Abstract Introduction: Endoscopic techniques are becoming increasingly accepted for treatment of vesicoureteric reflux as alternatives to open surgical reimplantation. However, there is some debate about the ideal injectable material. Since we have accumulated experience with several substances, an opportunity existed to compare them.
Materials and methods: From 1991 to 2003, 101 children with vesicoureteric reflux were treated by endoscopic subureteric injection either once (74) or twice (27) by either of two pediatric urologists. There were a total of 165 ureteral injections, 83 with polytetrafluoroethylene (Teflon®), 73 with polydimethylsiloxane (Macroplastique®), and 9 with collagen. Each child was evaluated pre-operatively… More >

Abstract Purpose: Historically adjuvant radiotherapy has been routinely recommended for stage I seminoma patients but surveillance has become an increasingly popular option over the last decade. We therefore decided to review the approach currently used by the radiation oncologists at our center.
Methods: A 14-item questionnaire evaluating physician opinions about treatment options for stage I seminoma patients was developed at the Ottawa Hospital Regional Cancer Centre (OHRCC). It was sent to all the radiation oncologists at OHRCC treating genitourinary (GU) malignancies for self-completion.
Results: All the GU radiation oncologists completed the survey for a response rate of 100% (7/7).… More >

Abstract Introduction and objective: The classical approach to the undergraduate medical clerkship has several limitations, including variability of clinical exposure and method of examination. As a result, the clerkship experience does not ensure exposure to and reinforcement of the fundamental concepts of a given specialty.
Materials and methods: This article reviews the classic approach to clerkship education within the undergraduate medical education. Specific attention is placed on clinical exposure and clerkship examination.
Results: We describe the introduction of the Core Learning Objective (CLO) educational model at the University of Chicago Section of Urology. This model is designed to provide an More >

Abstract Introduction: The NIH Chronic Prostatitis Symptom Index (CPSI) is recommended in the clinical evaluation of men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, its use is not possible in French speakers, as it has not been validated in this population. We performed a linguistic validation of the CPSI.
Methods: Linguistic translation followed the forward-backward-forward technique and relied on professional medical translators, bilingual health professionals, and patient input. Along with the SF-12, the translated version was administered to a convenience sample of men presenting for pre-vasectomy visits (controls) and to consecutive patients with established CP/CPPS (cases). Men… More >

Abstract Objectives: There is evidence of variation in both the processes and outcomes of prostate cancer care, resulting in possible harm to patients and increased costs to the health system. Care could be improved by first identifying critical, measurable indicators that correlate with quality of care. This work was conducted to develop indicators of prostate cancer care using a modified three-step Delphi approach.
Methods: A 17-member multidisciplinary panel reviewed potential indicators extracted from the medical literature through two consecutive rounds of rating followed by consensus discussion. The panel then prioritized the indicators selected in the previous two rounds.
Results:… More >

Abstract Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic inflammatory lesion of the kidney associated with both chronic infection and obstruction. Most common in middle-aged females, it is important to recognize in children because it may be confused with childhood renal malignancies particularly Wilms’ tumor. We report a case of a 1-year old male with antenatally detected and postnatally confirmed hydronephrosis. Further investigation revealed a left incomplete duplex collecting system with obstructing lower pole stones, pelvicaliectasis and widespread foci of calcification. He underwent a left nephroureterectomy with the pathological report noting XGP. More >

Abstract A 59 year old male presented with a 4 month history of lower urinary tract symptoms.
Exhaustive urological investigations revealed papillary tumors and carcinoma in situ extending from the prostatic urethra, throughout the bladder, up both ureters and into the renal pelves.
Tumors were resected where possible and then bacillus Calmette-Guèrin (BCG) and mitomycin C (MMC) were infused sequentially through bilateral nephrostomy tubes for a total of six BCG and three MMC instillations.
Follow up 1 month post treatment demonstrated a complete response which persisted for 2 years. Then there appeared a solitary papillomatous recurrence in the More >

Abstract Introduction: Management of vesical calculi in children poses an interesting challenge to the urologist. The treatment options currently available include open surgery, transurethral pneumatic cystolithotripsy, percutaneous suprapubic cystolithotomy and shockwave lithotripsy (SWL). Holmium:YAG (Ho:YAG) laser cystolithotripsy represents a novel modality of treatment that is minimally invasive.
Materials and methods: From July 1999 to January 2003 we treated 23 children with vesical calculi using transurethral Ho:YAG laser lithotripsy. The indications for cystolithotripsy were stone size ≤4 cm (N=19), or multiple stones with combined stone burden ≤4 cm (N=4). The mean patient age was 7.8 (range 2-12) years and… More >

Abstract Background: Assessment of prostate cancer (PCa) specific and generic health-related quality-of-life (HRQOL) is frequently omitted due to several obstacles, such as respondent burden and infrastructure-related limitations. We attempted to reduce the number of items of two commonly used HRQOL assessment tools, namely the UCLA PCa Index (PCI) and the RAND SF-12, with the intent of generating the most parsimonious, yet psychometrically valid and reliable HRQOL assessment tool.
Methods: The PCI and SF-12 were administered to 2415 radical prostatectomy patients, and re-tested in a convenience sample of 35 men with PCa. Multivariate linear regression models defined the most… More >

Abstract The genus Brachiaria (Trin.) Griseb. has achieved considerable importance to cattle production systems, as a result of the good production and adaptation of a few cultivars to poor and acid soils of the Brazilian savannas. Many of its species and accessions are polyploid and apomictic, which limits direct hybridization. To assist the breeding program, cytogenetic characterization has been undertaken on the accessions of Brachiaria collection at the Embrapa Beef Cattle Research Center. In this study, chromosome number and meiotic behavior are reported for the Brachiaria nigropedata (Ficalho & Hiern) Stapf collection. The 20 available accessions are tetraploid… More >
