Urine tested positive for blood said its normal for patients that had radiation therapy for prostate cancer also are ther any cancer cells in urine bl?

Possibly: Radiation therapy can cause inflammatory changes in the bladder which can result in microscopic blood in the urine. However a urine cytology should be performed to rule out possibly bladder abnormalities. Additionally, if the history of radiation therapy is in the past, then a cystoscopy (camera to look in your urethra and bladder) may be warranted. Please discuss further with your doctors. ...Read more

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body.

Where is the blood coming from if I have moderate microscopic hematuira on every UA but NO RBC &otherwise normal UA except trace ketones. Have lupus,?

In females: may be related to menstrual cycle; however in lupus you will need specific testing and a renal ultrasound as well as a 24 hour hrs analysis. This can often be a normal variant and the trace ketones suggests inadequate hydration. Try to consume 8-10 8 oz glasses of fluid daily. ...Read more

I have foamy urine but my recent urinalysis test says there is no protein in my urine although i had traces of protein in my urine some time ago. i repeated the urine test a week later and there was no more protein in my urine but urine still foamy?

I have  foamy urine but my recent urinalysis test says there is no protein in my urine although i had traces of protein in my urine some time ago. i repeated the urine test a week later and there was no more protein in my urine but urine  still foamy?

Foamy urine: Very rapid urination/strong force can cause foam/bubbles in the urine. If that is the case, it may persist as long as you pee hard and fast. The only other significant cause of foam is proteinuria. If the urine dipstick test remains negative for protein, you're in the clear, but with your history, periodic testing is advised. ...Read more

Traces of blood found in urine sample, xray showed some white spots in pelvis, but was not told what it could be?

Your job: ask & work: to understand. It is your body; not that of others who primarily focus on their priorities (human nature for all of us). X-Ray=Hi-frequency electromagnetic radiation, i.e. above light frequencies & simply show shadows, bone vs. water density (tissue) vs. air. White spots are likely bone (absorb/block A-Ray from reaching/exposing the film). Is blood from urinary bladder or kidneys? big difference! ...Read more

Have uti symptoms had test shows white cells in urine and blood yet the urine culture shows no uti have back pain too what could be wrong?

Have uti symptoms had test shows white cells in urine and blood yet the urine culture shows no uti have back pain too what could be wrong?

Probably still UTI: Hi Jessi, It certainly sounds as if you have a UTI. A urine culture can be falsely negative, as can any lab test. Were you taking antibiotics when the culture was done, causing a negative culture? Other possibilities are urinary tract stones and bladder tumor. I suggest rechecking the urinalysis and culture, and then see your doctor or a urologist to help you look into it further. Good luck ...Read more

Is this new?: You'll do well to have a follow-up, probably with imaging. Many people have this for a lifetime with no problems -- these people often have a mutated collagen gene that allows red cells to pass through the little filters in the kidneys. However, this finding is worrisome for stone, tumor etc if its a new finding at your age. Best wishes. Usually these things are manageable. ...Read more

Micro hematuria: Microhematuria in a 34 year-old female who has never smoked is not very likely to be due to bladder cancer. Bladder cancer is not really genetic in nature. Despite that, you should have a hematuria workup which would include imaging of your kidneys as well as a cystoscopy and a variety of possible urine studies. ...Read more

UTI: Blood in urine has many causes, one of them is UTI. The culture can sometimes be negative, however if you still have symptoms, then a second sample of urine should be submitted for culture. Also, the doctor needs to look for other causes of blood in the urine such as glomerulonephritis, Ig A nephropathy, etc. ...Read more
