For men with prostate cancer, radiation seed implants may yield a better short-term side effect profile than surgery, but surgery may offer slightly better long-term outcomes, new research from French radiation oncologists indicates.
More than 90% of men who receive appropriate radiation dose levels with permanent radiation seed implants to treat their prostate cancer are cured of the disease 8 years after diagnosis, according to a recent study in the International Journal for Radiation Oncology Biology Physics (2007; 67:327-33).
Atlanta—Tissue engineering research has grown by leaps and bounds in the past decade and a half, yielding findings that may someday have a profound impact on the field of pediatric urology. At the 2006 American Academy of Pediatrics Section on Urology annual meeting here, several groups presented cutting-edge data on novel systems for organ generation, including research demonstrating the feasibility of generating a functioning bladder from stem cells.
Three-fourths of men treated with a combination of radiation seed implants and external beam radiation therapy for prostate cancer are cured of their disease 15 years following their treatment, according to a study published in the International Journal of Radiation Oncology*Biology*Physics (2007; 67:57-64).
Patients who have undergone gastric bypass surgery for morbid obesity have increased risk factors for the formation of kidney stones, according to a study by Mayo Clinic researchers.
Ann Arbor, MI—Surgeon age is not a significant predictor of risk of mortality after cystectomy, according to the results of a recently published study from researchers at the University of Michigan, Ann Arbor (Ann Surg 2006; 244:353-62).
Uroplasty, Inc. has received an approvable letter from the FDA relating to its pre-market approval application for Macroplastique implants for the treatment of female stress urinary incontinence.
Spencer, IN—Cook Urological's 1.7F NCompass Nitinol Stone Extractor features a tipless 16-wire dual basket design that securely traps and extracts kidney stones and stone fragments as small as 1.5 mm without impeding irrigation or visibility during the procedure. Made from the shape-memory alloy of titanium and nickel, nitinol, the extractor's design minimizes tissue trauma and provides stability and ease of movement during procedures, according to Cook.
As lifestyle choices influence the incidence of stone disease, shockwave lithotripsy appears to be losing ground as a treatment option for patients with stones of certain compositions and stones located in hard-to-reach places.
Atlanta—After nearly 30 years of using dermal grafts for reconstruction in Peyronie's disease, Gerald H. Jordan, MD, is switching to porcine small intestinal submucosa (SIS) as the preferred material. It was a studied decision.
