Laparoscopic stenting is a simple technique that obviates the need for an additional procedure and decreases the risk of the stent being cut or migrating upward. It also provides better anatomical delineation and dissection around the ureteropelvic junction since the pelvis remains distended. In addition, it makes suture placement and knot tying easy.

or 'recurrence' of chyluria were treated with second course of RPIS using same sclerosant. RESULTSThe dextrose treatment was discontinued at mid-term because of poor success (one of 21 patients, P < 0.001). Of 85 patients, 44 received silver nitrate and 41 povidone iodine; both groups were well-matched and the mean follow-up was 28.4 and 23.3 months, respectively. 'Immediate clearance' was recorded in 91% and 98%, and recurrence in 21% and 22% of patients after the first course of RPIS, after silver nitrate and povidone, respectively; Kaplan-Meier estimates of 'disease-free duration' in the two groups (23.6 vs 20.1 months) were also similar ( P = 0.7906). The cumulative success rate after two courses of RPIS was 82% (silver nitrate) and 83% (povidone; P = 1.0). Five (11%) patients in the silver nitrate and one (2%) in the povidone group had significant flank pain during treatment. CONCLUSIONSPovidone iodine 0.2% is as effective for RPIS as 1% silver nitrate.
