MRI分区定位联合双指引导经会阴前列腺穿刺活检在前列腺癌诊断中的应用分析

MRI partition positioning combined double refers to guide the perineal prostate biopsy in the diagnosis of prostate cancer

目的探讨MRI分区定位联合双指引导经会阴前列腺穿刺活检在前列腺癌诊断中的应用价值。方法对15例临床前列腺特异性抗原(prostate specific antigen,PSA)升高患者行MRI检查并进行12分区,分区与经会阴穿刺方向、区域一致,然后行双指引导经会阴前列腺穿刺术,即在双指引导经会阴前列腺穿刺的基础上,增加MRI分区异常区域的穿刺点。分析前列腺穿刺针数、阳性率、并发症发生率。结果 15例中穿刺针数共计189针,阳性针数99针(52%),阳性病例12例(80%),术后血尿2例,发热1例。结论采用MRI分区定位联合双指引导经会阴前列腺穿刺活检的方法,提高了前列腺癌穿刺阳性率,避免了对直肠的直接损伤,同时降低了术后感染、肠瘘等并发症的发生率,操作简单,有利于在基层医院开展,是诊断前列腺癌的可靠、有效方法。

Objective to explore the MRI partition positioning combined double refers to guide the perineal prostate biopsy in the diagnosis of prostate cancer. Methods 15 cases of prostate specific antigen（prostate specific antigen PSA）and 12 patients with elevated MRI partition,partition and the perineum puncture direction and area,and then line double refers to guide the perineal prostate puncture,namely in double refers to guide the perineal prostate biopsy,on the basis of the puncture point increase abnormal MRI partition area. Analysis of the prostate needle number,positive rate and complications. Results 15 cases of needle count a total of 189 needles,99 positive needle（52%）,12 cases（80%）positive cases,hematuria in 2 cases,postoperative fever in1 case. Conclusion MRI partition positioning combined double refers to guide the perineal prostate biopsy method,improve the positive rate of prostate biopsy,avoids direct injury to the rectum,and reduce the incidence of postoperative complications such as infection,intestinal fistula,simple operation,to carried out in grass-roots hospitals,is a reliable and effective method in diagnosis of prostate cancer.
