ABSTRACT

Purpose: To present our initial experience with direct nipple ureteral reimplantation in infants with primary obstructed megaureter and an evaluation of two anti-reflux techniques.
Methods: We reviewed patients who underwent ureteral nipple valve reimplantation from 2/2010 to 6/2018. We included all patients who presented with obstructed megaureter required surgical intervention, age less than 12 months. Indications for surgical intervention were urinary infection and or split renal function less than 40%. The result is evaluated 6 months postoperatively. We compared two techniques: nipple length 10-15 mm versus nipple length 20 mm.
Results: The follow-up time was from 12 months to 102 months. There were 4 girls and 16 boys with 19 ureters of unilateral kidneys, two ureters of a bilateral system. The mean age at the time of surgery was 5.3 months (2.0 to 8.0 months). The first six ureters had the nipple length from 10 to 15 mm. The last 15 ureters had the nipple length of 20 mm. Six ureters with nipple length from 10 mm to 15 mm demonstrated vesicoureteral reflux, while 15 others with the 20 mm nipple length did not have reflux. No postoperative obstruction was found.
Conclusion: Direct nipple valve ureteral reimplantation is feasible in infants. The nipple length must be 20 mm to prevent vesicoureteral reflux.
