分析尿道内口开放长度与膀胱膨出程度的关系

Analysis of the correlation between the length of internal urethral orifice opening and degree of cystocele

目的分析经产妇尿道内口开放长度与膀胱膨出程度(Green分型)的关系。方法300例膀胱膨出并尿道内口开放的盆底功能障碍经产妇,均进行经会阴超声检查。分析尿道内口开放长度与膀胱膨出程度的关系。结果尿道内口开放长度<0.3 cm患者中GreenⅠ型占比最高,为59.76%(49/82);尿道内口开放长度0.3~0.5 cm患者中GreenⅠ、Ⅱ、Ⅲ型占比呈现递增趋势,分别为0(0/126)、36.51%(46/126)、63.49%(80/126);尿道内口开放长度>0.5 cm患者中GreenⅠ、Ⅱ、Ⅲ型占比也呈现递增趋势,分别为0(0/92)、8.70%(8/92)、91.30%(84/92)。GreenⅠ型患者中尿道内口开放长度<0.3 cm占比最高,为100.00%(49/49);GreenⅡ型患者尿道中尿道内口开放长度0.3~0.5 cm占比最高,为55.42%(46/83);GreenⅢ型患者中尿道内口开放长度>0.5 cm占比最高,为50.00%(84/168)。不同尿道内口开放长度患者的Green分型比较,差异具有统计学意义(P<0.05)。结论尿道内口开放长度以及开放形态直接影响膀胱膨出Green分型的严重程度,尿道内口开放长度越长,膀胱膨出程度越重;尿道内口开放长度的评估使得膀胱膨出Green分型的超声诊断依据更加丰富,且更加敏感。

Objective To analyze the correlation between the length of internal urethral orifice opening and degree of cystocele(Green classification)of in multiparous women.Methods Transperineal ultrasound was performed in 300 maltiparous women with pelvic floor dysfunction who had cystocele and internal urethral orifice opening.The correlation between the length of internal urethral orifice opening and degree of cystocele was analyzed.Results When the length of internal urethral orifice opening was<0.3 cm,the proportion of Green typeⅠwas the highest as 59.76%(49/82);However,when the length of internal urethral orifice opening was 0.3-0.5 cm,the proportion of Green typeⅠ,ⅡandⅢpatients showed an increasing trend,which were 0(0/126),36.51%(46/126)and 63.49%(80/126)respectively;When the length of internal urethral orifice opening was>0.5 cm,the proportion of Green typeⅠ,ⅡandⅢalso showed an increasing trend,which were 0(0/92),8.70%(8/92),and 91.30%(84/92),respectively.Green typeⅠpatients had the highest percentage of length of internal urethral orifice opening<0.3 cm,which was 100.00%(49/49),Green typeⅡpatients had the highest percentage of length of internal urethral orifice opening of 0.3-0.5 cm,which was 55.42%(46/83),and Green typeⅢpatients had the highest percentage of length of internal urethral orifice opening>0.5 cm,which was 50.00%(84/168).Conclusion The length and shape of internal urethral orifice opening directly affected the severity of Green classification of cystocele.The longer the length of internal urethral orifice opening,the more severe the cystocele.The evaluation of the length of the internal urethral orifice opening makes the ultrasonic diagnosis of Green classification of cystocele informative and more sensitive.
