245例前列腺增生患者尿流动力学的结果分析

本文采用自制半卧位尿动力测定床及Ｄａｎｅｃ尿动力仪器，常规行尿流率，压力－流率（同步测定尿道外括约肌肌电图），尿道测压。结果明确诊断ＢＯＯ１６１例，可疑５０例，合并逼尿肌功能受损６５例；膀胱顺应性降低７０例，外括约肌功能失调１１４例；逼尿肌不稳定５９例。最大尿流率受测压导管影响；功能尿道长度与经直肠Ｂ超测定的前列腺尿道长度相关联。结论：１、ＢＰＨ的排尿症状的机械因素与动力学因素共同作用的结果；尿动力学检查是诊断由ＢＰＨ所致ＢＯＯ的一个非常重要的手段，但分析结果时应考虑干扰因素的影响。２、功能性尿道长度与前列腺部尿道长度相关联。

Urodynamic analysis in 245 patients with benign prostatic hypertrophy

To research the mechanism of voiding disorder and promote the diagnosis rate and the accuracy of the bladder outlet obstruction,the full set of urodynamic exam were examined with self made semi supine bed and Manneu Danec Urodynamic device in 245 patients.The results showed that the diagnosis rate of BOO is 86.1%,concomitantly detrusor muscle impact in 65 cases,bladder compliance decreased in 70 cases,urethral sphincter dyssynergia in 114 cases,and unstable bladder in 59 cases.There is a close relation between the functional urethral length tested by both urodynamic and ultrasound B.It suggested that both the dynamic and mechanical factors are attributed to the voiding disorder in patients with BPH.The urodynamic exam plays an important role in diagnosis of BOO.
