Perineal ultrasonography in postoperative assessment of two different surgical procedures for stress urinary incontinence.

Thirty-eight incontinent and 57 continent patients who had undergone MMK urethropexy and anterior colporrhaphy procedures were examined by perineal ultrasonography. Bladder neck hypermobility was described with ventrodorsal and cephalocaudal directional parameters. In the incontinent patients both cephalocaudal and ventrodorsal mobilities were found to be significantly greater compared to the continent group, the latter ultrasonographic parameter being relatively more significant (P < 0.01 and P < 0.001, respectively). In surgically cured patients who underwent the MMK procedure both ventrodorsal and cephalocaudal mobility had been significantly limited in contrast to their incontinent counterparts; but these differences had been detected only in ventrodorsal mobility by the anterior colporrhaphy procedure.
