Abstract
The present study reported two cases in which selective artery embolization were identified to assist in resolving urinary fistulae following partial nephrectomies. The first case involved a 51‑year‑old male who received a mini‑incision partial nephrectomy with renorrhaphy. Following the operation, urine continued to discharge from the retroperitoneal drain. Selective renal artery embolization of the upper calyx at post‑operation day 20 was highly effective and urine output from the drain stopped immediately. Case 2 involved a 66‑year‑old male, who also suffered from a urinary fistula following a partial nephrectomy. Selective renal artery embolization performed at post-operation day 21 was again effective. In each case, the upper calyx was separated from the renal pelvis. These cases demonstrated that suturing of the collecting system and renal parenchyma may result in the separation of the urine pathway, and that selective renal artery embolization appears to be a highly effective treatment in such cases.
