Step-by-step technique for the endoscopic treatment of ureteric stricture.

Abstract

To outline our step-by-step technique for the endoscopic treatment of ureteric stricture. Between January 2019 and June 2020, 25 patients with ureteric strictures underwent ureteric bypass and were included in this study. The ureteric bypass surgery included three key steps. First, holmium laser endoureterotomy was used to establish a small channel. Then, balloon dilatation was performed to create a large channel. Finally, an Allium stent was inserted. Over a median follow-up time of 12 months, the success rate of ureteric bypass surgery was 92.0% (23/25). The median operating time was 78 min. The incidence of pain was 16% (4/25), and the incidence of fever was 4.0% (1/25). The preoperative hydronephrosis volume and urea nitrogen levels decreased significantly after surgery. We performed ureteric bypass for patients with ureteric strictures. This technique was found to be safe and effective over a short follow-up time. For patients who are not suitable for surgical reconstruction, the ureteric bypass technique is a good choice.
