Value of endoscopic incisions in the treatment of ureteroceles in children

Endoscopic incision is a simple method to provide decompression of the urinary tract above ureteroceles. This technique has been used in most cases of ureterocele seen since 1987. In 6 cases of ureterocele in a single system good results were achieved in all cases. In 13 cases of ureterocele in a duplex system, incision was the only procedure in 5 patients. Seven patients required further surgery : upper pole partial nephrectomy when dilatation persisted, ureteral reimplantation and ureterocele excision in cases of upper pole reflux, secondary to the endoscopic incision, or in cases of persistent reflux in the lower pole ureter. Endoscopic incision is a safe treatment in cases of intravesical ureterocele (single system or duplex system) but in the cases of ectopic ureteroceles, it generally provides only temporary benefit. In these cases, it facilitates delayed lower urinary tract surgery.
