Minimally invasive cytoreductive radical prostatectomy, exploring the safety and feasibility of a single-port or multi-port robotic platform.

Background: Consolidative resection or cytoreductive radical prostatectomy (CRP) may benefit men with non-organ confined prostate cancer. We report the safety, feasibility, and outcomes of robot-assisted laparoscopic CRP using a single-port (SP) or multi-port (MP) platform.

Methods: We reviewed consecutive men with clinical node positive or metastatic castrate-sensitive prostate cancer who underwent IRB-approved CRP and extended pelvic lymph node dissection using the da Vinci SP or MP Surgical Systems (Intuitive Surgical, Sunnyvale, CA) from 2015-2022.

Retrospective Concomitant Nonrandomized Comparison of "Touch" Cautery Versus Athermal Dissection of the Prostatic Vascular Pedicles and Neurovascular Bundles During Robot-assisted Radical Prostatectomy.

Background: During robotic-assisted radical prostatectomy (RARP), the use of electrocautery near the neurovascular bundles (NVBs) frequently results in thermal injury to the cavernous nerves. The cut and "touch" monopolar cautery technique has been suggested to reduce desiccating thermal injury caused by bipolar energy when vessels are sealed.

Objective: To compare potency outcomes between an athermal technique (AT) and touch cautery (TC) to transect the prostatic vascular pedicles (PVPs) and dissect the NVBs.

Crowd-Sourced Assessment of Surgical Skills of Urology Resident Applicants: Four-Year Experience.

Objective: To determine a) if surgical skills among urology resident applicants could be reliably assessed via crowdsourcing and b) to what extent surgical skills testing impacts resident selection.

Design: Interviewees completed the following surgical skills tasks during their interview day: open knot tying (OKT), laparoscopic peg transfer (LPT), and robotic suturing (RS). Urology faculty and crowd-workers evaluated each applicant's video-recorded performance using validated scoring and were assessed for agreement using Cronbach's alpha.

Pathological characteristics and prognostic indicators of different histopathological types of urinary bladder cancer following radical cystectomy in a large single-center Egyptian cohort.

Objective: To evaluate differences in pathological features and prognostics across four bladder cancer histopathological types: urothelial carcinoma (UC), urothelial carcinoma with variant histology (UCV), squamous cell carcinoma (SCC) and adenocarcinoma (ADC), utilizing a large cohort of radical cystectomy (RC) patients.

Methods: A retrospective analysis of patients who underwent RC at a single institution in Egypt between 1997 and 2004 was performed. Kaplan-Meier and multivariable analyses were performed to evaluate the prognostic significance of pathological features including tumor stage, grade, lymphovascular invasion (LVI), and lymph node (LN) involvement in the different subtypes on disease-free survival (DFS).

Skin-to-tumor Distance Predicts Treatment Failure of T1A Renal Cell Carcinoma Following Percutaneous Cryoablation.

Objective: To determine the impact of skin-to-tumor (STT) distance on the risk for treatment failure following percutaneous cryoablation (PCA).

Methods: We retrospectively reviewed patients who underwent PCA with documented T1a recurrent renal cell carcinoma (RCC) at 2 academic centers between 2005 and 2015. Patient demographics, tumor characteristics, and perioperative and postoperative course variables were collected.

Precise Characterization and 3-Dimensional Reconstruction of the Autonomic Nerve Distribution of the Human Ureter.

Purpose: We sought to characterize and 3-dimensionally reconstruct the distribution of the autonomic innervation of the human ureter.

Materials And Methods: Three male and 3 female pairs of ureters were evaluated at 2 mm serial transverse sections along the entire length of the ureter. The location of nerve tissue was immunohistochemically identified using the neuronal marker, S100 protein.

C-SATS: Assessing Surgical Skills Among Urology Residency Applicants.

Background: We hypothesized that surgical skills assessment could aid in the selection process of medical student applicants to a surgical program. Recently, crowdsourcing has been shown to provide an accurate assessment of surgical skills at all levels of training. We compared expert and crowd assessment of surgical tasks performed by resident applicants during their interview day at the urology program at the University of California, Irvine.

Minimally Invasive Hernia Repair in Robot-Assisted Radical Prostatectomy.

Inguinal hernia is a recognized complication of radical prostatectomy. Previous hernia repair, wound infection, midline incision, low body mass index, and preexisting or subclinical hernia contribute to the risk of inguinal hernia after radical prostatectomy. Concomitant hernia repair at the time of pelvic surgery has risks and benefits.

The challenges in the diagnosis of detrusor underactivity in clinical practice: A mini-review.

Objective: To review the current definitions, terminology, epidemiology and aetiology of detrusor underactivity (DU), with specific attention to the diagnostic criteria in use. In addition, we address the relation and the overlap between DU and bladder outlet obstruction (BOO). In this mini-review, we hope to help identify DU patients and facilitate structured clinical evaluation and research.

Minimally Invasive Hernia Repair in Robot-assisted Radical Prostatectomy.

Inguinal hernia is a recognized complication of radical prostatectomy. Previous hernia repair, wound infection, midline incision, low BMI, and preexisting or subclinical hernia contribute to the risk of inguinal hernia following radical prostatectomy.
