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?

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

See professionals...: See an well-experienced urologist to decide if it's necessary to intervene; if needed, at what price? For your condition, a professional needs to share the balancing thought on the need and possibility of care before committing its removal, which usually can be done through the penis with fine scope and laser. For detail, check with experts. Best wish ... ...Read more

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

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 is severe fetal hydronephrosis?

What is severe fetal hydronephrosis?

Trapped urine.: Severe fetal hydronephrosis is diagnosed when urine is trapped inside the renal collecting system of a fetus with resultant destruction of kidney tissue. It can be due to stenosis or obstruction at various points in the urinary tract and merits postnatal antibiotic uroprophylaxis and imaging. Bilateral severe cases may cause oligohydramnios and fetal lung hypoplasia or demise. Seek mfm care asap! ...Read more

Male fetus ultrasound (35w 4d) which showed an enlarged fetal bladder. Normal amniotic fluid and kidneys. Is this typical in third trimester?

Male fetus ultrasound (35w 4d) which showed an enlarged fetal bladder. Normal amniotic fluid and kidneys. Is this typical in third trimester?

Specific case: This is a very specific case that requires a doctor to evaluate the exact findings of the sonogram to determine if it is normal or not. You will need to seek clarification from your doctor regarding the term “enlarged bladder” to determine if further testing, follow up sonograms or a referral to a perinatologist is indicated. ...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

What is mild pelvic dilatation on right kidney ultrasound in adult woman?

What is mild pelvic dilatation on right kidney ultrasound in adult woman?

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

Prosterior urethral valves in fetus, what is this?

Prosterior urethral valves in fetus, what is this?

PUV serious problem: Posterior urethral valves cause severe urinary tract obstruction. They are located at level of external urethral sphincter, distal to bladder neck & prevent urine from passing. Can cause severe kidney damage before birth, as evidence by kidney swelling (hydronephrosis). Bladder & bladder neck can be greatly thickened & first part of urethra, before valves is widely open. Treated by resection. ...Read more

Is calcification in kidney arteries ok?

Is calcification in kidney arteries ok?

Depends how much: I assume somebody saw calcification on an x-ray. Unless it's a tiny amount, it means you have early atherosclerosis (hardening of the arteries). Calcified arteries at age 30 are worrisome and suggest at some point blood flow could be reduced to your heart and other organs. Is your blood sugar, blood pressure or cholesterol elevated? Have a physician check out your metabolism. Avoid junk food. ...Read more

What to do if I'm 35 weeks pregnant and my ultrasound says mild polyhydramnios with bilateral fetal dilated renal calyces?

Talk to your doctor: Depending on other clinical factors, mild polyhydramnios and mild dilated calyces may be within normal limits, but could be markers for a high risk delivery and underlying fetal problems. This cannot be answered in a forum. Your doctor needs to evaluate all the parameters. ...Read more
