Summary
Extracorporeal shock wave lithotripsy (ESWL) can cause early complications. A patient developed a psoas abscess after ESWL for a solitary kidney stone, requiring surgical drainage.
Area of Science:
- Nephrology
- Urology
- Surgical Complications
Background:
- Extracorporeal shock wave lithotripsy (ESWL) is a common procedure for kidney stones.
- Previous studies noted transient renal effects post-ESWL, typically resolving within 2-3 months.
- Complications, though infrequent, require careful monitoring.
Observation:
- A patient with a solitary renal calculus underwent ESWL.
- The patient presented with early signs of complication including psoas spasm.
- Clinical indicators of infection, such as elevated white cell count and erythrocyte sedimentation rate, were observed.
Findings:
- A psoas abscess was diagnosed, extending from the renal hilum to the groin.
- This represented an early and significant complication of ESWL.
- The psoas abscess necessitated surgical intervention and drainage.
Implications:
- Highlights the risk of early, severe complications following ESWL, even in solitary stone cases.
- Emphasizes the need for vigilant post-procedure monitoring for signs of infection or abscess formation.
- Suggests a potential need to re-evaluate ESWL protocols or patient selection criteria for solitary renal calculi.
