Bladder neck mobility in continent nulliparous women.
OBJECTIVE
To evaluate the mobility of the vesical neck during coughing and valsalva in healthy nulliparous volunteers and to test the reliability of the technique applied.


METHODS
Clinical observational study.


METHODS
Department of Obstetrics and Gynaecology, Cantonal Hospital Lucerne, Switzerland.


METHODS
Thirty-nine nulliparous volunteers.


METHODS
Vesical neck motion was assessed with perineal ultrasound. Intra-abdominal pressure was controlled for with an intrarectal probe. Intra-rater reliability was evaluated.


RESULTS
Vesical neck mobility was significantly lower during coughing (8 mm, SD 4 mm) than during valsalva (15 mm, SD 10 mm) (P < 0.005). Between individuals mobility varied from 4 mm to 32 mm during coughing and from 2 mm to 31 mm during valsalva. Test-retest-studies showed a maximum difference between to tests during coughing of 4 mm and during valsalva of 5 mm.


CONCLUSIONS
The bladder neck is mobile in normal continent women and bladder neck mobility is lower during coughing than during Valsalva.
