Man suffers from huge complex kidney tumour Guangdong hospital successfully cuts tumor and preserves kidney

Sun Yat-sen University affiliated with the first hospital said on the 14th, the hospital's urology professor Luo Junhang team used Da Vinci robot-assisted surgery technology and improved renal vascular blocking technology, for a patient suffering from a huge complex right kidney cancer to completely remove the tumor and retain the right kidney, reducing the patient's risk of hypertension, uremia after surgerypatient is a 56-year-old male from The Tide, Guangdong Province, the imaging examination indicated that his right kidney tumor is located in the middle of the kidney, the maximum diameter of more than 7 cm, most of the tumor tissue is located in the essence of the kidney, and close to the renal and sinus blood vesselsLuo Junhang explained that a normal kidney is 10 to 12 cm tall and 5 to 6 cm wideThe patient's kidneys grow a huge 7 cm malignant tumor, "the kidney tumor is less than 4 cm, the kidney is routinely to protect the kidney, if between 4 to 7 cm, can be preserved kidney or not, once it is more than 7 cm of huge tumor is usually not kidney retention."because the patient's left urinary tract has a history of stones and water accumulation, he hopes that the health care team will try to preserve his right kidney function, reduce the risk of uremia, cardiovascular accidents and other long-term postoperative" but it makes sense that the conventional is not for such a large tumor, because once the tumor is removed cleanly or the envelope ruptures, there are residual cancer cells in the kidneys that increase the risk of recurrence and metastasisLuo Junhang said, in addition, such a huge tumor in the process of removal and stitching will take more time, kidney ischemia time if too long, "kidney damage, kidney preservation also has no meaning."in view of the patient's situation, Professor Luo Junhang and Associate Professor Chen Xu of the hospital, etcbased on imaging information for kidney and vascular reconstruction, according to the characteristics of the patient's tumor and vascular distribution and the advantages of using Da Vinci robot assisted technology for urinary tract reconstruction and repair, the development of branch renal artery step-blocking, Da Vinci robot auxiliary renal partial removal surgery programlarge complex kidney cancer of the hysteresis of the scope of the surgical removal, deep surface, in order to prevent postoperative bleeding and urine leakage, doctors need to fine stitch the wound surfaceLuo Junhang said that the traditional artificial stitching and laparoscopic device stitching only 4 degrees of freedom, Da Vinci robot "wrist" flexibility, can have 7 degrees of freedom to stitch, which can reduce the occurrence of postoperative complications, but also shorten the ischemia time of the kidneys, Luo Junhang's team adopted a strategy of precisely blocking and sequentially opening multiple branched renal arteries to ensure the complete removal of the tumor while shortening renal ischemia and protecting kidney functionAfter surgery, the patient's renal function review results are basically the same as before surgery, the patient has recovered and discharged from the hospitalLuo Junhang introduced, the traditional renal surgery has renal artery trunk blocking and selective renal artery branch blocking two renal artery blocking methodsThis improved branch of renal artery step-by-step blocking to take into account the advantages of two traditional techniques and make up for their shortcomings, the application in the huge complex kidney cancer of kidney surgery has two advantages" advantage is mainly reflected in shortening the time of renal ischemia and the surgical field of vision clear blood seepage Luo Junhang said that the traditional selective tumor branch arterial blocking kidney surgery, although it can be a good protection of kidney function, but applied to the huge complex kidney cancer of kidney surgery, there will be a lot of bruising, lack of vision and other problems, increase the risk of tumor residue and planting caused by cutting tumor envelope, improved surgery will be huge complex renal tumor retention surgery in about 20 minutes, better protection of kidney function, and beneficial to the complete removal of huge complex tumor complications by Bai Jiaxuan Source:
