“…In female patients undergoing RC and bladder substitution, preservation of the uterus resulted in better functional voiding outcomes [23,24]. Real‐time MRI of neobladder voiding indicated that the neobladder rotated and moved more dynamically than the native bladder during micturition [25]. Therefore, the authors believe that anatomical or mechanical factors, including configuration of the reservoir creation, acute neocystourethral angle due to the downward migration of the ONB, failure to maintain periurethral supporting structures, cystocele formation, absence of sufficient funnelling of the neobladder neck, excessive urethral length and preservation of the bladder neck, play critical roles in insufficient emptying.…”
