Long-term results of endoureterotomy using a holmium laser.

Author information

Department of Urology, Kyoritsu General Hospital, Nagoya, Japan.


The long-term results of endoureterotomy using a holmium laser in cases of benign ureteral stricture, uretero-pelvic junction obstruction (UPJ-O) and ureteroenteric stricture were evaluated. Twenty procedures were carried out in 18 patients. Strictures were incised with a holmium laser using a fiber passed through the ureteroscope. Sixteen of the 20 procedures (80%) were successful at average follow-up of 60.5 months (range, 46-74). Stricture recurred in four cases. All failures occurred within 18 months. Although stricture length was not correlated with recurrence, all failures, with the exception of a single UPJ-O, involved middle ureteral strictures. Endoureterotomy using a holmium laser affords favorable results with respect to long-term patency. This procedure is recommended as a satisfactory therapeutic option for the initial management of patients presenting with ureteral stricture.
