Why does my right kidney hurt when I pee?
I am not sure what is your age, but there could be reflux. You need to get checked out by a Urologist to ensure you don't have vesicoureteral reflux. You need to check your urine to make sure you don't have urine infection. Also, would get a renal ultrasound to make sure you don't have hydronephrosis or kidney stones, or to make sure you don't have a kidney mass (less likely). READ MORE
Can a kidney infection go away on its own?
It could go away if it is mild, if you don't have an underlying kidney or bladder disease, or urinary tract blockage or kidney stone, and if you drink lots of fluids to flush it out. Despite that, there is no guarantee of resolution. Continued caution should be exercised, and if having urinary symptoms, check with your doctor to get it treated. READ MORE
Which food reduces your creatinine level?
No food reduces creatinine, but low protein diet is indicated for those who have kidney disease to reduce the work load on the kidneys and decrease the rate of kidney function decline over time. READ MORE
How long does kidney dialysis take?
Three to four hours, usually 3 times per week if doing hemodialysis. If doing peritoneal dialysis, it is daily overnight. READ MORE
Will antibiotics kill a kidney infection?
Antibiotics are used to treat infections. There are different antibiotics for different types of infections. Using the right antibiotic, for the sufficient duration of time, you will successfully kill a "kidney infection." Urinary infections are classified as lower infections (Bladder infection) or upper infections (kidney infection). The upper infection is more dangerous and would require IV antibiotics initially, and longer course of treatment in comparison with lower urinary tract infection. READ MORE
UTI medication?
Cipro is usually a good antibiotic for urine tract infection. If your doctor prescribed it for you then you need to continue the course unless you have allergic reaction to it. A simple UTI is usually treated with a short course of Cipro like 5-7 days. The dose of Cipro depends on the severity of the urine infection and how good the baseline kidney function is. READ MORE
