"Watering Can" Ureterocele Puncture Technique Leads to Decreased Rates of De Novo Vesicoureteral Reflux and Subsequent Surgery With Durable Results.

Objective: To assess the outcomes of "watering can" ureterocele puncture (WCP), a technique previously associated with decreased incidence of de novo vesicoureteral reflux (VUR), as a durable option for management of ureteroceles and to determine the need for subsequent surgery for VUR following watering can puncture.

Materials And Methods: We retrospectively reviewed records of 55 consecutive endoscopic ureterocele procedures performed at our institution from 1999 to 2015. The WCP was performed using a holmium laser fiber to make 10-20 puncture holes through the ureterocele.

Comparison of endoscopic ureterocele decompression techniques. Preliminary experience--is the watering can puncture superior?

Purpose: The optimal endoscopic technique to manage an obstructing ureterocele would reliably relieve obstruction without creating de novo vesicoureteral reflux. The classic incision achieves decompression but invariably creates new vesicoureteral reflux. We compared a new endoscopic puncture technique to assess its superiority to endoscopic incision.
