[Damage to the renal peduncle vessels in extracorporeal lithotripsy].

The authors report a case of massive hemorrhage from the vessels of the renal peduncle in a 68-year-old male patient with nephroureterolithiasis after one session of ESWL. Urgent nephrectomy was made. Histologically, there were sclerotic-distrophic changes of the vascular peduncle of the left kidney induced by long-term obstruction of the ureter with the calculus and extravasation of the urine into the renal sinus. This ESWL complication may take place in elderly patients with long-term ureteral obstruction with the stone. In such cases ESWL should be carried out only in hospital.
