本文对120例患者进行了尿流率测定,并对其测得结果进行分析,认为有下尿路梗阻疾患的诊断中,最大尿流率及排尿时间是衡量下尿路排尿功能重要的指标。本组87例下尿路梗阻患者最大尿流率不正常者达92%,其尿流曲线为不同程度低平曲线。强调尿流率测定需结合临床。本方法简便,无损伤性,为评价下尿路功能提供客观指标。 In this paper, 120 patients were measured urinary flow rate and the measured results were analyzed, that the diagnosis of lower urinary tract obstruction disease, the maximum flow rate and urination time is a measure of urinary urinary tract function is an important indicator. The group of 87 cases of urinary tract obstruction in patients with maximal urinary flow rate was 92%, the urinary flow curve of varying degrees of low-level curve. Stress urinary flow rate measurement should be combined with clinical. The method is simple and non-invasive, and provides an objective index for evaluating the function of lower urinary tract.
