Abstract Objective: A multidisciplinary panel of experts from Canada and the United States was convened by the Ontario Neurotrauma Foundation (ONF) to establish research priorities in the area of urological care following spinal cord injury (SCI).
Design: The panel reviewed a synthesis of published literature in five areas of urology, identified emerging opportunities in the private and public sector, and used a modified Delphi approach to reach consensus on priorities for funding.
Results: The panel recommendations included: clinical trials of the safety and efficacy of M3 receptor specific anti-muscarinic agents for bladder hyperactivity in SCI patients; development and… More >

Abstract Objective: To assess the relationship of nocturia and sleep to body weight.
Materials and methods: A questionnaire survey among all (n=10216) members of a pensioners' association in the Swedish counties of Västerbotten and Norrbotten.
Results: A total of 6103 evaluable questionnaires were received, of which 39.5% were from men. The response rate was 61.3%. The ages of the male and female participants were 73.0 (6.0) [mean (SD)] and 72.6 (6.7) years, respectively. Body mass index (BMI) was 25.4 (3.1) in men and 25.4 (3.7) in women. BMI increased in parallel with increasing number of nocturnal micturition episodes More >

Abstract Introduction: Accurate clinical staging is critical in guiding treatment for patients with prostate adenocarcinoma. Endorectal magnetic resonance imaging (MRI) has been advocated to improve staging accuracy. In order to assess the learning curve for endorectal MRI interpretation, we compared two cohorts of patients with high-risk prostate who underwent endorectal MRI at a center with limited prior exposure to this imaging modality.
Materials and methods: Data for all patients who received a preoperative endorectal MRI followed by radical prostatectomy were prospectively collected. MRI was performed in patients with a high level of suspicion for extracapsular disease based on… More >

Abstract Introduction: Leiomyosarcoma of the kidney and renal pelvis is a rare tumor that, on the basis of limited data, has been ascribed a particularly poor prognosis compared to other subtypes of renal malignancy. Here the population-based Surveillance, Epidemiology, and End Results (SEER) registry is used to study the survival of renal leiomyosarcomas.
Methods: There were 95,935 cases of invasive cancer of the kidney and renal pelvis retrieved from the SEER registry to provide 112 cases of leiomyosarcoma. Kaplan-Meier survival estimates and Cox proportional hazard models were constructed to compare the survival of leiomyosarcomas to other renal… More >

Abstract Purpose: Bladder cancer is the fourth most common cancer in men and the ninth most common cancer in women. Bladder is not a common site for metastasis of cancer and often goes undiagnosed in the clinical follow up of patients with cancer. We reviewed the literature for published reports on metastatic cancer involving bladder.
Materials and methods: We searched MEDLINE, PubMed and OVID from 1953 to June 2005 for published reports on metastatic cancer involving bladder. The key words used were bladder, cancer and metastatic. A total of 2405 abstracts were reviewed. All relevant articles reporting metastatic… More >

Abstract Purpose: Complete urethral reconstruction in women is an extreme challenge for urologists. We report a new approach to this challenging procedure, using a modified neurovascular pudendal thigh flap (Singapore flap) for neo-urethral reconstruction in two patients at our institution.
Materials and methods: A Singapore flap was raised and transposed to the vagina in two patients with destroyed urethras following several previous uro-gynecologic procedures. In one case, the flap was tubularized distally and anastomosed proximally to the bladder neck. In the second case, the flap served to cover a urethroplasty inlay.
Results: We are presently reporting mainly on… More >

CASE REPORT

Abstract This report describes an illustrative case of malignant pheochromocytoma of the urinary bladder in a 28-year old man. A combined-modality treatment plan with partial cystectomy and post-operative radiotherapy and concurrent chemotherapy with single agent cisplatin weekly was performed. Three weeks after completing concurrent chemoradiation the first of four planned cycles of cisplatin 25 mg/m² andetoposide 100 mg/m² was administered daily over 3 days. Although there are no controlled series offering proof of benefit, postoperative concurrent chemoradiation followed by chemotherapy alone are reasonable options for patients with residual disease or at high risk for locoregional relapse.

Abstract Bone metastasis is usually a late manifestation in patients with germ cell tumors and a poor prognosis site. We report a case of 29-year-old man with a nonseminomatous germ cell tumor who presented with a single metastatic site in a vertebrae with spinal compression. He was treated with a left orchiectomy and four cycles of chemotherapy containing bleomycin,etoposide, and cisplatin. He attained complete remission. More >

Abstract Urethral diverticula are sac like dilations of the urethra and are classified as either congenital or acquired. While diverticula are commonly seen in female patients, they are rarely seen in men. The most common etiologies of male acquired diverticula include urethral trauma, stricture, abscess or post-hypospadias repair. We report a case of an acquired urethral diverticula secondary to unrepaired penile fracture and urethral injury and review the literature on the topic. More >

Abstract We describe a case of right renal agenesis with ipsilateral ectopic ureter opening into a large seminal vesicle cyst in a 24-year old man. The patient presented with left flank pain and the imaging studies showed absent right kidney and a large pelvic cyst possibly arising from seminal vesicle. The cyst was removed together with the right ureter and kidney remnant through a laparotomy. More >

Abstract The combination of Mohs micrographic surgery and sentinel lymph node biopsy in the treatment of penile melanoma is novel. Mohs surgery allows the removal of penile malignancies with microscopically controlled tumor-free borders, while maintaining cosmetic and functional demands through the maximal preservation of normal tissue. Sentinel lymph node biopsy minimizes the morbidity associated with inguinal node dissection. At 30 months follow-up, these two modalities together have achieved local control and regional nodal staging while minimizing functional morbidity. More >

Abstract Purpose: In adults renal cell carcinoma (RCC) accounts for over 85% of all diagnosed renal cancers. A much more rare and aggressive malignant tumor of the kidney is angiosarcoma (AS) with less than 25 cases described internationally. Both RCC and AS have similar radiological appearances and thus require histological evaluation for definitive diagnosis. We present a case of renal AS in a 63-year old male who was initially radiologically diagnosed as RCC, and review the current renal AS literature.
Methods: The current English literature from 1981 and onwards on renal AS was reviewed and compared to our… More >
