Dilated Kidney In Fetus
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
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
Dilated Pelvis: Prenatally it is not uncommon to see these things on ultrasound and certainly they need to be followed during the subsequent weeks. But often they resolve and can be minor things. Following by ultrasound is very important and will give the answers you are looking for. ...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
No big deal.: Detecting renal problems by fetal ultrasound is very accurate and efficient because it can prevent serious complications postnatally. Fetal renal pyelectasis or even hydronephrosis is nothing to worry about, provided the amniotic fluid is monitored and remains normal. The neonatology team should be notified at birth to institute appropriate follow-up for the newborn; monthly ultrasounds are needed. ...Read more
25wk fetal boy; us shows eif, and both dilated kidneys 5.2mm/5.8mm pyelectasis, normal quad screen testing, should I be worried? Is this serious?
On the fence. If: There were > 2 markers, especially if they included nuchal thickening ; hyperechoic bowel, your OB would have offered a genetic amniocentesis to rule out aneuploidy, an abnormal # of fetal chromosomes. Ask to see a fetal-maternal medicine specialist who can review fetal growth ; markers, do a super-high-tech fus ; maybe a fetal echocardiogram. Then make an informed decision about amnio. ...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
What does thickening of kidney tissue mean in a 20 week fetus one md says DS the other says it means it's developing. What's your thought?
Here are some...: To save your time and avoid unnecessary worry & anxiety, it would be most beneficial to refer this question to your OB-doc who ordered the test. To interpret prenatal US of a fetus, it is good idea to correlate with your overall clinical picture and other parts of the fetus; at times, a second US in 6-8 weeks may be needed for comparison and deduction of the related clinical consistency. So, ask d ...Read more

In 20w us fetus had echogenic bowel and kidney dilating slower than other. Ds chance s 1:100000.no CF or infection. Baby is normal? Preg time bcms scary.
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
Can a UTI during pregnancy be harmful to the fetus even if it never develops to a kidney infection?
I had ct scan of my kidney last week and after I came to know that I m pregnant of two weeks. Will ct scan affect my fetus. Confused. Help me?
Don't make a habit.: The radiation dose from a single CT scan (1) causes effects which can't be undone, so there's no point in worrying about it, & (2) isn't likely high enuf 2 affect the fetus. That being said, don't make a habit out of getting CT scans. Understand the reasons & ask 4 alternatives. Radiation is different than medicine in that the dose is LIFETIME CUMULATIVE (it's like a medicine that never leaves). ...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
My sister in law's baby died in utero around 16w. No amniotic fluid but she didn't have leaking. They said fetus was dehydrated. How so? Kidney issue?
Could be: Amniotic fluid includes urine made by the fetus during pregnancy.Those that have poorly formed or no kidneys or a severe blockage to their urine outflow, will not create enough amniotic fluid. The fetus remains so tightly shrinked wrapped, that they also can have poor lung growth (no room).These can survive pregnancy but die soon after birth. A loss early in pregnancy may indicate another issue. ...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
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
Yes, but not much.: Transverse fetal lie is unstable and typically converts to either cephalic (head-down) or breech (head-up) in labor. If some uterine/fetal anomaly/tumor prevent this and your baby remains transverse during labor, your cervix will likely open rather slowly and stop at 5-8 cm. This a surgical urgency and cesarean section is required to avoid dire complications such as cord prolapse and fetal death. ...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
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

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
I'm 29 weeks I went to have a ultrasound done & he said my daughter dilated that one kidney bigger than the other. What does it mean?
Perhaps nothing: A dilated kidney on us can indicate a blockage in the ureter from the kidney as well as damage to the kidney. More often than not, however, this is a finding that resolves on its'own over time. It is the cost of of technology--finding things that may ultimately be of no significance. Serial ultrasounds will clarify this. ...Read more
Why the collecting system is minimally dilated and ureter minimally dilated? Is there a risk for kidney failure. Can I take alcohol now.
R-kidney 8.2 cms, l-k 9.0 cms, 7mm calculus at lower polar of r-k, moderate hydronephrosis and parenchymal scars l+r kidneys, ureters dilated. Serious?
Serious...yes: The hydronephrosis part is what makes this serious. The stone is basically plugging the urine outlet and the kidney is suffering. You need to see a urologist and have lithotripsy to break up the stone. At 7 mm it is unlikely to pass on its own. Otherwise you may loose function in that kidney and since you already have some scarring, your kidney function reserve is dwindling. ...Read more
I have few calculi in upper and mild calyx largest measuring 5mm at right kidney. Calculus measuring 4mm in left kidney. Along with left minimal hydroureteronephrosis with dilated entire left uretre.
Your calculi seem not large enough for lithotripsy. These may pass on their own. The passage may be facilitated by placing a stent. It would be prudent to consult a urologist for proper treatment. Left untreated, even stones, this small, can damage the kidney.
Drink enough water every day so that your urine is mostly colorless. ...Read more
