RESUMO
Objective To discuss the opportunity of transurethral resection of prostate (TURP) after transrectal prostate biopsy.Methods We analyzed 60 cases of benign prostatic hyperplasia(BPH) who underwent TURP after transrectal prostate biopsy from September 2013 to September 2015.All the patients were divided into either group A or group B in chronological order, with 30 cases in each group.There were no significant differences in age, prostate specific antigen (PSA), prostate volume, hemoglobin level, and international prostate symptom score (IPSS) between the two groups.The group A and group B were treated by TURP at 1 week and 4 weeks after transrectal prostate biopsy, respectively.The parameters including operation time, excised prostate weight, intraoperative total blood loss, bladder irrigation time, and IPSS at 3 months after operation were recorded.Results The operation time, intraoperative total blood loss, bladder irrigation time, and IPSS in the group B were significantly lower than those in the group A [(58.3±6.0) min vs.(62.0±3.3) min, t=2.952, P=0.005;(154.1±15.8) ml vs.(167.4±29.5) ml, t=2.181, P=0.035;(19.2±0.8) h vs.(20.6±2.3) h, t=3.034, P=0.004;(18.3±2.5) points vs.(20.3±2.0) points, t=3.419, P=0.001].The excised prostate weight in the group B was significantly higher than that in the group A [(37.1±4.0) g vs.(33.3±7.8) g, t=-2.341, P=0.024].Conclusions TURP performed at 4 weeks after transrectal prostate biopsy can significantly increase the excised prostate weight, reduce intraoperative total blood loss volume, shorten the operation time and postoperative bladder irrigation time, and improve urinary symptoms.In brief, we recommend that TURP be executed at 4 weeks after transrectal prostate biopsy.
