Brief Summary
We are conducting a randomised trial comparing outcomes of transperineal prostate biopsies under free-hand software assisted MRI/US fusion with transrectal biopsy guide software assisted MRI/US fusion. Primary outcome is the detection of clinically significant prostate cancer. Secondary outcomes is rate of complications including infection and sepsis, as well as feasibility and patient tolerability.

Study Arms (2)
Transrectal fusion biopsies of the prostate
ACTIVE COMPARATOR1. Transrectal approach, patient in left lateral position, local anestesia 10ml lidocaine 1% at prostate base laterally and apex if indicated. 2. MRI-ultrasound fusion-guided biopsies with 4 biopsy cores per lesion, where clinically indicated. 18G biopsy needle. 3. Standard 12-core template for systematic biopsies. 18G biopsy needle. 4. Antibiotic prophylaxis with 750mg ciprofloxaicin, single dose p.o.
Transperineal free hand fusion biopsies of the prostate
EXPERIMENTALMen randomized to the experimental arm undergoes free-hand targeted transperineal fusion biopsies as defined below. 1. Patient is placed supine in the lithotomy-position. The perineal area is prepared with chlorhexidine 0,5ml/ml. 2. Ropivacain 7,5mg/ml is used as an anesthetic agent. Up to 40ml's (equivalent to 300mg) can be used to anestitize the skin, caudal and cranial part of the urogenital diaphragm and periprostatic tissue. 3. Free-hand MRI-ultrasound fusion-guided biopsies with at least 4 biopsy cores per lesion. Coaxial technique with 18G biopsy needle. 4. 10-12 Systematic biopsies according to the modified Barzell 12-core template. 5. No antibiotic profylaxis unless warranted by immunosuppression, previous sepsis or urinary tract infection.
