<s>[INST] I had stone in my right kidney and had a laser surgery through my penis. However, the doctor told me that out of 7.mm he could take out 2.5mm fragrance out and the rest approx 5mm is still in your kidney and because my urine pipe is so small he could only have 1 chance to enter. However, he has put JJ Stent in my body and advices for drinking 3-4 liter water per day. I m worried if the stone gets out throughout urine or how. Please advice. [/INST] Welcome to Chat Doctor! If your stone comes out through urine, instead of worrying you should celebrate, because that is what we want. Double J (DJ) stent is put to relieve strain on kidney caused by obstruction, so that urine comes out via stent into bladder. This gives time to ureter, so that its inflammation/edema is reduced, giving better access to stone next time if needed. This stent may cause pain when after urination bladder is empty causing mechanical irritation to bladder mucosa, need not worry, for that we give painkillers. Also, this stent may harbor bacteria, so you have to take antibiotics, if fever is there, then higher antibiotics are needed. Yes, you should Chat Doctor. Take antispasmodics, analgesics, antibiotics with your Urologists opinion. Follow up with him for stent removal & further management. Wish you a good health. Take care. Regards. </s>
