Is a single instillation sufficient?
PURPOSE: To evaluate the safety and efficacy of a single instillation in a combination of povidone iodine with contrast agent under fluoroscopy guidance for the treatment of chyluria. MATERIALS AND METHODS: From December 1999 to July 2006 a total of 40 patients with chyluria were treated by renal pelvic instillation therapy (RPIS). The sclerosing solution was prepared using povidone iodine with contrast agent diluted with sterile water in a ratio of 1:1:3. It was instilled on the side having chylous efflux using a bulb tip ureteric catheter. Unilateral instillation was done in 26 cases, 10 on the right side and 16 on left. Fourteen patients had bilateral chylous efflux and RPIS was performed on both sides in the same session. Fluoroscopy was used to evaluate the complete filling of the pelvic calyceal system. The sclerosing solution was kept in the system for 5 minutes and the ureteric catheter was then withdrawn. RESULTS: Immediate clearance was observed in 39 patients. Recurrence occ
