急性尿瀦留是泌尿科急診常見的疾病。自1988年1月至1991年1月止三年間，共132位前例腺肥大引起急性尿瀦留的病人。年齡分佈由53歲到94歲，平均70歲。膀胱漲尿由200毫升到1500毫升，平均800毫升。在急診處有102位病人接受留置性導尿管，其中43位在留置1至12天後拔除，而59位則留置到接受手術治療。另外30位病人接受單次導尿。留置導尿管組的一個月尿瀦留至再發率為39.5%，略低於單次導尿組的56.7%(p>0.1)，而留置性導尿管拔除的時間快慢與尿瀦留之再發率無關。即往史中尿瀦留及尿發炎之有無，年齡、夜尿及解尿遲緩症狀及輕重均無法預測病人是否再度發生尿瀦留。病人的漲尿若大於700毫升，或是導尿管拔除後自然解尿量小於90毫升及最大尿流率小於5ml/sec，則我們可預測這病人有較高的尿瀦留再發率，同時可建議他們接受進一步的手術治療。

One hundred and thirty-two male patients with acute urinary retention caused by benign prostatic hyperplasia were treated. Indwelling catheterization was performed in 102 patients, and in 43 of them the catheters were removed 1-12 days later. Thiryt patients received simple catheterization. Recurrent retention within one month occurred in 17 patients (39.5%) of the simple catheterization group(P>0.1). The timing of indwelling catheter removal was unimportant since recurrent retention rate was 41.7%, 36.4% and 44.4% in subgroups of <3 days, 3-7 days, >7 days respectively. Re-establishment of micturtion was not associated with the duration and severity of “prostatism” symptoms, age previous retention history, or the presence of urinary tract infection. Predictions for recurrent urinary retention of one-parameter analysis were a volume of retention of 700 ml or more, maximal flow rate of less than 5ml/sec, and voided volume of less than 90ml after removal of the catheters. Surgical intervention is highly recommanded in these patients.
