I peed a blood clot, and it feels like I need to pee. I had a UPJ obstruction at 3 months old and 10 months old. What does this mean?

Blood clot in urine. Having obstruction in the urinary tract can cause urinary residual that can lead to crystal deposits, stone formation, bleeding & urinary tract infections. You need to see your 1ry care physician ASAP to get a referral to a urologist, you will need routine U/A, urine culture, blood work for renal functions, electrolyts, voiding cystourethrogram to look for obstructions or vesicouretral reflux.
