In the field of urology, ureteroscopy has become an important instrument for minimally invasive treatment of upper urinary tract stones. The flexible ureteroscope can directly explore the location, size, shape and surrounding mucosal condition of stones through the natural cavity of the human body (urethra-bladder-ureter). Compared with traditional percutaneous nephrolithotomy(pcnl), FURS significantly reduces the risk of bleeding and postoperative pain, shortens the recovery time, and has become the preferred treatment option for many patients with kidney stones.
In FURS, clear and stable endoscopic imaging is the key to successful surgery. Blurred and noisy images will make it more difficult for doctors to identify stones and distinguish between tiny blood vessels and mucosal structures, which will not only prolong the operation time, but also pose the risk of accidental injury to tissues and residual stones.
In this issue, we will use the actual intraoperative images of kidney stone holmium laser lithotripsy performed by “Hikimaging ureteroscopy solution”to intuitively experience the surgical process and the technological innovation brought about by high-definition imaging.
- Ureteroscopy to explore the renal pelvis and accurately locate stones
The ureteroscope needs to be fully lubricated before insertion to reduce damage. Under the guidance of the guide wire, the target position is successfully reached through the urethra, bladder, and ureter. Doctors can flexibly control the endoscope through foot pedals or handles to systematically explore and locate the stones.
2. Ureteroscopy to explore the renal pelvis and accurately locate stones
After confirming the target stone, the holmium laser fiber is inserted through the working channel of the soft mirror. The laser spot is precisely focused on the surface of the stone, and the “fragmentation” strategy is used to break the stone into sufficiently small particles.
3. Postoperative reexamination to ensure that there are no “stones”
After lithotripsy is completed, the renal pelvis and target calyces are examined again with a ureteroscope to ensure that there are no residues and to check the degree of tissue damage.
Hikimaging ureteroscope solution, through the unique super-resolution technology, effectively improves the clarity of electronic mirror imaging. It can be used in combination with a variety of host options such as portable host and dual-mirror host, and can be flexibly used in consulting rooms and operating rooms. It provides a powerful tool for urologists and allows minimally invasive surgery to move further into a new era of “seeing clearly and doing accurately”.
