[Clinical results of endourologic technique for upper urinary calculi].

Between May, 1985 and September, 1987, percutaneous nephrolithotripsy (PNL) and transurethral ureterolithotripsy (TUL) have been performed at our hospital and five affiliated hospitals. We report on the therapeutic results of 216 cases treated during this period. PNL and TUL were performed 168 times on 120 patients (119 males and 41 females) and 57 times on 56 patients (35 males and 21 females), respectively. Rate of success with PNL was 80.7% (103/130) for renal calculus, 85.7% (18/21) for upper ureteral calculus, and 47.1% (8/17) for middle-lower ureteral calculus. Rate of success with TUL was 57.9% (33/57). Of these, cases of ureteral lower edge calculus showed the lowest rate of success, being 33.3% (2/6). Complications of the cases undergoing PNL and TUL were: ureteral damage in 13; hemorrhage in 6; renal pelvic damage in 4; ureteral lower edge stenosis in 3; pyrexia in 3; cardiac insufficiency in 2 and retention of perfusate in posterior peritoneal cavity, pneumonia and renal insufficiency in 1 case each.
