Summary
Extracorporeal shock wave lithotripsy (ESWL) for urinary stones required percutaneous nephrostomies in 5-50% of cases. Staghorn calculus treatment necessitates close collaboration between uroradiologists and urologists.
Area of Science:
- Urology
- Radiology
- Nephrology
Background:
- Urinary calculi (kidney stones) are a common ailment.
- Extracorporeal shock wave lithotripsy (ESWL) is a primary treatment modality.
- Management of complex stones, like staghorn calculi, presents challenges.
Purpose of the Study:
- To summarize the uroradiological experience with ESWL for over 1,500 urinary calculi.
- To evaluate the necessity and utility of percutaneous nephrostomies in ESWL procedures.
- To highlight the importance of multidisciplinary collaboration in treating complex urinary stones.
Main Methods:
- Review of uroradiological data from over 1,500 ESWL treatments.
- Analysis of percutaneous nephrostomy rates and subsequent use of tracts.
- Case review focusing on staghorn calculus management.
Main Results:
- Percutaneous nephrostomies were required in 5-50% of ESWL patients, varying with stone size and location.
- Over 25% of percutaneous nephrostomy tracts were utilized for additional procedures.
- Successful ESWL for staghorn calculi depended on integrated uroradiologist and urologist efforts.
Conclusions:
- ESWL is an effective treatment for urinary calculi, but may require adjunctive percutaneous nephrostomy.
- Percutaneous nephrostomy tracts offer a valuable access route for subsequent interventions.
- Multidisciplinary teamwork is crucial for optimal outcomes in complex staghorn calculus ESWL.
