压力-流率测定评价慢性前列腺炎综合征患者下尿路功能

Evaluation of pressure-flow studies for function of lowere urinary tract in chronic prostatitis syndrome patients

为了评价慢性前列腺炎综合征（ＣＰＳ）患者排尿期的下尿路功能，对７２例ＣＰＳ患者进行排尿期压力－流率－肌电图测定。结果表明：７２例ＣＰＳ患者中，逼尿肌－外括约肌协同失调的发生率为８８．９％，其中压力－流率测定有尿流形成者为起始型及间隙型，测定时无尿流出现者为持续型。逼尿肌－内括约肌协同失调者１１．１％，可分为延迟开放型、开放不全型及完全不开放型。

To evaluate the function of lower urinary tract of chronic prostatitis syndrom (CPS) were performed in 72 patients with CPS with voiding pressure-flowEMG studies. The results showed that CPS patients were with function bladder outflow obstruction (FBOO). FBOO and the detrusor contractlity was graded by passive urethral resistance relation (PURR). Detrusorsphincter dyssynergia (DSD) included 11.1% detrusorexternal sphincter dyssynergia (DISD) and 88.9% detrusorexternal sphincter dyssynergia (DESD). DESD was divided into three types:beginning type (25%), intermittent type (34.4%), sustained type (40.6%); DISD was divided into three types:delayed opening type (37.5%), incomplete opening type(50%) and complete non-opening type (12.5%). The mechanisms of FBOO, internal and external sphincter spasm, DESD and DISD were discussed.
