Computerized Tomography Findings In Pediatric Renal Trauma - Indications For Early Intervention?
UroToday.com - The study out of Children's Hospital of Pittsburgh evaluated CT scans for blunt renal trauma to see if they correlated with the need for operative intervention when urinary extravasation was present.

A total of 17 patients with grade IV blunt renal trauma and urinary extravasation were identified between 2000 and 2007. Each CT scan was reviewed to determine location, size and number of sites of extravasation, as well as the presence of contrast material in the ipsilateral ureter. These were then compared to the findings at the time of surgery - whether surgey included stent placement, percutaneous urinoma drainage, angiographic embolization and nephrectomy.

Increased Risk Of Kidney Stone Disease Due To Global Warming, Predicts UT Southwestern Researchers
Global warming is likely to increase the proportion of the population affected by kidney stones by expanding the higher-risk region known as the "kidney-stone belt" into neighboring states, researchers at UT Southwestern Medical Center and UT Dallas have found.

Dehydration is one of the risk factors linked to kidney-stone disease, and the paper suggests global warming will exacerbate this effect. The researchers predict that by 2050, higher temperatures will cause an additional 1.6 million to 2.2 million kidney-stone cases, representing up to a 30 percent growth in some areas.

Information
Prostate cancer is the second leading cause of death among men. In 2002 it is estimated that 30,200 men will die from prostate cancer and 189,000 men will be diagnosed (American Cancer Society Facts & Figures 2002). The incidence of prostate cancer increases with age with 75% of all prostate cancers being diagnosed in men over the age of 65.

Prostate Cancer Management
The critical focus for the treatment of prostate cancer is to treat those cancers where it is necessary, and not to treat those that do not need it.

Decisions about the best management of prostate cancer can be complex and depend upon the:

Pathology of the cancer (unlike other cancers, prostate cancer often progresses very slowly)
Stage of the disease (non-metastatic (localized or locally advanced), metastatic or hormone refractory)
Age and general health of the patients at diagnosis
The impact that treatment can have on quality of life, including sexual activity.
Patient's preference for treatment
PSA at diagnosis

August is National Immunization Awareness Month
Vaccine-preventable disease levels are at or near record lows. However, we cannot take high immunization coverage levels for granted. To continue to protect America's children and adults, we must obtain maximum immunization coverage in all populations, establish effective partnerships, conduct reliable scientific research, implement immunization systems, and ensure vaccine safety.

Urethral Cancer

Overview

The urethra is the structure that carries urine, and in men, semen from the body. It is located within the penis (organ for reproduction and urination) in men and in front of the vagina (passageway to the uterus, birth canal) in women. Urethral cancer is rare and is often associated with invasive bladder cancer. It tends to metastasize (spread) to adjacent soft tissue and is often locally advanced when diagnosed.

Types

Different types of urethral cancer develop within different types of cells and in different portions of the urethra. In women, the urethra is lined with transitional cells near the urethral opening and squamous cells near the bladder. In men, transitional cells line the upper portion and squamous cells line the urethra at the base of and within the penis.

Squamous cell carcinoma develops in flat, scaly surface cells and is the most common type of urethral cancer. Other types include the following:

Transitional cell carcinoma (surface cells of the urethra)
Adenocarcinoma (develops in glands located near the urethra)
Melanoma (extremely rare; develops in pigment-producing skin cells)
Sarcoma (extremely rare; develops in blood vessels, smooth muscle, and connective tissue)

Urethral cancer that is superficial and located in the anterior portion of the structure (i.e., toward the urethral opening) often can be treated successfully. Cancer that develops in the posterior portion of the urethra (i.e., near the bladder) is usually invasive and rarely curable.

In women, urethral cancer often spreads to the labia, vagina, and bladder neck. In men, the condition may spread to the tissues of the penis and perineum, the prostate gland, the ligament that surrounds the urethra (urogenital diaphragm), the regional lymph nodes, and the penile and scrotal skin.

Incidence and Prevalence

Urethral cancer is more common in women. It can occur at any age, but the incidence is highest in patients in their 60s.

In men, 80% of cases are squamous cell carcinomas, most of which occur in the urethra at the base of the penis. In women, 60% of cases are squamous cell carcinomas.
