Cystometry in Normal Korean Males: Preliminary Report

  • 1Department of Urology, Seoul National University College of Medicine, Seoul, Korea.


Cystometry was performed on 34 adult, healthy Korean males and the results were compared with those by various investigators. Retrograde intermittent, cystometry, retrograde continuous cystometry and excretory cystometry were used for this purpose. The instrument used was a simple water cystometer which has been used in our clinic. Effects of concentration and temperature of the fluids on the pressure of the bladder were also studied. Sterile water, normal saline, 5% saline, 10% saline and 20% saline in room temperature were administered for "the concentration study" and sterile water in 37C(degree), 38C, 39C, 40C, 41C, 45C, 35C, 30C, 25C, 23C, 22C, 21C, 20C and 10C were used respectively for "the temperature study". The results of both retrograde intermittent cystometry and retrograde continuous cystometry agreed well and there was no significant difference. In this study the first voiding desire starts at approximately 200-400 cc of fluid and the maximum voiding desire at approximately 350-450 cc of fluid The average pressure of the bladder ranges between 4.0-12.0 cm H20, the pressure at the first voiding desire is approximately 9.7 cm H2O and the pressure at maximum voluntary pressure over 32-130 cm H2O. No significant change in the pressure occurred due to changes in concentrations of the fluid but the maximum bladder capacity decreased as higher and lower concentrations of the fluid were administered. Also, higher and lower temperatures of the fluid did not cause significant changes in the pressure but the maximum bladder capacity decreased slightly.
