Correlation of the endoscopic appearance with clinical outcome for submucous Polytef paste injection in...

The endoscopic injection of Polytef paste is now a well established method of treating vesico-ureteric reflux. In this study the video tapes of 64 treatments were independently reviewed to assess any predictors of failure. The visual appearance of the mound of paste was found to correlate with the clinical outcome, except when less than 0.2 mL of paste was used for smaller ureteric orifices, or when the ureteric orifice was large enough to admit the 9.3 FG cystoscope. In cases with a large ureteric orifice effective treatment was achieved without the neat crescent-on-a-mound appearance, provided a larger than average volume of paste was used. Meticulous placement of the needle was also shown to be important if success was to be ensured.
