Abstract

Diagnostic values and limitation of conventional urodynamic study (UDS) were assessed in 380 patients with benign prostatic hypertrophy (BPH), in terms of uroflowmetry, measurement of postvoid residual urine and cystometry. Maximum and average flow rate on uroflowmetry improved with increasing voided volume. Neither maximum nor average flow rate correlated with size of the prostate, subjective symptom (International Prostate Symptom Score) and bothersomeness for prostatism. Pre-TUR maximum flow rate did not predict outcomes on postoperative flow rate and surgical treatment failures. Uroflowmetry did not differentiate between obstruction and weakness of detrusor contraction. The intraindividual variation of postvoid residual urine was great and the volume of residual urine correlated poorly with subjective symptom, size of the prostate, maximum and average flow rate. On filling cystometry, although uninhibited detrusor contraction was much more frequently observed in patients with urge incontinence as compared with continent patients, there was no significant difference in other parameters between the two groups. Every parameter on cystometry did not correlate with nocturnal frequency. Postoperative persistence of urge incontine...Continue Reading
