Zinner syndrome with contralateral hydronephrosis: A rare congenital condition.

Zinner Syndrome (ZS) is a rare congenital genitourinary abnormality defined by seminal vesicle cysts, ejaculatory duct obstruction, and unilateral renal dysplasia or agenesis. Patients can be asymptomatic, while others experience pain, urinary or ejaculatory symptoms and infertility. A patient that presented with painless gross hematuria was found to have a large pelvic cystic structure, an absent left kidney, multiple fluid collections in the region of the left seminal vesicle and right hydronephrosis.

Robot-Assisted Repair of Bladder Rupture following Penile Ring Entrapment.

Penile rings have been used to help sustain erection and enhance sexual pleasure for centuries. Constriction of the penis reduces the outflow of blood from the cavernosal tissue. However, if left for an extended time period, a condition called penile ring entrapment can occur.

Role of the androgen, estrogen, and progesterone receptors in adherent perinephric fat in robotic partial nephrectomy.

To determine whether androgen, estrogen, and/or progesterone signaling play a role in the pathophysiology of adherent perinephric fat (APF). We prospectively recruited patients undergoing robotic assisted partial nephrectomy during 2015-2017. The operating surgeon documented the presence or absence of APF.

Safety of retrograde pyelography for infected ureteral stones.

Introduction: Initial management of obstructing ureteral stones with concomitant urinary tract infection (UTI) includes prompt renal decompression and antibiotics. Some urologists theorize that performing retrograde pyelography (RGP) at the time of ureteral stent placement may cause pyelovenous backflow of bacteria thereby worsening clinical outcomes. We compared outcomes in patients with infected ureteral stones who underwent RGP versus no RGP prior to stent placement.

Comparing Off-clamp and On-clamp Robot-assisted Partial Nephrectomy: A Prospective Randomized Trial.

Objective: To determine whether performing robot-assisted partial nephrectomy without warm ischemia "off-clamp" results in favorable postoperative renal functional outcomes compared with the on-clamp method.

Methods: We conducted a prospective trial of 80 patients who underwent robot-assisted partial nephrectomy. They were randomized in a 1:1 ratio to undergo the procedure with renal artery clamping or without clamping.

The influence of visual and vestibular orientation cues in a clock reading task.

We investigated how performance in the real-life perceptual task of analog clock reading is influenced by the clock's orientation with respect to egocentric, gravitational, and visual-environmental reference frames. In Experiment 1, we designed a simple clock-reading task and found that observers' reaction time to correctly tell the time depends systematically on the clock's orientation. In Experiment 2, we dissociated egocentric from environmental reference frames by having participants sit upright or lie sideways while performing the task.

Development and Validity of a Silicone Renal Tumor Model for Robotic Partial Nephrectomy Training.

Objective: To provide a training tool to address the technical challenges of robot-assisted laparoscopic partial nephrectomy, we created silicone renal tumor models using 3-dimensional printed molds of a patient's kidney with a mass. In this study, we assessed the face, content, and construct validity of these models.

Materials And Methods: Surgeons of different training levels completed 4 simulations on silicone renal tumor models.

Off-clamp robot-assisted partial nephrectomy does not benefit short-term renal function: a matched cohort analysis.

In the interest of renal functional preservation, partial nephrectomy has supplanted radical nephrectomy as the preferred treatment for T1 renal masses. This procedure usually involves the induction of renal warm ischemia by clamping the hilar vessels prior to tumor excision. Performing robot-assisted partial nephrectomy (RAPN) "off-clamp" can theoretically prevent renal functional loss associated with warm ischemia.

Trends in the Management of Small Renal Masses: A Survey of Members of the Endourological Society.

Treatment modalities for small renal masses (SRMs) include open or minimally invasive radical or partial nephrectomy, and laparoscopic or percutaneous ablations. Members of the Endourological Society were surveyed to evaluate how practitioner and clinical practice characteristics may be associated with the management of SRMs over time. The survey assessed characteristics of urologists (recency of residency and fellowship training, clinical practice type and location, and treatment modalities available) and their management of SRMs over the past year and over the course of the year 5 years prior.

Retroperitoneal access for robotic renal surgery.

Introduction And Objective: Retroperitoneal access for robotic renal surgery is an effective alternative to the commonly used transperitoneal approach. We describe our contemporary experience and technique for attaining retroperitoneal access.

Materials And Methods: We outline our institutional approach to retroperitoneal access for the instruction of urologists at the beginning of the learning curve.

Diagnostic Utility of Selective Upper Tract Urinary Cytology: A Systematic Review and Meta-analysis of the Literature.

The diagnosis of upper tract urothelial carcinoma (UTUC) can be a challenging diagnostic pursuit. To date, there is no large-scale study assessing the statistical utility (eg, sensitivity and specificity) of selective cytology. Herein, we systematically reviewed and meta-analyzed the published literature to evaluate the efficacy of selective cytology for the detection of UTUC in patients with a suspicious clinical profile Selective cytology confers a high specificity but marginal sensitivity for the detection of UTUC.

Patient comorbidity predicts hospital length of stay after robot-assisted prostatectomy.

We sought to examine the impact of baseline patient characteristics and perioperative outcomes on postoperative hospital length of stay (LOS), following the robot-assisted radical prostatectomy (RARP). We retrospectively reviewed consecutive patients receiving RARP at our institution by two surgeons between January 2012 and March 2014 (n = 274). Baseline patient characteristics were collected, including Charlson comorbidity index (CCI).

Self-representation in social anxiety disorder: linguistic analysis of autobiographical narratives.

Cognitive models of social anxiety disorder (SAD) posit aberrant beliefs about the social self as a key psychological mechanism that maintains fear of negative evaluation in social and performance situations. Consequently, a distorted self-view should be evident when recalling painful autobiographical social memories, as reflected in linguistic expression, negative self-beliefs, and emotion and avoidance. To test this hypothesis, 42 adults diagnosed with SAD and 27 non-psychiatric healthy controls (HC) composed autobiographical narratives of distinct social anxiety related situations, generated negative self-beliefs (NSB), and provided emotion and avoidance ratings.
