Abstract Objective: Horseshoe kidney is one of the most common congenital anomalies of renal structure. Not infrequently, surgical management of both benign and malignant disorders is required in patients with horseshoe kidney due to the susceptibility to certain conditions. The literature suggests a greater proclivity to certain renal tumors with this anomaly. We present three cases of malignancy in horseshoe kidneys. The unique technical challenges presented by these cases and the surgical approaches are discussed.
Methods: Three patients with tumors involving horseshoe kidneys are reviewed and their management discussed.
Results: Two patients were found to have renal cell carcinoma… More >

Abstract Background: In Canada, waiting times for cancer care have been increasing, particularly for patients with genitourinary malignancies. We examined whether delay from diagnosis for patients undergoing surgery for clinically localized prostate cancer affects cancer cure rates.
Methods: We conducted a historical cohort study among 645 patients who underwent radical prostatectomy between 1987 and 1997, using biochemical recurrence (PSA elevation) and metastasis as endpoints. We examined whether patients who underwent surgery ≥3 months (delayed surgery group) from the date of diagnosis had reduced recurrence-free survival, compared to patients who had surgery <3 months (early surgery group) from the… More >

Abstract Introduction: There currently is no simple and reliable mechanism for Residency program directors to assess how well their trainees are being exposed to all spheres of their specialty. We report on the use of hand-held personal digital assistants (PDAs) to document all clinical and academic activities of urology residents at one academic institution.
Materials and methods: Software was developed to create customized pick lists allowing residents to record all activities on their individual PDAs. Categories included Adult Ambulatory, Pediatric Ambulatory, Adult Operative, Pediatric Operative, and Academic. Activities were subcategorized into detailed pick lists and time-tracking fields. Residents… More >

Abstract Introduction: Bladder cancer is the most common malignant tumor of the urinary system. Tobacco smoking has been implicated as a major risk factor for the development of bladder cancer and Nova Scotia has some of the highest smoking rates in Canada. We examined trends in the incidence of bladder cancer in Nova Scotia between 1980 and 1999.
Materials and methods: Data on incident cases of bladder cancer diagnosed in Nova Scotia over a twenty-year period (1980–1999) were obtained from the Nova Scotia Cancer Registry. The age-standardized incidence and mortality due to bladder cancer was calculated for both… More >

Abstract ith further advances in the technology of non-invasive imaging modalities as well as their utilization, diagnosis of incidental renal tumors has increased considerably. A large proportion of these renal tumors have been small (<4 cm) masses, for which nephron sparing surgery has been proven to be effective for. The trend toward minimally invasive options in the management of renal tumors has prompted interest in energy-based ablation techniques as a possible alternative to radical or partial nephrectomy in select patients. This article will review the natural history of small renal neoplasms and the emerging modalities of More >

Abstract A 56-year-old man presented with a 1-year history of intermittent gross, painless hematuria. Extensive evaluation revealed primary localized amyloidosis of the urinary bladder. Despite several endoscopic resections and fulgurations, the patient continued to have episodes of significant hematuria due to recurrent amyloid deposition. He was then successfully treated with partial cystectomy. At 60 months following surgery, the patient remains free of recurrent or systemic disease. More >

Abstract A 75 year-old uncircumcised man presented with a 1.1 mm thick malignant melanoma on the ventral aspect of the glans penis. He underwent isosulfan blue and technetium 99m guided sentinel lymph node (SLN) biopsy and distal penectomy with 2 cm margins. This is the third reported case of penile melanoma using both markers for SLN mapping. While frozen sections and H & E stains were negative, S-100 and HMB-45 immunohistochemistry revealed micrometastasis in one of the sentinel nodes. This case illustrates that any discussion with the patient about management and prognosis should await immunohistochemistry results. More >

Abstract Introduction and objective: The purpose of this study was to evaluate the cost-effectiveness of surgery versus collagen injection to treat female stress urinary incontinence after the failure of initial surgical treatment. The analysis was conducted from the health care system perspectives of Ontario and Quebec.
Materials and methods: A decision-tree was constructed to compare each of three surgeries (i.e., retropubic suspension, transvaginal suspension, sling procedures) with collagen. An average cost estimate was generated for each intervention, as was an incremental cost-effectiveness ratio for each surgery-collagen comparison.
Results: In both Ontario and Quebec, the treatment with the lowest average cost… More >
