12ヵ月以上尿道ステントを留置しえた,7例の手術非適応前立腺肥大患者に対する尿道ステントの長期成績を報告した。12ヵ月後の最大尿流率(MFR)は11.2±5.39ml/secで平均尿流率(AFR)は5.9±3.94ml/secであった。尿路感染もなく,ステントの位置の移動もなく,血液生化学上の腎機能以上もなく安全と考えられたSeven consecutive patients with acute retention due to benign prostatic hyperplasia, were treated by insertion of an intraurethral stent using endoscopy under mucosal anesthesia. The patients were between 68 and 86 years old with an average age of 79.7 years. During the 1-year follow-up period all patients had satisfactory voiding. No complication or renal dysfunction were found. This device is a good alternative to an indwelling catheter in patients awaiting prostatic surgery and also in those who are either unfit or unwilling to undergo prostatectomy.
