Warm ischemia during partial nephrectomy (PN) on a solitary kidney is associated with an increased risk of acute renal failure (ARF) and CKD, according to researchers.

Cook Medical, of Bloomington, Ind., has introduced BIGopsy Backloading Biopsy Forceps, a device that has a 4 mm3 biopsy cup to obtain large renal or ureteral tissue specimens for cancer diagnosis.

Two proteins excreted in the urine appear to be sensitive and specific biomarkers of renal cancers of proximal tubule origin, possibly allowing for early screening for the disease.

Chronic infection with hepatitis C virus (HCV) increases a person's risk for renal cell carcinoma (RCC), a study found.

TAMPA, Fla.—Cryoablation guided by magnetic resonance (MR) imaging is safe and effective for treating solid renal tumors, even those up to 7 cm in diameter, according to new data presented here at the Society of Interventional Radiology annual meeting. The technique could be an alternative to partial or total surgical resection.

SAN FRANCISCO—Active surveillance of small renal masses (SRMs) may be an appropriate approach for many patients, especially older individuals and those with comorbidities that would complicate treatment or reduce life expectancy, according to Michael Jewett, MD, of Princess Margaret Hospital and the University of Toronto.

Kidney cancer is likely to develop in men whose jobs expose them to high levels of sunlight than in men whose work does not expose them to the sun, according to a study published in Cancer (published online ahead of print).

TAMPA, Fla.—Ablation of renal masses can be performed routinely as outpatient procedures and usually do not require hospital admission for post-procedure observation, researchers reported here at the Society of Interventional Radiology annual meeting.

Computed tomography (CT) images generally provide an accurate assessment of the size of renal tumors, researchers have concluded.

Shrinking percentages of patients have hematuria and elevated erythrocyte sedimentation rates.
