Ten individuals also underwent cystography and sequential testing over 96 h. Twenty-three per cent of did not require subsequent prostatectomy. Inability initiate a voiding contraction during cystometry at the time was associated prolonged duration greater retained volume. The internal urethral meatus is closed in retention, release results an increase profile length maximum closure pressure decrease pressure. Free catheter drainage reduction bladder capacity appearance detrusor instability.
