<s>[INST] i had 2mm of renal calculi at uv junction which caused me a terrible pain and for which i had to get admitted then i was discharged on the same day with some iv fluids and pain killers now i want to know how much time it will require to pass the stone bcoz still i do have some pricking sensation...... [/INST] HIThank for asking to HCMI really appreciate your concern and I would like to say that it is very uncertain that when the stone comes down in to the bladder you need to drink more water that is the best way to bring down the stone, irritation is not the sign of presence of stone, hope this information helps you. take care and have a nice day. </s>
