Urinary Bladder?: If you mean the urinary bladder see a urologist who can discuss options with you.

Cholecystectomy: In most cases, the gallbladder is removed, since chemical stone dissolution does not work well. Could consult a GI dr for opinion / options, but will likely recommend either wait-n-see or pre-emptive gallbladder removal by a surgeon.
