چکیده
Methods This is a prospective, double blind study. Fifty female patients, 20 to 50 (mean 35) years old, were evaluated in two study groups: group1 30 patients with vaginal delivery and episiotomy and group2 20 patients with caesarean operation and without episiotomy (control for episiotomy). The patient selection was done clinically. Pelvic magnetic resonance (1.5T) examinations with turbo spin-echo sequences, T1 and T2 weighted, on axial, coronal and sagittal were analyzed by two different radiologists. The pelvic muscular groups were analyzed separately according to its location and grade of atrophy: pubococcygeal, iliococcygeal, puborectal, coccygeal and urethral sphincter muscles. The normal thickness pattern in normal women exams was previously evaluated in the literature . Atrophy was characterized comparing the results to the average and standard deviation of these normal measures. Qualitative assessment was also performed in parallel. Statistic analysis included Qui-squared test (χ) and Kappa test with significance interval of 95% (p<0.05). The software adopted was the Stata Inc.
