Self-retained internal ureteral stents: a new approach

Area of Science:

• Urology
• Minimally Invasive Surgery

Background:

• Definitive surgical treatment for ureteral obstruction is often unsuitable for patients with advanced malignancy, complex benign conditions, or high operative risks.
• Endoscopic placement of internal ureteral stents offers a viable alternative for symptom relief.

Purpose of the Study:

• To describe a new 6F pigtail ureteral stent and its placement technique.
• To evaluate the efficacy and tolerability of this new stent for short-term drainage in ureteral obstruction.

Main Methods:

• Endoscopic placement of a novel 6F pigtail ureteral stent.
• Evaluation of placement ease, effectiveness, and patient tolerance for short-term urinary drainage.

Main Results:

• The new 6F pigtail ureteral stent was easily placed.
• The stent provided effective and well-tolerated short-term drainage for selected patients.
• This approach offers satisfactory relief for patients with ureteral obstruction unsuitable for surgery.

Conclusions:

• The described 6F pigtail ureteral stent and technique are suitable for short-term management of ureteral obstruction.
• This endoscopic approach provides an effective and well-tolerated option for high-risk patients.
