A New Self-expanding, Large-caliber Ureteral Stent Applied for Bilateral Long-segment Ureteral Strictures — A Case Report

Abstract

Urologists are experiencing difficulties managing ureteral strictures (US). Several treatment options have been used to treat US. Here, we present two patients with US. The first case is a 49-year-old woman with a history of squamous cell carcinoma of the cervix, status postlaparoscopy-assisted vaginal hysterectomy and radical parametrectomy, and bilateral pelvic lymph node dissection with recurrence. She regularly underwent double-J catheterization for bilateral US. The second case is a 66-year-old woman with a history of serious papillary adenocarcinoma of the endometrium, poststaging laparotomy with extrafascial hysterectomy + bilateral salpingo-oophorectomy + bilateral pelvic, common iliac, and para-aortic lymph node dissection + omentectomy. She regularly underwent double-J catheterization because of bilateral US. Allium stents have been used to treat US. Hydronephrosis improved in both patients. Renal function improved in one patient. A new self-expanding, large-caliber ureteral stent is another treatment option for patients requiring internal ureteral drainage.
