    Felix K-H. Chun1, Nazareno Suardi1, Paul Perrotte2, Thierry Lebeau2, Jean-Pierre Guay2, Serge Benayoun2, Alvaro Ramirez2, François Bénard2, Michael McCormack2, Luc Valiquette2, Pierre Karakiewicz1,2
    Canadian Journal of Urology, Vol.14, No.6, pp. 3727-3733, 2007
    Abstract Introduction: Controversy persists about whether men should be screened for prostate cancer. On the other hand, the benefit of colorectal cancer screening has been proven for men starting at age 50. We aimed to examine the rate of exposure to previous screening tests for prostate cancer and colorectal cancer in a cohort of men living in Quebec.
    Materials and methods: As part of an event promoting early prostate cancer detection, 347 men aged 50 to 69 without an established diagnosis of prostate cancer agreed to reply to questions in a previously validated questionnaire. The self-administered questionnaire, which… More >

    Anew suture technique for anastomosis in radical retropubic prostatectomy and early removal of urethral catheter

    Levent N. Türkeri, Yusuf Temiz, Cenk M. Yazici, Ilker Tinay
    Canadian Journal of Urology, Vol.14, No.6, pp. 3734-3738, 2007
    Abstract Introduction: A modified suture technique for urethro-vesical anastomosis during radical retropubic prostatectomy was developed and utilized in a cohort of patients. Comparative analysis of postoperative outcome was performed with a previous group of patients who had an anastomosis with the conventional technique.
    Material and methods: A consecutive group of patients who underwent radical retropubic prostatectomy in our department with the diagnosis of localized prostate cancer was included in this retrospective study. Urethro-vesical anastomosis was performed either with the new or conventional method (CM). Outcome data of these two different patient sets were compared.
    Results: One-hundred and one… More >

    Pediatric renal cell carcinoma as second malignancy: reports of two cases and a review of the literature

    Kristian T. Schafernak1, Ximing J. Yang1,2, Wei Hsueh3, Jan L. Leestma3, Jennifer Stagl4, Stewart Goldman4
    Canadian Journal of Urology, Vol.14, No.6, pp. 3739-3744, 2007
    Abstract Pediatric renal cell carcinoma (RCC) is relatively rare and appears to comprise a group of tumors distinct from RCCs typically seen in adults. Recently described tumors show an association with neuroblastoma or specific chromosomal translocations. Only rarely have other childhood cancers been associated with pediatric RCC. We present two cases of pediatric RCC following treatment of other childhood malignancies not previously described, supratentorial primitive neuroectodermal tumor and acute lymphoblastic leukemia, and review the literature on pediatric RCC. As the RCCs were discovered as incidental radiologic findings, we emphasize the importance of close follow-up (including imaging) More >

    Bladder contracture: review for intravesical bacillus Calmette-Guerin complication

    A. Hameed, N. Sezian, A. Thwaini
    Canadian Journal of Urology, Vol.14, No.6, pp. 3745-3749, 2007
    Abstract Introduction: We are reporting a case of bladder contracture post intravesical bacillus Calmette-Guerin (BCG) therapy; to our knowledge only two cases were reported. We present the clinical history/presentation, investigation and the outcome of the treatment. Approximately 75%-85% of patients with bladder cancer present with disease confined to the mucosa (stage Ta-CIS) or submucosa (stage T1). The management of non-muscle invasive bladder cancer has become more complex with regard to initial investigation, treatment and follow-up. In high-grade tumors, BCG therapy has proven to be superior to intravesical chemotherapy. BCG therapy prevents, or at least delays, tumor progression.… More >

    Unusual presentation of seminal vesiculitis in an infertile man

    Fernando Tadeu Andrade-Rocha
    Canadian Journal of Urology, Vol.14, No.6, pp. 3750-3752, 2007
    Abstract Seminal vesiculitis is generally not investigated in infertile men, since it is uncommon and often nonspecific in signs and symptoms. In this article, the author reports an unusual presentation of seminal vesiculitis, incidentally diagnosed in a man referred for semen analysis to investigate infertility. Analyses of physical properties of the ejaculate (coagulation, liquefaction, volume, viscosity and pH) and of biochemical markers of the prostate (total calcium and zinc) and seminal vesicle (fructose and inorganic phosphorus) detected a dysfunction of the seminal vesicles that was subsequently diagnosed as vesiculitis using transrectal ultrasound. After treatment with a More >

    MINIMALLY INVASIVE AND ROBOTIC SURGERY

    Robot-assisted radical cystectomy versus open radical cystectomy: assessment of postoperative pain

    Khurshid A. Guru1,4, Gregory E. Wilding3,6, Pamela Piacente1, Jannah Thompson4, Wei Deng6, Hyung L. Kim1,4, James Mohler1,4, Kathleen O’Leary2,5
    Canadian Journal of Urology, Vol.14, No.6, pp. 3753-3756, 2007
    Abstract Introduction: To date, no study has compared postoperative pain and requirement for pain medications in open versus robot-assisted radical cystectomy. Patient reported pain and opiate use were reviewed retrospectively using prospectively collected data from postoperative day one to day of discharge.
    Materials and methods: Twenty consecutive robot-assisted radical cystectomy patients were compared to the prior 20 patients who underwent open radical cystectomy. Data was collected prospectively to determine opiate requirements and pain scores in each group. Daily opiate use was converted to morphine sulfate equivalents (MSE) to facilitate comparison. A Likert pain perception scale was used to… More >

    CASE REPORT

    Pheochromocytoma of the urinary bladder

    Ahmed S. Safwat, Nabil K. Bissada
    Canadian Journal of Urology, Vol.14, No.6, pp. 3757-3760, 2007
    Abstract Objective: Pheochromocytoma of the urinary bladder is rare. Herein, we report our experience with pheochromocytoma of the urinary bladder in three patients.
    Materials and methods: Records of three consecutive patients diagnosed with bladder pheochromocytoma were reviewed. Patients' age, sex, presentation, associated conditions, diagnostic and imaging modalities utilized, management and follow up were recorded.
    Results: The three patients included one child and two adults. An 11-year-old female presented with hematuria and bladder mass. Transurethral biopsy was non-diagnostic and she underwent partial cystectomy with eventual diagnosis of pheochromocytoma. Of the two adults, one was a 35-year-old female with history… More >

    CASE REPORT

    Obstructive uropathy secondary to inguinal bladder hernia: case report and review of the literature

    Endre Z. Neulander, Jacob Kaneti, Josef Klain, Solomon Mizrahi
    Canadian Journal of Urology, Vol.14, No.6, pp. 3761-3763, 2007
    Abstract We report a case of a large inguino-scrotal bladder hernia presenting with obstructive lower urinary symptoms and causing massive unilateral uretero-hydronephrosis with ipsilateral renal function deterioration. Careful anamnesis and computer tomography (CT) scan of the abdomen and pelvis were important for the diagnosis. Open surgery with mesh hernia repair was successful. The obstructive lower tract symptoms subsided following surgery while the deteriorated renal unit regained only part of its function. More >

    CASE REPORT

    Primary signet-ring cell carcinoma of the prostate

    Yoh Matsuoka1,3, Gaku Arai1, Hisashi Ishimaru1, Kentaro Takagi1, Yuji Ito2
    Canadian Journal of Urology, Vol.14, No.6, pp. 3764-3766, 2007
    Abstract We report a rare case of primary signet-ring cell carcinoma of the prostate in an advanced stage. A 62-year-old man with serum level of prostate-specific antigen at 364.70 ng/ml was diagnosed as having cT4N1M1c prostatic signet-ring cell carcinoma of Gleason score 5 + 4 = 9. Immunohistochemical examination demonstrated cytoplasmic immunoreactivity to prostate-specific antigen in signet-ring cancer cells. The intracytoplasmic vacuoles in the signet-ring cells showed mucin production with a positive staining with periodic acid-Schiff. Although the patient received hormonal therapy, the disease progressed and lead to death 15 months after the diagnosis. The clinical More >

    Mixed gonadal dysgenesis and Denys-Drash syndrome: urologists should screen for nephrotic syndrome

    Oleg Shapiro1, Thomas R. Welch2, Maryellen Sheridan1, Susan Stred2, Jyoti Upadhyay1
    Canadian Journal of Urology, Vol.14, No.6, pp. 3767-3769, 2007
    Abstract Objective: We present a child with Denys-Drash syndrome recognized after surgery for mixed gonadal dysgenesis, and discuss screening procedures the urologist should consider in similar circumstances.
    Case report: A 1-year-old child with XY gonadal dysgenesis underwent genital reconstruction. The postoperative period was complicated by incisional drainage, which led to the recognition of a nephrotic syndrome. Molecular analysis of the WT-1 gene confirmed a mutation associated with the Denys-Drash syndrome.
    Conclusion: The Denys-Drash syndrome should be suspected in children with XY gonadal dysgenesis. The presence of urine protein should be sought in such children, and if present, consultation More >

    Embolization with Tornado coils to control bleeding from an arterioureteral fistula

    Bruce L. Jacobs, Jodi K. Maranchie
    Canadian Journal of Urology, Vol.14, No.6, pp. 3770-3772, 2007
    Abstract Arterioureteral fistulae are rare, but potentially life-threatening causes of bleeding. We present a case of an 82 year-old woman with refractory, transfusion-dependent bleeding from an arterial fistula to her right ureteral stump, following right radical nephrectomy for advanced renal cell carcinoma. Cystoscopy with retrograde ureteral stump embolization using Tornado (Cook Medical, Bloomington, Indiana, USA) coils plus a slurry of thrombin-soaked Gelfoam (Pfizer Inc., New York, New York, USA) was performed, which led to prompt resolution of the patient’s hematuria requiring no further hospitalizations or transfusions. Retrograde insertion of coils and injection of thrombin-soaked Gelfoam can More >

    Laparoscopic pyeloplasty for ureteropelvic junction obstruction in a horseshoe kidney

    Can Talug, Adam E. Perlmutter, Tarun Kumar, Stanley Zaslau, William F. Tarry
    Canadian Journal of Urology, Vol.14, No.6, pp. 3773-3775, 2007
    Abstract With a continued movement toward minimally invasive surgical interventions, the range of applications treated with laparoscopic surgery will continue to grow. Laparoscopy is a preferred method for various reasons, including decreased postoperative pain, shorter inpatient hospital stays, and decreased convalescence. Ureteropelvic junction obstruction (UPJO) has traditionally been treated by open pyeloplasty. In patients with horseshoe kidneys, the blood supply is aberrant, which adds complexity to the procedure. We present the second reported case of a pediatric patient with a horseshoe kidney found to have UPJO who was successfully treated with transperitoneal laparoscopic pyeloplasty. More >
