8mmx5mm stones may be in the gallbladder, bile ducts, ureters, kidneys, and can be removed by choledochotomy or extracorporeal shock wave lithotripsy.
If 8mmx5mm stones are in the gallbladder with symptoms such as pain and nausea, they can be removed by cholecystectomy. If they are in the extrahepatic bile ducts, they can be removed through choledochotomy, and if they are in the intrahepatic bile ducts with symptoms, they can be removed through choledochotomy.
If the 8mmx5mm stone is in the kidney, the stone can be broken by extracorporeal shock wave lithotripsy and then excreted from the body with urine. If the 8mmx5mm stone is in the bladder, it can be passed out using transurethral cystoscopy to remove or crush the stone.
In case of stones, it is advisable to visit the hospital and get them removed in a proper way.
