EnglishVascular complications secondary to surgical treatment of localized kidney cancer are more frequent when a nephron-sparing surgery is performed. However, radical nephrectomy is not exempt from them. We report the case of a pseudoaneurysm of the main renal artery with fistulous communication to ascending colon after radical nephrectomy. The patient presented with an episode of hypovolemic shock due to lower gastrointestinal bleeding.

Bladder diverticula are herniations of the mucosa through the fibers of the bladder muscle connected by necks of variable amplitude. They are often asymptomatic, although they may lead to complications that require a surgical therapeutic approach. We report the case of a patient with bilateral obstructive uropathy secondary to a giant periureteral diverticulum that was treated by diverticulectomy and reimplantation of the left ureter in the bladder.
