Abstract Introduction: Advances in vasectomy technique have minimized patient discomfort; however fear of pain remains a primary concern. The objective is to determine how the anticipation of pain associated with vasectomy compares with patient's actual intraoperative experienced pain levels.
Materials and methods: A cohort of patients undergoing clinic vasectomy was analyzed. Using visual analog pain scale patients were asked to rate their anticipated pain score (APS) pre-procedure and then an experienced pain score (EPS) post-procedure. Patients were also stratified by APS scores (high versus low). Changes in pain score were compared across these groups. Pain scores stratified by… More >

Abstract Introduction: To compare visual analog scale (VAS) pain scores between patients with a 2-minute versus 10-minute delay of peri-prostatic lidocaine injection prior to transrectal ultrasound-guided prostate biopsies (TRUS-bx).
Materials and methods: Eighty patients who underwent standard 12-core TRUS-bx by a single surgeon were prospectively randomized into four different treatment arms: bibasilar injection with a 2-minute delay, bibasilar injection plus a single apical injection with a 2-minute delay, bibasilar injection with a 10-minute delay, and bibasilar injection plus a single apical injection with a 10-minute delay. Patients were asked to report their level of pain on the VAS… More >

Abstract Introduction: To evaluate safety and excellent cosmetic outcome with laparoendoscopic single-site surgery (LESS). In this study, we compared the usefulness and efficacy of LESS versus conventional laparoscopic surgery for the treatment of urachal remnants.
Materials and methods: We retrospectively reviewed the medical records of 20 consecutive patients who underwent either conventional laparoscopic surgery or LESS from January 2007 to February 2015 at Kansai Medical University Hospital. Ten patients underwent surgery using the standard laparoscopic 3-port technique, and 10 patients underwent LESS. The patients included 12 males and 8 females (mean age, 24.5 years; range, 10-68 years). The… More >

Abstract Objective: As part of the American College of Cardiology Adult Congenital and Pediatric Cardiology Section effort to develop quality metrics (QMs) for ambulatory pediatric practice, the chest pain subcommittee aimed to develop QMs for evaluation of chest pain.
Design: A group of 8 pediatric cardiologists formulated candidate QMs in the areas of history, physical examination, and testing. Consensus candidate QMs were submitted to an expert panel for scoring by the RAND-UCLA modified Delphi process. Recommended QMs were then available for open comments from all members.
Patients: These QMs are intended for use in patients 5–18 years old, referred… More >

Abstract The purpose of this study was to explore the clinical efficacy and safety of posterior pedicle screw fixation in the treatment of thoracolumbar burst fracture. A total of 120 patients with thoracolumbar burst fractures were selected from January 2014 to December 2016. 60 patients were divided into the study group, and 60 patients were as the control group. The patients in the study group were treated with posterior pedicle screw fixation. The control group was treated with posterior non-traumatic pedicle screw fixation. After treatment, there were six months follow up. The clinical indexes, complications, and… More >

Abstract Psychological factors may play a role in the pathophysiology of chronic prostatitis/chronic pelvic pain syndrome (CP/ CPPS). This case series describes a cohort of 10 men presenting with CP/CPPS whose symptoms began after an extramarital sexual encounter, who strongly believed they had a sexually transmitted infection (STI) despite negative testing, and who have had no improvement with empiric antibiotic treatment. Patients’ clinical presentation and physical exam findings are reviewed. All men were clinically phenotyped with the UPOINT system. Pelvic floor spasm and not infection was prominent in these men. Treatment recommendations are proposed and compliance More >

Abstract Introduction: To evaluate the effect of physical activity on varicocele pain and how different varicocelectomy techniques relieve this pain.
Materials and methods: Between November 2012 and January 2015, a total of 64 patients with left groin pain and clinical varicocele were enrolled in this study. A visual analogue scale (VAS) classifying the pain in ten scores was used to assess the severity of pain before and after beginning continuous physical activity, and after operations. Patients were randomly divided into three groups. Group 1 had open sub-inguinal varicocelectomy, Group 2 had loupe-assisted sub-inguinal varicocelectomy and Group 3 had… More >

Abstract Introduction: Non-contrast CT (NCT) is commonly used to evaluate flank pain (FP). We sought to evaluate incidence of ureteral calculi on NCT in patients with FP, and to determine if clinical variables are associated with higher detection rates.
Materials and methods: Retrospective review identified 613 patients undergoing NCT for FP. Patient clinical data, NCT findings, and intervention were analyzed. Focus was placed on variables commonly associated with urolithiasis (V_stone), comprising hematuria, nausea/vomiting, and prior stone history. Statistical analysis was performed to identify risk of ureteral stones based on number and type of V_stone.
Results: No stone disease was identified… More >

Abstract Introduction: Chronic scrotal content pain (CSCP) is a common condition that can be challenging to manage definitively. A cohort of patients with CSCP have referred pain from myofascial abnormalities of the pelvic floor and therefore require treatment modalities that specifically address the pelvic floor such as pelvic floor physical therapy (PFPT).
Materials and methods: Retrospective chart review of all men with a pelvic floor component of CSCP presenting to our tertiary care medical center and undergoing PFPT from 2011-2014. Patients with CSCP and pain/tightness on pelvic floor evaluation with 360° digital rectal exam (DRE) were referred to… More >

Abstract A three-dimensional numerical simulation is conducted for a complex process in a laser-material system, which involves heat and mass transfer in a compressible gaseous phase and chemical reaction during laser irradiation on a urethane paint coated on a stainless steel substrate. A finite volume method (FVM) with a co-located grid mesh that discretizes the entire computational domain is employed to simulate the heating process. The results show that when the top surface of the paint reaches a threshold temperature of 560 K, the polyurethane starts to decompose through chemical reaction. As a result, combustion products CO₂, More >
