Ji Xiang roared as if he had discovered a treasure.

Meng Qingfei ran back quickly, and said as he ran, "Wait for me!" ”

This was said to the patient, and it should not be a very serious patient, so Meng Qingfei wanted to see the discoloration of the urine for the first time.

When he came to the duty room, Meng Qingfei saw at a glance that the urine cup on the table was slowly changing color.

Just as the urine of a porphyria patient turns red, the color of the apple juice coming out of the juicer in front of the patient's urine is gradually changing.

It was as if a drop of black ink had been dripped into the urine, and the black was rippling and gradually dissolving, and I watched the whole cup of urine turn black.

Meng Qingfei glanced at it and immediately took out his mobile phone.

Ji Xiang was speechless about this.

Baidu's medical treatment was originally a mockery, but I didn't expect Meng Qingfei to be tired of it.

Shouldn't we just say what the patient's problem is at this time?

"Teacher Meng......" Ji Xiang said softly.

"Wait a minute, I'll check! The urine color is black, what the hell is the disease? Meng Qingfei said.

"Urinary tumors, this should not be there, but it needs to be carefully investigated. It's really unreliable, Xiaoji, you were the first to train in urology, and now you are doing kidney cancer surgery, have you ever seen black urine? Meng Qingfei took his mobile phone and began to make a differential diagnosis.

Ji Xiang couldn't cry or laugh, if he didn't know Meng Qingfei Teacher Meng, he would definitely think that he was here to be funny.

"No, I guess it's dark red hematuria, described as black." Ji Xiang said helplessly.

"Yes, so this one is excluded." Meng Qingfei said to himself.

"Eating red heart dragon fruit, food containing anthocyanins, eating too much urine will cause redness and blackness, causing changes in the color components of the urine, which can generally be alleviated by reducing the amount of food." Meng Qingfei continued to hold his mobile phone for differential diagnosis.

"It doesn't seem to be either, the patient eats dragon fruit for 3 years? That's so much love. Besides, eating dragon fruit has red bowel movements, and black urine is rarely seen. This one is doubtful. ”

Ji Xiang looked at Meng Qingfei holding his mobile phone and doing differential diagnosis, and felt very interesting.

"Oral administration of Cascara cascara casa, senna, artificial bezoar, metronidazole, sorbitol, methylene blue and other drugs, these drugs contain specific substances that react with the tissues and organs in the human body, making the urine appear black."

"No, Xiaoji, have you heard of a case where eating senna causes your urine to turn black?" Meng Qingfei groaned.

"Nope." Ji Xiang reminded, "Teacher Meng, there are still patients outside. ”

Meng Qingfei slapped his thigh, reluctantly put the mobile phone into the pocket of the white suit, wiped his hands behind his buttocks, and turned around to see the patient.

Ji Xiang thought back to Mr. Meng's Baidu differential diagnosis, and his mood was inexplicably complicated.

But it seems that Mr. Meng has found a breakthrough, Ji Xiang recalled, and found that the focus of the problem was not to do differential diagnosis on the Internet, but to Meng Qingfei found the problem from the patient's underwear turned black, and then observed that the urine turned black.

Generally, it will be washed away after urination, and no one can see that there is a problem with the urine, and if it is not for hospitalization, indwelling catheterization, and urine stored in the urine bag for several hours, it will not be detected at all.

It seemed that the whole step was not difficult, but Ji Xiang knew that there was a chasm here, and Meng Qingfei crossed it directly.

If there are no pre-requisites, even if you turn over the online library, you may not be able to find the answer.

Ji Xiang quietly thought about Meng Qingfei's diagnosis process, compared to the performance of the system NPC who was wise and close to the demon, Meng Qingfei was more like a living person with flesh and blood, a living doctor.

After more than ten minutes, Meng Qingfei walked in happily.

"Xiao Ji! For the first time, I knew that Cascara cascara was actually a diet product! ”

"Uh......"

Ji Xiang saw Meng Qingfei flipping his mobile phone, searching for relevant information about Cascara sagrada.

"Cascara cascara bark and senna are both medicines that cause diarrhea and can also cause dark urine. I haven't heard of it, but if you want to have a similar problem with young women in the future, you have to think of buckthorn. ”

Regarding Meng Qingfei's imaginative thinking, Ji Xiang didn't know what to say.

"Again, metronidazole. I just asked, and the patient has no history of oral metronidazole. ”

"Teacher Meng, I haven't heard that metronidazole can cause discoloration in urine."

"I didn't find it either, the information on the Internet is always true or false, and if I can't find it, I put it there first. Generally speaking, taking metronidazole will cause the urine to darken but turn black, which is a bit excessive. Meng Qingfei said.

"And one more point - rare diseases such as hereditary methemoglobinemia, usually patients have dark urine due to methemoglobinuria."

Meng Qingfei said a very tongue-twisting sentence, and then began to recite.

Ji Xiang was embarrassed and wanted to cover his face.

But Meng Qingfei didn't think there was anything wrong, he recited a large paragraph of medical-related topics and began to log on to various professional websites to find relevant information.

Finally like a professional doctor, Ji Xiang thought to himself.

Because of the constant disturbance of patients, Meng Qingfei spent nearly an hour to sift through two case reports.

Black urine arthritis!

A mouthful and rare diagnosis has surfaced.

Meng Qingfei happily slapped his mobile phone in front of Ji Xiang, "Xiao Ji, look! ”

His finger pointed to a passage, and Ji Xiang looked at it carefully.

[A large amount of urinary melanic acid is deposited in the tissues in the middle and late stages, and extensive pigmentation of the skin can be seen, especially in the ears, sclera, nose, cheeks, etc., which will appear brown or blue-black due to pigmentation, and osteoarthritis can occur in the terminal stage. 】

It took more than five hours from seeing the patient's doubts to finding out the evidence.

In the dead of night, the logical closed loop is finally completed.

Although Meng Qingfei uses a lot of Internet searches, Ji Xiang has a different understanding of his behavior.

"Teacher Meng, it seems that it is really black urine arthritis, exactly the same as what we see."

"There is a precedent for patients to have joint replacements, are you now working with Deng Chaohong in orthopedics?"

"Yes."

"Then I'll talk to the patient's family at night, if they agree to the operation, I'll let the patient go to you tomorrow, and you can take Deng Chaohong to take a look."

"Okay." Ji Xiang simply replied to Meng Qingfei's words, and Meng Qingfei's black white clothes seemed to be radiating light.

Meng Qingfei seemed to be very happy, he reached out and took out a cigarette in Ji Xiang's pocket, and lit one beautifully.

"Xiaoji, I found that your habit of bringing cigarettes is really good. I don't want to smoke more, so I don't bring it myself. Touching a cigarette from your pocket is easy and worry-free, and I'm a little embarrassed to smoke less. ”

Ji Xiang looked at Meng Qingfei, he looked happy, anyway, Ji Xiang didn't see where he was embarrassed.

"Teacher Meng, do you often see a doctor like this?"

Meng Qingfei looked up at Ji Xiang and smiled slightly, "The master has made a move, picking flowers hurts people." Don't stick to one move, just look good. ”
