Ultrasound for Hydro nephrosis diagnoses

Ultrasound for Hydro nephrosis diagnoses 

 Hydronephrosis is defined as the

dilation of the urinary collecting 

system of the kidney due to obstruction we can see the psoas muscle and we see

the dilated renal pelvis of the right 

kidney following the identification of

hydronephrosis we must investigate 

further to find the underlying cause there are many possible causes for this

obstruction including Ural Elias's 

ureter pelvic Junction obstruction and malignancies such as cervical cancer and retroperitoneal fibrosis in ultrasound a dilated renal pelvis and dilated calluses lead us to the diagnosis of hydronephrosis the large eco free the structure here in the middle of the kidney is the renal pelvis here you can

see the fluid-filled calluses suggesting 

hydronephrosis if the ureter is dilated as well like here, we say it is hydro

ureter and Neph roses there are four 

grades of hydronephrosis take a second to look at this image this is a long

the section over the right kidney showing 

also, the liver here we have grade one hydronephrosis in the renal pelvis is dilated more than five millimeters and echo-free fluid can be seen in the calluses but there's no callous dilation the renal tissue is normal in grade one hundred neuroses we see dilation of the renal pelvis and fluid marked calluses like here the calluses themselves are not dilated take a second to look at this image this is a long section over the left kidney showing the spleen and the vertebral column bordering the left kidney here we see the echogenic the structure which is the stone in the renal pelvis in grade 2 hydronephrosis.

we have a dilation of the renal pelvis

the infant Ebola and the calluses

we have no tissue atrophy here's an 

example of the dilation of the renal pelvis the infant Ebola and the calluses

we have no tissue atrophy we see the 

echogenic stone formation in the renal pelvis with its acoustic shadowing and we can also see a double Jay catheter that was installed to relieve the hydronephrosis take a second to look at this picture in Grade three hydronephrosis received dilation of the

infant Ebola and the calluses as well as 

the renal pelvis the renal silence is completely occupied by dilated structures there's blunting of the furnaces and there's mild cortical thinning here we see a moderate dilation of the renal pelvis, we see a loss of calyx borders right here than the blunting of the furnaces and we see

cortical thinning take a second to look 

at this image in this long section over the right kidney, we can see an example of great for hydronephrosis due to an including stone in the yurt or pelvic.

Junction in the ultrasound image we can 

see an extensive dilation of the renal pelvis and calluses which appear

ballooned we can see the loss of borders 

between the renal pelvis and the

calluses and we can see renal atrophy as 

well as cortical thinning take a moment to look at this picture

so if we see hydronephrosis we have to 

investigate the reason as we said before the most probable reason for hydronephrosis is occluding kidney stones especially when it's acute onset with right or left flank pain in this

the long section on the right kidney we can 

see an occluding stone with acoustic  shadow within the proximal part of the ureter here we see the dilation of the renal pelvis and the proximal ureter the

ultrasound image shows the dilated renal 

pelvis here and the dilated proximal

ureter going up to the occluding stone 

which is here which is the echogenic

the structure here forming the acoustic 

shadow take a second to look at this image another benign reason for hydronephrosis is a year 2 pelvic Junction obstruction it is caused by an accessory lower renal artery crossing the renal pelvic junction of the right kidney in this cross-section over the right kidney we can also see the psoas muscle in the] ultrasound image we can see the renal artery obstructing the ureter pelvic

junction right here we use Doppler to 

investigate the vessel takes a second to look at this now this is alive

presentation of hydronephrosis we see 

dilated renal pelvis structures you see dilated calluses we've seen no cortical thinning but a small bit of free fluid around the right kidney now when we look for the reason for the hydronephrosis we have to go down to the pelvis we see the bladder right here the uterus right here

and then we see a dilated ureter coming

down here and suddenly there's this

echogenic structure right in the lumen

of this dilated ureter which is the

occluding stone and the reason for the

hydronephrosis
