我們分析518位成年患者的排尿膀胱尿道攝影，結果發現其中19位男性(7.45%)及16位女性(6.08%)可見膀胱輸尿管逆流。11位患者(男：女=4：7)為自發性逆留，24位(男：女=15：9)為續發性逆流，共有16位患者接受手術治療，其餘19位給予口服抗生素。結果發現腎臟功能的變化主要取決於原先腎功能好壞及逆流程度，而與治療方法較無相關。對於續發性逆流患者，以外科治療效果較佳，特別是逆流程度較高，而腎功能正常者。

A retrospective analysis of the voiding cystourethrographys(VCUG) on 518 adults was performed. Vesicoureteral reflux (VUR) was found in 19 mlaes (7.45%) and 16 females (6.08%). Of these, 11 patients (4 males, 7 females )were primary reflux, 24 patients (15 males, 9 females) were sceondary reflux. Sixteen patients were managed surgically, and 19 cases with oral prophylactic antibiotics. Follow-up serum creatinine level showed that the outcome of renal function is determined mainly by the preexisted renal functional status and grade of reflux rather than the method of treatment. If analysized separatively, patients with secondry reflux had better outcome when treated surgically.
