    Endoscopic management of upper tract urothelial carcinoma

    Anthony J. Polcari, Cory M. Hugen, Thomas M. Turk
    Canadian Journal of Urology, Vol.16, No.6, pp. 4887-4894, 2009
    Abstract While radical nephroureterectomy remains the gold standard of treatment for patients with upper tract urothelial tumors, technological advances have made endoscopic management possible. The careful selection of patients for such an approach is dependent upon an accurate diagnosis and an understanding of the natural history of the disease. High grade tumors behave aggressively and warrant radical extirpation unless an absolute contraindication exists. Motivated patients with low grade tumors and relative contraindications to nephroureterectomy can be managed with percutaneous or retrograde ureteroscopic techniques. High recurrence rates in the ipsilateral upper tract and bladder mandate close surveillance More >

    Is lymphadenectomy indicated in patients with T1 moderately differentiated penile cancer?

    Sameer M. Malhotra, Robert V. Rouse, Raymond Azzi, Jeffrey Reese
    Canadian Journal of Urology, Vol.16, No.6, pp. 4895-4900, 2009
    Abstract Objective: In patients with penile squamous cell carcinomas (SCCs), lymphadenectomy can be curative and should be considered in cases deemed high risk for metastatic spread to regional lymph nodes. Management of patients without palpable lymphadenopathy remains controversial. Current guidelines for T1 penile SCCs based on previous studies have suggested that moderately differentiated tumors are at low risk for metastatic disease; however given our experience with such patients we sought to examine whether such tumors were truly observable or should be treated more aggressively.
    Materials and methods: A retrospective chart review of penile cancer cases at three institutions… More >

    Effect of cranberry drink on bacterial adhesion in vitro and vaginal microbiota in healthy females

    Jana Jass1, Gregor Reid2
    Canadian Journal of Urology, Vol.16, No.6, pp. 4901-4907, 2009
    Abstract Introduction/objective: Cranberries have been shown to produce urinary metabolites that influence uropathogen adhesion and prevent urinary tract infections. This study was designed to determine if consuming reconstituted, unsweetened cranberry drink from extract retained its bioactive properties by reducing uropathogen adhesion without adversely affecting urinary calcium, magnesium and the vaginal microflora.
    Materials and methods: A randomized crossover study was undertaken in 12 healthy women consuming reconstituted unsweetened cranberry drink, CranActin or water. The urine was collected at 4 hours and 1 week of consumption and evaluated for antiadhesive properties and urinary pH, calcium and magnesium. Vaginal swabs were… More >

    Yiu-Keung Lau1,2, C. Ellen Lee3, Heather J. Prior4, Lisa M. Lix5, Colleen J. Metge6, William D. Leslie7
    Canadian Journal of Urology, Vol.16, No.6, pp. 4908-4914, 2009
    Abstract Introduction: Prostate cancer is the most common noncutaneous malignancy diagnosed in men. The use of androgen deprivation therapy (ADT) is the mainstay of treatment for metastatic disease. The use of ADT has been reported to increase the risk of osteoporosis in men with prostate cancer, with higher risk of fracture than age matched controls. We sought to confirm the higher fracture risk of men with prostate cancer on ADT in the Canadian population.
    Methods: We used the Population Health Research Data Repository housed at Manitoba Centre for Health Policy to identify all cases of fractures of the… More >

    Renal tumors and the risk of malignancy based on size

    Behrooz Azizi1,2, Thomas Whelan2,3, Michael Morse2,3
    Canadian Journal of Urology, Vol.16, No.6, pp. 4921-4923, 2009
    Abstract Purpose: To determine the incidence of malignancy in resected renal tumors in a subpopulation of Canadian patients and the significance of tumor size, patient's demographics, and whether the tumor was an incidental finding.
    Methods: Medical records of 168 consecutive nephrectomies performed between March 2003 and June 2008 at our institution were reviewed retrospectively.
    Results: Average age of the patients was 61 years old (SD 11, range 28-89) and male to female ratio was 1.3:1. Total of 180 masses were resected in 168 nephrectomies (128 radical, 40 partial) during the study period. Of the 180 masses, 20 (11%) were… More >

    Ungated extracorporeal shock wave lithotripsy: safe and effective in the pediatric population

    Jeffrey S. Palmer
    Canadian Journal of Urology, Vol.16, No.6, pp. 4924-4926, 2009
    Abstract Purpose: Ungated extracorporeal shock wave lithotripsy (SWL) is unsynchronized to the patient's electrocardiogram. Although ungated extracorporeal shock wave lithotripsy (SWL) is associated with cardiac arrhythmias in adults, the incidence of arrhythmias in children has not been established. We report on the safety and efficacy of ungated SWL of renal calculi in children.
    Materials and methods: We evaluated all children less than 18 years of age undergoing ungated SWL for renal calculi. Lithotripsy with gradual incremental energy increase was used to treat the stones. Patients were monitored for arrhythmias and other standard monitoring intraoperatively and postoperatively.
    Results: Twenty-four consecutive… More >

    Intravesical therapy use in the high risk patient: practice patterns in an equal access healthcare institution before and after national guidelines

    Jennifer M. Pugliese, Richard N. Greene, Andrew C. Peterson
    Canadian Journal of Urology, Vol.16, No.6, pp. 4927-4931, 2009
    Abstract Purpose: We examined patterns of intravesical therapy use in nonmuscle invasive bladder cancer over the last 10 years at our institution where there is equal access to healthcare. We further examined any affect that the introduction of national guidelines may have had on the utilization of intravesical therapy in these patients.
    Materials and methods: An Institutional Review Board (IRB) approved retrospective chart review was performed between the years 1997 and 2007. Only those with premalignant or malignant pathology, as identified using intradepartmental surgical logs and pathology reports, were included.
    Results: Four hundred seventeen procedures, representing 228 patients, were… More >

    MINIMALLY INVASIVE AND ROBOTIC SURGERY

    Partial ureteropelvic junction obstruction managed by robotic excision and ureteropyelostomy

    Kyle A. Richards, Iqbal Singh, Ashok K. Hemal
    Canadian Journal of Urology, Vol.16, No.6, pp. 4932-4935, 2009
    Abstract Ureteropelvic junction obstruction is a fairly common diagnosis in urology. With the emergence of robotic surgery in urology, complex ureteral reconstruction of the proximal, mid, and distal ureter is being undertaken with robotic assistance with excellent results. We present the case of a 61-year-old male who presented with an atypical partial ureteropelvic junction obstruction. The etiology was suspected to be from external compression of the proximal ureter by a calcifi ed periureteral mass. The mass was theorized to be secondary to occult ureteral perforation and extraluminal migration of a renal calculus during repeat percutaneous nephrolithotomy More >

    Laparoscopic management of extensive ureteral fi broepithelial polyps

    David S. Bargnesi1, Ronney Abaza2, Steven H. Selman1
    Canadian Journal of Urology, Vol.16, No.6, pp. 4936-4938, 2009
    Abstract Fibroepthelial polyps are uniformly benign tumors of the collecting system which may cause obstruction of an affected renal unit. We present a unique case of a 34-yearold male with a solitary functioning kidney who presented with fl ank pain and renal insuffi ciency. Radiographic and ureteroscopic evaluation revealed ureteral obstruction due to extensive polyps. After ureteral stenting and normalization of renal function, successful polyp excisions were performed laparoscopically through a ureterotomy. The pathology revealed benign fi broepithelial polyps. The patient remained asymptomatic until 3 years later when ureteroscopy performed for a calculus revealed a widely More >

    CASE REPORT

    Fistulization in a locally advanced case of squamous cell carcinoma of the prostate

    O. A. Raheem1, R. G. Casey1, C. Attah1, L. Clarke2, A. McGrath3, E. Gaffney2, D. Hollywood4, T. E. D. McDermott1, T. H. Lynch1
    Canadian Journal of Urology, Vol.16, No.6, pp. 4941-4945, 2009
    Abstract Squamous cell carcinoma of the prostate gland is very rare, constituting 0.5%-1% of all prostatic malignancies. Though it has a similar clinical presentation to prostate cancer, the tumor is more aggressive, spreading to bone, liver and lung. The median survival time is approximately 14 months. Diagnosis is exclusively by histology. Therapeutic options may include radical surgery, radiotherapy, chemotherapy, hormonal therapy or a combination of these treatments. We present a case of locally advanced squamous cell carcinoma of the prostate and comment on its management and subsequent disease related complication. More >

    Testicular infarction as a sequela of inguinal hernia repair

    Lei Chu, Timothy D. Averch, Stephen V. Jackman
    Canadian Journal of Urology, Vol.16, No.6, pp. 4953-4954, 2009
    Abstract Background: Testicular atrophy and necrosis as a result of ischemic orchitis is a well-established complication after inguinal hernia repair. We reviewed four patients with a recent history of inguinal hernia repair and subsequently developed ischemic orchitis to evaluate management options to provide symptomatic relief and prevent testicular atrophy.
    Case series: The first patient underwent loosening of inguinal hernia mesh for scrotal pain and decreased arterial testicular flow 8 hours after inguinal hernia repair. The second patient developed ischemic orchitis 20 hours after inguinal herniorrphaphy and required removal of mesh. Neither patient had testicular atrophy at their follow More >

    Blunt testicular trauma results in rupture of mixed germ cell tumor

    Adam Luchey, Aimee Rogers, Susan E. Saunders, H. James Williams, Henry J. Fooks, Stanley Zaslau
    Canadian Journal of Urology, Vol.16, No.6, pp. 4955-4957, 2009
    Abstract It is extremely rare that a documented case of blunt trauma results in rupture of a testicular tumor. We present the case of a 24-year-old man who was crushed by a tree who developed spontaneous testicular rupture. At surgical exploration, he was found to ultimately have a mixed germ cell tumor of the testicle. This case illustrates the importance of physical examination, patient clinical history, and scrotal ultrasound in the management of scrotal trauma. In this instance, the testicular mass ruptured and lead to signifi cant testicular hemorrhage. More >
