Neonatal ascites and ureteral valves

Urology. 1989 Jun;33(6):468-71. doi: 10.1016/0090-4295(89)90133-7.


We report a case of neonatal urinary ascites in a newborn, presenting with a large communicating hydrocele. Initial diagnostic evaluation revealed high-grade ureteropelvic junction obstruction in a solitary functioning kidney with a nonobstructive megaureter. After pyeloplasty and with changing transitional nephrology, the megaureter became obstructive requiring tailoring and reimplantation. The unifying concept of ureteral valves explaining this case is presented.
