Some investigations have indicated that in patients with chyluria, part of the uptake fat and protein leaks from the urine.Thus, recurrent chyluria may result in malnutrition. In addition, with nearly one half of the body＇s the urine, depressed regulatory lymphocytes lost through functions of the lymphatic system may cause illnesses following immune deficiency. Therefore, it is imperative to provide effective and active medical care for chyluria patients. The purpose of surgical treatment is to eliminate lymphatic fistula and decrease intralymphatic pressure. We recently performed retroperitoneoscopic renal pedical lymphatic disconnection for 78 cases of chyluria patients in our hospital between April 2003 and June 2007. We herein summarize our experience as follows.展开更多

Since its introduction in 1995, laparoscopic living donor nephrectomy has been shown to decrease postoperative pain and hospital stay, reduce blood loss, and improve cosmesis while hastening recovery of normal activities of donors. With decreased morbidity and favorable graft function, this procedure as a novel approach has been used to address the increasing disparity between organ need and availability. Better graft function and survival are noted in living-donor kidney transplantation than in cadavefic kidney transplantation.展开更多
