Abstract

Partial nephrectomy is widely accepted as a treatment for small renal cell carcinoma. However, the laparoscopic approach has not yet been considered as a standard procedure. We reviewed our 13 retroperitoneoscopic partial nephrectomies and 11 conventional open partial nephrectomies. We have used microwave tissue coagulation for retroperitoneoscopic surgery without renal pedicle clamping between December 1999 and May 2003. The mean operating time for the retroperitoneoscopic group was not significantly longer than that for conventional open surgery group (183 minutes vs 194 minutes). However, the mean blood loss for the retroperitoneoscopic group was less than that for the open group (143 ml vs 512 ml). Histologic evaluation revealed renal cell carcinoma in 10 patients, angiomyolipoma in 2 patients, and lymphoangiomyomatosis in one patient for retroperitoneoscopic group and renal cell carcinoma in 11 patients for the conventional open surgery group. In addition, when compared with the historical control that had undergone conventional partial nephrectomy, laparoscopic cases had significantly shorter postoperative times to oral intake, ambulance, and discharge from hospital. Bowel injury, massive bleeding, urine leakage, and atel...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
