    Biomarkers in patients treated with BCG: an update

    Julia Klap, Marianne Schmid, Kevin R. Loughlin
    Canadian Journal of Urology, Vol.21, No.4, pp. 7335-7343, 2014
    Abstract Introduction: Bacillus Calmette-Guérin (BCG) instillations are the recommended treatment for non-muscle invasive bladder cancer but high recurrence and progression rates remain after treatment. Despite patients risk stratification, BCG effectiveness remains unpredictable. A close, invasive and expensive follow up is mandatory. To improve or even replace this heavy surveillance in this high risk population, validated biomarkers were developed.
    Materials and methods: To identify the useful tools for the urologist in monitoring bladder cancer patients, we reviewed the literature focusing on plasma and urinary biomarkers of BCG-therapy outcome. Articles dated from 1988 to 2013 including specific keywords (urinary bladder… More >

    Prognostic value of postoperative urinary retention after male sling insertion

    Matthew Hall1, Allison Polland2, Steven Weissbart2, Stephen Mock3, Neil Grafstein2
    Canadian Journal of Urology, Vol.21, No.4, pp. 7344-7349, 2014
    Abstract Introduction: While urinary retention is a known complication of AdVance male sling (AMS) placement for post-prostatectomy incontinence (PPI), there is minimal data regarding ultimate continence outcomes for patients who experience this complication. The purpose of this study was to determine the rate of continence after AMS placement in patients who had postoperative urinary retention as compared with those patients who did not.
    Materials and methods: A retrospective review was conducted of patients who underwent AMS placement for PPI between 2008 and 2011 with postoperative void trial (TOV). Preoperative factors such as urodynamic findings, daily pad number (PPD)… More >

    Fiona Mei Wen Wu1, Melissa Hui Wen Tay1, Zhaojin Chen2, Bee Choo Tai3,4, Lincoln Guan Lim Tan1, Lata Raman1, Ho Yee Tiong1
    Canadian Journal of Urology, Vol.21, No.4, pp. 7351-7357, 2014
    Abstract Introduction: To compare baseline renal function and identify predictive factors in patients undergoing radical nephrectomy (RN) or donor nephrectomy (DN) and their risk of subsequent chronic kidney disease (CKD) after surgery.
    Materials and methods: A retrospective review of patients with no baseline CKD undergoing RN (n = 88) and DN (n = 58) from 2000 to 2008 was performed. Baseline and postoperative renal function (eGFR) was determined using the Modification of Diet in Renal Disease (MDRD) formula. CKD was defined as eGFR < 60 mL/min/1.73 m² according to the National Kidney Foundation guidelines.
    Results: Before surgery, patients undergoing… More >

    Overcoming the challenges of characterizing normal urodynamic parameters in middle-aged and older women

    Omer Gulpinar, Chasta Bacsu, Dominic Lee, Stephen Chiang, Alana Christie, Philippe Zimmern
    Canadian Journal of Urology, Vol.21, No.4, pp. 7358-7364, 2014
    Abstract Introduction: To describe urodynamic study (UDS) findings in middle-aged and older women with various lower urinary tract symptoms (LUTS) who were found to have a normal study interpretation.
    Materials and methods: Following institutional review board approval, UDS tracings of non-neurogenic women who were tested for various LUTS and whose study was interpreted as normal were reviewed. Demographic data, indications for UDS, and UDS parameter findings were extracted. UDS was conducted according to an established protocol using a 6F dual-lumen catheter (ICS guidelines) with a Laborie system and interpreted with a pre-existing template to standardize each reading.… More >

    Secondary pelvic congestion syndrome: description and radiographic diagnosis

    Andrew G. Winer1, Nicholas H. Chakiryan1, Ryan P. Mooney1, Daniel Verges1, Mazyar Ghanaat1, Atabak Allaeei2, Luke Robinson2, Harry Zinn2, Erich K. Lang1,2,3
    Canadian Journal of Urology, Vol.21, No.4, pp. 7365-7368, 2014
    Abstract Introduction: Pelvic congestion syndrome (PCS) is a complex condition of the pelvic venous system leading to nonspecific pelvic pain that was initially described in females alone. The underlying abnormalities, though diverse, all result in increased pressure in the left gonadal vein which is transmitted retrograde into the pelvic venous system. Our primary aim was to describe our findings of secondary PCS as a distinct entity from primary PCS in that it has an identifiable vascular etiology and is gender nonspecific. We also aimed to assess the adequacy of late-arterial phase CT urography (CTU) as the initial… More >

    Critical analysis of 30 day complications following radical nephroureterectomy for upper tract urothelial carcinoma

    Yu-Kuan Lin, Amanda Deliere, Kathleen Lehman, Lewis E. Harpster, Matthew G. Kaag, Jay D. Raman
    Canadian Journal of Urology, Vol.21, No.4, pp. 7369-7373, 2014
    Abstract Introduction: Patients with upper tract urothelial carcinoma (UTUC) are often elderly and comorbid owing to associated risk factors for developing this malignancy. Perioperative complications may be significant in such a surgical population. We define the incidence and risk factors associated with perioperative complications occurring within 30 days of radical nephroureterectomy (RNU).
    Materials and methods: Medical records of 92 consecutive patients undergoing RNU were reviewed. Complications occurring within 30 days of surgery were graded using the modified Clavien-Dindo classification. The number, severity, and type of complications were recorded. Minor complications were classified as Clavien II or less, while… More >

    Grading variability of urothelial carcinoma: experience from a single academic medical center

    Eugene W. Lee1, Fang-Ming Deng2, Jonathan Melamed2, Savvas Mendrinos2, Kasturi Das2, Tsivia Hochman3, Samir S. Taneja1, William C. Huang1
    Canadian Journal of Urology, Vol.21, No.4, pp. 7374-7378, 2014
    Abstract Introduction: Tumor grade plays a critical role in the management of papillary non-invasive urothelial carcinoma (UC). Since grading of UC relies on morphologic criteria, variability in interpretation exists among pathologists. The objective of this study was to examine inter-observer variability in the grading of papillary non-invasive UC at a single academic medical center.
    Materials and methods: One general pathologist and two genitourinary pathologists were blinded to patient identity and graded 98 consecutive UC specimens using the 1973 and 2004 classification systems. Kappa statistics (κ) were used to measure inter-observer reproducibility to account for agreement expected purely by… More >

    Ricardo A. Rendon1, Ross J. Mason1, Susan Kirkland2, Joseph G. Lawen1, Mohamed Abdolell3
    Canadian Journal of Urology, Vol.21, No.4, pp. 7379-7384, 2014
    Abstract Introduction: To develop a classification tree for the preoperative prediction of benign versus malignant disease in patients with small renal masses.
    Materials and methods: This is a retrospective study including 395 consecutive patients who underwent surgical treatment for a renal mass < 5 cm in maximum diameter between July 1st 2001 and June 30th 2010. A classification tree to predict the risk of having a benign renal mass preoperatively was developed using recursive partitioning analysis for repeated measures outcomes. Age, sex, volume on preoperative imaging, tumor location (central/peripheral), degree of endophytic component (1%–100%), and tumor axis position… More >

    Modifier 22 on perioperative outcomes of robotic assisted laparoscopic prostatectomy

    Katie S. Murray1, Joshua Griffin1, Yuan Feng2, Moben Mirza1, J. Brantley Thrasher1,3, Ernesto Lopez-Corona3, David A. Duchene1,3
    Canadian Journal of Urology, Vol.21, No.4, pp. 7385-7389, 2014
    Abstract Introduction: Robotic assisted laparoscopic prostatectomy (RALP) is a mainstay in the treatment of prostate cancer. Current procedure terminology (CPT) identifies a case that requires substantially greater effort than usual by using the modifier 22 code (M22). Our objective was to identify the most common etiologies leading to M22 at our institution and determine the effect on perioperative outcomes.
    Materials and methods: We retrospectively reviewed our prostatectomy database from 2009–2012 to identify patients who underwent RALP with and without M22. Reasons for M22 were determined by review of operative reports. Comparisons were made using Chi-square analysis and independent… More >

    Percutaneous cryoablation of a renal cell carcinoma in a transplanted kidney

    Tommaso Silvestri1, Fulvio Stacul2, Michele Bertolotto3, Mary Artero4, Salvatore Siracusano1
    Canadian Journal of Urology, Vol.21, No.4, pp. 7390-7392, 2014
    Abstract In patients who underwent renal transplantation, urinary tract tumors have an incidence of approximately 1.5%-3.3%. We report a rare case of renal cell carcinoma occurring in a transplanted kidney 25 years after the transplant. The lesion was treated by CT-guided percutaneous cryoablation with the ablation of renal lesion. This approach offers more accuracy compared with ultrasonography (US), and it is faster compared to magnetic resonance (MR) guidance. In transplanted kidneys, CT-guided cryoablation seems to be safe.

    Primary osteosarcoma in a bladder diverticulum

    Rami R. Abou Ghaida, Ragheed M. Saoud, Mohammad Bulbul
    Canadian Journal of Urology, Vol.21, No.4, pp. 7393-7395, 2014
    Abstract Osteosarcoma is a highly malignant soft tissue tumor. Bladder extra-skeletal osteosarcomas are very rare, and only few cases are reported in the English medical literature. This case is the third one of its kind to be reported consisting of a bladder diverticulum osteosarcoma. Compared to urothelial bladder carcinoma, urinary bladder osteosarcomas have a poorer prognosis. Biopsy and immunochemical staining are critical for the diagnosis. Treatment regimens vary based on the stage of the disease. However, choosing the best option for treatment is still unclear, due to the scarcity of cases available. More >

    Physical examination of the epididymis made easy: a novel, reproducible and structured approach

    Andrew Di Pierdomenico, Darren Beiko
    Canadian Journal of Urology, Vol.21, No.4, pp. 7396-7398, 2014
    Abstract The epididymis is the most common source of acute and chronic scrotal pain in the outpatient setting, yet there are no standardized methods for proper palpation of this organ. We describe a novel scrotal examination technique that is reproducible and easy to learn. Our technique utilizes a maneuver we call testicular ‘framing’, and in our experience this maneuver almost invariably leads to proper diagnosis of epididymal pathology by facilitating successful palpation of the epididymal head, body and tail.

    How I Do It: Managing bone health in patients with prostate cancer

    Jack Barkin
    Canadian Journal of Urology, Vol.21, No.4, pp. 7399-7403, 2014
    Abstract Urologists have two scenarios where they have to address bone loss or increased risk of fractures in men with prostate cancer. In the first setting, a patient who has been started on androgen deprivation therapy may develop cancer-treatment-induced bone loss. In the second setting, a patient’s prostate cancer may have metastasized to the bone. This article describes six steps to manage bone health in patients diagnosed with prostate cancer in a community practice. More >
