A 38-year-old woman was seen with a complaint of pollakisuria and constant urinary urgency. Ultrasonography; plain radiography of her kidney, ureter, and bladder; and intravenous urography revealed bilateral ureteroceles with calculi. Bilateral transverse incision of the ureteroceles and lithotripsy were performed using a transurethral approach. At 8 months postoperatively, voiding cystography revealed the absence of vesicoureteral reflux. Although controversies remain about the effectiveness of endoscopic incision because of the risk of vesicoureteral reflux, endoscopic management with a transverse incision is well tolerated for such cases.
