Bilateral ectopic ureteroceles are extremely rare. There are few reports of bilateral duplex system with ureterocele stone formation. Our case report represents a 35-year-old woman with bilateral complete ureteral duplication and stone in a right sided ureterocele. A Bugbee electrode was used to puncture the ureterocele at its most dependent part followed by fragmenting the stone using pneumatic lithotripsy. Management of the ureterocele stone depends mostly on stone size. Whereas smaller stones are amenable to endoscopic incision and lithotripsy, larger ones have required combination therapy with endoscopic incision, laser or pneumatic lithotripsy and even orificiotomy and ureterolithotomy.
