Correction of vesicoureteral reflux by intravesical injection of collagen in a canine model.
A reflux model was created in 12 dogs to test the application of subureteric injection of collagen as a biodegradable substitute for ureteroneocytostomy. The injection technique was initially successful in 64% of dogs. Failure was related to deficiency in intramural tunnel and was unrelated to bladder function. Cystograms in 4 successfully corrected survivors showed resumption of reflux, although postmortem histology showed persistence of the collagen implant at the injection sites.
