Surgery insight: advances in techniques for open partial nephrectomy.

With the widespread use of abdominal imaging, there has been a substantial increase in the detection of incidental, small renal masses. This change has resulted in a downward trend in the size and stage of tumors being detected, and a corresponding increase in the number of renal cortical tumors amenable to partial nephrectomy. Based solely on a size criterion of 7 cm or less (pT1), nearly 70% of all patients with newly diagnosed kidney tumors are eligible for partial nephrectomy. Here, we briefly review the current rationale for partial nephrectomy and provide insight into advances in the technique of open partial nephrectomy. In addition to describing in detail the surgical techniques used at our institution, we also report the outcomes of our series of open partial nephrectomies performed via a mini-flank incision above the 11th rib. We believe that this approach offers a safe, practical and easily adoptable alternative to traditional open partial nephrectomy and laparoscopic partial nephrectomy.
