[Early results of endoscopic treatment of vesico-ureteral reflux in children]. / Frühergebnisse der endoskopischen Behandlung des vesikoureteralen Refluxes bei Kindern.

Endoscopic treatment of vesicoureteral reflux (VUR) is based on transurethral injection of Teflon paste or collagen gel into the submucosa of the bladder wall beneath the distal ureter, resulting in support of the intramural part. This endoscopic procedure was performed in 75 children with VUR of varying severity. Altogether 111 ureters were treated, 94 with injections of Teflon paste and 17 with collagen gel. Improvement of VUR in the early postoperative period was achieved in 91.5% of the ureters treated with Teflon and in 82.4% of the ureters treated with collagen. No complications were observed. Endoscopic treatment of VUR seems to be an worthwhile alternative to open surgery. However, since long-term follow-up has not been completed, the efficacy of the method cannot yet be finally assessed.
