Physical activity may lower risk of prostatitis
September 1st 2006Atlanta-Because prostatitis in African-American men is not well studied, University of Michigan researchers examined the prevalence and risk factors in African-American men in Genessee County, MI, with a surprising result. On the whole, the risk factors matched those reported for Caucasian populations, but men who were physically active had significantly decreased odds of having prostatitis in a study presented at the AUA annual meeting.
Targeted RCC therapies create new role for urologists
September 1st 2006Within the past year, enormous strides have been made in the treatment of renal cell carcinoma, particularly in the pharmacotherapeutic arena. To date, two new drugs have received FDA approval, and other promising agents are in development. As research provides new insights into the nature of RCC and its treatment, the role of the urologist in patient management is evolving quickly.
Advanced prostate Ca patients with worsening anemia may face poorer outcomes
August 16th 2006Shortened survival and earlier relapse have been reported in men with advanced prostate cancer whose hemoglobin levels decline during the first 3 months of hormone therapy, according to a study published in Cancer (2006; 107:489-96).
RP may offer survival benefit over other treatments in T4 disease
August 16th 2006Survival rates appear to be better in patients with clinical T4 prostate cancer after radical prostatectomy than in patients receiving only radiation therapy or hormone therapy, according to a study by researchers at Emory University in Atlanta.
Change in Western diet may reduce PSA levels, prostate cancer growth
August 16th 2006If the fatty acid ratio found in the typical Western diet is changed to include more omega-3 fatty acids and fewer omega-6 fatty acids, then prostate cancer tumor growth rates and PSA levels may decrease, according to a preclinical study published recently in Clinical Cancer Research (2006; 12:4662-70).
Prospective analysis: PCNL safe, effective overall
August 15th 2006Atlanta-Results of a prospective, multivariate analysis to identify predictors of perioperative course and clinical outcomes in patients undergoing percutaneous nephrolithotomy (PCNL) for extensive stone disease support the conclusions that in high-volume centers, the safety and efficacy of the procedure are excellent and that they are not significantly influenced by patient-related or sociocultural/ethnic factors.
Study shows route of bladder antigens to lymph tissues
August 15th 2006Atlanta-Bladder antigens travel to local and distant lymphoid tissues and enter the circulation, where they can travel as far as the spleen, according to results of a new study from the Feinberg School of Medicine at Northwestern University, Chicago. The study, which the authors say is the first functional study of antigen trafficking from the bladder, may further researchers' understanding of bladder cancer immunotherapies and potentially aid in the development of a vaccine for urinary tract infections.
Recurrent UTIs may be tied to host immune suppression
August 15th 2006Atlanta-Evading host immune response may enable uropathogenic Escherichia coli (UPEC) to establish reservoirs in the bladder that lead to recurrent urinary tract infections, according to David Klumpp, PhD, assistant professor of urology at the Feinberg School of Medicine, Northwestern University, Chicago.
Five compounds show potential in OAB, pain syndromes
August 15th 2006Atlanta-Five new compounds-none an antimuscarinic and all in different classes-are showing potential for overactive bladder. They may also have applications in BPH, chronic prostatitis/chronic pelvic pain syndrome, and painful bladder syndrome/interstitial cystitis (PBS/IC).
PDE-5 inhibitors, antimuscarinics may play role in BPH
August 15th 2006In men with BPH, drugs indicated for other urologic conditions may play a role in the treatment of their lower urinary tract symptoms, suggest data from a number of studies presented at the 2006 AUA annual meeting. These studies were among those on BPH and LUTS highlighted by Claus G. Roehrborn, MD, professor and chairman of the department of urology at the University of Texas Southwestern Medical Center, Dallas.
Stone fragment culture may guide antimicrobial Tx
August 15th 2006The take-home messages on infection/inflammation at the AUA annual meeting covered a spectrum of urological conditions, including stone disease, urinary tract infection, urethritis, and interstitial cystitis. Results from both clinical studies and laboratory research have potential implications for urologists in their evaluation and management of patients with these disorders, said Anthony J. Schaeffer, MD, Herman L. Kretschmer professor and chairman, department of urology, Feinberg School of Medicine, Northwestern University, Chicago.
ED, stroke risk confirmed; ED, NAION risk refuted
August 15th 2006Urologists attending this year's AUA annual meeting found that erectile dysfunction raises the risk of stroke and heart disease, testosterone is safe in older men, phosphodiesterase type-5 inhibitors do not appear to induce an ocular disorder known as nonarteritic anterior ischemic optic neuropathy (NAION), and aggressive antiseptic washout reduces penile prostheses infections.
Comestibles fan IC fires; dietary guidance advised
August 15th 2006Atlanta-Diet does make a difference in symptoms in patients with interstitial cystitis. Most IC patients and the urologists who specialize in treating them are aware that certain foods, beverages, and supplements exacerbate IC symptoms, and a few ease them. Evidence for this has been sketchy and anecdotal, and a study presented at the 2004 AUA annual meeting cast doubt on that common wisdom by demonstrating that instillation of solutions from pH 5 to 7.5 had no effect on symptoms.
Familiar biomarker may predict RCC metastasis
August 15th 2006Worcester, MA-An off-the-shelf test for an already-identified biomarker may emerge as a quick, simple, and affordable screen for aggressive renal cell carcinoma. Clinicians may soon be able to identify their highest-risk kidney cancer patients and begin aggressive treatment earlier in the course of their disease.
