Hyperammonaemic encephalopathy after a subureteric injection for vesicoureteric reflux.

Correction of experimentally produced vesicoureteric reflux in the piglet by intravesical injection of Teflon.

Vesicoureteric reflux was produced in eight piglets by opening their bladders and slitting the anterior intravesical wall of the ureter. Cystography confirmed the presence of bilateral reflux in six piglets and unilateral reflux in two. Six to eight weeks later the bladder was again opened and Teflon paste injected in the space behind the intravesical ureter, thereby creating a support for the ...

Endoscopic correction of primary vesicoureteric reflux: results in 94 ureters.

Sixty one patients with primary vesicoureteric reflux were treated by endoscopic injection of Mentor Polytef paste. Seventy six of the 94 treated ureters showed complete disappearance of vesicoureteric reflux after one injection. Eight refluxing ureters required a second injection, one required a third, and one a fourth. Six ureters showed improvement in the grade of reflux after the first inje...

Endoscopic Teflon injection for a refluxing ureteric stump after simple nephrectomy.

A 43 year old man underwent right simple nephrectomy for a chronically infected non-functioning kidney containing a large staghorn calculus. At operation the right ureter was found unexpectedly to be grossly dilated and was ligated with catgut. As a result of limited surgical access in an obese patient this ligature slipped off during application and the ureter could not be retrieved for religa...

Treatment of vesicoureteric reflux by endoscopic injection of Teflon. 1984.

Thirteen girls with grade III-V vesicoureteric reflux were treated by endoscopic injection of Teflon paste behind the intravesical ureter. Fourteen of the 18 treated ureters showed complete absence of reflux after one injection of Teflon. Three ureters required a second injection of Teflon for successful treatment of the reflux. One ureter with grade IV reflux was converted to grade II reflux. ...
