经会阴模板引导前列腺饱和穿刺活检的并发症

  目的  探讨经会阴模板引导前列腺饱和穿刺活检(transperineal template-guided prostate saturation biopsy，TTPSB)的安全性和可行性。  方法  回顾性分析苏北人民医院泌尿外科2017年3月至2018年5月收治的疑似前列腺癌行前列腺穿刺活检患者的临床资料。根据前列腺形态及大小、耻骨条件、患者意愿，将患者分为两组，一组行TTPSB，另一组行传统经会阴模板引导前列腺穿刺(transperineal template-guided prostate biopsy，TTPB)。比较两组穿刺术后并发症(出血、感染、尿潴留、排尿功能及勃起功能等)的发生情况。  结果  共纳入385例符合入选和排除标准的患者，TTPSB组204例，穿刺针数11~47针，平均(23.7±5.8)针；TTPB组181例，穿刺针数5~12针，平均(12.3±4.3)针；两组基线资料匹配。TTPSB组除中度血尿发生率较TTPB组高外19.6% (40/216)比11.6% (21/181)，P < 0.05]，其余并发症发生率两组间均无统计学差异(P均 > 0.05)。两组国际前列腺症状评分(International Prostate Symptom Score，IPSS)穿刺后1、4周较穿刺前均升高TTPSB组:15.8±6.9和12.6±7.5比10.2±6.8；TTPB组:16.2±6.7和13.2±7.1比10.7±7.2，P均 < 0.05]，穿刺后12周两组IPSS恢复至穿刺前水平(TTPSB组:11.3±6.5；TTPB组:11.9± 6.8，P均 > 0.05)。比较两组国际勃起功能指数(International Index Erectile Function，IIEF)-5评分，穿刺后1个月均较穿刺前下降(TTPSB组:18.4±4.3比19.5±4.6；TTPB组:18.8±4.8比19.9±4.5，P均 < 0.05)，而穿刺后3、6个月两组患者的IIEF-5评分(TTPSB组:18.9±4.4, 19.3±4.2；TTPB组:19.3±4.2, 19.7±4.3)与穿刺前相比均无统计学差异(P均 > 0.05)。  结论  与传统TTPB相比，TTPSB并发症不显著增加，是一种较安全的穿刺方法。

Complications of Transperineal Template-guided Prostate Saturation Biopsy

  Objective  The aim of this study was to investigate the safety and feasibility of transperineal template-guided prostate biopsy (TTPSB).  Methods  Clinical data of patients with suspected prostate cancer who were admitted for prostate biopsy in the Department of Urology at the Northern Jiangsu People's Hospital from March 2017 to May 2018 were retrospectively collected and analyzed. All patients were divided into two groups, TTPSB group and traditional transperineal template-guided prostate biopsy (TTPB) group, according to the prostate shape and size, pubic condition, and patient intention. The complications including bleeding, infection, urinary retention, urinary function, and erectile function after prostate biopsy were compared between the two groups.  Results  A total of 385 patients meeting the inclusive and exclusive criteria were enrolled in this study. There were 204 patients in the TTPSB group with mean of (23.7±5.8) cores (range from 11 to 47 cores) and 181 patients in the TTPB group with mean of (12.3±4.3) cores (range from 5 to 12 cores); the baseline information was matched between the two groups. The incidence of moderate hematuria in the TTPSB group was higher than that in the TTPB group 19.6% (40/216) vs. 11.6% (21/181), P < 0.05]; there was no statistical difference in the incidence of the other complications (all P > 0.05). The International Prostate Symptom Score (IPSS) of the two groups were increased at the 1st and 4th week after the biopsy compared with the baseline before the biopsy TTPSB group: 15.8±6.9 and 12.6±7.5 vs. 10.2±6.8; TTPB group: 16.2±6.7 and 13.2±7.1 vs. 10.7±7.2, all P < 0.05], and returned to the baseline level at the 12th week after the biopsy (TTPSB group: 11.3±6.5; TTPB group: 11.9±6.8, both P > 0.05). The International Index Erectile Function (IIEF-5) score of the two groups were decreased at the 1st month after biopsy compared with the baseline TTPSB group: 18.4±4.3 vs. 19.5±4.6; TTPB group: 18.8±4.8 vs. 19.9±4.5, both P < 0.05]; while there was no significant difference between the baseline and the 3rd and 6th month after the biopsy (TTPSB group: 18.9± 4.4 and 19.3±4.2; TTPB group: 19.3±4.2 and 19.7±4.3, all P < 0.05).  Conclusions  Compared with traditonal TTPB, the complications of TTPSB are nearly the same. TTPSB is a safe procedure.
