Objective:
To describe the results and follow-up of 34 vesico-ureteral reimplantations in infants.
Methods:
From 1985 to 1994, 34 vesico-ureteral reimplantations (Cohen transtrigonal technique) were performed in 20 infants aged 1-13 months. The indications for surgery were high grade congenital vesico-ureteral reflux and breakthrough pyelonephritis that had presented in some cases despite prophylactic measures.
Results:
At 4 years mean follow-up, all reimplanted ureters showed no reflux. One case with bilateral reimplantation was lost to follow-up.
Conclusions:
Many of the infants with vesico-ureteral reflux can be managed medically and the reflux will cease in some cases. But a few of them with difficult to control infections, can benefit from early surgery.
