Comparison of standard and ciné cystography for detecting vesicoureteral reflux

Variations in vesicoureteral reflux. Influence on diagnostic validity

Micturition cystourethrography was performed with varying numbers of films exposed and the probability of missing a vesicoureteral reflux or underrating its severity was calculated for each series. It was concluded that a small number of exposures can give sufficiently accurate diagnosis.

Conscious dynamic versus unconscious static cystourethrography

Prior to treatment 30 urologically symptomatic subjects were studied with dynamic voiding cystourethrography while conscious and with single shot high pressure static cystourethrography while anesthetized. The former technique did not surpass the latter in demonstrating reflux, lower urinary tract disease or urethral anatomical detail. It is concluded that (problem cases aside) when management requires anesthetizing the patient only the high pressure, single shot static method should be used and that omission of premedication and manipulation of anesthetic planes to produce voiding are neither necessary nor desirable.
