I got a kidney stone prodecure done in june 2017 as i had stones in my gall bladder. Upon lasik the stones moved to my urinary pipe and got blocked there and would not come out even with saline treatment. So i had a stint procedure. I am fine now but i just want to know it i need to get ultrasound done on any regular basis ad kidney stones in gall bladder go undetectable. If yes , which ultrasound do I need to get done and how often.(once a year, once in 6 months)
