Abstract A patient presented with a metal ring around the base of his penis. The ring had been placed 3 years prior to presentation. Intra-operative findings revealed a ventral erosion with complete transection of the urethra and massive fixed lymphedema of the penile skin distal to the ring. Treatment consisted of removal of the ring with metal shears and bolt cutters. Small reduction of the edema was seen 3 months following removal, and the patient refused further treatment. The most interesting part of the outcome was the preservation of penile urethral voiding although intromission was not More >

Abstract Objective: To review our experience in managing the uncommon problem of a retained Foley catheter secondary to an inability to deflate the catheter balloon.
Methods: A chart review of 13 patients in whom it was not possible to deflate their Foley catheter balloons was performed. We review the various techniques used to deflate their catheter balloons and present a modified algorithm.
Results: In 23% of our patients, passive aspiration with a syringe successfully deflated the balloon. In 31% of our patients, cutting the catheter with or without subsequent aspiration successfully deflated the balloon. In 15% of our patients, More >

Abstract Objectives: To correlate the primary Gleason pattern among patients with biopsy-derived Gleason 7 tumors with the radical prostatectomy specimen Gleason grading and other clinical and pathologic outcomes.
Methods and materials: Among 474 patients who underwent radical prostatectomy for clinically localized prostate cancer between 1997-2001, 205 (43%) had Gleason 7/10 tumors on pre-operative needle biopsy. Among these patients, 148 (72.2%) were assigned a primary Gleason 3 pattern (3+4=7) and 57 (27.8%) were assigned a primary Gleason 4 pattern (4+3=7). The two groups were compared with respect to age, serum PSA levels, Gleason grade in the radical prostatectomy specimen,… More >

Abstract Background: Wilms' Tumor is the most common malignant neoplasm of the urinary tract in children. Since 1969, the National Wilms' Tumor Study Group (NWTSG) has contributed to improving the clinical management and outcome of children affected by Wilms' Tumor. We have managed our patients according to NWTSG protocols and report our results herein.
Methods: Retrospective chart review of consecutive patients presenting at the Children's Hospital of Eastern Ontario (CHEO) with a diagnosis of Wilms' Tumor between April 1990 and March 2001.
Results: Forty patients with Wilms' Tumor (18 M/22 F) were diagnosed at CHEO during this interval. Mean… More >

Abstract Double-J ureteral stents facilitating the drainage of urine from the kidney to the bladder are widely used. Stents designed for patient self-removal are commonplace. We report a case of urosepsis that lead to the incidental discovery of a failed self-removal of a double-J ureteral stent. The retrieval cord broke during self-removal and the patient mistook the string for the stent. Adequate patient education is essential to assure successful self-removal. More >

Abstract Hypercalcemia associated with transitional cell carcinoma (TCC) is rarely encountered. We report a case of TCC of bladder with documented production of parathyroid hormone related protein (PTHrP). Our patient had a rapidly progressive course and died 2 months after radical cystectomy. Literature suggests that these patients present with advanced stage and carry a poor prognosis. The histopathologic features, treatment and prognosis associated with this rare paraneoplastic syndrome are reviewed. More >

Abstract Purpose: Prostate cancer represents a large part of the workload for radiation oncology departments in Canada. Recent evidence suggests that conformal external beam radiotherapy improves results. The planning and treatment process for conformal patients requires a greater amount of resources that are in short supply in Ontario. An understanding of these differences is important to provide an accurate estimate of future radiation needs of the province. These differences can be quantified in a cost model that portrays the direct costs of delivering external beam radiotherapy in Ontario. With a developed cost model, a prospective direct cost… More >

Abstract Objective: To examine the change of histologic grade of untreated, low to intermediate grade, clinically localized prostate cancer over time on repeat prostate biopsy.
Methods and materials: In a prospective single-arm cohort study, patients were managed with observation alone unless they met pre-defined criteria of disease progression (PSA, clinical or histologic progression). Sixty-seven (54%) of a total of 123 eligible patients underwent follow-up prostate biopsy. Median time to the follow-up biopsy was 22 months (range: 7-60).
Results: On the follow-up biopsy, Gleason score was unchanged in 20 patients (30%), upgraded in 19 (28%), and downgraded in 27 (40%).… More >

Abstract Bladder agenesis is an extremely rare congenital anomaly. We report a case of bladder agenesis in a newborn girl with a prolapsing ectopic ureter and solitary dysplastic kidney. The classification of this disorder and the management of this patient are reviewed. More >

Abstract Purpose: To compare the incidence of infection between a 1 day and a 3 day antibiotic prophylaxis regimen for transrectal ultrasound (TRUS) guided prostate biopsy in a prospective, randomized open-label trial.
Materials and methods: TRUS examination was performed in the left lateral decubitus position using a Brüel and Kjaer 7 MHz rectal probe. Biopsies were carried out with an 18 gauge Tru-cut needle fired by the hand-held Biopsy gun. An average of eight core biopsies (range 6 to 12) was taken. From May 15, 2000 to May 16, 2001, 363 patients were enrolled in this study. Patients… More >
