Objective:To summarize the experience of retroperitoneoscopic renal pedicle lymphatic disconnection in the management of chyluria

and to investigate a new minimally invasive treatment of chyluria. Methods:9 cases of chyluria were treated by retroperitoneoscopic renal pedicle lymphatic disconnection from Jan 2005 to Dec 2008 with 7 male ones and 2 female ones. The average age was 48 years. 8 of 9 cases obtained success and 1 of 9 cases was converted to open surgery. Operation time

blooding volume

postoperative complication and hospitalization stay

and the operative effect were observed. Results:The operation time was from 65 to 105 min

with the average of 70 min. The blooding volume was from 50 to 100ml

with the average of 60ml. Chyluria disappeared immediately after operation in all patients. Postoperative stay was from 5 to 7d and no complication happened. Conclusion:Retroperitoneoscopic renal pedicle lymphatic disconnection for chyluria is a effective and efficienl method in the management of chyluria. And it is also safe

minimally invasive

with less blood loss

fewer complications

and short hospital stay .
