After the “one-stop” composite surgery model was adopted by the surgical team led by Professor Jiang Jun of the Department of Urology on February 2, the team again cooperated with the Department of Radiology on February 16 to complete the surgical treatment of renal malformation tumor using a combination of lumpectomy and interventional techniques. This “one-stop” combination of minimally invasive lumpectomy and minimally invasive interventional surgery mode not only reduces pain for patients, but also reduces surgical risks and post-surgical complications. It opens a new way for the application of “one-stop” composite surgery platform in our hospital. According to Prof. Jiang Jun, renal malformation tumor is a benign tumor composed of mature or immature fat, malformed blood vessels and smooth muscle, which has the characteristics of outward growth and rich blood supply. The aim of surgical treatment is to remove the tumor and protect the kidney function. In traditional open and laparoscopic resection of malignant tumor, the main blood vessels of kidney must be blocked during surgery, which requires the surgeon to complete the tumor removal and kidney suture wound quickly in a short time. Laparoscopic one-stop minimally invasive surgery using super-selective renal vascular embolization technique can complete tumor resection without blocking renal blood flow, which greatly reduces the damage to the kidney and intraoperative bleeding, and significantly improves safety compared with traditional surgery. The patient’s malformation tumor was located in the lower pole of the right kidney, measuring 8×7 cm. Before laparoscopic surgery, the right renal artery was angiographed to clarify the blood supply to the tumor, and the artery supplying the tumor was super-selected for embolization, after which the balloon was placed in the main trunk of the right renal artery for backup. The tumor was separated and resected under laparoscopy. As the operation went smoothly, no right renal artery balloon block was performed to ensure that the tumor was removed without ischemia and affecting the kidney function, and only 50 ml of blood was bled during the operation.
