(HealthDay News) — In the United States, the use of partial nephrectomy procedures to manage renal masses in patients with renal cell carcinoma (RCC) increased significantly from 2002 to 2008, according to research published in the March issue of The Journal of Urology.

Sanjay G. Patel, M.D., of the Vanderbilt University Medical Center in Nashville, Tenn., and colleagues utilized the National Inpatient Sample database to identify 46,396 inpatient stays for a total weighted sample size of over 226,000 patients who had undergone radical or partial nephrectomy for a renal mass between 2002 and 2008. National trends of partial nephrectomy were examined, and nonclinical predictors of the procedure were evaluated.

The investigators found that, over the study period, use of partial nephrectomy in the United States increased significantly, from 15.3 to 24.7 percent. On multivariate analysis, independent predictors of partial nephrectomy use included hospital attributes (urban teaching status, nephrectomy volume, geographic region) and patient socioeconomic status (higher income ZIP code and private/health maintenance organization payer).

“Appropriate use of nephron sparing surgery for RCC can be viewed as a quality of care indicator. Since 2002, the national use of partial nephrectomy for the management of renal masses has increased at a higher rate than the general incidence of RCC,” the authors write.

Several authors disclosed financial ties to pharmaceutical companies.
