<s>[INST] Hi, my wife (25yrs) has stone in her right kidney of 9mm size. This was diagnosed 4 months back by ultrasound. That time she was not experiencing any problem. Doctor told to let it there and suggested some do s & don ts. Yesterday, she had severe pain in her lower right abdomen. Local doctor given some injection to relieve. I wanted to know, what are the options for her kidney removal with minimal surgery. Thanks in advance! [/INST] Hi, Thanks for using Chat Doctor. Q. what are the options for her kidney removal with minimal surgery? Shock wave lithography. It uses sound waves to create strong vibrations (shock waves) that break the stones into tiny pieces that can be passed in your urine. This can cause moderate pain, blood in the urine and discomfort as the stone fragments pass through the urinary tract. If not successful then surgically can remove stone using small instruments inserted through a small incision in your back. Discuss with your doctor for the same. Hope I answered your question. Feel free to ask me if you have any further queries. Wish you good health. Take care. Regards </s>
