    The role of the bladder surface in interstitial cystitis/painful bladder syndrome

    Joel M. H. Teichman1, Robert Moldwin2
    Canadian Journal of Urology, Vol.14, No.4, pp. 3599-3607, 2007
    Abstract Introduction: Interstitial cystitis (IC) is a potentially severe and debilitating condition of the bladder. Numerous factors have been implicated in its pathogenesis.
    Materials and methods: A literature review was conducted on the following topics: urothelium, mucosal lining, interstitial cystitis, bladder, and glycosaminoglycans.
    Results: A commonly proposed cause for IC is a defect or alteration in the bladder surface leading to increased permeability to noxious urinary solutes and ultimately to tissue inflammation and neurogenic upregulation. Support for this concept is drawn from studies of the structure, function, and composition of the bladder surface. The cause(s) of this alteration More >

    Toxicity and health-related quality-of-life assessment in prostate radiotherapy

    George Rodrigues1,2, Michael Lock1, David D’Souza1
    Canadian Journal of Urology, Vol.14, No.4, pp. 3608-3615, 2007
    Abstract The use of radiation therapy in the radical treatment of prostate cancer can lead to potential acute and long-term toxicity and health-related quality-of-life (HRQoL) changes. Ongoing investigation into dose-escalation, dose-per-fraction escalation, new radiation treatment technology/ paradigms, and novel systemic therapy may have either positive and/or negative effects on normal tissue toxicity/ HRQoL. Herein, common toxicity scales and HRQoL instruments that attempt to describe the deleterious effects of prostate radiation therapy are reviewed. More >

    Correlation of pathology with tumor size of renal masses


    Canadian Journal of Urology, Vol.14, No.4, pp. 3616-3620, 2007
    Abstract Objective: The current standard of care for radiographically identified enhancing renal lesions is surgical removal. However, some of these lesions prove to be benign and did not truly warrant extirpation. Mass size has been traditionally described as a parameter to predict the malignant potential. We compiled our experience with surgically treated renal masses and correlated lesion size with final pathology.
    Materials and methods: We performed a retrospective analysis of extirpative renal surgery and resultant renal mass pathology from 1998-January 2006. Nephrectomies performed for non-malignant disease or transitional cell carcinomas were excluded. Renal tumors were staged by the… More >

    Eric Berthelet1, Tom Pickles2, Pauline T. Truong1, Mitchell Liu3, Howard H. Pai1, Winkle B. Kwan3, Jan T.W. Lim1
    Canadian Journal of Urology, Vol.14, No.4, pp. 3621-3627, 2007
    Abstract Purpose: To evaluate the optimal duration of androgen deprivation therapy (ADT) in patients with prostate cancer treated with external beam radiotherapy (EBRT), who present with PSA levels >20 ng/mL.
    Materials and methods: A total of 307 patients presenting with a PSA >20 ng/ml were treated with EBRT and ADT. The cohort was divided into four groups according to the duration of ADT: Group 1 received <6 months (n=71), group 2 received 6-12 months (n=80), group 3 received 12-24 months (n=72), and group 4 received >24 months (n=84) of ADT. The endpoints analyzed were biochemical control (bNED), overall… More >

    Frederick P. Mendiola, Kevin C. Zorn, Ofer N. Gofrit, Albert A. Mikhail, Marcelo A. Orvieto, Lambda P. Msezane, Gary D. Steinberg
    Canadian Journal of Urology, Vol.14, No.4, pp. 3628-3634, 2007
    Abstract Introduction: Radical cystectomy (RC) with urinary diversion remains as one of the more complex urological procedures despite considerable progress in surgical technique. Increasing patient age, along with associated age-related comorbidities, may portend a poor outcome in those undergoing such complicated surgical procedures. Herein, we report our experience with radical cystectomy in the elderly population.
    Methods: We retrospectively reviewed our RC results from 1995 to 2003. Patients ≥80 years old were included in this analysis. Perioperative outcomes, as well as overall and disease-free survival were evaluated.
    Results: A total of 517 patients underwent RC with urinary diversion during… More >

    MINIMALLY INVASIVE AND ROBOTIC SURGERY

    Impact of previous inguinal hernia repair on transperitoneal robotic prostatectomy

    Rajesh G. Laungani, Sanjeev Kaul, Fred Muhletaler, Ketan K. Badani, James Peabody, Mani Menon
    Canadian Journal of Urology, Vol.14, No.4, pp. 3635-3639, 2007
    Abstract Objective: Several investigators have noted that previous inguinal hernia repair with or without the use of prosthetic mesh might be a relative contraindication for open or laparoscopic radical prostatectomy due to the presence of adhesions and the difficulty of tissue dissection. We aimed to evaluate the impact of previous hernia repair on the performance and feasibility of robotic prostatectomy.
    Materials and methods: We performed a retrospective analysis of 354 patients who underwent robotic prostatectomy at our institution. The three patient groups were: 292 patients who had no prior hernia repair (group 1), 50 patients who had prior… More >

    MINIMALLY INVASIVE AND ROBOTIC SURGERY

    Robot-assisted partial cystectomy for the treatment of urachal carcinoma

    Danny M. Rabah
    Canadian Journal of Urology, Vol.14, No.4, pp. 3640-3642, 2007
    Abstract The traditional treatment of choice for urachal carcinoma has been either an open radical cystectomy or the more recently accepted extended partial cystectomy and umbilectomy. Recently a laparoscopic technique has been reported. We report for the first time a robot-assisted technique for an extended partial cystectomy with en bloc umbilectomy for the management of urachal carcinoma in a 49-year-old man. More >

    CASE REPORT

    Prostatic abscess as a delayed complication following cryosurgery for primary prostate cancer

    Stephanie H. Chen, Vladimir Mouraviev, Janice M. Mayes, Thomas J. Polascik
    Canadian Journal of Urology, Vol.14, No.4, pp. 3646-3648, 2007
    Abstract Prostatic abscess is a rare and potentially life-threatening disease when left untreated. We report the first case of a man who developed a prostatic abscess as a long-term complication of cryoablation for primary prostate cancer. Timely diagnosis with non-contrast computed tomography (CT) scan, retrograde CT cystogram to ensure no bladder involvement, percutaneous drainage under CT-guidance, and antibiotic treatment sensitive to the causative organism were crucial for prompt recovery.

    Canadian Journal of Urology, Vol.14, No.4, pp. 3649-3650, 2007
    Abstract Renal infiltration of colon adenocarcinoma is a rare event. The authors present the case report of a 52-year-old female who had a high carcinoembryonic antigen level 18 months after right hemicolectomy and a chemotherapy regimen to treat transverse colon adenocarcinoma. The patient presented with cancer reccurrence after 12 months, and underwent a paraaortic lymphadenoctomy and a second adjuvant chemotherapy with the folfox regimen. Abdomen computerized tomography revealed two solid masses in the right kidney, without evidence of any other metastatic sites. A nephrectomy was performed in the right kidney followed by adjuvant chemotherapy. More >

    Ruptured superficial dorsal vein of the penis masquerading as a penile fracture: case report

    Adam E. Perlmutter1, Lawrence Roberts2, Hesam Farivar-Mohseni1, Stanley Zaslau1
    Canadian Journal of Urology, Vol.14, No.4, pp. 3651-3652, 2007
    Abstract Acute onset of pain, swelling, and ecchymosis of the penis during sexual intercourse indicate a penile fracture until proven otherwise. However, there have been few case reports of isolated injuries to the dorsal penile artery or dorsal vein mimicking a penile fracture. Presented herein is a rare case of a patient who ruptured his superficial dorsal vein during intercourse. More >

    Extended-spectrum beta-lactamase gram-negative sepsis following prostate biopsy: implications for use of fluoroquinolone prophylaxis

    Glenn M. Cannon, Jr.1, Marc C. Smaldone1, David L. Paterson2
    Canadian Journal of Urology, Vol.14, No.4, pp. 3653-3655, 2007
    Abstract Extended-spectrum beta-lactamase (ESBL) producing organisms are resistant to penicillins, cephalosporins, aminoglycosides, trimethoprim-sulfamethoxazole, aztreonam, and most fluoroquinolones. We report a case of a 72-year-old man who developed septic shock with an ESBL organism after a transrectal ultrasound (TRUS)-guided prostate biopsy despite having received fluoroquinolone prophylaxis. The patient recovered with intravenous ertapenem. Fluoroquinolone-resistant bacteria are increasing in prevalence. This needs to be recognized when the antibiotic choice for pre-procedure prophylaxis is made. More >

    Naser M. Al-Awadhi1, Nabeel Al-Brahim1, Mahmoud S. Ahmad1, Encho Yordanov2
    Canadian Journal of Urology, Vol.14, No.4, pp. 3656-3659, 2007
    Abstract Background: A condom catheter is a commonly used drainage system for incontinent patients. However, it is associated with different complications including infection and erosion. One very rare complication that has been recognized is the development of giant fibroepithelial polyps in the penis; to date, to the best of our knowledge, seven cases have been reported in the literature. We report a new case of giant fibroepithelial polyp associated with long-term condom catheter use.
    Case summary: A 43-year-old incontinent man who had been using a condom catheter for 14 years following a motor vehicle accident presented with a… More >
