    Ureteral diverticulum: a review of the current literature

    Louise C. McLoughlin, Niall F. Davis, Catherine Dowling, Molly P. Eng, Richard E. Power
    Canadian Journal of Urology, Vol.20, No.5, pp. 6893-6896, 2013
    Abstract Introduction: Ureteral diverticulum is a rare urological condition with only 45 cases described in the literature. These previously reported cases vary in their presentation, diagnosis and management and there is no consensus in the literature on the best diagnostic tool available. We describe our experience on diagnosing and managing this condition in two patients and provide a descriptive review of the current literature on ureteral diverticulum.
    Materials and methods: A Medline search was performed to identify all reported cases of ureteral diverticulum. Key words used were: ureteral diverticulum; abortive bifid ureter; congenital diverticulum; acquired diverticulum. We also… More >

    Priya N. Werahera1,2, E. David Crawford3, Francisco G. La Rosa1, Kathleen C. Torkko1, Beth Schulte4, Holly T. Sullivan1, Adrie van Bokhoven1, M. Scott Lucia1, Fernando J. Kim4
    Canadian Journal of Urology, Vol.20, No.5, pp. 6897-6906, 2013
    Abstract Introduction: Prostate biopsies are usually taken from the peripheral rather than anterior region of the prostate. Consequently, tumors originating from the anterior apical region and transition zones may be under-sampled. We examined whether addition of transrectal anterior biopsy (TAB) would improve efficacy of prostate biopsies.
    Materials and methods: Simulations of TAB and sextant biopsy (SB) were performed using computer models of 86 autopsy prostates (AP) and 40 radical prostatectomy (RP) specimens. TAB was obtained bilaterally from apex, mid, and base regions by advancing the biopsy needle 5 mm-35 mm beyond the prostatic capsule. A phase I clinical… More >

    Jessica N. Lange1, Linda Easter1, Robert Amoroso1, Debra Benfield1, Patrick W. Mufarrij2, John Knight3, Ross P. Holmes3, Dean G. Assimos3
    Canadian Journal of Urology, Vol.20, No.5, pp. 6922-6926, 2013
    Abstract Introduction: Certain dietary modifications limit the risk of stone recurrence. Compliance is an important component of dietary therapy for stone prevention, and self-efficacy is an important ingredient of compliance. We developed an internet program to facilitate dietary compliance for stone prevention and performed a pilot study to assess its effectiveness.
    Materials and methods: The internet program provides information regarding dietary modifications including increased fluid consumption, limited animal protein, sodium, and oxalate intake, and adequate calcium consumption. Participants record their daily food and fluid intake and receive immediate feedback as to whether they were compliant or not. Five… More >

    Robot assisted radical prostatectomy: how I do it. Part I: patient preparation and positioning

    Roger F. Valdivieso, Pierre-Alain Hueber, Kevin C. Zorn
    Canadian Journal of Urology, Vol.20, No.5, pp. 6957-6961, 2013
    Abstract Radical prostatectomy remains the standard treatment for long term cure of clinically localized prostate cancer, offering excellent oncologic outcomes, with cancer-specific survival approaching 95% at 15 years after surgery. The introduction of the “da Vinci Robotic Surgical System” (Intuitive Surgical, Sunnyvale, CA, USA) has been another important step toward a minimally invasive approach to radical prostatectomy. Technologic peculiarities, such as three-dimensional vision, wristed instrumentation with seven degrees of freedom of motion, lack of tremor, a 10x-magnifcation and a comfortable seated position for the surgeon has added value to the surgeon and patient.

    A magnetic mass within the bladder

    Fahad Alyami, Jeffrey Himmelman, Thomas Whelan
    Canadian Journal of Urology, Vol.20, No.5, pp. 6962-6963, 2013
    Abstract A search of the literature finds that there have been many case reports documenting a wide array of objects found within the bladder, ranging from magnets and paper clips to telephone and aluminum wire. The goal of treatment is to remove the object quickly, using the least invasive method possible. Therefore, the ideal treatment is removal through endoscopic means; however, in some cases, the size, mobility and shape of the foreign body can prevent its removal endoscopically and more invasive means must be employed. We present a case of a patient who inserted 150 magnetic More >

    Acute bilateral ureteral obstruction secondary to guaifenesin toxicity

    Patrick A. Cockerill, Mitra R. de Cógáin, Amy E. Krambeck
    Canadian Journal of Urology, Vol.20, No.5, pp. 6971-6973, 2013
    Abstract Several medications or their metabolites have been associated with urolithiasis, although overall they remain an infrequent cause of urolithiasis. Guaifenesin stones were originally reported as complexed with ephedrine, and subsequent reports have demonstrated pure guaifenesin stones, occurring after long term abuse. We report a case of a 23-year-old male who ingested a large, one time dose of guaifenesin, resulting in acute bilateral ureteral obstruction, which, to our knowledge, is the frst such reported case in the literature.

    Congenital urethral polyps in the pediatric population

    Xiaolong S. Liu1, Portia A. Kreiger2, Sharon W. Gould3, Jennifer A. Hagerty1
    Canadian Journal of Urology, Vol.20, No.5, pp. 6974-6977, 2013
    Abstract Congenital urethral polyps are a rare entity. Most commonly, they present as benign posterior urethral growths in the pediatric male patient. However, reports of urethral polyps in female patients or even those with an anterior urethral location can also be found in the literature. Patients can present with a spectrum of symptoms including dysuria, hematuria, and obstructive type urinary complaints. Diagnosis in these cases includes a combination of medical imaging (e.g. ultrasound, fluoroscopic, CT or MRI), direct endoscopic visualization, and final surgical pathology. Treatment involves surgical removal either via an endoscopic or open approach. More >
