Abstract

Objective: To analyze the short and long term safety and efficacy of ureteroscopic evaluation and management of chronic unilateral hematuria. Methods: We retrospectively reviewed patients with chronic unilateral hematuria from 1987 to 2008. The distal to middle ureter was evaluated with a semi-rigid ureteroscope without a guidewire. Subsequently, the flexible ureteroscope was advanced into the upper ureter to the renal pelvis using a low-pressure automated irrigant system (Uromat™). Lesions identified ureteroscopically were treated with diathermy fulguration. Results: One hundred and four (56 male, 48 female) patients were identified, with a median age of 37 (14-80) years and median follow-up of 139 (34-277) months. The median preoperative duration of gross hematuria was 5 (1-144) months. Endoscopic findings included 61 (56%) minute venous rupture (MVR; a venous bleeding without clear abnormalities), 21 (20%) hemangioma (vascular tumor-like structure), 3 (3%) varix (tortuous vein), 1 (1%) calculus and 18 (17%) no lesions. The incidence of "no lesions" was less in the recent 12 years (9%) than the first 10 years (27%), while the incidence of MVR increased from 40 to 66% (p
