Summary
Extracorporeal shock wave lithotripsy effectively treated bladder stones in 72% of patients, with no complications. This outpatient procedure offers a safe and efficient solution for bladder stone removal.
Area of Science:
- Urology
- Nephrology
- Medical Devices
Background:
- Bladder stones (vesical calculus) can cause significant lower urinary tract symptoms.
- Traditional surgical interventions for bladder stones carry risks of morbidity.
- Extracorporeal shock wave lithotripsy (ESWL) offers a non-invasive treatment option.
Purpose of the Study:
- To evaluate the initial efficacy and safety of extracorporeal shock wave lithotripsy for treating bladder stones.
- To assess treatment duration, fragmentation success, and complication rates.
Main Methods:
- 36 patients with bladder stones underwent extracorporeal shock wave lithotripsy.
- Treatment parameters included mean duration, number of shock waves, and electrical discharge.
- Outcomes assessed were stone fragmentation, evacuation, and patient morbidity.
Main Results:
- Successful minute fragmentation and uncomplicated evacuation were achieved in 26 patients (72%).
- Mean treatment duration was 55 minutes, with an average of 3600 shock waves at 24 kV.
- No intra-procedural or post-procedural morbidity was observed.
Conclusions:
- Extracorporeal shock wave lithotripsy is a safe and effective outpatient treatment for bladder stones.
- The procedure demonstrates high success rates for stone fragmentation and evacuation with minimal complications.
- ESWL represents a viable non-invasive alternative to surgery for vesical calculus.
