CLINICAL STUDIES ABOUT THE DISTURBANCE OF MICTURITION

I. Comparative Studies Between Water-Cystometry and CO₂ Cystometry

Abstract

CO₂ cystometer (DISA 21G45 cystograph) was used in 153 patients for about one year and 6 months. 23 patients of them was compared with the results obtained with fill water cystometry and rapid fill CO₂ cystometry. In 21 patients the cystometric pattern was the same for both methods. In 2 patients we found uninhibited contraction with watercystometrogram but not with CO₂ cystometrogram. The medium volume at first desire to void was larger in watercystometrogram than in CO₂ cystometry in the normal type of the bladder, but in cases of the spastic type the volume was almost the same for both methods. Bladder volume was larger in watercystometry than in CO₂ cystometry in the normal and flaccid types, but in cases of the spastic type the volume was the same. We concluded that the CO₂ cystometry was safer, simpler and more time-saving than watercystometry.
