Low transurethral incision of single system intravesical ureteroceles in children.

Single system intravesical ureteroceles in children usually result in various degrees of hydroureteronephrosis requiring surgical intervention to provide drainage, decompression and preservation of renal function. Our experience with 7 symptomatic single system ureteroceles in 5 children managed by low transverse endoscopic ureterocele incision is reviewed. After endoscopic incision, hydroureteronephrosis decreased in all patients. Vesicoureteral reflux after incision was noted in only 1 kidney. The technique of short (2 to 3 mm.) low transverse ureterocele incision is recommended for the initial management of single system ureteroceles to relieve obstruction. Preservation of the flap valve ureteral antireflux mechanism is possible in most children. The technique is simply performed, can be safely done in the youngest child and, in many, obviates the need for a further operation.
