Between January 1986 and April 1988, 13 patients (mean age: 35 years) waiting for renal transplantation (mean duration of haemodialysis: 46 months) were treated by means of O'Donnell's technique. Vesico-ureteric reflux was unilateral in 6 patients and bilateral in 7 patients (20 refluxing ureteric units). Reflux was classified as Grade II for 7 ureters, Grade III for 8 ureters and Grade IV for 5 ureters. The volume of Teflon injected ranged from 1 to 4 cm3 and 6 patients received repeated injections. No complications were observed. Complete resolution of reflux was obtained in 9 patients (69%), i.e. 15 ureteric units (75%). Reflux persisted in 4 patients (31%), i.e. 5 ureteric units (25%). Three nephro-ureterectomies were performed in 2 patients with persistent high grade reflux, but 2 patients with Grade I reflux after endoscopic treatment were not operated. All patients were transplanted after endoscopic treatment (mean interval between correction of reflux and transplantation: 13 months) and a follow-up cystography was systematically performed after transplantation (mean follow-up after transplantation: 27 months): no recurrence of the reflux was detected (mean follow-up after endoscopic treatment: 40 months). Endoscopic treatment of reflux avoids the need for nephro-ureterectomy in 80% of haemodialysis patients waiting for renal transplantation and presenting with vesico-ureteric reflux.
