Biomarker test may improve prostate cancer diagnosis
March 2nd 2005A test for the urinary biomarker thymosin beta15 (Tbeta15), in combination with PSA testing, can improve both the sensitivity and specificity of prostate cancer diagnosis, according to a study published in the online edition of Prostate (Jan. 21, 2005).
Quinolone is more effective than amoxicillin-clavulanate for uncomplicated UTI
March 2nd 2005The fluoroquinolone ciprofloxacin (Cipro) appears to be more effective than amoxicillin-clavulanate (Augmentin) as a treatment for acute uncomplicated urinary tract infections in women, even in those infected with susceptible strains, according to a study published in last week's JAMA (2005; 293:949-55).

March 2nd 2005APC8015 (Provenge), an investigational form of immunotherapy, significantly improves survival in men with asymptomatic, metastatic androgen-independent prostate cancer compared with patients receiving placebo, according to a study being hailed as the first to show a survival benefit with a vaccine in patients with advanced prostate cancer.
Stone-free rates improve with access sheaths
March 1st 2005Mumbai, India—Overall stone-free rates are significantly improved in patients with renal calculi who undergo ureteroscopy using a ureteral access sheath compared with those treated without access sheaths, report researchers from Duke University, Durham, NC. Stone-free rates are improved for calculi in all portions of the kidney, they said during a presentation at the World Congress on Endourology.
When and how to perform lap pyeloplasty for UPJ obstruction
March 1st 2005The ideal management strategy for correction of ureteropelvic junction (UPJ) obstruction remains undefined. Open pyeloplasty for correction of UPJ obstruction was first described by Anderson and Hynes over a century ago and remains the gold standard against which we must compare all alternative therapies.
Recurrent UTIs caused by original E coli strain
March 1st 2005Washington—A majority of recurrent urinary tract infections in women are caused by Escherichia coli bacterial persistence or reinfection with the originally infecting E coli strain, according to findings from a Danish study presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy.
Some VUR patients can safely stop antibiotics
March 1st 2005San Francisco—Selected children with persistent vesicoureteral reflux can safely discontinue prophylactic antibiotics without a significant risk of upper tract infections or new renal scarring, according to results of a retrospective Canadian study.
Surveys reveal shift in treatment of UPJ obstruction
March 1st 2005Mumbai, India—Since the introduction of percutaneous endopyelotomy in the mid 1980s, the treatment of adult ureteropelvic junction obstruction has undergone a tremendous change. In addition, with the increasing use of laparoscopy to treat urologic diseases, various endoscopic and laparoscopic techniques now offer success rates comparable to those of the traditional open surgery while minimizing patient morbidity.
Two techniques help improve results of PCNL
March 1st 2005Mumbai, India—Two newer techniques offer potential to improve the experience for patients undergoing percutaneous nephrolithotomy, according to separate presentations made at the World Congress on Endourology. One study focused on using a plastic model for visualization purposes before operating on complex renal stones, and the other examined the effectiveness of a hemostatic gelatin matrix to seal the percutaneous nephrostomy tract.
New contralateral VUR post-implant is not uncommon
March 1st 2005San Francisco—New contralateral vesicoureteral reflux occurs more often than previously thought following endoscopic treatment of unilateral VUR and may warrant further treatment, according to a report presented at the American Academy of Pediatrics Section on Urology meeting here.
Endoscopic therapy shows high success rate for VUR
March 1st 2005San Francisco—Endoscopic therapy for vesicoureteral reflux has a high success rate and a low risk of obstruction compared with open surgery, but multiple treatments may be necessary to achieve a cure, results of a meta-analysis of published studies indicate.
Data find wide variation in BPH treatment patterns
March 1st 2005Mumbai, India—Rates of surgical and medical therapy for BPH at the county and state levels show significant systematic variation, according to Duke University researchers, who reported their findings during a presentation at the World Congress on Endourology here.
Healthy weight reduces risk of kidney stones
March 1st 2005Boston—Findings from analyses of data collected in three large, prospectively followed cohorts show that obesity and weight gain increase the risk of kidney stone formation in younger and older adult men and women, according to recently published research from Brigham and Women's Hospital, Harvard Medical School, Boston.
PSA is inversely associated with body mass index
March 1st 2005San Antonio—A study showing that PSA levels appear to have an inverse relationship with body mass index does no harm to the value of the screening test, says Ian M. Thompson, Jr, MD, one of the study's principal authors. Rather, it provides further evidence that PSA cutoffs alone may not best estimate a man's risk of prostate cancer.
