Multicenter comparative study of open, laparoscopic, and robotic pyeloplasty in the pediatric population for the treatment of ureteropelvic junction obstruction (UPJO).

Introduction: Dismembered open pyeloplasty described by Anderson and Hynes is the "gold standard" for the treatment of ureteropelvic junction obstruction. The aim of our study was to compare the results of open (OP) vs laparoscopic (LP) vs robotic (RALP) pyeloplasty.

Material And Methods: A multicenter prospective review was conducted of pyeloplasty surgeries performed at five high-volume centers between 2014 and 2018.

Congenital Bladder Prolapse Through a Patent Urachus: Two Institutions' Experience.

We describe our experience in 2 institutions handling bladder prolapse through a patent urachus (PU), together with a brief review of published literature. Case 1: A term neonate with congenital prolapsed bladder via PU. Ultrasound at 21 weeks gestation revealed a male fetus with a large midline pelvic cyst communicating with the bladder which disappeared on subsequent 27 weeks ultrasound.
