原则上只在怀疑前列腺癌或已确诊前列腺癌计划进行诊治时行前列腺活检。指征:①前列腺指诊怀疑癌肿。②PSA值升高:德国泌尿外科学会认为PSA值直接诊断的不是前列腺癌,而是进行活检的指征,阈值≥4ng/ml为活检指征(UrolA ,2 0 0 2 ,4 1:5 0 9)。此外,fPAS/tPSA值<2 8%和30 % ,以及PSA值1年升高0 .75ng/ml者建议穿刺活检。方法:①部位:6分仪法即在旁矢状面前列腺尖部、中部和基底部,双侧中央取标本活检,其阳性率高于指诊可疑区域的活检,但仍有2 0 %假阴性。改良方法为自前列腺侧叶外1/ 3取6个标本活检(外周区)。②数目:增加活检数目可提… 相似文献

Impact of transrectal ultrasound guided prostate biopsy on quality of life: a prospective randomized trial comparing 6 versus 12 cores 总被引:1,自引:0,他引:1
PURPOSE: Recent studies advocating an increase in the number of cores of sextant transrectal ultrasound guided biopsy of the prostate to improve the cancer detection rate often have not addressed the impact on quality of life. We performed a prospective randomized trial comparing 6 to 12 prostate biopsy cores to determine the impact on the cancer detection rate, pain and morbidity, and quality of life. We report the impact on health related and screening specific quality of life in men undergoing 6 versus 12 core transrectal ultrasound guided prostate biopsy. MATERIALS AND METHODS: We prospectively randomized 244 men with a mean age plus or minus standard deviation of 65 +/- 8 years, serum total prostate specific antigen between 2.5 and 20.0 ng./ml., and/or digital rectal examination findings suspicious of cancer to undergo 6 or 12 core peripheral zone tissue biopsy. Of the men 71 (29%) were black. All patients completed a self-administered questionnaire before, and 2 questionnaires 2 and 4 weeks after the procedure. Health related quality of life was measured using 2 subscales (emotional well-being and role limitation due to physical health) of the short form 36-Item Health Survey. Screening specific quality of life was addressed by questions on the functional consequences of the procedure (return to daily activity, work-employment and sports-exercise). Health related and screening specific quality of life responses were compared in the groups. RESULTS: After controlling for cancer diagnosis, patient age, race, education, report of pain and baseline emotional well-being there was no significant difference in the mean change in emotional well-being scores at 2 and 4 weeks in the 6 and 12 core groups (p = 0.7 and 0.3, respectively). Similarly after controlling for these factors and baseline role limitation due to physical health there was no significant difference in the mean change in role limitation due to physical health scores at 2 and 4 weeks in the 2 groups (p = 0.3 and 0.5, respectively). There was no difference in the percent of men returning to routine daily activity (p = 0.6), work-employment (p = 0.5) or sports-exercise (p = 0.3) at 0 to 1, 2 to 3 and 4 to 7 days or longer than 1 week after the procedure in the groups. CONCLUSIONS: Doubling the sextant biopsy does not affect the quality of life in regard to emotional well-being, role limitation due to physical health, or return to routine daily activity, work-employment or sports-exercise. 相似文献

目的:比较经直肠及经会阴两种前列腺穿刺活检术的阳性率及并发症。方法:回顾性分析2009年1月至2014年1月间156例前列腺穿刺活检病例,其中经直肠径路97例,经会阴径路59例。结果:经直肠径路组穿刺阳性率为48.4%,经会阴径路组为44.1%。根据不同的PSA水平分层,两种径路穿刺活检的阳性率无显著性差异(P0.05)。穿刺后经直肠径路组与经会阴径路组血尿发生率分别为54.6%、42.4%,尿频尿急尿痛发生率分别为17.5%、22.0%,排尿困难发生率分别为9.3%、6.8%,急性尿潴留发生率分别为7.2%、6.8%,上述并发症发生率在两组间差异无统计学意义(P0.05);发热发生率分别为15.5%、3.4%,血便发生率分别为50.5%、3.4%,经直肠径路组要显著高于经会阴径路组(P0.05及P0.01);会阴肿胀发生率分别为3.1%、13.6%,经会阴径路组显著性增高(P0.05)。结论:超声引导下经直肠和经会阴前列腺穿刺活检术都是诊断前列腺癌的有效方法。两种方式的穿刺阳性率无显著性差异,但并发症发生率各有特点,具体方式选择应根据患者情况决定。 相似文献

BACKGROUND: The Gleason grading system is currently the world's most commonly used histological system for prostate cancer. It provides significant information about the prognosis. Therefore, Gleason score is accepted as an important factor in therapeutic decision-making for prostate cancer. This retrospective study assessed the correlation of transrectal ultrasound (TRUS) guided biopsy and radical prostatectomy specimens in terms of Gleason scores. METHODS: We reviewed the records of 103 patients who underwent radical prostatectomy due to clinically localized prostate cancer. The Gleason scores of the TRUS biopsies were compared with the respective Gleason scores of surgical specimen. RESULTS: In 28.7% of cases, the TRUS biopsy score was the same as that of the radical prostatectomy specimen. The most significant discordance was the upgrading of well-differentiated tumors after surgery in 71.7% of cases. However, in 81.8% of cases with high Gleason score on TRUS, biopsy was correlated with poorly differentiated tumor after surgery. CONCLUSIONS: Well-differentiated tumors on TRUS biopsy did not correlate with the grades of final pathology in the majority of cases; however, a high Gleason score on TRUS biopsy usually indicated a poorly differentiated tumor on prostatectomy specimen. Therefore, the treatment algorithms for particularly well-differentiated tumors should not be deduced from biopsy histology alone. 相似文献

PURPOSE: There is growing interest among urologists on the need for decreasing pain during transrectal ultrasound (TRUS) guided prostate biopsy. MATERIALS AND METHODS: We performed a systematic MEDLINE search of clinical trials of any kind of anesthesia, analgesia or sedation during TRUS guided prostate biopsy published since 2000. We critically analyzed the impact of pain and discomfort associated with the procedure, the described methods for evaluating it and the different techniques that have been described. RESULTS: There is strong evidence in the current literature that patient tolerance and comfort during TRUS guided prostate biopsy can be improved by anesthesia/analgesia. What remains is the need to urge all urologists to introduce it in clinical practice as a routine part of the procedure, whatever the biopsy scheme. CONCLUSIONS: Of the various options periprostatic anesthetic infiltration has been shown to be safe, easy to perform and highly effective. It should be considered the gold standard at the moment, even if the optimal technique remains to be established. Further studies addressing this issue are warranted. 相似文献
