Developing a Diagnostic Multivariable Prediction Model for Urinary Tract Cancer in Patients Referred with Haematuria: Results from the IDENTIFY Collaborative Study.

Background: Patient factors associated with urinary tract cancer can be used to risk stratify patients referred with haematuria, prioritising those with a higher risk of cancer for prompt investigation.

Objective: To develop a prediction model for urinary tract cancer in patients referred with haematuria.

Design, Setting, And Participants: A prospective observational study was conducted in 10 282 patients from 110 hospitals across 26 countries, aged ≥16 yr and referred to secondary care with haematuria.

Workforce Characteristics in Urology.

Introduction: In this study we holistically describe and characterize the current state of urology practice by evaluating compensation, workload and practice factors as they relate to our demographic makeup as a specialty.

Methods: We collaborated with the American Urological Association to query its domestic membership of practicing urologists regarding socioeconomic, workforce and quality of life issues. The survey consisted of 26 questions and took approximately 13 minutes to complete.

Urological Survivorship Issues Among Adolescent Boys and Young Men Who Are Cancer Survivors.

Background: Urological survivorship issues encompass an area that may potentially be overlooked after treatment of childhood cancer in adolescent boys and young men. Side effects of cancer therapy may include subsequent development of erectile dysfunction (ED), hypogonadism, and infertility in adulthood.

Aim: The purpose of this review is to focus on the etiology and prevalence of the range of sexual and gonadal dysfunction in adolescent boys and young men who are cancer survivors, while discussing current recommendations for evaluation and treatment.

Sacral neuromodulation in overactive bladder: a review and current perspectives.

Overactive bladder (OAB) symptoms of urgency, frequency, and urge incontinence currently affect a substantial portion of the population, especially as age increases. Sacral neuromodulation has become a popular option for refractory OAB symptoms over the past 2 decades. Studies have demonstrated that it is an effective treatment for OAB and urge incontinence as indicated by decreased number of voids, increased bladder capacity, and fewer leakage events.

Do Overweight and Obese Pediatric Stone Formers Have Differences in Metabolic Abnormalities Compared With Normal-weight Stone Formers?

Objective: To determine if 24-hour urinary parameters in children with nephrolithiasis across 4 institutions were influenced by body mass index (BMI).

Materials And Methods: The 24-hour urinary parameters obtained from children with nephrolithiasis between 2000 and 2013 were stratified by BMI percentile ≥85th and <85th (overweight and obese patients vs healthy weight, respectively). A total of 206 children were included in the study.

National multi-institutional cooperative on urolithiasis in children: Age is a significant predictor of urine abnormalities.

Introduction: Pediatric nephrolithiasis is a growing problem and prior studies have shown the greatest increase in nephrolithiasis in the adolescent population. Metabolic abnormalities have historically been cited as the primary cause of pediatric nephrolithiasis; however, dietary and other factors such as obesity have also been studied with mixed results.

Objective: We reviewed the charts of pediatric patients with a history of nephrolithiasis to determine the number and types of metabolic abnormalities present on 24-h urine analysis.

Laparoscopic percutaneous inguinal hernia repair in children: review of technique and comparison with open surgery.

Introduction: Minimally-invasive approaches for inguinal hernia repair have evolved from conventional laparoscopy requiring placement of three ports and intracorporeal suturing to simple, one and two port extraperitoneal closure techniques. We utilize a single port laparoscopic percutaneous repair (LPHR) technique for selected children requiring operative intervention for inguinal hernia. We suspect that compared to open surgery, LPHR offers shorter operative duration with comparable safety and efficacy.

Patient positioning and prevention of injuries in patients undergoing laparoscopic and robot-assisted urologic procedures.

Positioning injuries in the perioperative period are one of the inherent risks of surgery, but particularly in robot-assisted urologic surgery, and can result in often unrecognized morbidity. Injuries such as upper or lower extremity peripheral neuropathies occur via neural mechanisms and injuries such as compartment syndrome, rhabdomyolysis, ischemic optic neuropathy, and acute arterial occlusion occur via vascular mechanisms. The risk of injury may be exacerbated by operative and patient-related risk factors.
