Renal Masses

Preventing Needless Nephrectomies Possible

Large Renal Masses Grow Faster than Small Ones

Jody A. Charnow May 16, 2011

WASHINGTON, D.C.—Renal masses greater than 4 cm in diameter tend to grow faster than smaller masses, a researcher reported at the American Urological Association 2011 annual meeting.

MR-Guided Laser Ablation Safe and Effective for Small Renal Masses

John Schieszer April 18, 2011

MR-guided laser ablation appears to be safe and effective for treating small renal masses.

NSS Suitable for Larger Tumors, Regardless of Age

Delicia Honen Yard March 29, 2011

Nephron-sparing surgery (NSS), the gold-standard treatment for renal tumors 4 cm or less in diameter, appears to benefit long-term kidney function in cases involving larger tumors as well—even in elderly patients, according to findings published in BJU International (2011;107:554-561).

Desmopressin Curbs Kidney Biopsy Bleeding

Jody A. Charnow March 17, 2011

Desmopressin administered prior to percutaneous kidney biopsy decreases the risk of bleeding and hematoma size from the procedure, according to researchers.

Cryoablation Suitable for Larger Renal Masses

Jody A. Charnow August 10, 2010

Percutaneous cryoablation of larger renal masses can be performed with high technical success and low complication rates, according to researchers.

Warm Ischemia Worsens Partial Nephrectomy Outcomes, Study Finds

Jody A. Charnow July 20, 2010

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.

Small Renal Masses Are Overtreated

Jody A. Charnow April 26, 2010

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.

Hospitalization After Renal Ablation Unnecessary

John Schieszer April 02, 2010

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.

CT Accurate For Measuring Renal Tumors

Jody A. Charnow April 01, 2010

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

Large Renal Tumors Grow More Quickly

Jody A. Charnow March 30, 2010

Patients with large renal tumors require immediate treatment, according to German researchers.

Excellent Short-Term Outcomes Reported for Robot-Assisted Partial Nephrectomy

Jody A. Charnow March 02, 2010

Robot-assisted partial nephrectomy (RAPN) is a safe and effective approach for nephron-sparing surgery (NSS) that is capable of providing patients with excellent short-term oncologic outcomes, according to the largest RAPN experience described to date.

Partial Nephrectomy for Larger Renal Masses

Nicholas Muruve, MD October 08, 2009

Partial nephrectomy has been the procedure of choice for patients with poor renal function, tumors in solitary kidneys or bilateral renal tumors.

Less Bed Rest Is Safe After Renal Biopsy

Jody A. Charnow September 18, 2009

Shorter periods of strict bed rest after a renal biopsy can safely decrease patient discomfort, according to a Japanese study published in Clinical and Experimental Nephrology (2009; published online ahead of print).

Central Renal Masses More Likely to Be RCC

Jody A. Charnow June 30, 2009

TORONTO—Centrally located renal masses are five times as likely as peripherally located masses to be renal cell carcinoma (RCC), according to researchers.

Delaying LPN Okay for Small Renal Tumors

Jody A. Charnow May 12, 2009

Delaying laparoscopic partial nephrectomy (LPN) for patients with small renal masses has no significant effect on oncologic and perioperative outcomes.

Observing Renal Masses May Suffice

Jody A. Charnow February 13, 2009

Observation may be an appropriate management strategy for renal masses in older patients and those with comorbidities, according to investigators.

Robotic Single-Port Surgery Proves Successful

Jihad Kaouk, MD February 09, 2009

Cryoablation for Unresectable Renal Tumors

John Schieszer July 21, 2008

WASHINGTON, D.C.—Cryoablation is an appropriate option for patients with unresectable renal masses, but long-term follow-up studies are needed before this modality can be expanded to treatment of all potential surgical candidates, researchers say.
