Abstract:
Objective To determine the rate of hemorrhagic complications and the possible risk factors in transrectal ultrasound(TRUS)guided prostate biopsies.Methods TRUS guided prostate biopsies were carried out in 252 patients.Chi-aquare test,t test,conditional Logistic regression were used to comparatively analyze the risk factors(age,presence of prostate cancer,the volume of prostate,arterial hypertension,diabetes mellitus,use of acetylsalicylic acid and anticoagulant,number of samples)between hemorrhagic patients and non-hemorrhagic groups.Results Hematuria was the most frequent sing in all complications,corresponding to 19.1% of the cases.According to the general feature analysis between two groups,age and the volume of the prostate were significant different.Multiple factor Loigistic regression analysis showed that patients with or without hemorrhagic complications were significant differences in age(OR=0.97,95% CI:0.942～1.000)and the volume of the prostate(OR=0.989,95% CI:0.9790～0.999).Patients with or without hematuria were significant differences in presence of prostate cancer(OR=0.479,95% CI:0.236～0.975),the volume of the prostate(OR=0.987,95% CI:0.976～0.999)and use of acetylsalicylic acid and anticoagulant(OR=3.589,95% CI:1.133～11.366).Conclusions TRUS guided prostate biopsy is a safe and effective procedure.Age and the volume of prostate are influencing factors for hemorrhagic complications.Presence of prostate cancer and the volume of prostate are influencing factors for hematuria.Use of acetylsalicylic acid and anticoagulant are risk factors for hematuria after biopsy.
