Kidney stone of 12mm size?

Kidney stone of 12mm size?

Yeah, that's big.: A stone up to 5mm in size will predictably pass, with variable degrees of pain. A 12mm stone is going to get stuck if it decides to move out of the kidney. You should get that stone managed before it starts to move. ...Read more

Case of PUJ stenosis Rt side,Rt moderate hydronephrosis with reduction of renal parenchymal thickness 7mm & 1.4cm stone in lower calyx of Rt kidney. ?

Here are some ...: Apparently, the condition of your right kidney has been chronic, most likely, inborn. From what you described, this kidney may be still salvageable by surgery – either open or laparoscopy with or without robotic assistance. I'm sure, before the procedure, a renal nuclear scan can be done to define the residual function of right kidney. For more detail, ask and talk with your doctor. Best wish. ...Read more

Leftkidney measures11.3x5.5cms enlarged in size rightkidney 9x5.5cms 
perapelvic cyst leftkidney causing mild calyectasis.Multiple renal cortical cys?

Multiple kidney cyst: The vast majority of renal cysts and benign simple cysts which are a symptomatic and causes no problems. It is not the same as polycystic kidney disease, where many cysts on both kidneys could lead to kidney failure. An ultrasound can determine if these are simple vs complex cysts, the latter could be worrisome. I suspect the kind you have could simply be followed over time; urologist will guide. ...Read more

Echogenic calculus of size 3mm noted in lower calyx. echogenic calculus of size 5mm noted in the mid ureter. Taking drotin DS now. Is surgery required?

Echogenic calculus of size 3mm noted in lower calyx. echogenic calculus of size 5mm noted in the mid ureter.
Taking drotin DS now. Is surgery required?

Not necessarily: Surgery, usually endoscopic (using "scopes"), is only needed if stone is causing pain, too big to pass (usually >or= to 5 mm), or associated with blockage of ureter(blocking flow of urine) or associated urine infection. Most likely if stone is free in calyx it will pass on its own. If attached it may or may not cause symptoms. If no sxs may watch. Follow up with primary MD and/ or urologist. ...Read more

10mm and 9mm kidney stones are normal size stones?

Bilateral lithiasis left kidney measuring 11 mm in pelvic ureter junction WBC 20-25 in urine?

Bilateral lithiasis left kidney measuring  11 mm in pelvic ureter junction WBC 20-25 in urine?

Here are some...: The odd to pass a 4-mm stone through ureter to bladder in 2 weeks is about 75-85%; for a 11-mm one, its odd to pass should be next to zero. Finding 20-25wbc indicates significant inflammation most likely related with stone-related irritation to the lining of urinary tract. So, intervention at convenient time is advised as long as being tolerable and of no fever. More? Ask treating urologist timely ...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

Kidney stone in lower pole of 10.5 mm?

Won't Pass: The stone is too big to pass. It may never bother you if it stays in the lower pole. If it moves it will obstruct and will require an intervention. Try and find out why you make stones since uric acid stones can shrink in an alkaline environment. Also, if the stone is calcium decreasing urinary calcium may prevent the stone from enlarging. See a urologist, lithotripsy may be of benefit. ...Read more

In my kidney ultrasound the result is normal size of kidneys with bilateral diffuse parenchymal disease,normal sonogram of the urinary bladder.

Here are some…: Minimal hydronephrosis could be just a radiologist's subjective impression, but may not be related with a 5-mm non-obstructing stone. However, the key point still lies on how to manage this 5-mm stone, which can be deduced by analyzing the past history of stone activity and balancing medical necessity and professional possibilities. So, consult urologist timely. ...Read more

Kub ultrasound finding of anechoic focus at the middle pole measuring 1.5x1.5cm, left kidney. Minimal pelvocaliectasia right kidney.What treatment?

Kub ultrasound finding of anechoic focus at the middle pole measuring 1.5x1.5cm, left kidney. Minimal pelvocaliectasia right kidney.What treatment?

Probably benign: A description of an anechoic focus in the kidney typically refers to a cyst or a cystic lesion. Minimal pelvocaliectasis typically refers to very mild dilatation of the pelvis & calyces which is where urine drained into before it flow out into the ureter. These findings do not sound concerning as pelvocaliectasis may occur when you have a full bladder. Please check with your doctor to be sure. ...Read more

Can small renal stone 6 mm cause painless macroscpical hamaturia?

Yes, it can be but..: The presence of kidney stones has been known to be one of the causes for painless microhematuria, and at times, urinalysis (some 5% of times) may be normal even while stone is moving through the ureter with pain. But painless macroscopic hematuria could mean you have seen gross bloody urine with no pain as described; if so, you should be evaluated for painless gross heamturia ASAP.
