Can stones in the lower left kidney be expelled naturally with Chinese medicine after being shattered?

Patient's question:

Both ureters are patent, and urination is normal. 1 year ago

Doctor's answer:

Currently, there is no ideal method for drug-induced stone removal. If it affects kidney function, treatment is necessary, including extracorporeal shock wave lithotripsy and surgical stone removal. Only if the stone is located at the lower pole of the kidney, without hydronephrosis or significant impact on kidney function, can it be observed with regular check-ups.
