Yichun Zheng, Doctor

Partial nephrectomy(PN) and tumor enucleation(TE) are the two main methods of Nephron-sparing surgery for early renal cell carcinoma. Because of its blunt separation, TE is often considered to be difficult to completely remove tumor tissue. In addition, compared with PN, TE is more difficult and has higher professional requirements for surgeons. Therefore most surgeons use PN. But Many studies have shown that TE has advantages over PN such as less trauma, faster recovery, and better protection of renal function without increasing the risk of tumor recurrence.

The main renal artery should be clamped during PN to achieve a relatively bloodless operation environment to ensure the safety of tumor resection. However, too long warm ischemia time will inevitably affect the function of normal renal tissue. Studies have shown that shortening the time of renal ischemia is closely related to the recovery of renal function after the operation. So reducing the time of warm ischemia until zero ischemia has become the pursuit of surgeons. Based on renal cell carcinoma resection combined with zero ischemia technique, renal parenchyma, and renal function can be protected to the maximum extent on the premise of ensuring tumor safety.

The purpose of this study is to explore the safety and efficacy of zero-ischemia TE by analyzing the data of early renal cell carcinoma patients who had undergone PN and zero-ischemia TE before.

According to the inclusion and exclusion criteria，collecting the data of participants who have undergone partial nephrectomy or renal tumor enucleation.

The investigators will compare the difference between TE and PN, clamped-enucleation and unclamped-enucleation, suture and sutureless zero-ischemia enucleation by the data the investigators collected.

After analysing the data, the investigators will discuss the safety and efficay of the sutureless zero-ischemia tumor enucleation. The patient who would be benefited from this operation and the patient who would be suggested to undergo this operation will also be discussed.
