The current recommendation in patients with a clinical suspicion for prostate cancer is to perform systematic biopsies extended with targeted biopsies, depending on mpMRI results. Following a positive mpMRI [i.e. Prostate Imaging Reporting and Data System (PI-RADS) ≥3], three targeted biopsy approaches can be performed: visual registration of the MRI images with real-time ultrasound imaging; software-assisted fusion of the MRI images and real-time ultrasound images, and in-bore biopsy within the MR scanner. This collaborative review discusses the advantages and disadvantages of each targeting approach and elaborates on future developments. Cancer detection rates seem to mostly depend on practitioner experience and selection criteria (biopsy naïve, previous negative biopsy, prostate-specific antigen (PSA) selection criteria, presence of a lesion on MRI), and to a lesser extent dependent on biopsy technique. There is no clear consensus on the optimal targeting approach. The choice of technique depends on local experience and availability of equipment, individual patient characteristics, and onsite cost-benefit analysis. Innovations in imaging techniques and software-based algorithms may lead to further improvements in this field.

“…Irrespective of the imaging modality normally prostate biopsy are performed through template grid or robotic-guidance or freehand in three different zones (i) Transgluteal: practiced in patients without rectal access due to prior colorectal surgery [ 2 ]; (ii) Transrectal: needle inserted through the rectal wall thus has a risk of contamination specially when multiple biopsies are taken place. Each needle passage risks spreading rectal bacteria in the blood stream [ 3 ]; (iii) Transperineal: needle inserted through the perineal skin.…”

“…Few studies have described computed tomography (CT)-guided sampling of the prostate, which uses noncontrast CT-guided biopsies with a transgluteal approach.

“…Without rectal access, other biopsy approaches, such as transurethral or transperineal ultrasound–guided biopsy, have been used with variable results. Few studies have described computed tomography (CT)–guided sampling of the prostate, which uses noncontrast CT-guided biopsies with a transgluteal approach 5–10 . These studies reported high success rates and excellent safety profiles, with a lack of major complications and very low rates of minor complications.…”

Objectives We aimed to present our experience and the outcomes of a novel technique, computed tomography (CT)–guided prostate biopsy and fiducial marker insertion in patients with absent rectums. Methods Patients who underwent CT-guided prostate biopsy at a single institution from November 2010 to November 2022 were retrospectively reviewed. Patients were included if they had a clinical suspicion of prostate cancer and had absent rectums from previous surgical resection. Contrast-enhanced CT scan was used to perform transgluteal prostate biopsy. Patient demographics, multiparametric magnetic resonance imaging, and biopsy details were recorded. Results Thirteen biopsy procedures and 1 CT-guided fiducial marker insertion were performed on 12 unique patients. The reasons for the absence of rectums included surgical resection for rectal cancer (n = 10) and surgical resection for inflammatory bowel disease (n = 2). Clinically significant cancer was found in 7 of 13 biopsy results (52.8%), clinically insignificant cancer in 3 of 13 (23.1%), and benign cancer in 3 of 13 (23.1%). No complications were recorded. Conclusions Our data support CT-guided prostate biopsy as an accurate and effective technique for investigating prostate cancer that requires tissue sampling in patients with absent rectums.
