Hello doctor! I have 3 kidney stones (in the renal pelvis 1 tablet 20cm, the upper 2 tablets 15cm and 10cm). In the case, there are 3 stones in the renal pelvis and upper calyx, can the stones be dispersed outside the body? Thank you.

Hello! Indications for surgical removal of kidney stones or ureters (by open surgery or lithotripsy) are based on the following factors:
Symptoms and complications: pain, incomplete or complete obstruction (causing kidney failure), infection ... Size and location of the stone : Stone < 5mm without surgical intervention only medical treatment. Stones of 5-10mm will surgically remove stones when medical treatment fails. Stones over 10mm will be difficult to pass out on their own (with the help of medicine, drink lots of water). Therefore, if there are complications (a lot of pain, obstruction, infection) will have to have surgical intervention (division or open surgery) to remove the stone. The choice of canopy method should be based on size and location. If the stone is large (from 2 cm or more), it is difficult to disperse outside the body, so it is necessary to use percutaneous lithotripsy.
For more in-depth advice, you can go directly to a hospital under Vinmec Health System to be examined by a doctor and give appropriate indications.
