title: Endoscopic correction of vesico-ureteric reflux in duplex systems.
abstract: Between May 1984 and April 1990, 37 children with vesico-ureteric reflux (VUR) in 43 duplex systems were treated by endoscopic subureteric Teflon injection (STING). There were 32 girls and 5 boys; the duplex systems were complete in 27 refluxing units and incomplete in 16 refluxing units. All patients had high-grade reflux. In incomplete duplicated systems, VUR was corrected in 14 (87.5%) after a single injection of polytef paste and 2 patients required 2 injections to correct VUR. Of the 27 refluxing units with complete ureteral duplication, reflux was corrected in 16 (59%) units after a single injection of polytef paste, and 3 (11%) units showed improvement of VUR to grade I or II after 1 injection; no further treatment was given. 7 units with complete ureteral duplication required 2-4 injections for correction of VUR. STING failed to correct VUR in 1 duplex system which required a re-implantation. In 93% of refluxing units where VUR was corrected by a single injection, the quantity of polytef paste used was less than 0.3 ml. 36 (97%) of patients were discharged home on the day of the procedure. All patients were followed up for 2-8 years. Of the corrected ureters, there were no recurrences in the incomplete duplicated ureters. 3 of the completely duplicated ureters showed recurrence of reflux at follow-up micturating cystography.(ABSTRACT TRUNCATED AT 250 WORDS)
