A 87-year-old man received radical nephroureterectomy for right renal pelvic cancer in 2009 and left cutaneous ureterostomy after radical cystectomy for bladder cancer in 2013. He visited the hospital for exchanging a 7 or 8 Fr single-J catheter every 2 to 4 weeks. Eleven months after the 2nd operation, massive bleeding from the stoma occurred when ureteral catheter was exchanged. Contrast-enhanced computed tomography showed that left inferior epigastric artery was located close to left ureter. Angiography of the left inferior epigastric artery didn't show an obvious fistula, but revealed the stoma was surrounded by ramified new blood vessels from left inferior epigastric artery. We suspected a rupture of the vessels and performed embolization for the branch of inferior epigastric artery to left ureter. This embolization made it possible for the bleeding to be controlled. Massive bleeding from the branch of inferior epigastric artery is very rare, and we report the case and review the literature.

Objective: We examined laparoendoscopic single-site surgery (LESS) for urachal remnants and evaluated its usefulness and efficacy., Patients and Methods: From August 2011 to July 2012, we underwent this surgery for 5 patients (3 males, 2 females). The mean age was 30.8 (25-36) years old. A 2 cm incision was made around the umbilicus and Access Platform was placed. The entire urachal tissues were excised, and this 2 cm incison was reshaped as the umbilicus., Results: The median operative time was 220 (156-460) minutes, and the median operative blood loss was 10 (10-70) ml. They had no operative complications, and were discharged 6 (5-14) days after surgery., Conclusions: Our surgical procedures have very excellent cosmesis and advantages in particular for young because we reshape as the umbilicus the surgical wound. We think that this surgery can be performed safe and effectively for surgeons trained in the conventional laparoscopic procedures.

A 51 year-old man admitted to our hospital for macroscopic hematuria and right abdominal mass. CT demonstrated a large hypervascular mass and tumor thrombus in the inferior vena cava and right atrium. We diagnosed right renal cancer (stage III), and he underwent radical nephrectomy and resection of tumor thrombus with extracorporeal circulation. Operative time was 9 hours. Time for extracorporeal circulation was 119 minutes, and it took 60 minutes for intraoperative balloon occlusion of descending aorta in order to arrest hemorrhage. Pathological diagnosis was clear cell carcinoma of the kidney (pT3c, N0, M0). Four days after surgery, paraplegia was evident, and a diagnosis of spinal cord infarction was made based on neurologic examination and MRI findings. In cases with such a surgery requiring extracorporeal circulation, preoperative meeting with cardiologists and anesthetists is indispensable in order to fully understand the possible complications. Especially, to keep a careful watch and prepare for spinal cord ischemia is mandatory.
