Abstract
From June 1987 to September 1990, 12 patients were evaluated for ureteroscopic treatment of upper urinary tract neoplasms. Four patients were not considered candidates because of technical reasons. Each of these patients was treated by nephroureterectomy. A total of 8 patients underwent ureteroscopic therapy with a neodymium:YAG laser 1 to 11 times (median 2) for the treatment of 3 proximal ureteral or pelvic lesions and 7 distal ureteral lesions. One patient had local progression and 1 failed subsequent laser treatment for technical reasons. Both of these individuals were salvaged with an operation. Three patients were without recurrence for 15, 21 and 36 months. Two patients had multiple superficial local recurrences and continue to be managed endoscopically without local progression for 12 and 32 months. One patient was asymptomatic 16 months after treatment but he has refused followup evaluation.Of 7 patients with ureteral tumors who were believed to be candidates for endoscopic therapy 5 have had the tumors controlled by this method of treatment. Only 1 renal pelvic tumor has been successfully treated. Most patients with tumors in the renal pelvis are not candidates for rigid endoscopic therapy because of the tumor size and location. In selected individuals ureteroscopic laser treatment of upper urinary tract transitional cell carcinoma can achieve local control with renal preservation.
