Recording of vesical voiding pressure by means of CO2-perfusion.Br J Urol. 1977 Nov; 49(6):531-5.BJ
By means of a CO-2-cystometer, carbon dioxide is introduced through a urethral catheter (F5) into the full urinary bladder while the subject is urinating around the catheter. A reproducible pressure curve can be recorded. The pressure values measured by CO2-perfusion correlate very well with those measured simultaneously by a conventional fluid method. It can be statistically demonstrated that the CO2 flowing into the bladder does not influence the vesical voiding pressure. It is concluded that the vesical pressure during micturition can be accurately recorded by CO2-perfusion.
