15例の尿路結石症以外の上部尿路の狭窄病変に対し内視鏡的拡張を行い,11例に良好な結果を得た.4例の上部尿路腫瘍を疑った症例に対し内視鏡的観察を行い全例に確診を得たFifteen patients with stricture of upper urinary tract and 4 patients suspected of having upper tract carcinoma were managed with endourological (percutaneous or transurethral) techniques. The strictures were treated with various dilation catheters and the optical urethrotome. Eleven cases (73.3%) were successfully treated and satisfactory urinary passage was attained. The 4 patients suspected of having upper tract neoplasms were diagnosed accurately with endoscopy, 2 patients had transitional cell carcinoma of renal pelvis and the others had benign ureteral polyps. The endourological technique was a useful method for the treatment of ureteral stenosis and the diagnosis of upper tract neoplasm except for the treatment of urolithiasis. This technique will become useful tool in urology.
