Evaluation of rectocele in patients with pelvic floor dysfunction by dynamic magnetic resonance imaging

SUMMARY

Objectives: Rectocele is a bulge or a prolapse of the anterior rectal wall into the posterior vaginal wall. It is relatively common with diversified and nonspecific symptoms. Clinical examination is easily confused and/or sometimes omitted the prolapse of other pelvic organs. Imaging to assess the pelvic floor dysfunction is an important and useful diagnostic test, especially dynamic MR.

Methods: Our study was cross-sectional descriptive. Patients with pelvic floor dysfunction were undergone clinical examinations and then were indicated to have dynamic MR scanning at Ho Chi Minh City Medical University by anorectic doctor, urologist and gynecologist.

Results: 1.863 patients were evaluated from January 2008 to June 2012. Most of them are women, middle-aged and used to give birth. The rate of rectocele with its depth from 2 to 4 cm was 77.9%, mainly with the shape of “finger”. The depth of more than 2 cm with the shape of “bag” has the high risk of stagnancy. The factor of age and being used to give birth have a significant relation with rectocele (p<0.001). The rate of rectocele in the group of anismus was 64.2%. The combination of the prolapse of more than one pelvic chamber accounted for 77.4% (p<0.001).

Conclusions: Dynamic MR of the pelvic floor helps to diagnose in details the characteristics of the rectocele and other pelvic organ prolapse, helping clinicians to choose the appropriate treatments.
