[Functional changes in urethra secondary to partum vs cesarean section. Evidence with dynamic perfilometry]

The vaginal delivery produces anatomic and functional disease in the pelvic floor. The urethral profilometry, part of urodynamic study, represents graphically the urethral functionality.

To determine the functional changes in the dynamic profilometry in women with antecedent of vaginal delivery or cesarean section.

This is a correlation transversal study of 310 urodynamic studies in the Uroginecology Coordination, National Institute of Perinatology at 2003.

We found a statistically significant correlation between vaginal delivery and urethral close area and the continence area, determining that a higher number of vaginal deliveries is associated with lower urethral close area and lower continence area.
