Abstract:
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.
