Summary
Extracorporeal shock wave lithotripsy (ESWL) effectively fragments bladder stones, with most patients needing one session. Pre-TURP ESWL can reduce complications and operating time for bladder stone treatment.
Area of Science:
- Urology
- Nephrology
- Medical Devices
Background:
- Bladder stones pose a significant clinical challenge.
- Traditional treatments for bladder stones can be invasive.
Purpose of the Study:
- To evaluate the efficacy and outcomes of extracorporeal shock wave lithotripsy (ESWL) for treating bladder stones.
- To assess the impact of ESWL on subsequent procedures like transurethral resection of the prostate (TURP).
Main Methods:
- Utilized the MPL 9000 extracorporeal shock wave lithotriptor with ultrasound localization for 29 patients with bladder stones.
- Analyzed stone dimensions, number of ESWL sessions, and fragmentation success.
- Observed outcomes in patients undergoing TURP after ESWL.
Main Results:
- Satisfactory fragmentation was achieved in all patients.
- 75% of patients required only one ESWL session; larger stones generally needed more sessions, but size was not the sole determinant.
- ESWL prior to TURP reduced morbidity and operating time, with ESWL fragments being manageable during TURP.
Conclusions:
- ESWL is an effective treatment for bladder stones, offering high fragmentation rates and often requiring a single session.
- Performing ESWL before TURP can streamline the management of bladder stones, particularly in cases with prostatic obstruction, by reducing overall procedural burden.
