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 ,及时防止肾积水的发生
Objective To investigate the relationship between residual urine volume changes and hydronephrosis in patients with benign prostatic hyperplasia (BPH). Methods Sixteen BPH patients were followed up for 2 years with IPSS, Qmax, PVR, and Logistic regression analysis. Results Multivariate analysis showed that the increase of PVR was related to the occurrence of hydronephrosis. The odds ratio (OR) was 25.886, the regression coefficient was 3.253, P = 0.017. There were significant differences between IPSS (P <0.01), Qmax (P <0.05) and PVR (P <0.01) in patients with surgery and non-surgery. Conclusion During BPH patients, IPSS, Qmax and regular PVR should be performed to prevent hydronephrosis in time
