hello Natalie, please dont worry. If i read you correctly you are talking about urethral stone and not ureteral stone. Urethral stones are placed in the passage leading out of the body from the urine bladder. i think u are taking too much trouble. these stones can be easily removed by cystoscopy
(the operation that you fear). there is no cuts and generally the pt can go home in 1 day. i think you should follow the advice of your doctor and get it removed.
