Purpose: An obstructive megaureter identified in the neonatal period can be managed using a number of techniques, with the primary goal being to minimize the potential for further injury to the affected kidney. We describe our experience with refluxing ureteral reimplantation as a novel method for temporizing the obstructive megaureter. Materials and Methods: Three patients identified prenatally with severe hydroureteronephrosis were confirmed following delivery to have an obstructive ectopic ureter. Unilateral obstruction was identified in 2 patients (1 female, 1 male). The third patient was a female with bilateral single system ectopic ureters. Treatment consisted of anastomosing the ureter proximal to the obstruction to the dome of the bladder in a freely high grade refluxing fashion. All of the patients were placed on antibiotic suppression after surgery. Results: All patients demonstrated improved drainage of the affected kidney(s) following surgery. One female patient with unilateral obstruction had a poorly functioning kidney that showed no improvement of renal function 6 months following refluxing reimplantation, and laparoscopic nephrectomy was performed. The male patient with unilateral obstruction had adequate function with a significantly decreased ureteral diameter 1 year following refluxing ureteral reimplant, and a ureteral reimplantation without tapering was performed. The female patient with bilateral obstruction had 1 breakthrough urinary tract infection 6 months after surgery and now awaits second stage repair. Conclusions: Refluxing ureteral reimplantation is a safe, easy, beneficial and well tolerated means of temporizing the obstructive megaureter. This technique allows time for the child to mature, while accurately establishing renal function and preparing for a definitive surgical solution.
