目的：5%-36%的前列腺癌患者在植入放射性粒子进行近距离放射治疗后发生尿潴留。我们使用经会阴穿刺活检作为一个模型，以确定针外伤对尿潴留的影响。方法和材料：我们回顾性分析了157例前列腺癌高危男性的病历，这些患者采用经会阴模板技术和18号自动活检装置进行了系统的超声引导下前列腺活检。（11.5%; 95%可信区间，6.9%-17.5%）活检后48小时内有尿潴留。尿潴留患者的中位年龄为68.5岁，无尿潴留患者的中位年龄为67.0岁（P = 0.319）;计算的中位前列腺体积为76.5 mL与51.5 mL（p = 0.015）;活检芯的中位数量为22.0与20.0（p = 0.038）。各组之间的年龄分布不同（p = 0.047），在无保留组中有更多的年轻男性。在多变量分析中，只有活检芯的数量显著预测尿潴留（p = 0.003）。4例患者需要经尿道切除术; 1个留置导管，直到根治性尿道切除术;和13个无导管1-5 days.Conclusions：针创伤单独可能会导致尿潴留的男性接受经会阴手术。穿刺次数和前列腺大小是术后尿潴留的预测因子。(C)2004年爱思唯尔公司
Purpose: Urinary retention occurs in 5%-36% of patients with prostate cancer after implantation of radioactive seeds for brachytherapy. We used transperineal biopsy as a model to determine the influence of needle trauma on urinary retention.Methods and Material: We retrospectively reviewed medical records of 157 men with high risk of prostate cancer who underwent systematic ultrasound-guided biopsy of the prostate with the transperineal template technique and an 18-gauge automated biopsy device.Results: Eighteen of 157 patients (11.5%; 95% confidence interval, 6.9%-17.5%) had urinary retention within 48 hours after biopsy. Median age was 68.5 years in patients with retention vs. 67.0 years in patients without (P = 0.319); median calculated prostate volume, 76.5 vs. 51.5 mL (p = 0.015); and median number of biopsy cores, 22.0 vs. 20.0 (p = 0.038). Age distribution differed between groups (p = 0.047), with more younger men in the no-retention group. On multivariate analysis, only number of biopsy cores significantly predicted urinary retention (p = 0.003). Four patients required transurethral resection; 1 had an indwelling catheter until radical prostatectomy; and 13 were catheter-free within 1-5 days.Conclusions: Needle trauma alone may cause urinary retention in men undergoing transperineal procedures. The number of needle incursions and prostate size are predictors of postprocedure urinary retention. (C) 2004 Elsevier Inc.
