Synopsis

Keywords: Prostate, Diffusion Tensor Imaging, Radical prostatectomy; Urethral sphincters complex; Urinary incontinenceThe anatomical-morphological and functional characteristics of the urethral sphincter complex, a key structure in the mechanism of urinary continence, have been studied mostly based on cadaveric dissection or animal experiments. In this study,we qualitatively and quantitatively evaluated the morphology and function of the urethral sphincter complex in patients after laparoscopic radical prostatectomy (LRP) using pelvic floor MRI combined with DTI and fiber tractography, and to investigate the anatomical factors affecting PPI.
