INTRODUCTION: Urology residency training in Canada is quickly evolving from a time-based to a competency-based model. We aim to better define core surgical competencies that would comprise a surgical curriculum and assess any discrepancies in opinion nationally. METHODS: A web-based survey was validated and sent to the 536 practicing members of the Canadian Urological Association (CUA) in August and October 2014. The survey consisted of questions regarding practice demographics, fellowship training, and evaluated the 76 most common urological procedures (using a five-point Likert scale) in the context of the question, "After completion of residency training in Canada a urologist should be proficient in…" A core procedure was defined as one for which there was ≥75% agreement...

INTRODUCTION AND HYPOTHESIS: Fournier's gangrene is a rare, necrotising fasciitis of the external genitalia, perineal or perianal regions. The disease has a higher incidence in males and risk factors for development include diabetes, HIV, alcoholism and other immune-compromised states. The aggressive disease process is associated with a high mortality rate of 20-30%. In addition, the increasing age and prevalence of diabetes in the population, begs the need for increased clinical awareness of Fournier's gangrene with emphasis on early diagnosis and management...

Recent studies have suggested that multiparametric magnetic resonance imaging (MRI)/ultrasound (US) fusion-guided prostate biopsy can detect more clinically significant prostate cancers, which could impact patient management. As many of the studies evaluating MRI/US fusion-guided prostate biopsy were conducted in specialized quaternary care centers, the question remains whether this technology is transferable to general practice. Our study assesses the diagnostic ability of MRI/US fusion-guided prostate biopsy compared with standard biopsy in the new era of prostate cancer Grade Grouping...

In the WHO Classification of Tumours of the Urinary System and Male Genital Organs published in 2016, it was officially recommended that the percent of Gleason pattern 4 (GP4) be reported on pathology reports to better reflect the extent in Gleason score 7 tumors. In this study we assessed the reproducibility of reporting GP4 on prostate biopsies. We analyzed prospectively 422 cores containing GP4 from our consult cases over a period of 2.5 months. The percent pattern 4 was assigned to all the cases in 10% increments from 0% to 100% (with the addition of 5%) by 1 of 4 fellows in urological pathology and by the expert urological pathologist...

Botulinum neurotoxin A (BoNT-A), derived from Clostridium botulinum, has been used clinically for several diseases or syndrome including chronic migraine, spasticity, focal dystonia and other neuropathic pain. Chronic pelvic or bladder pain is the one of the core symptoms of bladder pain syndrome/interstitial cystitis (BPS/IC). However, in the field of urology, chronic bladder or pelvic pain is often difficult to eradicate by oral medications or bladder instillation therapy. We are looking for new treatment modality to improve bladder pain or associated urinary symptoms such as frequency and urgency for patients with BPS/IC...

OBJECTIVE: Perioperative inadvertent hypothermia (PIH) (core body temperature to < 36 °C) is a common event during surgery. PIH may result from multiple factors. Elderly urology patients are at greater risk than other patients for hypothermia. PIH may cause adverse postoperative cardiac clinical manifestations. Our study aimed to determine the effects of postoperative alteration of core body temperature on the ECG parameters in patients undergoing transurethral resection. PATIENTS AND METHODS: Fifty-nine patients, 40-83 years of age, who were scheduled for elective Transurethral Resection Prostate and/or Bladder (TUR-P and/or TUR-B) were enrolled in the study...

Renal mass biopsy is increasingly used to guide conservative tumor management, placing increasing importance on pathologists' ability to diagnose small tumor samples. A 66-year-old man with a history of prior splenectomy for trauma presented for urologic evaluation after identification of a left 5.8 cm renal mass. Partial envelopment of the mass by renal parenchyma and equivocal enhancement on computed tomography raised concern for renal cell carcinoma. Needle-core biopsy revealed blood, subtle vasculature, few aggregates of lymphocytes, and rare renal tubules...

Since its initial description in 1966 by Dr Donald Gleason, Gleason grading has become the cornerstone in the management of prostate cancer (PCa). With widespread use of Prostate Specific Antigen (PSA) screening and needle core biopsy, the diagnosis and management of PCa have dramatically evolved. In addition, better understanding of the morphological spectrum of prostate cancer and its clinical significance have prompted the refinement of the grading criteria and reporting guidelines commensurate to contemporary practice...
