Abstract:
Purpose To explore the association between the anteroposterior hiatal diameter(AP)and pelvic organ prolapse(POP).Materials and Methods All clinical and transperineal ultrasound(TPUS)data of 262 women with lower urinary tract symptoms or POP who had presented to Second Xiangya Hospital of Central South University from July 2017 to May 2019 were retrospectively summarized and analyzed.AP was measured in the median sagittal section of the pelvic floor at maximum Valsalva motion.The degree of POP was obtained via international continence society(ICS)pelvic organ prolapse quantification(POP-Q)system and TPUS.The relationship between AP and POP degrees,and the predictive ability of AP on POP degrees were analyzed,respectively.Results A total of 237 patients were finally selected.There were 51(21.51％)women within ICS POP-Q stage 0,57(24.05％)within stage Ⅰ,49(20.67％)within stage Ⅱ,44(18.56％)within stage Ⅲ,36(15.18％)within stage Ⅳ.The mean AP on maximal Valsalva was(61.33±10.71)mm(range 37.10-97.90 mm).There was a significant difference in AP measurements based on TPUS or POP-Q(F=52.00,58.18,both P<0.01).A receiver operating characteristic curve analysis proposed a cutoff of 6.0 cm,and the sensitivity and specificity of prediction of obvious POP via TPUS was 81.0％and 75.5％,respectively;the sensitivity and specificity of prediction of POP-Q Ⅱ or high levels POP was 74.5％and 76.0％,respectively.AP was positively highly related to the POP stages.AP on Valsalva of less than 6.0 cm was related to POP stage 0-Ⅰ,6.0 to less than 6.5 cm was related to POP stage Ⅱ,6.5 to less than 7.0 cm to POP stage Ⅱ-Ⅲ,7.0 or more to POP stage Ⅳ(r=0.61,0.47,0.56,0.41,all P<0.05).Conclusion AP≥6.0 cm indicates an enlarged levator hiatus,with likelihood of POP.The larger the AP,the more severe the POP is.
