To identify factors affecting potency and to predict ideal patient subgroups who will have the highest chance of being potent after robot-assisted laparoscopic prostatectomy (RALP) based on nerve sparing (NS). Analysis of 7268 patients who underwent RALP between 2008 and 2018 with a minimum of 12 months of follow-up was performed. The patients were then categorized into four separate neurovascular bundle-sparing groups (NVB 1-4).

Müllerianosis of the urinary bladder is an extremely rare, benign condition defined by the presence of at least two of the three müllerian-derived components (endosalpinx, endometrium, and endocervix) in the lamina propria and muscularis propria of the urinary bladder. It frequently mimics neoplastic condition, either malignant or benign. Here, we present a case of cystic müllerianosis of urinary bladder, which was clinically thought to be a urinary bladder neoplasm.

Purpose: Prediction of potency recovery following robot-assisted radical prostatectomy (RARP) is useful for better patient counseling and postoperative treatment strategies. In this study we propose a preoperative and postoperative nomogram to predict postoperative potency recovery following RARP.

Materials And Methods: Patients from development set (6,502) were selected to develop the nomograms, and patients in validation set (2,706) were used for validation.

Objective: 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.

Materials And Methods: 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".

Different groups described the single-port surgery since its first report in laparoscopic procedures. 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.

Background: Early recovery of continence and potency after robotic-assisted laparoscopic prostatectomy (RALP) still remains a challenge.

Objective: To assess the effect of our modified apical dissection and lateral prostatic fascia preservation (mod-RALP) technique on early functional outcomes.

Design, Setting, And Participants: Among 2168 patients who underwent RALP between 2017 and 2019, 104 received a mod-RALP, and for the purposes of this study they were propensity score (PS) matched with a control group of conventional RALP cases based on preoperative and histological characteristics.

Objective: To assess the influence of the 2012 US Preventive Services Task Force (USPSTF) recommendation against prostate-specific antigen (PSA)-based screening on oncological and functional outcomes following robot-assisted laparoscopic prostatectomy (RALP).

Materials And Methods: We retrospectively analysed patients who underwent RALP between 2008 and 2018 with a minimum of 12-month follow-up from a prospectively collected institutional review board-approved database. The impact of the USPSTF recommendation against PSA screening on our surgical outcomes was assessed using a logistic regression model using two groups comprising patients treated before/after the USPSTF statement and indicating time trends for each successive year.

Robotic radical prostatectomy (RARP) is a standardized treatment for localized prostate cancer, which provides better functional outcomes and similar oncological outcomes compared to open approaches. Here, we share our experience of 12,000 RARPs by describing the outcomes of the procedure in terms of positive surgical margin (PSM), continence, and potency as well as by presenting our detailed surgical technique with recent modifications. On cancer control, the PSM rates were 5.

Pelvic lymph node dissection (pLND) is considered the most reliable method for the detection of lymph node metastases in prostate cancer. Current clinical guidelines recommend performing pLND in intermediate- and high-risk patients that are defined using different clinical nomograms and different cut-off values. Although the detection of lymph node metastatic disease can identify patients who could benefit from adjuvant therapies and potentially improve prostate cancer-related survival outcomes, so far there has been no level 1 evidence to support this survival benefit.

Simple prostatectomy is an option for management of patients with enlarged prostates and obstructive symptoms. However, the guidelines still do not state a gold-standard treatment for men with BPH and some of these patients with BPH are also known to harbor prostate cancer. This issue can be a challenge because, in the traditional simple prostatectomy, the prostate capsule is often left in place, and that is usually the area of the prostate cancers.
