Summary
Peripelvic extravasation, a rare complication of extracorporeal shock wave lithotripsy (ESWL), can cause flank pain. Treatment with a double-J catheter effectively reduced pressure and resolved the extravasation.
Area of Science:
- Urology
- Nephrology
- Medical Imaging
Background:
- Extracorporeal shock wave lithotripsy (ESWL) is a common procedure for kidney stones.
- Complications, though rare, require careful management and understanding.
- Peripelvic extravasation is an uncommon but significant adverse event following ESWL.
Observation:
- A 62-year-old male presented with macroscopic hematuria and was treated for a right kidney stone using ESWL.
- Two weeks post-ESWL, the patient developed right flank pain.
- Drip infusion pyelography (DIP) and computerized tomography (CT) revealed peripelvic extravasation of contrast medium.
Findings:
- Placement of a double-J catheter successfully decreased intra-pelvic pressure.
- The peripelvic extravasation resolved following the intervention, as confirmed by DIP and CT.
- A review of Japanese literature identified four additional cases, including this one, of peripelvic extravasation post-ESWL.
Implications:
- This case highlights peripelvic extravasation as a potential complication of ESWL.
- Double-J catheterization appears to be an effective treatment for managing this complication.
- Further research into the causes and prevention of peripelvic extravasation after ESWL is warranted.
