Renal arteriovenous fistula (AVF) is a rare but potentially severe and life-threatening entity. It can occur after various invasive renal interventions, including resection of a localized renal tumor, renal biopsy, percutaneous renal surgery, and even blunt injury of the kidney. The time of clinical presentation of a renal AVF is variable and may occur decades after the injury originally occurred. Here, we report a case of renal AVF induced by extracorporeal shock wave lithotripsy 11 years earlier in an asymptomatic 72-year-old woman. Given the patient's pre-existing hemodialysis dependence, retroperitoneoscopic nephrectomy was performed. On the basis of patient's clinical history, the location of the renal AVF, and the pathological diagnosis, we suggested that renal AVF was a late consequence of the injury to the intrarenal vessels induced by extracorporeal shock wave lithotripsy.

In this case report the authors describe an arterio-venous fistula considered to be a late consequence of SWL. Treatment with SWL for removal of lower calyx stones had been carried out 11 (!) years earlier.
Arterio-venous fistula is a very unusual complication of SWL; rarely described in the literature and most certainly seldom encountered in the clinic.
It is likely that the patient’s arteriosclerosis and nephrosclerosis played a role in this process. End-stage renal insufficiency facilitated the therapeutic decision.
