Abstract A steady decline in androgen levels occurs in males as they age. Evidence suggests that this decline may be at least partially responsible for a variety of physical and mental changes associated with the aging process. For instance, abnormally low levels of androgens can lead to profound changes in bone density, body composition, as well as sexual and cognitive function. Testosterone replacement has been shown to produce improvements in many of these areas. However, this practice is not without risks, both proven and theoretic. Also, the diagnosis of androgen deficiency and the decision to treat More >

Abstract A water quality index as a standardized method to compare the category in an integral way, between locations and through time, of the different water, river and stream storages of the Amajac river basin was developed. In addition, it is possible to predict the degree of contamination and establish planning strategies in the management of the water resources for the river basin in issue. The used methodology was based in the quantitative expression of water quality. Three samplings were made (2005-2006) and Dissolved Oxygen, Coliform in feaces, pH, Oxygen Biochemical Demand, Nitrates, Total Phosphorus, Turbidity… More >

Abstract The European Randomized Study of Screening for Prostate Cancer (ERSPC) is a large, randomized controlled trial of screening versus control, conducted in eight European countries (Belgium, Finland, France, Italy, the Netherlands, Spain, Sweden, and Switzerland). This article focuses on important aspects relating to recent findings from the ERSPC about two topics: first, leadtime and overdiagnosis, and second, prostate-specific antigen (PSA) as a test for repeated screening.
The ERSPC together with the prostate cancer arm of the Prostate, Lung, Colon and Ovary (PLCO) screening trial of the National Cancer Institute in the United States are set to… More >

Abstract Introduction: Phimosis is defined as the inability to retract the foreskin. Differentiating between physiological phimosis and pathological phimosis is important, as the former is managed conservatively and the latter requires surgical intervention. Referrals of patients with physiological phimosis to urology clinics may create anxiety regarding the need for surgery amongst patients and parents, while unnecessarily expanding the waiting list for specialty assessment.
Objectives: To determine the ability of referring physicians to differentiate physiological from pathological phimosis, and to see whether there is any difference in this ability between generalists versus specialists.
Materials and methods: A retrospective chart review… More >

Abstract Objective: To develop the first Canadian guidelines for the management of lower urinary tract symptoms in men with benign prostatic hyperplasia (BPH).
Methods: These guidelines, developed under a mandate provided by the Canadian Urological Association (CUA), were a collaborative effort between the CUA guidelines committee and the Canadian Prostate Health Council. BPH guidelines developed by the American Urological Association, the European Association of Urology, the World Health Organization International Consultation on BPH, and similar committees from Germany, Sweden and Australia were reviewed. The committee further reviewed a systematic literature search, updated to May 2004, and systematically derived… More >

Abstract We present a case of a pathologic stage 1, right sided, non-seminomatous germ cell tumor recurrence in the left seminal vesicle, 20 years after initial diagnosis and treatment. The patient was treated with three salvage cycles of bleomycin, etoposide, and cisplatinum. At 24 months of follow-up after completion of chemotherapy, digital rectal and TRUS examinations revealed complete resolution of the lesion. We believe that this tumor is a late metastasis to the contralateral seminal vesicle. More >

Abstract A 24 year old uncircumcised man presented with a 1 month history of a painful, fungating lesion on his glans penis. Following biopsy, and further clinical developments, a diagnosis of Wegener’s Granulomatosis (WG) was made. The penile lesion was treated with surgical debridement, and a penile stump was salvageable. This is only the fourth case of WG initially presenting with a penile lesion to be reported in the literature. More >

Abstract Objectives: To compare the effectiveness of two rapid urine tests fibrinogen / fibrin degradation products FDP (Aura Tek FDP, PerImmune Inc., Rockville, Maryland, USA) and bladder tumor antigen BTA (Bard BTA, Bard Canada Inc., Mississauga, Ontario, Canada) to urinary cytology in establishing the diagnosis of transitional cell carcinoma (TCC) in patients with suspected upper tract malignancy.
Materials and methods: In a prospective study, urine samples were collected from 29 patients with abnormalities of the upper tracts highly suspicious for malignancy. Sensitivity and specificity of the BTA and FDP tests were determined and compared to those of cytology.… More >

Abstract exploration was not performed and a period of watchful waiting with evolution control by ultrasonography was decided. Results: After a 3 month follow-up, the ultrasonography control revealed a total re-vascularization of the vessels and a reduction of the lesion size. Conclusion: The authors suggest that the combination of ultrasonography and MRI, in the management of testicular infarction, may avoid invasive surgery. More >

Abstract Introduction: The conservative management of multicystic dysplastic kidneys (MCDK) has been very successful, largely due to advances in diagnostic imaging. Classically, MCDK is described as a non-functioning cystic renal mass. However, we noticed that the increasing sensitivity of renal scans is able to demonstrate function in MCDK that previously would not have been detected.
Methods: We describe eight cases of MCDK with elements of function on renal scan, and their follow up.
Results and conclusions: One half (4/8) of these children underwent nephrectomy, and histology was consistent with MCDK. The remaining 4/8 were successfully followed to radiographic involution, More >
