Changes in penile length after radical prostatectomy: investigation of the underlying anatomical mechanism

To measure changes in penile length (PL) over time before and after radical prostatectomy (RP), and to investigate the underlying mechanisms for these changes.The stretched PL (SPL) of 102 patients was measured before, 10 days after, and at 1, 3, 6, 9, 12, 18 and 24 months after RP. The perpendicular distance from the distal end of the membranous urethra to the midline of the pelvic outlet was measured on mid-sagittal magnetic resonance imaging...
