    E. David Crawford1, Daniel P. Petrylak2, Celestia S. Higano3, Adam S. Kibel4, Philip W. Kantoff5, Eric J. Small6, Neal D. Shore7, Anna Ferrari8
    Canadian Journal of Urology, Vol.22, No.6, pp. 8048-8055, 2015
    Abstract Introduction: Numerous treatments are approved for metastatic castration-resistant prostate cancer (mCRPC), including sipuleucel-T, an FDA-approved immunotherapy.
    Materials and methods: In this paper we review recent data providing insights into the mechanism of action of sipuleucel-T which suggests sipuleucel-T may be most effective when administered to mCRPC patients with a low burden of disease. Published and presented data from the sipuleucel-T clinical trials NeoACT (NCT00715104), IMPACT (NCT00065442), ProACT (NCT00715078), PROTECT (NCT00779402), OpenACT (NCT00901342), STAMP (NCT01487863) and STAND (NCT01431391), individually or across trials, were included in this review.
    Results: Overall, a growing body of evidence supports the concept that sipuleucel-T,… More >

    Prostate cancer after initial high-grade prostatic intraepithelial neoplasia and benign prostate biopsy

    Premal Patel1, Jasmir G. Nayak1,2, Zlatica Biljetina4, Bryan Donnelly3, Kiril Trpkov4
    Canadian Journal of Urology, Vol.22, No.6, pp. 8056-8062, 2015
    Abstract Introduction: Limited data exist on long term pathological outcomes in patients with initial prostate biopsies showing either high-grade intraepithelial neoplasia (HGPIN) or benign findings, who are subsequently diagnosed with prostate cancer.
    Materials and methods: Preoperative characteristics of patients showing either HGPIN or benign initial prostate biopsies were investigated and compared in patients with and without a subsequent diagnosis of prostate cancer. We also compared the biopsy and prostatectomy findings in patients with prostate cancer in both groups.
    Results: We evaluated 161 and 85 patients with initial HGPIN and benign prostate biopsies, respectively, who underwent a subsequent biopsy. After… More >

    Zachary L. Smith1, Eugene J. Pietzak1, Chelsey K. Meise2, Keith Van Arsdalen1, Alan J. Wein1, S. Bruce Malkowicz1, Thomas J. Guzzo1
    Canadian Journal of Urology, Vol.22, No.6, pp. 8069-8073, 2015
    Abstract Introduction: The Fuhrman grading system (FGS) is the most widely utilized pathological classification and predictor of renal cell carcinoma (RCC) prognosis. The aim of this study was to test the prognostic ability of a simplified two-tier FGS.
    Materials and methods: We reviewed the data of 509 patients with clear cell RCC who underwent radical or partial nephrectomy between January 1994 and April 2007. The conventional four-tier (I, II, III, IV) FGS was compared to a simplified two-tier FGS in which grades I and II were combined (low grade) and grades III and IV were combined (high grade).… More >

    Robotic-assisted laparoscopic catheterizable bladder augment: a novel approach to treat recurrent bladder neck contracture following radical prostatectomy

    Joseph Wagner, Peter Haddock
    Canadian Journal of Urology, Vol.22, No.6, pp. 8074-8078, 2015
    Abstract Introduction: Bladder neck contractures (BNC) are an uncommon complication following radical prostatectomy. Occasionally, BNCs can be refractory to endoscopic approaches. We describe the effectiveness of a novel robotic-assisted laparoscopic catheterizable bladder augment in treating recalcitrant BNCs.
    Materials and methods: Patients undergoing robotic-assisted radical prostatectomy (RALP) between 2004-2014 who developed a postoperative BNC were identified. We documented our experience with robotic-assisted laparoscopic catheterizable bladder augment for recalcitrant BNCs. Total operative time, robotic time, estimated surgical blood, length of hospital stay, serum creatinine, complications, and postoperative course/upper tract imaging were recorded.
    Results: Thirty-six of 2002 RALP patients (1.8%) experienced a… More >

    Outcomes of surgical treatment of ureteral strictures after laser ureterolithotripsy for impacted stones

    Victor Srougi, Guilherme P. Padovani, Giovanni S. Marchini, Fabio C. Vicentini, Eduardo Mazzucchi, Miguel Srougi
    Canadian Journal of Urology, Vol.22, No.6, pp. 8079-8084, 2015
    Abstract Introduction: To evaluate the outcomes of ureteral strictures treatment after endoureterotomy using the holmium laser or open/laparoscopic surgery.
    Material and methods: From a database of 1101 patients that underwent semi-rigid holmium laser ureterolithotripsy from 2003 to 2013, we performed a search for patients treated for ureteral stricture. Parameters analyzed included patient demographic, stone burden, and ureteral stricture characteristics. Treatment included holmium laser endoureterotomy for stenosis ≤1 cm and open/laparoscopic repair for stenosis >1 cm or for failed endoscopic treatment. Outcomes and complications were assessed. Success was defined as symptom improvement and radiographic obstruction resolution.
    Results: Of all the… More >

    Canadian Journal of Urology, Vol.22, No.6, pp. 8085-8092, 2015
    Abstract Introduction: To investigate the association of C-reactive protein (CRP), a marker of systemic inflammation, with renal functional decline in patients undergoing partial nephrectomy (PN) for renal mass.
    Materials and methods: Retrospective study of patients who underwent PN between February 2006-March 2011, with ≥6 months follow-up. Data was analyzed between two groups: CRP increase ≥0.5 mg/L from 6 months postoperative ("CRP rise," CRPR) versus no CRP increase ≥0.5 ("CRP stable," CRPS). Primary outcome was change in estimated glomerular filtration rate (ΔeGFR, mL/min/1.73 m²), with de novo postoperative stage III chronic kidney disease (stage III-CKD, eGFR <60 mL/min/1.73 m²)… More >

    Manual bladder washouts for urinary clot retention: a survey of knowledge among healthcare workers

    Murtaza Dungerwalla1, Nicholas Davies2, Marlon Perera1, Nathan Papa1, Nathan Lawrentschuk1,3,4
    Canadian Journal of Urology, Vol.22, No.6, pp. 8093-8098, 2015
    Abstract Introduction: Manual bladder washouts (MBWs) are an integral skill for healthcare workers dealing with urological patients. Despite this they are often overlooked by educators and omitted from formal teaching curricula. We aimed to determine the level of competence and training among healthcare workers in performing a MBW.
    Materials and methods: Following a literature review for correct MBW technique, a 15-question survey was developed to assess knowledge and self-reported competency of doctors and nurses in performing a MBW. Two hundred paper and email-based surveys were distributed to doctors and nurses in the urology wards of Australian public and… More >

    Tim A. Ludwig1,*, Philip Reiss1,*, Marco Wieland2, Andreas Becker1, Margit Fisch1, Felix K. Chun1, Roland Dahlem1
    Canadian Journal of Urology, Vol.22, No.6, pp. 8100-8104, 2015
    Abstract Introduction: The aim was to perform a feasibility study of the new artificial sphincter device ARTUS in human cadavers. ARTUS is a new electro-mechanical device, which may prevent urethral damage due to a new working principle which is to perform only sequential pressure on successive parts of the urethra.
    Material and methods: The implantation of the ARTUS device was performed in six cadavers (3 males, 3 females) with different body mass indices. Subsequently the basic operation data (operation time, cuff size, length of wires, complication) were assessed.
    Results: The implantation of the ARTUS device is performed easily by… More >

    Retroperitoneal hematoma secondary to inferior adrenal artery spontaneous hemorrhage

    Andrew J. Davidiuk, David D. Thiel
    Canadian Journal of Urology, Vol.22, No.6, pp. 8105-8107, 2015
    Abstract Spontaneous retroperitoneal hematoma (SRH) is a rare, potentially lethal entity that can arise from a variety of etiologies. We present a case of SRH secondary to hemorrhage from the right inferior adrenal artery in a 22-year-old woman. The patient presented to the emergency room with significant right flank pain, and computed tomography (CT) demonstrated a large, right-sided retroperitoneal hematoma with no identifiable etiology. Renal angiography revealed active extravasation from the right inferior adrenal artery. The patient was definitively treated with endovascular coiling of the ruptured artery, and long-term follow-up demonstrated resolution of the retroperitoneal hematoma. More >

    A case of Fournier’s gangrene necessitating total penectomy

    Shuvro De, Michael J. Belsante, Timothy J. Tausch, Jay Simhan
    Canadian Journal of Urology, Vol.22, No.6, pp. 8108-8111, 2015
    Abstract Fournier’s gangrene is an uncommon necrotizing infection affecting the genital and perineal area. Penile involvement in particular is rare owing to its rich vascular supply. In this report, we document a case of Fournier’s gangrene involving penile and urethral tissue requiring multiple debridements resulting in significant penile deformity and a non-healing wound. Eventually, the patient underwent penectomy and perineal urethrostomy creation. In this case, penectomy and perineal urethrostomy provide a functional outcome for highly refractory and complex patients with Fournier’s gangrene involving penile tissue. More >
