Abstract：Objective:To assess the technique and result of retroperitoneoscopic renal pedicle lymphatic disconnection for the treatment of patients with intractable chyluria. Methods:Fifteen cases of chylurian were selected for retroperitoneoscopic renal pedicle lymphatic disconnection. Patient demographics, perioperative data, follow-up and prognostic information were collected. Results:Fourteen cases were successful, except one case was changed to open operation due to extensive adhesion between renal vessels and associated lymphoid tissue. The operative time ranged from 48-200 minutes( mean 119 minutes), intraoperative blood loss was minimal(mean 67 ml), two cases accepted the blood transfusion of 2 u erythrocyte and 2u plasma. The mean time of postoperative intestinal function recovery were 1.8 days, postoperative complication was one case of subcutaneous emphysema, postoperative hospital stays were 3-9 days(mean 6.3 days). Chyluria disappeared in all patients without recurrence during a follow up of 4-112 months (mean 43 months). All patients gained weight and had greatly improvement in nutritional condition. Conclusions:Retroperitoneoscopic renal pedicle lymphatic disconnection for the treatment of chyluria is an effective and efficient surgical procedure and has the advantages of less blood loss, minimal invasion, complete lymphatic vessels ligation, short hospital stay and rapid recovery. So far, it is an ideal surgical procedure for treatment of chyluria.
