Endoscopic incision of persistent ureteral infoldings.
We report 2 cases of persistent ureteral infolding in a four-month-old infant and an eight-year-old boy, both presenting with hydronephrosis. Initial diagnostic evaluation showed multiple pleats in the upper ureter. Endoscopic incision of the pleats relieved hydronephrosis. The concept of persistent ureteral infolding seems to apply to these cases.
