Summary
Outpatient extracorporeal shock wave lithotripsy (ESWL) is a safe and effective treatment for upper urinary tract stones. This study found high stone-free rates with minimal complications, supporting its use in an outpatient setting.
Area of Science:
- Urology
- Nephrology
- Medical Technology
Context:
- Extracorporeal shock wave lithotripsy (ESWL) has become a primary treatment modality for upper urinary tract stones.
- The shift towards outpatient procedures necessitates evaluation of their efficacy and safety.
- This study focuses on the outcomes of ESWL performed in an outpatient setting.
Purpose:
- To evaluate the safety and efficacy of outpatient ESWL for treating upper urinary tract stones.
- To determine the stone-free rates and complication profile of outpatient ESWL.
- To assess the feasibility of treating a high volume of patients with upper urinary tract stones as outpatients.
Summary:
- 600 patients with upper urinary tract stones were treated with ESWL, with 78.6% managed as outpatients.
- The study evaluated the first 500 outpatient ESWL treatments, reporting an overall stone-free rate of 78.1% at 3 months.
- Complications were minor, primarily pain and fever, with no serious perioperative events.
- Average treatment involved 1.4 sessions and 6,988 shock waves, with 74% requiring only one session.
Impact:
- Outpatient ESWL is demonstrated to be a safe and efficient procedure for upper urinary tract stones.
- The findings support the continued use and expansion of outpatient ESWL services.
- This approach offers a convenient and effective treatment option with a low complication rate.
