前立腺全摘除術後における排尿状態と国際前立腺症状スコア(I-PSS)との検討

PURPOSE: We evaluated condition of urination and International Prostate Symptom Score (I-PSS) after radical prostatectomy. PATIENTS AND METHODS: Forty-three men with prostatic cancer underwent radical prostatectomy between October 1993 and October 2002. Mean patients age was 66 years (range 56 to 79) and clinical follow-up averaged 38.6 months (range 3 to 84). Urodynamics studies including uroflowmetry, cystometry and evaluation of I-PSS were performed before and 1, 3, 6, 12 months after the operation. After 12 months these studies were performed every year. The status of postoperative urinary incontinence was based on patients' report. RESULTS: First desire to void, maximum desire to void and maximal flow rate was decrease temporarily after radical prostatectomy. However most patients had normal uroflowmetorogram and normal cystometrogram at 6 months. I-PSS and QOL index was improved during postoperative 12 months. CONCLUSIONS: Postoperatively urodynamics studies was improved from 3 to 6 months, but evaluation of I-PSS and QOL index was improved from 6 to 12 months. The difference was formed to both.
