Management of adult concealed penis using a meshed, split-thickness skin graft.

Introduction: Concealed penis (CP) is a rare problem faced by urologists and plastic surgeons. CP occurs secondary to trauma, obesity, or infection. Surgical treatment is individualized and based on patient and provider variables.

Accelerometer Measurement of Head Movement During Laparoscopic Surgery as a Tool to Evaluate Skill Development of Surgeons.

Objective: To detect and measure surgeons' head movement during laparoscopic simulator performance to determine whether expert surgeons have economy of motion in their head movement, including change of direction, compared with intermediate and novice surgeons. We investigated head movement as an objective tool for assessment of laparoscopic surgical skill and its potential use for assessing novice surgeons' progress on the learning curve.

Design: After obtaining institutional review board approval, medical students, urology residents, and attending staff surgeons from an academic institution were recruited.

A Rationale to Use Bladder Boari Flap Reconstruction for Late Kidney Transplant Ureteral Strictures.

Objective: To evaluate the efficacy of Boari flap reconstruction (BFR) in the management of late-onset transplant ureteral strictures (TUS).

Methods: Between March 2007 and March 2014, there were 730 patients who underwent kidney transplant (KTx) at our institution. We identified 16 patients with TUS, occurring more than 60 days after KTx.

Crowdsourcing Assessment of Surgeon Dissection of Renal Artery and Vein During Robotic Partial Nephrectomy: A Novel Approach for Quantitative Assessment of Surgical Performance.

Introduction: We sought to describe a methodology of crowdsourcing for obtaining quantitative performance ratings of surgeons performing renal artery and vein dissection of robotic partial nephrectomy (RPN). We sought to compare assessment of technical performance obtained from the crowdsourcers with that of surgical content experts (CE). Our hypothesis is that the crowd can score performances of renal hilar dissection comparably to surgical CE using the Global Evaluative Assessment of Robotic Skills (GEARS).

Electroencephalographic Monitoring of Brain Wave Activity During Laparoscopic Surgical Simulation to Measure Surgeon Concentration and Stress: Can the Student Become the Master?

Purpose: To measure gamma and alpha brain wave activity as a measurement of concentration and stress levels during surgical simulator performance of laparoscopic tasks to determine if expert surgeons have different brain activity patterns compared with intermediate and novice surgeons.

Materials And Methods: After obtaining Institutional Review Board approval, 1st and 2nd year medical students, urology residents (PGY2-PGY5), and attending urologists from one institution were recruited. Participants were stratified by level of experience and performed laparoscopic tasks on the EDGE laparoscopic simulator.

Comparison of infrapubic versus transcrotal approaches for inflatable penile prosthesis placement: a multi-institution report.

Inflatable penile prostheses (IPP) are associated with excellent long-term outcomes. To date, no study has evaluated the significance of surgical approach on IPP intraoperative variables. High-volume surgeons placing the Titan 0-degree prosthesis from March-July 2012 completed questionnaires including pre-/intraoperative variables.

Robotic partial nephrectomy for clinical stage T1b tumors: intermediate oncologic and functional outcomes.

Objective: The objective of this study was to examine our intermediate oncologic and functional outcomes of robotic partial nephrectomy for clinical T1b tumors. Partial nephrectomy has become the gold standard of treatment for small renal masses. Recently, indications for minimally invasive partial nephrectomy have extended to larger and more complicated renal masses in some centers.

Activation of autophagy in mesenchymal stem cells provides tumor stromal support.

Recent studies have implicated multipotential mesenchymal stem cells (MSCs) as an aid to breast cancer cell proliferation and metastasis, partly as a result of the MSCs secretome. As the tumor gets beyond 2 mm in diameter, the stromal cells could undergo starvation due to the lack of sufficient nutrients in solid tumor microenvironment. In this study, we investigated the survival mechanisms used by stressed stromal cells in breast cancers.

Does a replacement or revision of an inflatable penile prosthesis lead to decreased patient satisfaction?

To analyze the reason for replacement, revision and overall satisfaction of a cohort who underwent surgical replacement of an inflatable penile prosthesis (IPP). A cohort of 105 patients who underwent IPP replacement from 2005-2007 was retrieved from the prosthesis database. Approximately 21.
