Utility of preoperative examination and magnetic resonance imaging for diagnosis of anterior vaginal wall masses

Introduction and hypothesis

The clinical evaluation of anterior vaginal wall masses can present a dilemma, as there are no well-defined pathways for diagnosis and management. Our objective was to evaluate the role and accuracy of preoperative exam and magnetic resonance imaging (MRI) for these masses.

Methods

We identified women with a mass using billing codes for 10?years. We compared data from the preoperative evaluation to postoperative pathology if available.

Results

Analysis after chart review on 47 women was performed. Of the 34 women who had surgery, 28 (82.4%) also underwent an MRI. MRI diagnosis was accurate in 22/28 women compared to histology, inconclusive in 4, and inaccurate in 2. Preoperative diagnosis, including exam, MRI, and cystourethroscopy, had a diagnostic accuracy of 94.1% compared to postoperative diagnosis. The positive predictive value of MRI alone was 91.7%.

Conclusions

Preoperative diagnosis using exam, MRI, and cystourethroscopy have a high diagnostic accuracy for anterior vaginal wall masses.
