Is bladder stone curable?

Very curable: Most bladder stones can be broken up into little pieces or dust by endoscopic laser or lithoclast lithotripsy (breaking up stone by laser or "jackhammer" type instrument passed via cystoscope). Broken pieces or "dust" can be irrigated, juctioned out or remaining small pieces grasped. Very large stones (> than an egg) are sometimes best removed by open surgery. Patient cured then prevent new ones.

Kidney stone.: Kidney stones up to 5mm in size will predictably pass on their own. Just drink plenty of water so you produce a lot of urine, dilate those ureters and allow the stone to pass. It may hurt while it's on its way out, but it'll pass. Bigger stones will likely get stuck and will cause tremendous pain and will have to be removed by lithotripsy or cystoscopy. Stones in bladder should pass.
