Background: It is generally perceived that minimally invasive nephroureterectomy (MINU), especially in the form of robotic-assisted laparoscopy, is gaining an increasing role in many institutions.

Objective: The aim of our study was to investigate contemporary trends in the adoption of MINU in the United States compared with open nephroureterectomy (ONU).

Methods: Patients who underwent ONU or MINU between 2011 and 2021 were retrospectively analyzed using PearlDiver Mariner, an all-payer insurance claims database.

Background: Penile prosthetic devices are the standard treatment for erectile dysfunction (ED) after failure of maximum medical therapy and conservative options. Several penile lengthening procedures (PLPs) can be performed concurrently with penile prosthesis (PP) insertion in patients with severe ED, penile shortening, and/or Peyronie's disease to help combat negative emotional and psychological concerns from penile length loss with penile prosthetic device placement.

Methods: An extensive, systematic literature review of the various pre-, intra-, and post-operative techniques that can be applied to preserve, restore or enhance penile length at the time of penile prosthetic implantation.

Objective: To analyze temporal trends and costs associated with the use of minimally invasive surgery (MIS) for kidney cancer in the US over the past decade. To examine the impact of social determinants of health (SDOH) on perioperative outcomes.

Methods: The PearlDiver Mariner, a national database of insurance billing records, was queried for this retrospective observational cohort analysis.

Purpose: Partial nephrectomies in the salvage setting after ablative or surgical therapy remain challenging cases that are underreported in the literature (1-5). The aim of this video is to demonstrate techniques for robotic salvage partial nephrectomy to manage recurrent renal cell carcinoma (RCC) after failed prior partial nephrectomy and primary cryotherapy.

Materials And Methods: A 55-year-old man after previous robotic-assisted right partial nephrectomy presented with a 2.

Background: The treatment paradigm for ureteropelvic junction obstruction (UPJO) has shifted towards minimally invasive pyeloplasty. A comparison Single Port (SP) and Multi Port (MP) robot-assisted pyeloplasty (RAP) was performed.

Methods: Data from consecutive patients undergoing SP RAP or MP RAP between January 2021 and September 2023 were collected and analysed.

Background: Aim of our study was to review the current evidence on single port robot-assisted radical prostatectomy (SP-RARP) and SP robot-assisted simple prostatectomy (SP-RASP) procedures.

Methods: A comprehensive bibliographic search on multiple databases was conducted in July 2023. Studies were included if they assessed patients with non-metastatic prostate cancer or candidate for benign prostatic hyperplasia surgery (P) who underwent SP-RARP or SP-RASP, respectively, (I), compared or not with other surgical techniques (C), evaluating perioperative, oncological, or functional outcomes (O).

Background: Recent literature on autologous breast reconstruction suggests that such factors as scar symmetry and skin paddle size impact patient preferences more than preservation of native breast skin. Since patient satisfaction with plastic surgery procedures can be largely influenced by beauty standards set by the general public, this study used a novel crowdsourcing method to evaluate laypeople's aesthetic preferences for different bilateral autologous breast reconstructions to determine the relative importance of scar and skin paddle symmetry and preservation of native skin.

Methods: Using Amazon's Mechanical Turk crowdsourcing marketplace, participants ranked images of reconstructions based on overall aesthetic appearance.

Robot-assisted surgery has emerged as a transformative technology, revolutionizing surgical approaches and techniques that decades ago could barely be imagined. The field of urology has taken charge in pioneering a new era of minimally invasive surgery with the ascent of robotic systems which offer enhanced visualization, precision, dexterity, and enabling surgeons to perform intricate maneuvers with improved accuracy. This has led to improved surgical outcomes, including reduced blood loss, lower complication rates, and faster patient recovery.

The gold standard treatment for non-metastatic upper tract urothelial cancer (UTUC) is represented by radical nephroureterectomy (RNU). The choice of surgical technique in performing UTUC surgery continues to depend on several factors, including the location and extent of the tumor, the patient's overall health, and very importantly, the surgeon's skill, experience, and preference. Although open and laparoscopic approaches are well-established treatments, evidence regarding robot-assisted radical nephroureterectomy (RANU) is growing.

Background: While implantation of an inflatable penile prosthesis (IPP) is commonly performed via infrapubic or penoscrotal approaches, the subcoronal (SC) approach for IPP implantation may safely and reliably allow for additional reconstructive procedures through a single incision.

Aim: The aim of this study is to report outcomes, including complications, of the SC approach and to determine common characteristics of patients undergoing the SC approach.

Methods: A retrospective chart review from May 11, 2012, to January 31, 2022, was performed at a single, tertiary care institution to identify patients with IPP implantation via the SC approach.

Monkeypox outbreaks were, until recently, mostly confined to Africa but a currently expanding worldwide outbreak has recently been designated a global emergency by the World Health Organization. Genital manifestation is common and can be confused with sexually transmitted infection (STI), posing a diagnostic challenge. We herein report a case of genital monkeypox superimposed on multiple co-incident STIs in a HIV patient and describe characteristic clinical findings and management.

Objective: To evaluate our initial experience with a multi-institutional workshop model of MRI/US fusion biopsy simulation for resident education.

Methods: Residents from 6 Chicago area urology programs participated in a MRI/US fusion biopsy workshop, which incorporated a 30 minute didactic session followed by hands-on simulation. The workshop was facilitated by fellowship-trained university faculty members and company representatives of MRI/US fusion technologies who provided teaching assistance and verbal feedback.
