Zinner's syndrome: Case report of a rare maldevelopment in the male genitourinary tract.

Zinner syndrome is a rare congenital malformation of the urogenital tract. It is due anomaly in the developmental of Wolffian duct. Zinner syndrome comprises triad of seminal vesicle cyst, unilateral renal agenesis and ipsilateral ejaculatory duct obstruction.

Unusual Presentation, Relapse, and Metastasis of a Pediatric Testicular Yolk Sac Tumor: Case Report.

Testicular tumors are not uncommon in children and represent 1%-2% of all pediatric malignancies. Prepubertal testicular yolk sac tumor is the most common childhood testicular cancer, accounting for 70%-80% of all cases. The clinical presentation varies from one patient to another; most common presentation is painless scrotal mass.

Small Renal Mass Surveillance: Histology-specific Growth Rates in a Biopsy-characterized Cohort.

Background: Most reports of active surveillance (AS) of small renal masses (SRMs) lack biopsy confirmation, and therefore include benign tumors and different subtypes of renal cell carcinoma (RCC).

Objective: We compared the growth rates and progression of different histologic subtypes of RCC SRMs (SRM) in the largest cohort of patients with biopsy-characterized SRMs on AS.

Design, Setting, And Participants: Data from patients in a multicenter Canadian trial and a Princess Margaret cohort were combined to include 136 biopsy-proven SRM lesions managed by AS, with treatment deferred until progression or patient/surgeon decision.

Identification of tumor size as the only factor associated with nondiagnostic biopsies in patients with small renal masses.

Introduction: As greater numbers of small renal masses (SRMs) are discovered incidentally, renal tumor biopsy (RTB) is an increasingly recognized step for the management of these lesions, ideally for the prevention of surgical overtreatment for benign disease. While the diagnosis can often be obtained preoperatively by RTB, indeterminate results create greater difficulty for patients and clinicians. This study examines a series of RTBs, identifying the portion of these that were able to yield a diagnosis, and correlates patient factors, including RENAL and PADUA scoring, with the outcome of a non-diagnostic result.

Classification tree for the prediction of malignant disease and the prediction of non-diagnostic biopsies in patients with small renal masses.

Introduction: Preoperative prediction of benign vs. malignant small renal masses (SRMs) remains a challenge. This study: 1) validates our previously published classification tree (CT) with an external cohort; 2) creates a new CT with the combined cohort; and 3) evaluates the RENAL and PADUA scoring systems for prediction of malignancy.

Hospitalizations to Manage Complications of Modern Prostate Cancer Treatment in Older Men.

Objective: To assess rates of treatment-related hospitalizations following surgery and radiotherapy in the treatment of clinically localized prostate cancer, given the importance of hospitalizations in healthcare resource utilization.

Methods: We conducted a population-based retrospective cohort study of patients aged 65-79 years receiving radical prostatectomy (open or minimally invasive) or radiotherapy (brachytherapy or external beam) from 2001 to 2008 in the Surveillance, Epidemiology & End Results-Medicare linked databases. We assessed treatment-related hospitalizations.

Effect of radical prostatectomy surgeon volume on complication rates from a large population-based cohort.

Introduction: Surgical volume can affect several outcomes following radical prostatectomy (RP). We examined if surgical volume was associated with novel categories of treatment-related complications following RP.

Methods: We examined a population-based cohort of men treated with RP in Ontario, Canada between 2002 and 2009.

The Need for Survivorship Care in Genitourinary Cancers: Considerations from SUO and LUGPA.

Introduction: A quarter of American cancer survivors have genitourinary malignancies that are largely managed by urologists. We explored urologist perceptions about survivorship care for genitourinary malignancies.

Methods: A total of 701 SUO (Society of Urologic Oncology) and 1,746 LUGPA (Large Urology Group Practice Association) members were invited to complete a web based survey composed of 5 domains, including 1) demographics, 2) current survivorship care practices, 3) perceived barriers, 4) accessibility to survivorship resources and 5) perceptions of advocacy groups.

New Rates of Interventions to Manage Complications of Modern Prostate Cancer Treatment in Older Men.

Background: Interventions to treat complications from prostate cancer (PCa) treatment are common and affect the course of a patient's life.

Objective: To examine rates of complications other than urinary incontinence and impotence for older patients treated for PCa.

Design, Setting, And Participants: Population-based retrospective cohort study of patients aged 65-79 yr receiving radical prostatectomy or radiotherapy (RT) from 2001 to 2008 in the US Surveillance Epidemiology and End Results and Medicare linked databases.

Practice patterns and perceptions of survivorship care in Canadian genitourinary oncology: A multidisciplinary perspective.

Introduction: There is little knowledge of survivorship care specific to genitourinary (GU) cancers. To improve care delivery to this patient population, we need to clearly define physician perceptions of survivorship care. We therefore conducted a study to determine the challenges to GU cancer survivorship care in Canada.

Diagnosis and treatment of small renal masses: the role for molecular biology.

Renal cell carcinoma (RCC), the most common type of kidney cancer, is increasing in incidence and is the most lethal genitourinary cancer. Due to the increasing use of abdominal imaging, incidentally detected, asymptomatic small renal masses (SRMs), most of which are RCC, have become the most common presentation of kidney cancer. Most RCC SRMs initially grow slowly or not at all, but others progress to advanced and metastatic cancer.
