The efficacy and safety of ureteral dilation and long-term type ureteral stent for patients with ureteral obstruction

摘要

Objective: This study was conducted to investigate the efficacy and safety of ureteral dilation and placement of a long-term ureteral stent for patients with various types of ureteral obstructions. Methods: We retrospectively reviewed the records of 39 patients presenting with ureteral obstruction secondary to malignant strictures (n = 9) or nonmalignant strictures (n = 30). The mean age of these patients was 55.8 ± 16.1 years (range, 13-87 years). All patients underwent retrograde ureteral balloon dilation and placement of one to three ureteral stents. Stent patency rate and complications including febrile urinary tract infection, stent encrustation, and stent fragmentation were recorded.
