[Obstructive bladder neck syndrome in women].
Primary bladder neck obstruction in women is quite rare and its symptoms--dysuria, frequency, and urgency--are equivocal. Routine radiological investigations alone do not allow a diagnosis to be made, due to the lack of simultaneous measurements of detrusor pressure and urine flow. A precise diagnosis is thus to be obtained by synchronous video urodynamic studies which allow the depiction of nonfunneling or tight bladder neck during the entire phase of detrusor contraction, of bladder trabeculae and diverticula, vesico-ureteral reflux, long micturition time and incomplete voiding. When these radiological signs are associated with a rise in detrusor voiding pressure over 60 cm of water and with peak urine flow lower than 15 ml/s, the diagnosis of bladder neck obstruction is unquestionable, and the appropriate pharmacologic/endoscopic treatment can be administered.
