Partial nephrectomy: novel closure technique using bovine pericardium.

Partial nephrectomy (PN) has gained popularity over the past two decades as an alternative to radical nephrectomy (RN) in patients with small renal masses. Morbidity and mortality from PN have been shown to be lower than from RN, while oncologic outcomes have been shown to be equivalent for tumors < 7 cm. PN has become increasingly popular in academic centers, but the general urologic community continues to lag behind. The reason for this is not known, but may be related to the relatively high complication rate, including delayed complications associated with inadequate closure. Here we describe a novel PN closure technique that provides additional strength and hemostasis by incorporating bovine pericardium.
