As a Urologist, i can fully understand your concern. The stone needs to be treated. With kidney failure, hes likely to develop bleeding after a surgical procedure.Thats the cause for the blood clots in urine. The stent causes irritation in the bladder. The same with the catheter. Both cause irritation and pain. You have to bear with it. Realize that the stent is temporary and will be removed in short time. His kidney failure will need dialysis, as and when indicated. Wishing your father well. Chat Doctor. Manga.
