盆腔器官脱垂对下尿道功能影响的尿动力学研究

Urodynamic study on the influence of pelvic organ prolapse on low urinary tract function

摘要

摘要: 目的:探讨盆腔不同部位器官脱垂对排尿功能的影响。方法:回顾性分析685例不同程度盆腔器官脱垂患者的临床资料及尿动力学检查结果。结果:与无前盆腔器官脱垂组相比,前盆腔器官脱垂组年龄大、绝经患者比例高、阴道分娩次数多、剖宫产比例低、合并压力性尿失禁的患者比例少,尿动力学检查显示患者强烈排尿欲膀胱容量、最大膀胱容量、初始排尿时逼尿肌压力和残余尿量均增大,平均尿流率和最大尿流率明显降低,排尿时间明显延长(P<0.05~P<0.01);而与无中后盆腔器官脱垂组相比,中后盆腔器官脱垂组绝经患者比例高、合并压力性尿失禁的患者比例少且尿动力学检查显示残余尿量明显增大,排尿时间明显延长(P<0.05~P<0.01)。结论:前盆腔器官脱垂明显增加了尿道阻力,是导致排尿功能障碍的原因之一。

Abstract: Objective: To explore the influence of pelvic organ prolapse(POP) on low urinary tract function.Methods: A retrospective analysis of 685 cases of POP was carried out,and the clinical data and urodynamic parameters were analyzed.Results: Compared with the non-anterior POP group,the anterior POP group was older in age,had a higher percentage of menopause and vaginal delivery,and fewer cases of stress incontinence;the urodynamic parameters showed that the maximum bladder capacity,detrusor pressure and residual urine volume were increased,the maximum and average urine flow rates were decreased,and the time of urinating was significantly prolonged(P<0.05-P<0.01).Compared with the non-posterior POP group,the posterior POP group had a higher percentage of menopauses and fewer cases of stress incontinence,and the residual urine volume and the time of urinating were significantly increased(P<0.05-P<0.01).Conclusions: Anterior POP may cause urethral obstruction,and is one of the responsible factors for voiding dysfunction.
