INTRODUCTION: Among urologic diseases, ureteropelvic segment stenosis with hydronephrosis is a common indication for instrumental or surgical correction. The restriction of urine flow with dilatation proximal to obstruction develops in 6.5-37% of cases at different times after the ureteral reconstruction. All this urges to develop and improve stents and search for effective ways to place stents and control their function. AIM: To investigate the effectiveness of polyhydroxyalkanoates based biodegradable stent compared with a commercial analogue in upper urinary tract drainage after ureteropelvic segment pyeloplasty...

William R Boysen, Mohan S Gundeti
Ureteropelvic junction obstruction is a common condition encountered by the pediatric urologist, and treated with pyeloplasty when indicated. Recent technological advancements and a shift across all surgical fields to embrace minimally invasive surgery have led to increased utilization of minimally invasive pyeloplasty. Conventional laparoscopy is a reasonable choice, but its use is limited by the technical challenges of precise suturing in a confined space and the associated considerable learning curve. Robotic technology has simplified the minimally invasive approach to pyeloplasty, offering enhanced visualization and improved dexterity with a fairly short learning curve...

Robotic assisted laparoscopy pyeloplasty (RALP) has been associated with shorter recovery, less pain and improved cosmesis. To minimize visible scars, the hidden incision endoscopic surgery (HIdES) trocar placement has been previously developed. Our aim was to compare outcomes between the HIdES and traditional port placement (TPP) for pediatric RALP. A retrospective study was performed on patients under 15 years of age who underwent RALP at a single institution between August 2011 and November 2013. Patient demographics, intraoperative details, narcotic administration, and complications were reviewed...

Non-absorbable Hem-o-Lok clips are commonly used for vascular pedicle control or suture stabilisation during laparoscopic or robotic reconstructive procedures. As they are placed close to suture line and with tension, these clips have a propensity to migrate. We report a case of a 22-year-old man with history of bilateral robotic pyeloplasty presenting with left inferior calyceal stone. He underwent left mini percutaneous nephrolithotomy which revealed an encrusted migrated Hem-o-Lok clip that was used to close the mesenteric window formed during transmesocolic pyeloplasty...

INTRODUCTION: Patient age and hospital volume have been shown to affect perioperative outcomes after pediatric pyeloplasty. However, there are few multicenter studies that focus on outcomes at teaching hospitals, where many of the operations are performed. OBJECTIVE: The goal was to determine if surgical approach, age, case volume, or other factors influence perioperative outcomes in a large contemporary cohort. STUDY DESIGN: Using the clinical database/resource manager (CDB/RM) of the University Health-System Consortium (UHC), children who underwent open, laparoscopic, or robotic pyeloplasty from 2011 to 2014 were identified at 102 academic institutions...
