    The paper is the first to assess the learning curve of robotic assisted prostate biopsy. The paper concludes the proficient performance of Robot Assisted Transperineal Fusion Biopsies (RA TP FBx) feasible as of 22 cases regardless of previous biopsy experience and presume steady accuracy due to the automatization offered by robotic technology. This is a considerable difference from the reported learning curve of other transperineal biopsy platforms 65-125 cases.

    According to the study in this paper Robotic-assisted transperineal MRI-US-fusion guided biopsy of the prostate using Mona Lisa performed under general anesthesia is a safe and well tolerated procedure. This technique allows to omit perioperative prophylaxis and at the same time minimizes the risk of infectious complications. The paper attributed the favorable risk profile and tolerability to the minimal invasive approach via two entry points of Mona Lisa.

    This paper evaluated the safety and feasibility of performing stereotactic robot-assisted transperineal MRI-US fusion targeted prostate biopsy under local anaesthesia (LA) with sedation using Mona Lisa on 30 patients . 29 of 30 patients (96.7%) were discharged within 24 h of procedure. There were no immediate severe complications. Adenocarcinoma was detected in 19/30 (63.3%) cases. This pilot feasibility study showed that stereotactic robotic transperineal MRI-US fusion targeted prostate biopsy using Mona Lisa can be safely and accurately performed under LA with sedation.

    The Journal Of Urology

    This paper aims to determine the missed clinically significant prostate cancer (CSPC) rate for target and saturation biopsies using a robotic-assisted trans-perineal MRI-Fusion biopsy platform (TP MRI-Fusion BX) and the related complications. Mona Lisa was used for all the biopsy procedures. Robotic-assisted target and saturation biopsies had a miss rate of 2.97% CSPC. This was 2 to 3 times lower than doing target only and target plus systematic biopsy.

    The primary aim of this study was to determine the clinically significant cancer detection rate (csCDR) of Transperienal (TP) targeted biopsies using robotic-assisted (RA) MRI ultrasound fusion biopsy (MFB) compared to cognitive targeted biopsies (C-TB) using a grid template as this has not previously been reported. Secondary aims were to determine differences in complications between the two methods. Robot Assisted targeted biopsy using Mona Lisa results in higher CDR for clinically significant cancers and any cancer. It also suffers lower complications compared to cognitive directed TP biopsy.

    Mona Lisa was used for performing both systematic and MRI-US fusion targeted biopsy in this retrospective study. The paper is addressing the need for systematic biopsy and the effect of the no of cores taken during systematic MRI-targeted biopsy. Reducing the number of systematic biopsies when performing an MRI-targeted biopsy leads to reduced detection of csPCa and alter the treatment plans for focal therapy, possibly limiting its oncological efficacy.

    The paper addressed the use of Mona Lisa for MRI US fusion transperineal biopsy. MRI-US Fusion has a fine balance with regards to accuracy, practicality and affordability. This review paper aims to describe the various uses of MP-MRI for prostate biopsy comparing different techniques of MP-MRI guided biopsy. The paper concludes that the use of MRI guidance in prostate biopsy is inevitable, subject to availability, cost, and experience. Any one of the three modalities (i.e. MRI cognitive, MRI US fusion and MRI in-bore approach) can be used.

    Mona Lisa was used for both systematic and targeted biopsy in this study. This paper evaluate the clinically-significant prostate cancer detection rate of systematic (SBx) vs. targeted biopsy (TBx), after accounting for the overlapping systematic cores within the MRI regions of interest. The overlapping systematic cores improve the clinically significant prostate cancer detection rate on TBx.

    TP MRI-fusion targeted and saturation biopsies were carried out using robotic-assisted iSR'obot Mona Lisa biopsy platform. CSPC was higher for biopsy-naïve patients for PSA<20 using TP MRI-Fusion biopsy. Thus, an up-front mpMRI scan prior to prostate biopsy should be offered to these patients and not restricted to patients with prior negative biopsy. EAU guidelines recommend mpMRI scan for prior negative biopsy and was expanded to include biopsy-naïve and Active Surveillance patients. However, the strength of recommendation was weak for biopsy-naïve patients. The aim of the study was to determine clinically significant prostate cancer (CSPC) rate for biopsy-naïve patients using Trans-perineal MRI-Fusion targeted and saturation biopsy (TP-Fusion-BX) compared to systemic biopsies with trans-rectal (TRUS-BX) and trans-perineal (TP-BX) US-guided biopsies and their complications.

    During the use of Mona Lisa in trizonal scheme biopsy method, the percentage of positive biopsy cores detected from target, near-target and MRI-negative zones were 66%, 39% and 17%, respectively. The addition of near-target biopsy cores led to 9% increase in detection rate of clinically significant prostate cancer (csPC). The addition of near-target zone increased the final ISUP grade by a median of one in 17% of the patient. The use of near-target biopsies as part of a trizonal biopsy schema provides a novel methodology to optimize clinically significant prostate cancer detection.

    Prostate biopsy using the first-generation iSR’obot Mona Lisa has demonstrated a high detection of clinically significant prostate cancer (csPC) when combined with only limited near-field sampling. The use of Mona Lisa in prostate biopsy demonstrated a clinically significant prostate cancer (csPC) detection rate of 51.2% and a clinically significant prostate cancer (csPC) detection rate of 40.1 % from centroid lesion targeting alone. The combination of both targeted and 12-zone template biopsy increased the csPC detection rate by 10.5% (additional 9 men) to 51.2%.

    This study aimed to assess the initial multicenter experience using the robotic device — the iSR’obot Mona Lisa — to perform MRI-US fusion transperineal biopsy. The iSR’obot Mona Lisa performs robotic MRI-ultrasound fusion transperineal prostate biopsy via two skin punctures safely and with high accuracy. Overall, targeted cores detected at least as many significant cancers as template cores. Targeted and template biopsies together is most optimal for cancer grading and detection.

    The use of Mona Lisa in this study in prostate biopsy has a prostate cancer (PC) detection rate of 61%, a clinically significant prostate cancer (csPC) detection rate of 51.2% and a csPC detection rate of 40.1% from targeted biopsy alone. While Robot Assisted targeted biopsy (RA-TB) and systematic biopsy (SB) both showed similar clinically significant prostate cancer detection rates under primary and repeat biopsy settings, RA-TB using Mona Lisa offered 50% reduction in biopsy cores. Thus, omitting RA-SB can pose substantial risk in missing clinically significant prostate cancer.

    Biopsies were performed via transperineal route under general anaesthesia with iSR’obot Mona Lisa, a robotic platform with maximal coverage of prostate using real-time 3D-ultrasound technology. Both systematic template biopsy followed by targeted biopsy by cognitive fusion was both performed using Mona Lisa. The paper investigated if a strategy of transperineal template biopsy with magnetic resonance imaging (MRI)-targeted biopsy identifies significant prostate cancer amongst men initially diagnosed with low-risk prostate cancer. A combination of MRI-targeted and template biopsy may optimally risk-classify “low-risk” patients diagnosed on initial conventional transrectal ultrasonography (TRUS) prostate biopsy.

    This study compared prostate cancer detection rates between MRI-TRUS fusion targeted and systematic biopsies using a robot-guided, software based transperineal approach using Mona Lisa. Transperineal biopsy approach using Mona Lisa allows for optimal coverage of high-risk areas of the prostate and hence increases detection rates.

MRI-targeted biopsy in tandem with robotic transperineal systematic biopsy with Mona Lisa upgrades Gleason score.
