitoneoscopic approaches are still lacking, probably due to difficulties with the retroperitoneoscopic approach. The objective is to compare the results of robotic-assisted pyeloplasty using transperitoneal and retroperitoneal approaches in a prospective randomised single surgeon study. 80 consecutive patients with primary ureteropelvic junction obstruction were prospectively randomised between transperitoneal (40 patients, group 1) and retroperitoneal (40 patients, group 2) robotic-assisted pyeloplasty...
