"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."
