“…Thus, the contraction of the PRM is hypothesized to contribute to both urinary and fecal continence functions [ 9 26 ]. Additionally, clinical studies suggest that injury to PFM such as the PRM impacts urinary continence in women [ 27 28 ]. However, the exact role of the PRM and its function in urinary continence in males after RP remains unclear.…”

Purpose Puborectalis muscles (PRM) and ischiocavernosus muscles (ICM) play important roles in urinary continence and male erectile functions. Understanding of anatomy and surgical-injury related changes to these muscles is critical to monitor changes in continence or erectile function. Anatomical description of these muscles has undergone revisions because these conclusions were derived from cadavers. Our objectives were to: (i) elucidate male pelvic muscles by in-vivo magnetic resonance imaging (MRI) and 3-dimensional (3-D) reconstruction of these images and (ii) compare PRM and ICM thickness in healthy volunteers and symptomatic patients. Materials and Methods Healthy young male (mean age, 25 years; n=5), older male (age, 65–70 years; n=5), and post-prostatectomy patients with erectile dysfunction and urinary incontinence (age, 65–70 years; n=5) were scanned on a 3T-magnetic resonance scanner. Images were acquired from slices above urinary bladder base to urethra entry into penis. Pelvic bone, bladder/urethra, corpus cavernosum, ICM, PRM, and prostate were segmented. 3-D models of each structure were generated and assembled into composite images, and ICM and PRM thicknesses were calculated. Results We successfully reconstructed 3-D male pelvic floor anatomy including ICM, PRM, bladder, urethra, bulbospongiosus, corpus cavernosa, prostate and bones from the two groups. We documented significant reduction in PRM and ICM thickness in older men. Conclusions This is perhaps the first 3-D reconstruction of male pelvic floor structures based on in-vivo MRI in healthy and symptomatic patients. Observed reduction in PRM and ICM thickness is possibly due to age-related atrophy.

Predictive role of measurement of pelvic floor muscle thickness with static MRI in stress and mixed urinary incontinence

Abstract: Morphologic changes of pelvic floor muscle thickness can be demonstrated by a static pelvic MRI, and this can be used as a prognostic test in the treatment and follow-up of patients with stress or mixed urinary incontinence.
