排尿期尿道测压的临床应用

Clinical use of mituritional urethral pressure profilometry

目的：确定下尿路梗阻及其梗阻部位。方法：对４１ 例有下尿路梗阻症状患者进行了排尿期尿道测压（ Ｍ Ｕ Ｐ Ｐ），其中包括前列腺增生症（ Ｂ Ｐ Ｈ）２９ 例，男性尿道狭窄 ３ 例，逼尿肌外括约肌协同失调 ３ 例，女性压力性尿失禁 ４ 例，女性尿道末端缩窄综合征１ 例，前列腺炎 １ 例。结果：２９ 例 Ｂ Ｐ Ｈ 患者中，２６ 例有梗阻，其中梗阻位于膀胱颈部 ２０ 例；３ 例逼尿肌外括约肌协同失调患者表现为外括约肌部压力下降；４ 例女性压力性尿失禁患者表现为尿道末端 １ ｃｍ 压力下降。结论：根据 Ｍ Ｕ Ｐ Ｐ图形，对下尿路有否梗阻及梗阻的部位可作出明确诊断。

Purpose: To confirm lower urinary tract obstruction and its position. Methods: The micturitional urethral prossure profilometry (MUPP) were measured in 42 patients with lower urinary tract symptom. Of which 30 cases were benign prostatic hyperplasia(BPH), 3 urethral stricture, 3 detrusor external sphincter dyssynergia, 4 the female stress incontinence, 1 the female urethral meatal stenosis and 1 prostatitis. Results: 26 cases had obstruction in 29 patients with BPH. The external sphincter pressure decreased in 3 detrusor external sphincter dyssynergia. The pressure of 1 cm terminal urethra decreased in 4 the female stress incontinence. Conclusions: According to MUPP, lower urinary tract obstruction and its position can be confirmed.
