[/INST] Hello Sadiqa and welcome to HCM.As an Urologist, i can fully understand your concern.Individual kidney function, is decided on basis of doing, an isotope renogram, blood creatinine and CT-IVU. Have you done theese tests to decide the left kidney function ? Recurrent kidney infections, can lead to kidney decreasing in size and function.Large kidney stones will need repeat sessions of laser fragmentation of stone. But laser treatment doesn't cause damage to kidney, if done properly. High B.P. may be result of the damage to the kidneys, or may have developed due to stress.If you can send the reports and scans, to me as a direct question,i'll clear all your doubts.  Drink 10-12 glasses fluids daily.Dr.Matthew J. Mangat. </s>
