“…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.…”

“…2): (1) bladder shape; (2) ratio between superoinferior and anteroposterior length of bladder (SI/AP), angle between anterior and posterior wall (AAP), relative length of posterior urethra (rLPU), and angle between bladder and seminal vesicle (ABS); (3) maximal thickness of bladder trigone; and (4) hydronephrosis condition (in combination with the ultrasound inforamtion). We performed the physiologic micturition real‐time MRI for 2 LHSO cases and a cystoscopy during a mimic voiding for one LHSO case to analyze the dynamic mechanisms involved (Fig. D‐F and Supplementary video).…”

“…Later, the micturition process of naive bladders was studied via MRI [20,21] . Finally, Muto et al [4] used for the first time real-time MRI to compare dynamics of the bladder with naive bladder with that of continent patients after neobladder. The findings showed that the neobladder (n = 5) rotated and moved more dynamically during the voiding process compared to patients with naive bladder (n = 5).…”

“…Beyond this, magnetic resonance imaging (MRI) and functional dynamic (cine-or real-time) MRI in particular have been employed to assess functional pelvic floor disorders in the female pelvis and have gained importance as a valuable diagnostic adjunct in the workup of urinary dysfunctions [2,3] . Few preliminary data have been presented using real-time MRI to describe the postoperative configuration of neobladder [4] .…”
