Ureteric orifice deformation causing secondary reflux.
In two boys with posterior urethral valve and dilated ureters ureteroneocystostomy according to Politano-Leadbetter was performed at 4 and 6 months of age. Postoperatively both children showed vesicoureteric reflux. Endoscopic examination revealed in both cases a mucosal bridge between the medial borders of the ureteric orifices. The bridge was transected with transurethral endoscopic diathermy whereupon the reflux disappeared permanently. The fixation and deformation of the orifices were probably part of the mechanism causing the reflux. Endoscopy is recommended in case of postoperative reflux.
