Abstract Purpose: Nephrogenic rests (NR) are clusters of cells similar to renal blastema. NR are frequently seen in kidneys with Wilms' tumor (WT) and are seen with higher frequency in nephrectomy specimens from obstructed and/or multicystic dysplastic kidneys (MCDK) compared to autopsy series of normal kidneys. The significance of NR and their role in tumorigenesis is largely unknown. We report the findings of two cases with NR associated with ureteral ectopy/obstruction and review the relevant literature.
Materials and methods: Two cases of upper pole heminephrectomy associated with ectopic upper pole ureter and resultant hydronephrosis were found to have… More >

Abstract Purpose: To compare patient reported pain during TRUS guided biopsies using intrarectal lidocaine gel versus lubricating gel.
Materials and methods: From May 2000 to May 2001, 360 men undergoing transrectal prostate biopsy were enrolled in this study. Patients were randomized into two groups. In group 1, 180 patients received 10 cc of 2% intrarectal lidocaine gel (Xylocaine® 2% jelly, Astra Pharma Inc.) 5 to 10 minutes before the procedure and in group 2, 180 patients received 10 cc of lubricating gel. No other sedation or analgesia was given. Pain level immediately after the last biopsy was assessed More >

Abstract Objective: To assess the temporal trend in surgical treatment of benign hypertrophy of the prostate in Sweden, particularly the possible influence of nocturia on the probability to be treated by a transurethral resection operation of the prostate (TURP).
Materials and methods: There were 2501 elderly men recruited by a questionnaire from a group of pensioners (n=4035; response rate 62%). Their age was 73.3 (6.4) years. The questionnaire included questions on their health and diseases, drugs, sleep habits and the number of nocturnal voiding episodes. Data on deaths from July 1, 1992 to December 31, 1997 were obtained.
Results:… More >

Abstract Erectile dysfunction has undergone dramatic advances in diagnosis and therapeutics over the past decade. Increasing numbers of men are currently seeking medical help for their sexual concerns, often from primary health care providers.
The Canadian Urological Association (CUA), Guidelines Committee is charged with the responsibility of creating practice guidelines for urologic conditions with the goal of improving physician knowledge and enhancing patient care. These Erectile Dysfunction Guidelines highlight the evolving use of a minimally invasive patient self­directed goal oriented approach to evaluation and treatment using oral agents as first-line therapy based on efficacy, side effect More >

Abstract The diagnostic rate of small, "incidental" tumors which are amenable to local excision or ablation has increased significantly due to widespread use of non-invasive body imaging tests. The role of nephron-sparing tumor­ablative surgery has expanded beyond the traditional circumstances of neoplasms in solitary/functionally solitary kidneys or tumors present bilaterally. Due to technologic advances, possible therapeutic options now include open surgery, laparoscopic, percutaneous and extraciorporeal approaches, in addition to surveillance in some cases. This review will concentrate on the new energy sources available for tumor ablation rather than the different surgical approaches, with a detailed review More >

Abstract Herein we report a rare combination of two urological tumors simultaneously: renal cell carcinoma of the kidney and transitional cell carcinoma of the bladder. A 67 year old male presented with hematuria. He was diagnosed with left renal cell carcinoma and transitional cell carcinoma of the bladder. Subsequently this patient underwent left nephrectomy (palliative) to control the pain and transurethral resection of bladder tumor. The clinical picture, radiographic and histological finding are presented, as well as the treatment offered. More >

Abstract We describe a case of salt-losing congenital adrenal hyperplasia due to 21-hydroxylase deficiency complicated by a right adrenal adenoma. The development of adrenal adenoma or carcinoma in-patients with congenital adrenal hyperplasia (CAH) is rare; the etiology is not clear but is thought to be related to inadequate glucocorticoid therapy. Tumor formation is postulated to be a consequence of ACTH hypersecretion, which results from the lack of glucocorticoid synthesis. Our patient underwent clitorectomy and multiple constructive procedures as a newborn baby; she was managed with hormone replacement for many years. However while she took adequate mineralocortocoid More >

Abstract Purpose: To determine, from a societal perspective, the effectiveness and cost effectiveness of concentrated cranberry tablets, versus cranberry juice, versus placebo used as prophylaxis against lower urinary tract infection (UTI) in adult women.
Materials and methods: One hundred fifty sexually active women aged 21 through 72 years were randomized for one year to one of three groups of prophylaxis: placebo juice + placebo tablets versus placebo juice + cranberry tablets, versus cranberry juice + placebo tablets. Tablets were taken twice daily, juice 250 ml three times daily. Outcome measures were: (1) a >50% decrease in symptomatic UTI's… More >
