Kapitel 893: No Urine

Zheng Ren had a preliminary assessment of the difficulty of this patient's surgery.

Liver hydatid disease, a patient with an autogenous liver transplant, and the System did not even give him a task rating. But this patient actually gave him an S rating.

Was the surgery Grade S?

Zheng Ren was stunned. What was the difficulty? To preserve the kidney?!

He recalled the image of the kidney that appeared on the radiographic films and began to reconstruct it in his mind. Both of the kidneys were severely damaged, and it was very difficult to preserve them. Even with Zheng Ren's own standards, it was indeed very difficult to preserve them.

He had a grandmaster-level skill book in his hands. Once he needed it, he could try to use it. Then, if there was still some time left for the surgical training, and he should be able to complete this surgery.

However, the S-rank surgery was like a lingering shadow that shrouded Zheng Ren's heart.
