Summary
Subcapsular kidney hematoma (SH) after extracorporeal shock wave lithotripsy (ESWL) is rare (0.22%). Lumbar pain and falling hemoglobin are key risk factors, necessitating conservative management and ultrasound follow-up.
Area of Science:
- Nephrology
- Urology
- Radiology
Context:
- Extracorporeal shock wave lithotripsy (ESWL) is a common procedure for kidney stone treatment.
- Subcapsular kidney hematoma (SH) is a potential complication of ESWL.
- Understanding the incidence, risk factors, and management of SH is crucial for patient safety.
Purpose:
- To analyze the incidence of subcapsular kidney hematoma (SH) following ESWL.
- To evaluate the management strategies for SH.
- To identify patient- and ESWL-related risk factors for SH development.
Summary:
- A retrospective analysis of 2250 ESWL sessions identified 5 cases of SH (0.22% incidence).
- SH was diagnosed via ultrasound (US), with 80% of patients experiencing lumbar pain and decreased hemoglobin.
- Conservative management with US follow-up led to near-complete resolution within six months without sequelae.
Impact:
- Identifies sustained lumbar pain and hemoglobin drop as significant risk factors for SH post-ESWL.
- Recommends conservative management and US monitoring for SH unless complications arise.
- Highlights the low incidence of SH and the effectiveness of conservative treatment strategies.
