Is having a pretty strong burning in bladder normal after my ureteral stent was removed yesterday.urines brown with blood clots?

Possible, but...: After stent removal, some irritation in peeing is expected but should ease to fade over 1-3 days. As to having clots in urine, it may last off and on until the healing of mucosa of ureter & bladder is completed. If not fading away as usually expected, one still needs to rule out possible UTI. So, if bearable, just watch, wait, and see; if not, seek evaluation, care, & counseling,
