目的 :探讨小儿尿道下裂尿道成形术后自由尿流率测定 (uroflowmetry,UFM)的作用。方法 :36例因尿道下裂而行尿道成形术后的男性患儿 ,年龄 (4 .1± 0 .9)岁。术后 3个月均可自主排尿 ,行UFM测定。将最大尿流率小于同龄小儿正常值的 1个标准差定义为可疑梗阻 ,小于 2个标准差或尿流率曲线为平台状定义为梗阻。对可疑梗阻或梗阻的患儿行尿道镜检或尿道造影以明确梗阻部位。结果 :本组患儿 2 7例 (75 .0 % ) ,UFM示无梗阻 ,随访 1a亦未出现尿道狭窄表现。 5例示可疑梗阻 ,4例示梗阻 ;经尿道镜检或造影 8例明确梗阻部位 ;1例未发现尿道明显狭窄部位 ,但经尿道扩张后最大尿流率改善。结论 :UFM评估尿道下裂尿道成形术后尿道狭窄灵敏、有效、简单、无创 ,可在术后常规进行
Objective: To investigate the effect of uroflowmetry (UFM) after pediatric hypospadia urethroplasty. Methods: Thirty-six male patients who underwent urethroplasty due to hypospadias were aged (4.1 ± 0.9) years old. After 3 months of spontaneous urination, line UFM determination. A standard deviation of the maximum uroflow rate less than the normal pediatric age was defined as suspicious obstruction, and less than 2 standard deviations or urinary flow rate curve as platform-like obstruction. Suspicious obstruction or obstruction of children underwent urethroscopy or urethroscopy to identify obstruction site. Results: Twenty-seven patients (75.0%) in this group showed no obstruction with UFM and did not show urethral stricture at follow-up. 5 cases showed suspicious obstruction, 4 cases showed obstruction; ureteroscopy or radiography in 8 cases clearly obstruction site; 1 case did not find significant sites of urethral stricture, but the maximum flow rate after urethral dilatation improved. Conclusions: UFM assessment of hypospadia urethroplasty urethral stricture sensitive, effective, simple, non-invasive, can be routinely performed after surgery
