    Enucleation for RCC yields multiple benefits

    In patients undergoing robotic partial nephrectomy for renal cell carcinoma, renal tumor enucleation maximally preserves normal renal parenchyma and provides better surgical precision compared to the standard technique, and it appears to do so without compromising oncologic outcomes, reported Gopal N. Gupta, MD, at the AUA annual meeting in San Diego.

    Gopal N. Gupta, MDDr. Gupta“Partial nephrectomy has gained favor for the surgical treatment of renal masses less than 7 cm because compared with radical nephrectomy, it maximally preserves normal renal parenchyma, thereby optimizing renal function and potentially overall survival,” said Dr. Gupta, of Loyola University Medical Center, Maywood, IL.

    “Now, using a validated construct, we have demonstrated for the first time that when using a minimally invasive technique that further benefits patients, tumor enucleation is maximally parenchymal preserving and more precise than standard partial nephrectomy. In addition, our experience indicates tumor enucleation is safe from an oncologic perspective in the short term.”

    A retrospective study by Dr. Gupta and co-authors included 57 patients who underwent tumor enucleation and 53 patients who had standard partial nephrectomy. All of the patients had undergone computed tomography or magnetic resonance imaging preoperatively within 2 months before surgery and 4 to 12 months after surgery. They also had estimated glomerular filtration rate data from the same pre- and postoperative time frames.
