0.5-1% Pregnancies: Kidney dilation (hydronephrosis, renal pyelectasis) is a common us finding noted in up to 1% of pregnancies. Often times they amount to nothing but in rare cases they're associated with chromosomal anomalies (down's, t21) or genitourinary problems like kinked valves or cysts. These should be followed up with a 3rd tri us and/or genetic testing. ...Read more
The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more
Needs to evaluate:
It is not uncommon to find a condition called vesico ureteral reflux or a narrowing of the drainage portion of the kidney as it meets the ureter or so called upj stenosis.
Both of these would require a pediatric urology opinion.
In the great majority of cases medical treatment and observation over time is all that is required. ...Read more
Hi, My wife is in her 28th week of pregnancy and recent scan shows problem with the fetus kidneys. One of the kidney has multiple cysts and other kidney shows dilation. The reports says: The fetal right kidney measures 52mm in length, shows dilation of p
Cystic kidneys: Sounds like either ARPKD (Autosomal recessive polycystic kidney disease) or renal dysplasia due to obstructive uropathy. Both these conditions are compatible with life depending upon fetal lung maturity. Believe it or not-- you need normal kidneys for lungsto develop in utero. In any case my best advice to you would be to consult with a Pediatric Nephrologist, before the birth of the baby. ...Read more
Both foetal kidneys show mild dilation of pelvis measuring 4-5 mm showed up in 26 week fetus ultrasound Should I be worried?
Fetal Kidneys: Would not be worried with mild dilation of fetal kidneys. This is not an uncommon findings, and usually is not significant. However, your doctor may repeat the ultrasound just to be sure. As long as your growth is fine and amniotic fluid is normal, it's not likely anything to be worried about. ...Read more
What caused my kidney to contract for over 4 hrs after I got my stent removed? I didn't have stones but narrowing and dilation in kidney
Clarify: Do you mean narrowing of the ureter, or shrinkage in the kidney's size? ...Read more
Both foetal kidneys show slight pelvic dilations about 0.3 cm and foetal growth is satisfactory. Duration of gestation is 36+3 weeks. Should I be worried?
Pelvic dilation: Dilation of the pelvis of the kidneys is a fairly common finding and usually is of no significance. It is possible that this represents some sort of uretero-pelvic constriction but if all is otherwise normal in this pregnancy then I would not worry. Ultrasounds after birth can help clarify if this is a problem or not. ...Read more
Hi I'm 20 weeks and 5 days pregnant I had my second scan on Monday and was told 'lt kidney demonstrates mild pelvicalyceal dilation, with AP renal pel?
Consult: Abnormal ultrasound findings are something that you should discuss with your doctor in person. In general the finding of a single anomaly can still be normal, but warrants a more complex discussion with your doctor that includes any serum genetic testing. This is not the end of the world nor anything gravely concerning, but warrant further discussion. Best of luck. ...Read more
I am 23 weeks pregnant and they told me my baby girls kidney is dilated. What are the causes of dilation of kidney and what can be the effects of it?
Fetal kidneys: Mild dilation of the kidneys is common in fetuses and generally is not serious. However more extreme degrees can indicate a condition that needs more careful medical attention. So it depends on the degree of dilation whether to become concerned or not. I recommend that you call and ask for more information from your doctor's office or discuss in detail at your next visit. ...Read more
At 20 week ultrasound, the baby's kidney showed renal pelvis dilation with calyceal dilation at 6 mm for both kidneys. There was no blockage in ureter. Opinions?
No question here: If you are asking "is there blockage in the ureter? " then the answer is possibly. Significant dilation in early gestation increases this risk. It is important to know that dilation (hydronephrosis) can occur without obstruction as well. If the amniotic fluid is low, see a pediatric urologist for prenatal consultation, particularly if you are having a boy (risk of urethral obstruction is high). ...Read more
Can drinking one soda help flush a stone out or would it make the kidney worse? Would it help dilate and help stone move?
Any fluid helps: When trying to pass a kidney stone, drinking extra fluids of any kind increases urine production, resulting in an increased pressure head down the ureter tube to the stone, and dilates the ureter somewhat. All of this facilitates passage of the stone, assuming it is of passable size. Addition of the prescription drug Flomax relaxes the ureter tube and adds to the benefit of extra fluids. ...Read more
My baby boy had bilat hdn before birth. Now usg shows moderate dilation only in the left kidney. Is it harming him? Can he be ok with time?
Yes, it can resolve: Depending on how the rest of the kidney looks, ie whether there is normal growth + surrounding tissue), hydronephrosis of the kidney can resolve. However, it could also get worse if there is obstruction in the ureter (drainage tube). He should be seen by a pediatric urologist and followed with ulstrasound. It is not harmful in and of itself but if the kidney is obstructed it could cause harm. ...Read more
I have been diagnosed with mild calyceal dilation in right kidney suggesting hydronephosis, a 4mm calculus at ureter bladder junction. Is this serious?
Probably not: A Stone in the ureter can cause back pressure in the kidney which results in dilation of the collecting system. The kidney can tolerate this for relatively short periods of time however if this continues it can damage the kidney. I would suggest you consult a urologist. ...Read more
My husband just had a CT scan that showed dilation in one of his kidneys. Does this mean blockage?
Yes: A dilated ureter is the sign of blockage. This can be from anatomic problems, a kidney stone, enlarged prostate or anything pressing on or filing the inside of the tube leading away from the kidney. This needs evaluation by a urologist, the specialist best equipped to investigate this finding. ...Read more
Hysterectomy, esophagus dilation, tube in kidney for stone removal next day. Put to sleep a total of 4 times in 10 days (3 within 5 days). Is that ok?
Yes: If that is what needed to be done to keep you safe then yes but it certainly sounds like you have had a rough week. ...Read more
Urologist saw mild dilation of right kidney and ordered a CT just to be cautious. Had a cytoskopy right before, was normal, bladder was full. Howconcered?
Not to be worried: ct scan will show any blockage lets say from kidney stone which can block release of urine from kidney down ureters to bladder or if at urethra would back up in bladder or if prostate enlarged could prevent urine form getting out thus blowing up the kidney, cystocopy was normal so unlikely stone ...Read more
My UTS resuls" B/L dilation of vessels entering Renal Pelvis, mostly in the right kidney" no masses, and a residual volume of 68 mL, should I worry?
Unclear. ..: What does UTS & B/L stand for? Please clarify them so I or more doc can answer your Q in a clearer fashion. But if residual urine was checked right after you emptied a not severely distended bladder, 68 cc suggests slight bladder weakness to empty, for which you need to be followed closely with possible Rx to ensure no worsening in bladder function over time. Ask Doc... ...Read more
My wife is in 36 th week and she went for scan and it shows fetal left kidney shows isolated renal pelvis dilation measures 8mm. Right kidney appears normal. Both ureters are not dilated- left pelviaactatsis features. Do I need to worry?
Not particularly: The numbers are borderline and not unusual. Baby doesn't make much pee in the womb & it is not appropriate to assess this until baby has been out for a while. I usually schedule a repeat ultrasound before the 2 month visit when these have either normalized or become more definite. The absence of any dilation of the ureters is the best "good" sign. ...Read more
Hydronephrosis: Blockage of the ureter, the urinary passage out of the kidney, can lead to accumulation of fluid in the urinary space called hydronephrosis. This is also called renal dilation or dilatation. Blockage by urinary stones, tumors, valves, or strictures are common causes. Severe urine reflux from the bladder can cause this as well. Over time, unchecked dilatation can lead to decreased kidney function. ...Read more
What to do if I did scan and it says there is mild calyceal fullness/dilatation seen in the lift kidney (?
Likely nothing: The calyces of the kidney fill with urine and drain down the ureter into the bladder. Sometimes they are filled with urine and sometimes they are empty. CT scans and ultrasounds see the kidney in one moment in time. Your calyces were most likely normally filled with urine. ...Read more
Fullness: Dilatation of the renal pelvis can imply some distension of the renal collecting system. Such a finding can reflect reflux of urine up the ureter, a stricture of the ureter, a stone partially blocking the ureter or a manifestation of a renal infection. Sometimes a blood vessel can press on the ureter and cause mild stasis of urine and dilatation or the pelvis. ...Read more

Ultrasound: Ultrasound images may be misleading. It's best to view us over time to be sure there is or isn't a problem. Sometimes something seen on one ultrasound won't be seen again, or be related to an anatomical problem. ...Read more
Interpreting studies: It is not rare to find a prenatal ultrasound that reads"dilation of renal pelvis" or to have one kidney be slightly larger than the other. Since the fetal environment, and demands on the kidneys differ than that of life after birth, I look on this as just something to follow. I get a followup kidney US at 4-6 wks, and most are normal. If not, it suggests a blockage in urine flow. ...Read more
I have sand in my kidneys and dilated pyelon of the left kidney. How is dilated pyelon treated? How to undilated it?
Need clarification: I will have to assume a few things from your post. By "sand" I assume you mean kidney stones. And by "pyelon" I'm assuming renal pelvis, the outlet from where urine leaves the kidney. If it is dilated, there could be a number of reasons. There could be something obstructing the outlet like a stone, or a stricture along the ureter or bladder junction, or something else. Speak to your doctor first. ...Read more
LUTO?: Lower urinary tract obstruction (luto) can present with low amniotic fluid (oligohydramnios), large fetal bladder and hydronephrosis. If bilateral, this is a bad diagnosis with poor prognosis for survival and even poorer for intact survivial and few treatment options with any chance of long-term success. ...Read more
Not fetus---you: Your fetus is pretty well protected. But it is important to keep you healthy as your fetus's health ultimately depends on you. You need to find out why your kidney is dilated with fluid and get that treated. ...Read more

How safe is surgery of hydro nephrons for1week baby. Am 37 wk prgnt &baby's lft kidney is 1.8cm and rt 7.1mm dilated. Dr recomd normal dlvry after 37wk?
I had a renogram done and it showed that my rt kidney was dilated without obstruction. The renal function was also noted as symmetric. What causes thi?
Incidental finding: It is usually the after effects of something that occurred in the past and dilated the collecting system. For example, urinary reflux (where urine can backflowfrom the bladder into the ureter) can dilate the collecting system. It generally occurs in infancy or childhood, can in some cases cause no symptoms, and often resolves. Dilated collecting system can also be congenital) ...Read more
