To investigate bladder neck and urethral function after radical hysterectomy, 21 patients were investigated before and 3 months after the operation. Each patient had an excretory urogram, CO2 cysto‐scopy, uroflowmetry, water cystometry and a urethral pressure profile, using a dual sensor microtransducer catheter, at rest and during stress. Postoperatively there was a significant reduction in urethral length and urethral closure pressure; however, pressure transmission ratios were maintained, indicating no loss of bladder neck support with stress. Of the six patients with pre‐operative bladder neck weakness, two (33%) had stress urinary incontinence at the 3 months assessment. No patient with a normal pre‐operative assessment developed this complication. Fifteen (71%) voided by abdominal straining and this manoeuvre emptied the bladder effectively. These data suggest that patients with pre‐operative evidence of an incompetent bladder neck may be predisposed to develop stress urinary incontinence after radical hysterectomy because of a reduction in the urethral closure pressure.
