Why are my large nonobstructing bilateral renal calculi that aren't supposed to cause pain causing me great pain?

Why are my large nonobstructing bilateral renal calculi that aren't supposed to cause pain causing me great pain?

Needs eval: Your pain should be evaluated and you have a right to a diagnosis that explains the pain. However, the pain is not coming from non-obstructing renal calculi. Consider other causes of bilateral back/flank pain. Remember, non-obstructing stones can dislodge and become very painful when they are being passed. I hope this helps. ...Read more

I hav bilateral renal calculi since 5 years. As of now in my right proximal ureter I hav a 7mm stone causing hydrouteronephrosis please suggest a cure?

I hav bilateral renal calculi since 5 years. As of now in my right proximal ureter I hav a 7mm stone causing hydrouteronephrosis please suggest a cure?

Urologist: Unfortunately, there is no easy "cure" for a 7 mm proximal ureteral stone. You have a small, but not zero, chance to pass this on your own, but even if you can, it will be painful and may cause you to miss substantial amounts of work or school. You need to see a urologist to discuss your options, which fortunately are minimally invasive in most instances. Good luck! ...Read more

I have non obstructive renal calculi between 3 to 4mm. I have no pain. Is it anything to worry about? Any treatment to get it removed?

See remark: A stone that size may stay there BUT can increase in size with time. It can drop down the ureter, and that cause agonizing pain. Drink gererous amount of water. Drink one glass of lemonade in am & one in pm. Lemonade won't dissolve stones but help prevent them. If your job entails travelling/flying consult with a urologist best regards ...Read more

Lots of water: You need to make sure that you drink enough water each day so that your urine is watery. The stones may pass out on their own, but is generally a painful process. One consideration is to consult a urologist to see if the stones need to be removed by endoscopy. ...Read more

Why UTI &bacteriia can lead renal calculi?

Why UTI &bacteriia can lead renal calculi?

Struvite stones.: The only causative link between UTI and kidney stones is in the formation of struvite, or magnesium ammonium phosphate, stones. These stones form when there is high ammonium phosphate and high urine ph. The only situation in which this occurs in humans is with a urinary tract infection with a urease-producing organism, such as proteus or klebsiella, which breaks down urine urea into ammonia. ...Read more

Is it normal to have multiple tiny punctate renal calculi in both kidneys with no obstruction...And still have severe back pain?

Is it normal to have multiple tiny punctate renal calculi in both kidneys with no obstruction...And still have severe back pain?

Unrelated: Many people have tiny punctate renal calculi and are asymptomatic because of small size, location, and absence of obstruction and it would be highly unlikely that any back pain, especially severe back pain, would be attributed to these stones. In addition, these punctate stones are often in such a location that they are not accessible to treatment via eswl or endoscopy. ...Read more

I am feeling burning pain during urination. Previously sufferer of renal calculi but now USG is ok. Is it a UTI. I have given urine sample for culture.?

I am feeling burning pain during urination. Previously sufferer of renal calculi but now USG is ok. Is it a UTI. I have given urine sample for culture.?

Likely UTI: You have done the correct thing by getting a urine culture this will show whether or not you have a uti. A routine urinalysis might well have demonstrated a UTI if the nitrite reagent was positive. In the meantime you could be started on an antibiotic, which could always be changed if your UTI has been caused bty a resistant species of bacteria. Good luck. ...Read more

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??

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

Subtle hyperechoic foci in both kidneys, probably renal calculi. Left renal cyst measured 17mm. There is no hydronephrosis or other masses. What does this kidney ultrasound mean?

Subtle hyperechoic foci in both kidneys, probably renal calculi. Left renal cyst measured 17mm. There is no hydronephrosis or other masses. What does this kidney ultrasound mean?

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

Is it poss for radiologist to miss bilat renal calculi on a CT? What should pt do w/ micro & gross hematuria >yr (& cola colored urine)? give up?

Hematuria: Anything is possible but calculi are usually easy to see on a CT. Blood in the urine can be caused by many things including infection, stones, kidney diseases, muscle damage and others. We usually do blood tests to check kidney function, urine and often a CK to look for muscle damage. If those tests don't pinpoint the cause they at least help decide the next step. ...Read more
