Director Dou's judgment is very accurate.

In the operating room, as soon as the ureteroscope was placed in place, Yamashita Oda reminded: "The energy of the holmium laser is too high. Change it to a high-frequency and low-energy mode so that the stone can be broken better."

Su Jie thought for a moment, nodded calmly, and agreed with Yamashita Oda's opinion.

The CEO of the Department of Urology on the side suddenly had a solemn expression and his brows were furrowed.

This guy!

Doesn’t it mean that Yamashita Oda can’t perform several stone operations a year, and most of them will choose percutaneous nephroscopic surgery? Why is he so familiar with the energy mode selection of powdered lithotripsy?

Only then did the CEO of the Department of Urology realize that he had been careless. Yamashita Oda might not be as familiar with flexible ureteroscopy surgery as he thought. In fact, the opposite might be true!

"Dr. Su, if there is any problem during the operation, Director Dou is in the observation room and can take over at any time." The CEO of the Department of Urology reminded tactfully.

Su Jie raised his head and glanced at Director Dou in the observation room. He just nodded slightly without saying much, and then withdrew his gaze.

Did Dr. Su understand what I meant? The boss of the Department of Urology was not sure and felt extremely uneasy.

The situation has changed. Yamashita Oda is obviously well prepared. As long as Dr. Su starts the operation, I am afraid that Yamashita Oda will soon see through the technique of powdered gravel...

However, Su Jie seemed not to be aware of the current situation at all. He just stared at the ureteroscope that had penetrated deep into the renal pelvis with clear and focused eyes.

The gravel begins.

Su Jie stared intently at the screen of the ureteroscope. Yellow stones accumulated in the kidney, almost filling the entire renal pelvis. They looked like a pair of high-spirited antlers, extremely fierce.

After practicing for 48 hours continuously in the virtual operating room, and with the guidance from the head of the Department of Urology, Su Jie was now confident in the treatment of staghorn stones.

But when he saw the stones in the patient's kidneys, he couldn't help but let out a slight sigh and narrowed his eyes slightly.

"Weird..." Su Jie muttered softly.

However, this confusion did not seem to be able to stop Su Jie's operation. He was seen operating the ureteroscope's holmium laser system with both hands. One hand controlled the lens, and the other hand guided the holmium laser probe to slowly approach the stone.

Yamashita Oda watched Su Jie's every move intently, and also paid attention to the CEO of the Department of Urology. What confused him was that the CEO of the Department of Urology seemed to have no intention of communicating and providing guidance. Although his expression was solemn, he seemed to be determined.

Let Su Jie enjoy the surgery.

But even so, Yamashita Oda felt that it didn't matter. Novices like Su Jie were not good at hiding real skills. As long as you carefully observed his surgical operations, you would definitely understand the key techniques of staghorn stone surgery.

At Yamashita Oda's reminder, the holmium laser energy was adjusted to the best high-frequency and low-energy mode for powdered lithotripsy. Su Jie guided the holmium laser probe to slowly approach a floating stone, and then turned on the energy to perform lithotripsy.

For the first powdered gravel technology, Su Jie chose the peripheral chipping method, which evenly polishes the surface of the stone and crushes it from the outside to the inside.

The CEO of the Department of Urology frowned and occasionally glanced at Yamashita Oda, who was closely watching Su Jie's operation. His inner anxiety was indescribable.

Su Jie's surgery was performed without any problems and was very standard, almost a model surgery.

But the more this happens, the more painful it becomes for the boss of the department of urology.

How is this different from those women in romantic places who lift up their skirts and let you pick them? The surgery was so smooth and standard that Yamashita Oda almost laughed!

Su Jie was still too young, and the surgery was done so neatly that he didn't even know how to use a smoke bomb!

The boss of the Department of Urology couldn't help but look up at Director Dou in the observation room, thinking about how to find a reason to change the owner of this surgery.

But at this moment, the CEO of the Department of Urology suddenly heard a strange "hmm" sound from Oda Yamashita.

"What's wrong? Something went wrong with the operation?" the boss of the Department of Urology asked in surprise.

"Are you happy that something went wrong?" Yamashita Oda asked.

"How, how is it possible? I'm worried." The boss of the Department of Urology quickly said with a serious face.

Yamashita Oda said: "Why do you need to change to gravel technology midway?"

"Change to gravel technology?"

The CEO of the Department of Urology quickly looked at the screen of the ureteroscope and discovered that Su Jie, who had just used the peripheral chipping method, now started to use the middle drilling method, and the target was still the same stone.

"smoke bomb?"

The boss of the Department of Urology was also stunned.

Why are two completely different techniques for crushing the same stone used? This is not a requirement for powdering. Did Su Jie suddenly become enlightened? Did he know how to use smoke bombs to confuse Yamashita Oda?

But soon, the boss of the Department of Urology discovered that things were not that simple...

Observation room on the second floor.

Director Dou also noticed Su Jie's change in lithotripsy technique. He couldn't help but lean forward slightly and hold on to the handrail in front of the glass window.

"What is Dr. Su doing? Why do he use completely different lithotripsy techniques for the same stone? For a type of stone, use the most suitable lithotripsy technique for it, so that the powdering effect can be achieved."

A well-known middle-aged urological surgeon said solemnly: "With two completely different lithotripsy techniques, there will definitely be some stones that are not well powdered. Once stones of 3~4mm appear, the holmium laser will be ineffective against them. A large number of stones will not be pulverized well."

The particles collect in the kidneys and the patient soon develops a second round of stones."

Someone speculated: "Dr. Su is trying to confuse Yamashita Oda. Is it inappropriate to use this method?"

Director Dou shook his head and said: "Look carefully, the powdering effect has always been very good. Such fine fragments of residual stone are not huge compared with a 200μm diameter optical fiber."

Everyone looked at the scene where Su Jie was crushing stones. Indeed, the yellow powder was raised and quickly integrated into the liquid, with no large particles escaping.

"Why do completely different lithotripsy techniques produce the same effect on the same stone?"

Everyone was puzzled. According to their understanding of powdered lithotripsy technology, only by using corresponding lithotripsy technology for different stones can such a perfect effect be achieved. But why could Su Jie achieve this?

Is it possible that no matter what the stone crushing technology is, Su Jie can perfectly crush the stone in his hands?

This unscientific!

Director Dou pondered for a long time, watching Su Jie successfully crush a stone, and then murmured: Three stone crushing techniques... three techniques were actually used for one stone, and they were all completely different techniques.

For hard stones, some are brittle, while others have a loose structure...

"Is this a mixed stone?"

Director Dou suddenly thought of something and raised his voice slightly:

"A mixed stone contains two or more components in one stone? So different stone crushing techniques are used, but the perfect stone crushing effect is achieved?"
Chapter completed!
