前列腺增生症病人待机处理期间剩余尿量测定的临床意义

Significance of post void residual urine in watchful waiting patients with benign prostatic hyperplasia

目的 探讨待机处理的前列腺增生症 (BPH)病人剩余尿量变化与肾积水的关系。 方法 对 16 8例BPH病人进行为期 2年的IPSS、最大尿流率 (Qmax)、B超剩余尿量 (PVR)检测随访 ,与肾积水的关系进行Logistic回归分析。 结果 多因素分析显示PVR增加与肾积水的发生有关 ,比值比 (OR值 ) 2 5 .86 8,回归系数 3 .2 5 3,P =0 .0 17。手术与非手术病人比较IPSS(P <0 .0 1)、Qmax(P <0 .0 0 5 )和PVR(P <0 .0 0 1) ,差异有显著性意义。 结论 待机处理期间BPH病人应施行IPSS、Qmax和定期PVR测定 。

Objective To observe the post void urine (PVR) of watchful waiting patients with benign prostatic hyperplasia (BPH) and to study its correlation with hydronephrosis. Methods 168 BPH patients were checked up for more than 2 years by means of IPSS,maximum flow rate (Qmax) and PVR.The correlation of PVR with hydronephrosis was studied and analyzed using logistic regression. Results Increasing of PVR was conspicuously related to the occurrence of hydronephrosis ( P <0.017) with regression coefficient being 3.253 and OR of 25.868. Between the operative and the non operative patients, there was an obvious differences in IPSS ( P <0.01), Qmax ( P <0.005) and PVR ( P <0.001). Conclusions Inspection of IPSS and Qmax especially PVR is beneficial to PBH patients on watch in order to shift to surgical management timely so as to avoid hydronephrosis
