Multiparametric magnetic resonance imaging (MP-MRI) helps to identify lesion of prostate with reasonable accuracy. We aim to describe the various uses of MP-MRI for prostate biopsy comparing different techniques of MP-MRI guided biopsy.
A literature search was performed for "multiparametric MRI", "MRI fusion biopsy", "MRI guided biopsy", "prostate biopsy", "MRI cognitive biopsy", "MRI fusion biopsy systems", "prostate biopsy" and "cost analysis". The search operation was performed using the operator "OR" and "AND" with the above key words. All relevant systematic reviews, original articles, case series, and case reports were selected for this review.
The sensitivity of MRI targeted biopsy (MRI-TB) is between 91%-93%, and the specificity is between 36%-41% in various studies. It also has a high negative predictive value (NPV) of 89%-92% and a positive predictive value (PPV) of 51%-52%. The yield of MRI fusion biopsy (MRI-FB) is similar, if not superior to MR cognitive biopsy. In-bore MRI-TB had better detection rates compared to MR cognitive biopsy, but were similar to MR fusion biopsy.
The use of MRI guidance in prostate biopsy is inevitable, subject to availability, cost, and experience. Any one of the three modalities (
MRI cognitive, MRI fusion and MRI in-bore approach) can be used. learn more MRI-FB has a fine balance with regards to accuracy, practicality and affordability.

However, the acceptance of this technique among urologists, even after the robotic approach, was reduced in the past years. Therefore, to overcome the challenges related to the single-port surgery, a new robotic platform named da Vinci SP was created with exclusive single port technology. We performed a non-systematic literature review regarding the single port technique in urologic surgeries since the first laparoscopic report until the da Vinci SP robotic platform. Three different periods were described (laparoscopy, robotic, and da Vinci SP), and we focused in our experience with this new single port robot. We selected different articles and summarized the information regarding the use of single-site surgery in laparoscopic procedures and the challenges of this approach. We also reported the experience of different groups using the single port robotic technique and some recent reports of the da Vinci SP approach. In our experience with this new console, we described some critical points related to our radical prostatectomy technique and the lessons learned during the introduction of this novel platform. Previous single-site procedures described some common challenges that limited the technique expansion. However, our experience with the da Vinci SP described feasible and safe procedures with acceptable intraoperative outcomes. The introduction of this platform is recent in the market, and the literature still lacks a high level of evidence describing the long-term outcomes of this new technology.Robot-assisted surgery has evolved over time. Radical nephrectomy with inferior vena cava thrombectomy is feasible and safe for level I, II and III thrombus in high volume centers. Though it is feasible for level IV thrombus, this procedure needs a multi-departmental co-operation. However, the safety of robot-assisted procedures in this subset is still unknown. Robot-assisted partial nephrectomy has been universally approved and found oncologically safe. Robotic adrenalectomy has been increasingly utilized for select cases, especially in bilateral tumors and for retroperitoneal adrenalectomy.
The robotic-assisted approach to simple prostatectomy (RASP) was conceived, essentially reproducing the fundaments of open simple prostatectomy. Since the first report, RASP underwent several technical modifications. The study aims to identify and describe the current robotic surgery techniques to approach benign prostatic hyperplasia (BPH).
The paper performed a non-systematic literature review accessing PubMed and Embase databases for all full-text articles published from 2008 to May 2020, assessing robot-assisted surgical techniques for BPH treatment using the terms "robot-assisted simple prostatectomy" OR "robotic simple prostatectomy" OR "RASP" AND "surgical technique".
After careful review of 180 studies in PubMed and 198 in Embase, 16 papers reporting different RASP techniques. After the first procedure described by Sotelo et al. [9], several authors contributed to the development of the RASP technique. John et al. [24] proposed the extraperitoneal access, and Yuh et al. [23] first reported the botic platforms until the new da Vinci Single Port.
To review the most used intracorporeal orthotopic ileal neobladder (ICONB) after radical cystectomy for bladder cancer and create a unified compendium of the different alternatives, including new consistent images.
We performed a non-systematic review of the literature with the keywords "bladder cancer", "urinary diversion", "radical cystectomy", and "neobladder".
Forty studies were included in the analysis. The most frequent type of ICONB was the modified Studer "U" neobladder (70%) followed by the Hautmann "W" modified neobladder (7.5%), the "Y" neobladder (5%), and the Padua neobladder (5%). The operative time to perform a urinary diversion ranged from 124 to 553 min. The total estimated blood loss ranged from 200 to 900 mL. The rate of positive surgical margins ranged from 0% to 8.1%. Early minor and major complication rates ranged from 0% to 100% and from 0% to 33%, respectively. Late minor and major complication rates ranged from 0% to 70% and from 0% to 25%, respectively.
The most frequent typetechnique. This manuscript represents a compendium of the most used ICONB with detailed descriptions of the technical aspects, operative and perioperative outcomes, and new consistent images of each technique.
