Abstract:
Objective To evaluate the diagnostic efficacy of magnetic resonance defecography(MRD)in moderate or severe pelvic organ prolapse(POP)complicated with stress urinary incontinence(SUI).Methods Patients with grade Ⅱ or above POP were prospectively selected,and divided into POP combined with SUI group and isolated POP group.The MRD parameters of pelvic dysfunction between groups were analyzed to clarify the clinical diagnostic value and to evaluate the diagnostic efficacy of MRD in POP combined with SUI.Results This study enrolled 99 POP patients,42 patients in isolated POP group,and 57 patients in POP combined with SUI group.The comparison between groups showed there were significant differences in the function of the urethra and bladder,including the position of the urethro-vesical junction(1.61 cm±1.03 cm vs 2.13 cm±0.71 cm),the position of the posterior bladder wall(4.13 cm±2.46 cm vs 5.23 cm±2.21 cm),the urethra angle(94.22°±35.62°vs 114.28°±35.55°),the length of the closed urethra(2.28 cm±0.90 cm vs 2.15 cm±0.65 cm),and bladder funneling(23.81％vs 45.61％),all the differences were statistically significant(P＜0.05).The area under the curve(AUC)of multiple parameters MRD in the diagnosis of SUI was 0.73.The AUC in diagnosis of SUI by MRD combined with clinical history was 0.95.Conclusion POP combined with SUI has characteristic MRD signs.MRD technology can assist clinicians and improve the preoperative diagnosis rate of moderate and severe POP combined with SUI.
