Application of Urethral Pressure Profile in Patients with Benign Prostates Hypertrophy / 中国康复理论与实践

@#Objective To apply the urethral pressure profile(UPP)in patients with benign prostates hypertrophy(BPH).Methods 71 patients with BPH accepted the test of UPP.The UPP parameters were compared statistically with the ultrasonography finding.Results The maximum urethral pressure,maximum urethral closure pressure and prostatic urethral length in BPH were higher than normal(P<0.01).Conclusion The test of urethral pressure profile(UPP)is helpful for identifying the site of obstruction and degrees in BPH patients,although there are some limits.

Characteristic Changes of Cough Urethral Pressure Profile in Stress Urinary Incontinence / 대한비뇨기과학회지

Urodynamic study developed because physicians recognized that history, physical examination and previous testing modality were inadequate to differentiate between those patients with and those without stress urinary incontinence( SUI). The purpose of this study is to evaluate the practicability and usefulness of the test cough urethral pressure profiler in the evaluation of SUI with objective data. Between November 1991 and October 1993, 45 patients with symptoms of urinary incontinence were studied to determine the value of this test by using microtip transducers of Urocompact 8000 which is a computerized urodynamic system. Dynamic pressure profiles were obtained during cough by measuring the pressure at the proximal, middle and distal urethra. At rest, functional urethral length and maximal urethral closure pressure were 3.01+/-0.58cm, 52.0+/-17.8cmH2O respectively (control 3.66+/-0.35cm, 80.25+/-16.95cmH2Orespectively, p <0.05, p<0.05). During the cough, urethral closure pressure decreased to negative pressure in 41 of 42(98% ) patients who were available for analysis. Three of the 45 patients were not available due to the lack of experience of one. Six months after bladder neck suspension was performed, the urethral pressure profile of four patients were checked again and the results showed that the functional urethral length and maximal urethral closure pressure at rest were greater than those of the preoperative urethral pressure profile, but statistically not significant. In 3 patients who underwent successful treatment, the urethral closure pressure at cough did not decrease to a negative pressure. As a result, the cough urethral pressure profile is a useful and objective diagnostic method of SUI and evaluation of the postoperative state.

The Value of Urethral Pressure Profile and Urine Flow Rate Measurement in the Preoperative assessment for Benign Prostatic Hypertrophy / 대한비뇨기과학회지

Diagnostic urethral Pressure profile and uroflowmetry were performed on 10 cases and 3 cases respectively in benign enlargement of prostates who were admitted to Seoul National University Hospital, during the period from March, 1980 to July, 1980. The results of these studies were summarized as follows; 1. On 10 cases, mean endoscopic prostatic urethral length and mean functional urethral length (prostatic urethral length) in urethral pressure profile were 4.3cm and 4.8cm respectively, mean maximum urethral closing pressure was 70cm H20. These findings revealed that mean maximum urethral closing pressure was lower than normal value, mean functional urethral length was no difference from the normal value. (4.3 to 5.5cm) 2. On 3 cases, the results of uroflowmetry obtained as follows: mean maximum flow rate 11ml/sec, mean flow rate 7.0 ml/sec. 2 cases checked residual urine, 200ml and 70ml. 3. On 2 cases, the cystometric findings showed low value of first voiding sense (70ml and 60ml) and maximum bladder capacity (100ml and 80ml). It indicated the unstable bladder pattern which accompanied occasionally in benign enlargement of prostate. 4. The acceptance and adoption of urethral pressure profile and uroflowmetry in benign enlargement of prostate greatly facilitated understanding of urethral physiology and diagnostic accuracy in addition to rectal examination, excretory urography and endoscopy.

Clinical Observation of Normal Uroflowmetry and Urethral Pressure Profilometry / 대한비뇨기과학회지

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.).
