Urinoma, defined as an encapsulation of urine caused by urine extravasation into the perirenal space either through rupture of a calyceal fornix or a tear in the renal parenchyma, is an uncommon finding in prenatal diagnosis and the neonatal period. Urinoma can be associated with any urinary tract obstruction, or, as reported in several published cases, related to vesicoureteral reflux, kidney dysplasia, or complication arising during amniocentesis. We report on a newborn with a perinatal urinoma, with initial slight corpusculated fluid associated with nonobstructive and nonrefluxing megaureter, and no signs of kidney dysplasia.

Surgical treatment of pediatric kidney stones has changed dramatically in recent years because of the miniaturization of surgical instruments and the availability of intracorporeal lithotripters. The retrograde intrarenal surgery (RIRS) technique is nowadays considered an effective and safe procedure but studies in very young children are lacking and use of a ureteral access sheath (UAS) has also been debated.
To assess safety and efficacy of RIRS using UAS in children weighing < 20 kg.

Pre-operative physical examination of male epispadias allows for classification of epispadias level as glanular (GE), penile (PE) or penopubic (PPE), and for delineation of anatomic anomalies. The incidence of associated extragenital abnormalities, such as vesicoureteral reflux (VUR), bladder neck (BN) abnormality and abnormal pubic diastasis (PD), and their impact on urinary continence has not yet been systematically studied.
The goal of this study was to evaluate whether the more proximal level of epispadias correlated with associated extragenital anatomic anomalies seen on initial imaging or endoscopic evaluation, and whether these pre-operative findings contributed to subsequent surgical management and impacted on achieving urinary continence.

BackgroundFibroblast growth factor receptor 2 (Fgfr2) deletion from murine peri-Wolffian duct stroma (ST) results in aberrant ureteric bud induction, abnormal ureteral insertion into the bladder, and high rates of vesicoureteral reflux (VUR). It is unclear which receptor docking protein(s) is/are responsible for Fgfr2 actions in these tissues. We investigated whether the docking protein, fibroblast receptor substrate 2α (Frs2α), had a role in peri-Wolffian duct ST similar to Fgfr2.
