Background and Objectives The feasibility of treating upper urinary tract tumors with a holmium:YAG (Ho:YAG) laser in transurethral endoscopy was examined. Study Design/Materials and Methods Thirty‐three treatments were performed on 30 patients with renal pelvic and ureteral carcinomas. After vaporization and coagulation eliminated the tumors, the surrounding mucosa was fully coagulated. Postoperative follow‐up consisted of urinary cytology once a month, cystoscopy every 3 months, excretory pyelography every 6 months, and uretero‐pyeloscopy every 6–12 months. Results The recurrence rate after the first treatment was 86% in the imperative indication group. The tumor‐free rate (median follow‐up, 37 months) in the imperative indication group was 57%. In the elective indication group, those values were 20 and 95% (median follow‐up, 33 months), respectively. Conclusions Transurethral endoscopic treatment of upper urinary tract tumors using Ho:YAG laser can be a useful method on limited cases identified into specific treatments groups combined with a strict follow‐up.
