Pelvic magnetic resonance imaging for assessment of the efficacy of the Prolift system for pelvic organ prolapse.

OBJECTIVE

The purpose of this study was to compare pre- and postoperative pelvic organ prolapse-quantification (POP-Q) and magnetic resonance imaging (MRI) measurements in patients who undergo total Prolift (Ethicon, Inc, Somerville, NJ) colpopexy.

STUDY DESIGN

Pre- and postoperative MRI and POP-Q examinations were performed on patients with stage 2 or greater prolapse who underwent the Prolift procedure. MRI measurements were taken at maximum descent. Correlations between changes in MRI and POP-Q measurements were determined.

RESULTS

Ten subjects were enrolled. On MRI, statistically significant changes were seen with cystocele, enterocele, and apex. Statistically significant changes were seen on POP-Q measurements for Aa, Ba, C, Ap, Bp, and GH. Positive correlations were demonstrated between POP-Q and MRI changes. Minimal tissue reaction was seen on MRI.

CONCLUSION

The Prolift system is effective in the surgical management of pelvic organ prolapse as measured by POP-Q and MRI. Postoperative MRIs support the inert nature of polypropylene mesh.
