Operative technique for treatment of ureterocele of single ureter in children.

For treatment of simple ureterocele in children an operative technique is presented which is designed to eliminate the ureterocele and prevent future vesicoureteral reflux. This technique combines an intravesical with an extravesical approach to the distal ureter. The ureterocele is excised and the ureter reimplanted in the bladder at a different site. The exposure of the distal ureter allows tailoring to reduce its caliber, if needed, before reimplantation. During the last eight years 7 children with ureterocele of a single ureter have been treated with this technique. In each of the 7 children the objectives of the operation have been achieved, as proved by postoperative follow-up.
