The boss of the Department of Urology still had a lot of things to do, so he left early.

Su Jie stayed in the simulated operating room of the Department of Urology to continue practicing.

The powdering technique sounds very simple, but when it was actually used, Su Jie discovered why this technology has become a cutting-edge technology in the industry.

This technology requires too much selection of surgeons...

Technologies that can be called cutting-edge are inevitably only in the hands of a small group of doctors.

The reason for this situation is often that the operation is too difficult, and most doctors can only stay away from it.

"If you want to achieve powdering, mastering the flexible ureteroscope holmium laser lithotripsy is just the basics, but even this basic requirement can probably wipe out half of the urological surgeons."

"But it is not enough to be proficient in lithotripsy. You must also be familiar with various lithotripsy techniques."

"But this is still not enough... What is really difficult is how to deal with different stones, choose the correct stone fragmentation method, and complete the feat of reducing the remaining stone fragments to less than 2mm in one go!"

Su Jie tried it many times and soon discovered the greatest difficulty of this technique.

When he chooses inappropriate lithotripsy techniques and crushes the stones into less than 4mm, it becomes difficult for the stones to remain under his control.

Tiny particles float in the ureter, just like a drop in the ocean. Even if the energy of the holmium laser is adjusted to the minimum, it will not be able to have an effect on such an insignificant existence. As soon as the energy wave approaches, the tiny particles will slyly escape, and soon they will

It disappeared under the ureteroscope and is hard to find again.

Simply put, there is only one chance for stone fragmentation. Once the size of the stone is reduced to about 4mm, any stone fragmentation technique will be ineffective.

However, a large number of 3~4mm residual stone fragments cannot be smoothly excreted from the body and accumulate in the ureter, which will only become an opportunity for the recurrence of stones next time.

"The key lies in the composition of the stones. Different compositions, different hardnesses, and different densities also have very different stone crushing techniques."

Su Jie was thinking and simulating experiments.

The difference between geniuses and ordinary people may be here.

If it were another doctor who knew the essentials of powdering technology, he would have practiced it thousands of times. Even if he couldn't grasp the essentials, he firmly believed that practice makes perfect.

But Su Jie didn't. After several experiments, he quickly realized where the real difficulty of this technology was, and made small improvements to this technology based on his own advantages.

That's right, improve it, improve it into [Sujie version·Powdered antler-shaped stones].

The stones in the simulated ureter had been wasted, and Su Jie was too lazy to go to the Department of Urology to get new stones.

after all.

Problems that can be solved using points are not problems.

With his eyes closed, the world was wrapped in black, and Su Jie entered the virtual operating room.

boom.

The shadowless light came on, followed by the cold mechanical sound of the system.

"Whether [Flexible Ureteroscope Holmium Laser Lithotripsy Practice System] is activated."

"Activate." Su Jie replied.

On the operating table, a complete set of flexible ureteroscope and holmium laser lithotripsy equipment immediately appeared.

Moreover, compared with the simulated operating room of Department of Urology, the simulated person lying on the operating table is more realistic, giving people a sense of solemnity like a real surgeon.

"The system simulates staghorn stones, and the stone component types are randomly generated."

"Simulated." The cold system sound sounded.

From Su Jie's point of view, there was no change in the simulator on the operating table, but as he began to operate the ureteroscope and crush the stones, the evil intentions of the system gradually became apparent.

The stones floating in the ureter all look like yellow, irregular stones.

But when the holmium laser energy slowly approaches, each stone shows a completely different reaction.

Hard and dense.

Loose and hollow.

There are even similar infectious stones. Once the surface layer is broken, the system will directly prompt that the operation failed.

Hard calcium oxalate stones, brittle calcium phosphate stones, smooth urate stones, infectious magnesium ammonium phosphate stones...

Almost all common stones in the Department of Urology have appeared in the body of this unlucky patient...

Su Jie gritted his teeth and kept experimenting with the lithotripsy technique taught to him by the boss of the Department of Urology.

…

"Powdering gravel is not as simple as I thought."

Su Jie blinked and started the operation again.

The stones floating in the ureter returned to their original shapes one after another, rising and falling harmlessly between humans and animals, and there was no difference at all to the naked eye.

But Su Jie, who had already been fooled once, did not dare to take it lightly.

This is not a stone, this is a group of duplicitous green tea...

[Stone composition analysis] is turned on.

The stones under ureteroscopy were unmasked one after another. After understanding the nature of the stones, Su Jie used the lithotripsy technique explained by the CEO of the Department of Urology, which became more targeted.

This time, a large number of stones were crushed into fine powder, and the originally clear ureter was instantly stained with a yellow-brown filter.

"After clarifying the composition of the stones, it will be much easier to use the corresponding techniques to crush the stones."

"And for the common types of stones, there are actually only a few most efficient lithotripsy techniques. Now that time is tight, I only need to master those techniques."

As time went by, Su Jie became more proficient in practice, and the yellow powder in the ureter became more fine and less granular.

at this time.

[Ding, the virtual operating room has been open for six hours, host please pay attention to rest]

"The system also has an anti-addiction mode?"

Su Jie was stunned for a moment, then waved his hand indifferently towards the void and whispered thoughtfully:

"buckle."

[Points have been deducted, I hope the host has fun]

The corners of Su Jie's eyes twitched twice, and the heart that had just been warmed by the system became cold again.

"I knew it……"

After deducting the points, the system no longer disturbed Su Jie's practice. There was no concept of time in the virtual operating room. The only thing used to measure the passage of time was the start and end of one operation after another.

Under ureteroscopy, the yellow stones were continuously crushed, the granularity gradually disappeared, and finally completely integrated into the liquid and became part of the turbid liquid.

Su Jie couldn't accurately measure the size of 2mm, but seeing that the remaining stone fragments were completely integrated into the liquid in the ureter, he estimated that it was about the same. At this level, it would definitely be excreted out of the body along with the urine.

The boss of the Department of Urology felt sorry that Su Jie did not have enough time to practice. He felt that if Su Jie had enough time to practice, he would definitely be able to demonstrate a perfect level of lithotripsy for antler-shaped stones.

But how did he know that what Su Jie lacked most was time.

after all.

Can a problem that can be solved using points be called a problem?

[Ding, the virtual operating room has been open for twelve hours. Host, please take a rest]

"buckle."

[Points have been deducted, I hope the host has fun]

"Ah."
Chapter completed!
