Philadelphia--Urologists who manage patients with overactive bladder are challenged not only with choosing from a growing list of pharmacologic treatment options, but also with the prospect that some patients may not respond to oral anticholinergic treatment at all. In these patients with "refractory detrusor overactivity," it is important to realize that a number of factors mitigate against successful therapy, said Roger R. Dmochowski, MD, professor of urology at Vanderbilt University Medical Center, Nashville, TN.
Houston--Nuclear matrix protein 22 (NMP22) is to bladder cancer as PSA is to prostate cancer, perhaps better. That is the implication of a recently published, prospective, multi-institution study showing the point-of-care NMP22 assay (BladderChek, Matritech, Newton, MA) has a sensitivity of 55.7% and a specificity of 85.7%. In contrast, cytology was found to have lower sensitivity (15.8%) but higher specificity (99.2%).
If we do not develop our own performance measures, someone else will do it for us.
Washington--A controversy is brewing over whether Medicare should pay for erectile dysfunction drugs, which boiled over in the midst of heated discussions over the cost of the new Medicare drug benefit.

San Francisco--Environmental factors have emerged as potential contributors to genetic anomalies affecting male genitalia, according to studies reported at the American Academy of Pediatrics Section on Urology annual meeting.
Honolulu--Men with local-regional prostate cancer following radical prostatectomy appear to have a more durable response to subsequent salvage radiotherapy than those patients with fossa-only or no disease following the operation, a new study shows. This finding is in direct contrast to what would normally be expected, said Inger Rosner, MD, a resident at Walter Reed Army Medical Center, Washington, working with David G. McLeod, MD.
Honolulu--Young men with early-stage, low-grade prostate cancer may defer therapy and elect watchful waiting without fear of clinically worse pathologic outcomes, according to results of an analysis conducted by urologists at eight different U.S. military medical centers.

PVP engenders minimal morbidity while achieving significant cost savings, said study author Robert E. Reiter, MD.
Honolulu--A new "one-step" percutaneous access sheath may become the next advance in the evolution of percutaneous nephrostolithotomy, according to D. Duane Baldwin, MD, associate professor of urology at the Loma Linda (CA) University Medical School. Dr. Baldwin has completed the first trials of the device, which weds the dilation balloon to the sheath, allowing the instrument to be advanced to the kidney in a single procedure.
Honolulu--Not only does a form of microwave thermotherapy for BPH appear to be free of sexual side effects, it may actually improve sexual function in men with the disease, investigators from the Portsmouth (VA) Naval Hospital and Eastern Virginia Medical School reported at the Kimbrough Urological Seminar here.
Honolulu--Operation Iraqi Freedom sees its share of sick and wounded soldiers. Primarily, specialists in orthopedics and general surgery are seeing an upswing in patients coming from the conflict.
