Summary
Indwelling double J ureteral stents are safe and effective for urinary drainage, with a minimal complication rate of 6.6% in 91 patients. These stents are useful for ureteral obstruction, surgery, and endourologic treatments.
Area of Science:
- Urology
- Medical Devices
Background:
- Indwelling double J ureteral stents are established in urologic literature for urinary drainage.
- Their application and outcomes require continued evaluation.
Purpose of the Study:
- To evaluate the safety and efficacy of double J ureteral stents in a patient cohort.
- To document indications, placement methods, complications, and drainage times.
Main Methods:
- A retrospective review of 91 patients who received indwelling double J ureteral stents.
- Majority of stents (68%) were placed endoscopically.
- Data collection included indications, complications, and drainage duration.
Main Results:
- Common indications included ureteral obstruction (39 cases), upper urinary tract surgery (29 cases), endourologic treatment adjunct (16 cases), and lithotripsy preparation (7 cases).
- The overall complication rate was minimal at 6.6%, with stent migration being the most frequent complication (3 cases).
- Average stent drainage time was 5.8 weeks.
Conclusions:
- Double J ureteral stents demonstrate a favorable safety profile with minimal complications.
- The study supports the use of double J stents as an effective option for various urologic conditions.
