Perirenal hematoma extending to the ipsilateral scrotum region after shock wave lithotripsy treatment

Abstract

Perirenal hematoma after extracorporeal shock wave lithotripsy (ESWL) is an unusual but underdiagnosed complication. Most hematomas are asymptomatic, but severe complications are possible, which may require intervention such as a blood transfusion. We present the case of a 41-year-old Asian man suffering from a symptomatic huge perirenal/subcapsular hematoma with scrotal hematoma after ESWL; we reviewed the literature and examined the possible risk factors and treatments. This case was a very rare presentation of hematoma extension into the scrotum region from an ipsilateral perirenal hemorrhage caused by shock wave lithotripsy treatment.
