SAN DIEGO—Serum autoantibody profiling may provide a novel non-invasive diagnostic tool for bladder cancer, according to researchers at the Spanish National Cancer Research Center in Madrid.

WASHINGTON, D.C.—Targeted renal therapy (TRT) involving intrarenal administration of fenoldopam is safe and feasible in patients undergoing angiographic procedures, even in patients at elevated risk of suffering from contrast-induced nephropathy (CIN).

WASHINGTON, D.C.—Tunneled dialysis catheters may be implanted without a sheath to limit the size of the venotomy and thus the potential for bleeding following catheter placement, according to a pilot study.

WASHINGTON, D.C.—Restenting and angioplasty are both highly effective for treating renal artery in-stent stenosis, according to findings presented here at the Society of Interventional Radiology's 33rd Annual Scientific Meeting. Findings also suggest that in-stent restenosis may be associated with stent fractures.

WASHINGTON, D.C.—A "halo sign" is a common delayed finding following radiofrequency ablation (RFA) of kidney tumors, according to researchers at the University of Toronto.

WASHINGTON, D.C.—Patients with an endovascular aneurysm repair (EVAR) should be considered a high-risk group for renal artery interventions and receive closer post-procedure surveillance.

WASHINGTON, D.C.—The fluency expanded polytetrafluoroethylene (ePTFE)-coated stent is effective for treating angioplasty-related extravasation in arteriovenous (AV) grafts and fistulae. Data showed a high rate of technical success with this approach, but primary patency rates were low.

WASHINGTON, D.C.—Catheter-based blood flow measured at the end of hemodialysis access revascularization procedures may predict graft survival, new data suggest.

SAN DIEGO—Genetic analyses suggest that prostate cancer in African-American men is distinctly different as compared with European-American men, according to researchers at the National Cancer Institute (NCI) in Bethesda, Md.

ORLANDO—Researchers have succeeded in regenerating an entire urinary bladder in large mammals, according to new study findings presented here at the American Urological Association annual meeting.
