Hello, Thank you for your question and welcome to Health Care Magic. I read carefully your query and I understand your concerns. In my clinical practice, I have not been familiar with Ayurveda Medicine, however, yes, kidney stones, even big sized can be removed without having surgical intervention. With such a presentation on my clinic I would recommend to your mother Extracorporeal Shock Wave Lithotripsy (ESWL), which is the most frequently used procedure for the treatment of kidney stones. ESWL uses shock waves to break a kidney stone into small pieces that can more easily travel through the urinary tract and pass from the body. After ESWL, stone pieces usually pass in the urine for a few days and cause mild pain. Beside this treatment option, I would recommend to your mother to drink plenty of water, in order to help the stone fragments pass through the urinary tract easily. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Kind Regards, Dr. Ina
