Urinary tract problems｜Be careful with painless hematuria, kidney cancer attacks, minimally invasive surgery robotic arm preserves​​​​kidney function and quality of life – Hong Kong Economic Times – TOPick – Health – Medical Figures

Many middle-aged and elderly men suffer from urinary problems. If the tumor is detected in time and is at an early stage, there is an opportunity to use a minimally invasive surgery with a robotic arm to remove part of the kidney, reducing the risk of kidney failure that may occur. be caused by complete kidney removal, allowing the patient to recover faster while maintaining quality of life.

Dr. Tan Baochu, an expert in urology, explained that if the patient does not feel pain when urinating and urinating, and there is blood during the process, it is an obvious sign of cancer kidney, which often occurs in the middle and late stages. of cancer. Other symptoms include low back pain, or shortness of breath or bone pain caused by cancer cells metastasizing to the lungs or bones. Although smoking and obesity are high risk groups, when symptoms appear later, is there a chance that the cancer will be caught early?

Physical examination ultrasound can catch cancer at an early stage

“In recent years, more than half of kidney cancer cases were detected through physical ultrasound examinations of patients, and most of them were in the early stages.” cancer, and the majority of kidney cancers found through physical examinations are In the first and second stages, the tumors are smaller and can be removed through surgery.

Traditionally, as soon as kidney cancer is present, open surgery is performed to remove the entire kidney to prevent cancer cells from coming back. However, the surgical wound is large and the remaining healthy kidney tissue is lost at the same time Studies have shown that patients with total kidney removal are 20 to 30% more likely to have kidney dialysis at the time of the arrival of the patients who have only part of. the kidney has been removed, especially those with diabetes or kidney disease. In addition, some studies have found that if the cancer is stage 1A and the diameter of the tumor is less than 4 cm, even if only part of the kidney and the tumor are removed, the chance of cancer recurrence and kidney failure will be lower with dialysis. However, the risk of a partial kidney resection is slightly higher than that of a complete resection. Secondary bleeding and urine leakage may occur after the operation, but it can be monitored and treated.

Remove part of the kidney to reduce the risk of kidney failure

Therefore, with the advancement of medicine, if the size, complexity and location of the tumor, such as being located under the kidney, or protruding at the front under the kidney, etc., laparoscopic surgery will be less invasive or A robotic arm can also be considered for cases that meet the conditions for partial nephrectomy.

Dr Tan said robotic arm surgery, which has become popular in recent years, is suitable for removing stage 1A kidney cancer tumors. The robotic arm is more precise and flexible than the accurate and precise laparoscope. Therefore, robotic surgery is faster than laparoscopy, reduces operating time, and also meets the requirements of operations that need to repair more kidney tissue.

The robotic arm accurately positions the needle and sews quickly

In addition, the 3D field of view provided by the robotic arm can be increased ten times to provide a three-dimensional effect, making it easier for doctors to operate the knife. For patients, the biggest benefits of robotic arm surgery are thin wounds and quick recovery. Taking kidney cancer resection for example, only six to seven eight mm incisions are made in the patient’s abdomen. The patient can be discharged from the hospital about four days after the surgery.

Mr. Deng (pseudonym), 50 years old, underwent an ultrasound during a physical examination and found a shadow under his left kidney, which was suspected to be kidney cancer. The tumor and part of the kidney were removed via a robotic arm.

Dr Tan said that for the first stage of kidney cancer, if the doctor has experience, the expected five-year survival rate for both traditional open surgery and robotic arm surgery to remove kidney cancer more than 80%.

Dr. Tan reminds us that there are many treatment options for kidney cancer, each with different effects and side effects. If patients have any questions, they should consult their treating doctor.
