Renal tumor is one of the common tumors in urology. With the progress and popularity of lumpectomy technology, our urology department has long applied laparoscopic surgery technology in the surgical treatment of renal tumors, and it has achieved very good clinical treatment effect and has been well received by the patients. The incision of traditional open surgery is more than 30 cm long, and postoperative pain and limited mobility of patients in the lower back and abdomen can seriously affect their daily life and work. Through the lumpectomy technique, the tumor of the kidney can be completely surgically removed with only 3 to 4 small 1-2 cm holes in the waist. Then, depending on the size of the specimen, the specimen can simply be removed through a suitable small hole. The lumpectomy is much less damaging to the patient’s body and greatly reduces many adverse effects such as postoperative lumbar and abdominal pain and limited mobility. Moreover, in lumpectomy, the laparoscope can magnify about 8 times, which can make the surgical anatomy more delicate, reduce bleeding, enable the surgeon to identify the diseased tissues more precisely, remove them more thoroughly, make the surgery safer, and make the patient recover faster after the surgery, and basically have little effect on the patient’s daily life. With the development and progress of science and technology, the development of medicine is also changing day by day. It is our goal to be able to relieve patients’ suffering through advanced medical technology and, at the same time, to minimize the damage to patients. May all patients recover soon and all families be happy and harmonious!
