Micturition Studies in Infants and Children: Technique

Abstract

A method for simultaneous and continuous registration of bladder pressure and urine flow is presented. It has been tested in infants and children of various ages. The sources of error and the reliability of the method are analysed. The pressure is measured via a suprapubic bladder puncture. The urine flow is converted into gas flow, which is registered by a pneumotachograph. The method is accurate enough for it to be used even in infants.
