What is HIFU technology?
The HIFU technology is also known as HIFU.
High intensity focused ultrasound (HIFU) technology is also known as HIFU technology, similar to a magnifying glass that produces high temperature at the focus of sunlight. The focal point is amplified tens of thousands of times, which instantly generates a high temperature of 60~100℃, so that the focal point temperature can achieve the effect of killing the tumor (coagulating protein and killing cells) in an instant, thus achieving the purpose of destroying the diseased tissue or tumor cells. The tumor tissue killed by Hefu loses its vitality (ability to proliferate, infiltrate and metastasize) and is gradually dissolved and absorbed by the body through natural metabolism.
Currently, in the treatment of tumors, because HEFI technology can treat deep tumors in the body without incision and trauma, and cause minimal damage to normal body tissues outside the tumor, it is also known as HEFI non-invasive surgery, and some people call it HEFI knife.
Which kidney cancer patients are suitable for HIFU treatment?
Similar to radiofrequency ablation and cryoablation, HIFU is primarily used in patients who are inoperable. These include:
- Patients with early-stage tumors who cannot tolerate surgery, or who cannot accept the complications associated with surgery.
- Patients with locally progressive tumors who are unable to undergo radical surgical treatment.
- Patients with advanced tumors with distant metastases.
- Patients with advanced tumors that have distant metastases.
- Patients with local recurrence after radical treatment.
- Patients with locally recurrent tumors after radical treatment.
What is the efficacy?
The results of the current study show that the results of the thermal “resection” of the body tissue by HIFU are very positive, and the specimens that were surgically resected after HIFU showed very well-defined areas of coagulative necrosis in the target area.
What are the complications?
HIFU therapy is a very important tool for the treatment of HIFU.
Complications of HIFU treatment are still very low, and common ones include skin injury, nerve injury, and intestinal injury. Some of these complications can be avoided or mitigated through a series of preventive measures. Even when complications do occur, the vast majority are recoverable. Patients need to communicate with their physicians in a timely manner when they experience some symptoms of discomfort.
