Clinical Observation of Normal Uroflowmetry and Urethral Pressure Profilometry

Choi, Kyung Jin; Kim, Young Kyoon

Abstract

Uroflowmetry and Urethral Pressure Profilometry were made on 4 cases and 6 cases respectively who visited our Department of Urology during the period of March 1980 to July 1980. The results were summarized as follows; 1. On 2 women cases, uroflowmetry with anal sphincter electromyography revealed: Maximum flow rate; 30ml/sec, voided volume: 500ml-750ml. Time to Maximum flow rate; 4.8 sec~10.8 sec. Voiding time; 40 sec~84 sec., average flow rate; 5.9ml/sec~18.7ml/sec., residual urine ;0 Detrusor-sphincter dyssynergia did not appear. 2. On 2 men cases, uroflowmetry with anal sphincter EMG revealed: M.F.R.; 25ml/sec., V.V.: 500ml, Time to MFR; 1.7 sec.~6 sec. V.T. 43.2 sec.~48 sec., A.F. R.; 10.4ml/sec.~11.6ml/sec. R.U.; 0. Detrusor-sphincter dyssynergia did not appear. 3. On 2 women cases, urethral pressure profilometry with EMG revealed: Functional profile length; 2.8cm~3cm. Maximum urethral closure pressure ; 50cmH2O~80cmH20. Maximum urethral pressure; 70cmH2O~90cm H2O The maximum EMG sensitivity appeared on the midurethra. 4. On 4 men cases, urethral pressure profilometry with EMG revealed: F.P.L. ; 4.5cm~6cm, M.U.C.P.; 60cm 11,0~140cm H.O. M.U.P. 80cmH2O~160cm H20. Prostatic length: 2.5cm~3.8cm. The maximum EMG sensitivity appeared on the external sphincter. 5. We concluded that urodynamic study was the important method to diagnose the lower urinary tact lesions in addition to previous method (excretory urography, cystoscopy, panendoscopy etc.).
