Endoscopic treatment of ureterocele and antireflux injection with Teflon paste.

By referring to two cases, the author demonstrates the possibility of managing certain ureteroceles exclusively by endoscopic treatment. On one hand, by incising or resecting the ureterocele and, on the other hand, by suppressing the reflux thus created with a Teflon injection under the gaping ureterocele. The best indication for this method is the orthotopic ureterocele on a nondivided ureter, i.e. the ureterocele normally found in adults. It also seems possible to treat the orthotopic ureterocele on a duplex kidney in this way. On the contrary, the worst indications for this method are probably ectopic ureteroceles.
