Welcome to HCM!
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 pain killers. Also, this stent may harbour bacteria, so you have to take antibiotics, if
fever is there, then higher antibiotics are needed.
Yes, you should drink that amount of water so that at least 2-3 liters of urine is voided in 24 hrs & not more than that.
Take antispasmodics, analgesics, antibiotics with your Urologist's opinion.
Follow up with him for stent removal & further management.
Wish you a good health.
Take care.
Regards.
