Potassium citrate for UH 600 density ureter stones!

It will be long paragraph, detailed so you can understand my situation!

For the one who really knows and who have experienced it! Can potassium citrate from supplements disolve or erodes a distal ureter stone with the HU density showed on CT scan of about 590-600 HU?? Google searched tells me it is very possible to erode and maybe dissolved smaller one(unde 3 mm), in my case: 6 mm with HU of 592! Mine is lodged in the distal ureter (13 mm from the UVJ) for 2 months! They say that can "silently kill my kidney"(fooooook that, people here shared their stories with 6-7-8mm stones blocked for over 6 months until they passed them darn stones and their kidneys are okay). In those 2 months, i had 2 episodes of very intense pain: first 2 months ago who obviously sent me to ER to found out my stone is in the distal ureter, and one intense pain after 1 and a half month, 5 days ago, who last 7 hours and suddenly disappear! So first, they can "silently kill my kidney" or it depends? And second: the potassium citrate will help erode my 6 mm ureter stone so it can be a little bit smaller so the chances to pass with Silodosin(a better choice, they say, than Tamsulosin) and water?? Thank you for your answers! I want to avoid ureteroscopy cuz i heard the stent after is really worse than stone alone!
