Summary
J-stents effectively ensure free urinary drainage and prevent leakage in 200 patients. These ureteral stents significantly enhance extracorporeal shock wave lithotripsy (ESWL) outcomes with minimal complications.
Area of Science:
- Urology
- Medical Devices
- Nephrology
Background:
- Ureteral obstruction and urine leakage are significant clinical challenges.
- J-stents offer a solution for maintaining urinary tract patency.
- Their role in conjunction with extracorporeal shock wave lithotripsy (ESWL) requires evaluation.
Purpose of the Study:
- To evaluate the efficacy and safety of J-stents in various urological procedures.
- To assess the role of J-stents in preventing ureteral obstruction during ESWL.
- To document complications associated with J-stent placement and removal.
Main Methods:
- Retrospective analysis of 200 patients treated with J-stents.
- J-stents were placed endoscopically under local anesthesia in most cases.
- Indications included prevention of obstruction before ESWL, bypassing obstruction, and adjunct to surgery.
Main Results:
- All 200 cases demonstrated successful free drainage.
- No mortality was associated with J-stent use.
- Complications included encrustation (10.5%) and migration (5.5%), with easy removal under local anesthesia.
Conclusions:
- J-stents are effective in providing free urinary drainage and reducing complications.
- They enhance the effectiveness of ESWL therapy.
- J-stents represent a safe and valuable tool in urological practice.
