Does hydrouteronephrosis due to renal calculi cause damage to kidney?

Only if prolonged. Hydronephrosis can cause temporary decrease in function of the kidney due back pressure. However, in the long term there should not be any significant effect on kidney function if the obstruction is relieved and there is no associated infection.

Husbands ultrasound keeps finding renal calculi in both kidneys. He has No symptoms though. He drinks lot water daily and lemon but still gets stones??

Get 24 hour urine. If your husband has had issues with stones then he should undergo a metabolic evaluation including blood tests and also a 24 hour urine collection to determine his stone risk factors so that prevention can be optimized. He also may need additional imaging as ultrasound does not provide as high a resolution to accurately size stones and pinpoint locations. See your urologist . Read more...

no cancer. Renal cysts are very common and nothing to worry about. The subtle hyperechoic foci probably represent tiny kidney stones which may grow over time. No hydronephrosis means no evidence of something obstructing the flow of urine to your bladder. No masses means just that. Please see your doctor to review this report as well as current laboratory tests of your kidney function. Read more...
Probably fine. No hydronephrosis and no masses is normal, so these are both good. Renal cysts are very common and usually benign (ask if they are simple cysts). Small hyperechoic foci sounds like small kidney stones, but these do not cause pain unless you are passing one (would have hydronephrosis). A noncontrast ct scan is best to evaluate kidney stones but does involve radiation. See a urologist. Read more...
