Patient's question:
Carefully check if the blood can reveal kidney failure? I have a 1.0×0.5 renal cyst in my left kidney. When I gently press my left kidney with my hand, it aches a bit. Also, twisting my waist sometimes causes a slight pain, though not very noticeable. My right kidney is fine. If I run too long (about 2 kilometers), my left kidney feels very tired. Am I suffering from kidney failure?Doctor's answer:
Some conditions are secondary to kidney failure, such as your kidney cyst. This is not a problem—it will never lead to kidney failure. You should go to a regular hospital and see a urologist for a thorough examination. If everything is fine, you can put all your worries aside. If the cyst diameter is less than 4 cm and there are no special discomforts, treatment is not necessary for the time being. Regular follow-up checks should be scheduled. If the cyst is larger, if it causes secondary infection, rupture, or increased kidney pressure, treatment should be sought in the urology department. Your condition has nothing to do with kidney failure.
