Study: NCT01827813

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: Transrectal prostate biopsy with ultrasonography.
Description: Transrectal prostate biopsy was performed in left lateral decubitus position with sedo-analgesia in saturation biopsy group and without sedoanalgesia in 10-12 core biopsy group on outpatient basis. After preparation of the rectal ultrasound probe and assuming an appropriate position, ultrasonographic examination of the prostate was performed on axial and sagittal plane. Periprostatic block was performed with the injection of 3 cc of prilocaine to each of the right and left lobes in the right and left periprostatic region in both groups before biopsy. Biopsy procedure was performed with an 18 G, 20 cm tru-cut biopsy needle and an automatic biopsy gun. After passing beyond the rectal mucosa, the needle was advanced until 0.5 cm proximal to the area of interest by tracking the image of the needle on the screen.

Intervention: Periprostatic block
Description: Periprostatic block was used for local anesthesia. 3 cc 2% prilocaine was injected to both periprostatic region in both saturation biopsy and 10-12 core biopsy group with transrectal ultrasonography.

Intervention: Sedoanalgesia
Description: Sedoanalgesia was used in saturation biopsy group. It was given by an anesthesiologist. Patients were given adequate counselling regarding sedoanesthesia as well as the biopsy procedure. They were advised to fast the night before the procedure.Before induction of sedoanalgesia all patients were monitorized for peripheric oxygen saturation and electrocardiography (ECG).Additionally nasal oxygen with 3ml/min was given to all patients by nasal canula.Sedoanalgesia was induced with 0.05mg/kg of midazolam, 1mg/kg of propofol and 1mg/kg of fentanyl. additional propofol was given with dose of 0.3mg/kg as patients needed.
