PURPOSE: To retrospectively evaluate the safety and effectiveness of holmium laser endoscopic incision and laser lithotripsy in adults with orthotopic ureterocele and associated calculi. PATIENTS AND METHODS: From May 2003 to August 2007 at our center, 16 adults underwent transurethral incision of an ureterocele and intracorporeal holmium laser lithotripsy for associated calculi. The perioperative data of these patients were retrospectively analyzed. The literature was reviewed to identify all the reported options for management of this relatively rare condition. RESULTS: Ureterocele was associated with a single system in 13 patients. Two patients had bilateral ureteroceles. Four patients had associated upper tract stones. The procedure was uneventful in all patients. The average postoperative hospital stay was 19.3 hours. All patients were stone free after the procedure. Eleven patients were available for follow-up at 3 and 6 months. None of these patients had any evidence of residual ureterocele and/or hydronephrosis when evaluated with intravenous urography at 3 months. Micturating cystourethrography (MCU) at 3 months revealed low-grade vesicoureteral reflux (VUR) in four patients; no reflux was found with MCU at 6 months. CONCLUSIONS: Laser endoscopic management of adult orthotopic ureterocele and associated calculi effectively decompressed ureterocele and removed stones in all patients without any significant postoperative morbidity. Low-grade VUR that may occur postoperatively resolved at 6 months. A literature review suggests that the ability of the holmium laser to manage both ureterocele and calculi simultaneously should make holmium laser management a procedure of choice at centers that possess the equipment.
