Postoperative ureteral leak treated using a silicone-covered nitinol stent

Area of Science:

• Urology
• Surgical Complications
• Medical Device Technology

Background:

• Ureteral fistula is a severe complication following abdomino-pelvic surgeries.
• Existing treatments for ureteral fistula often yield suboptimal outcomes.
• Effective management strategies for post-surgical ureteral leakage are critical.

Purpose of the Study:

• To evaluate the efficacy and safety of a silicone-covered ureteral occlusion stent.
• To present a case study on managing ureteral leakage post-pelvic surgery.
• To propose this stent as a practical solution for ureteral fistula.

Main Methods:

• A 49-year-old female patient with ureteral leakage post-pelvic surgery was treated.
• A silicone-covered ureteral occlusion stent was placed in the right ureter.
• Follow-up ureterogram was performed 18 months post-stent placement.

Main Results:

• The silicone-covered ureteral occlusion stent effectively managed the ureteral leakage.
• No stent migration was observed during the 18-month follow-up.
• No additional urine leakage was detected post-procedure.

Conclusions:

• The silicone-covered ureteral occlusion stent is a practical and safe option for managing ureteral leakage.
• This method provides a fast and effective treatment for ureteral fistula.
• The stent demonstrates long-term efficacy in preventing urine leakage.
