Abstract Objectives: The study evaluates the effect of chronic usage, beyond the recommended maintenance schedule, on the efficacy of electromagnetic lithotripter. To our knowledge, there is no publication investigating the effect of chronic usage on the electromagnetic lithotripter, despite the maintenance schedule established by the manufacturers. Our goal is to verify if the acoustic parameters of the shock wave changed with usage, and if this change could be associated with change in clinical efficacy.
Methods: This study lasted 18 months. Every 6 months the lithotripter's efficacy was evaluated in two ways: objectively and clinically. Objective efficacy was… More >

Abstract Objective: Testicular cancer is a highly curable malignancy of young men. Appropriate and timely management is critical to ensure optimal clinical outcomes. A 3-year population-based review of testicular cancer patients in Manitoba, Canada was undertaken to evaluate our management patterns.
Methods: Men diagnosed with testicular cancer from 1998 to 2000 were identified from the Provincial Cancer Registry. Chart review was utilized to collect information on demographic characteristics, timelines of diagnostic and staging investigations, completeness of pathology reports, management, and outcomes.
Results: Seventy-eight men were identified with 80 testicular cancers: 46 (59%) patients had 48 seminomas and 32… More >

Abstract Objective: Several investigators have noted that previous inguinal hernia repair with or without the use of prosthetic mesh might be a relative contraindication for open or laparoscopic radical prostatectomy due to the presence of adhesions and the difficulty of tissue dissection. We aimed to evaluate the impact of previous hernia repair on the performance and feasibility of robotic prostatectomy.
Materials and methods: We performed a retrospective analysis of 354 patients who underwent robotic prostatectomy at our institution. The three patient groups were: 292 patients who had no prior hernia repair (group 1), 50 patients who had prior… More >

Abstract The use of radiation therapy in the radical treatment of prostate cancer can lead to potential acute and long-term toxicity and health-related quality-of-life (HRQoL) changes. Ongoing investigation into dose-escalation, dose-per-fraction escalation, new radiation treatment technology/ paradigms, and novel systemic therapy may have either positive and/or negative effects on normal tissue toxicity/ HRQoL. Herein, common toxicity scales and HRQoL instruments that attempt to describe the deleterious effects of prostate radiation therapy are reviewed. More >

Abstract Introduction: Interstitial cystitis (IC) is a potentially severe and debilitating condition of the bladder. Numerous factors have been implicated in its pathogenesis.
Materials and methods: A literature review was conducted on the following topics: urothelium, mucosal lining, interstitial cystitis, bladder, and glycosaminoglycans.
Results: A commonly proposed cause for IC is a defect or alteration in the bladder surface leading to increased permeability to noxious urinary solutes and ultimately to tissue inflammation and neurogenic upregulation. Support for this concept is drawn from studies of the structure, function, and composition of the bladder surface. The cause(s) of this alteration More >

Abstract Objective: We present a child with Denys-Drash syndrome recognized after surgery for mixed gonadal dysgenesis, and discuss screening procedures the urologist should consider in similar circumstances.
Case report: A 1-year-old child with XY gonadal dysgenesis underwent genital reconstruction. The postoperative period was complicated by incisional drainage, which led to the recognition of a nephrotic syndrome. Molecular analysis of the WT-1 gene confirmed a mutation associated with the Denys-Drash syndrome.
Conclusion: The Denys-Drash syndrome should be suspected in children with XY gonadal dysgenesis. The presence of urine protein should be sought in such children, and if present, consultation More >

Abstract Introduction: To date, no study has compared postoperative pain and requirement for pain medications in open versus robot-assisted radical cystectomy. Patient reported pain and opiate use were reviewed retrospectively using prospectively collected data from postoperative day one to day of discharge.
Materials and methods: Twenty consecutive robot-assisted radical cystectomy patients were compared to the prior 20 patients who underwent open radical cystectomy. Data was collected prospectively to determine opiate requirements and pain scores in each group. Daily opiate use was converted to morphine sulfate equivalents (MSE) to facilitate comparison. A Likert pain perception scale was used to… More >

Abstract A new disease of Spathiphyllum wallisii plants, characterized by leaf yellowing and wilting due to root and crown rot, was observed in nurseries of the Great Buenos Aires, Argentina. A fungus was consistently isolated from diseased tissue and identified as Cylindrocladium spathiphylli, on the base of its morphological and cultural characteristics. Inoculation tests were carried out which confirmed this fungus as the causal agent of the disease. This is the first report of C. spathiphylli causing root and crown rot of S. wallisii in Buenos Aires. More >
