What is Pelvicaliectasis of the kidney?
Pelvicaliectasis is a term used to describe a dilated renal pelvis and calyces. It is not synonymous with the word hydronephrosis. Hydronephrosis is a term used to describe a dilated renal pelvis and calyces that are specifically caused by an obstructive process.
What does mild Pelviectasis mean?
The funnel-like structure that drains the kidney is called the renal pelvis. If it appears abnormal or dilated, it is measured. Mild dilatation of this renal pelvis, also called pyelectasis or pelviectasis is defined as a measurement between 4mm and 10mm in the second trimester.
Can pyelectasis be cured?
Pyelectasis will resolve spontaneously more than 90 percent of the time. If the blockage is more severe, your baby may need follow-up care and possibly surgery after delivery. If the obstruction is more severe, urine may back-up and collect in the kidneys. This is called hydronephrosis.
What causes mild renal Pelviectasis?
Common pathologic causes include vesicoureteral reflux (the most common etiology), ureteropelvic junction obstruction, ureterovesical junction obstruction, multicystic dysplastic kidneys, and posterior urethral valves. Although some conditions can be diagnosed antenatally, in most cases a diagnosis is made postnatally.
What is pelvocaliectasis?
Dilation of the pelvis and calyces of one or both kidneys resulting from obstruction to the flow of urine. Synonym(s): pelvocaliectasis, uronephrosis.
What causes pelvicaliectasis of the kidney?
Many causes: Pelvicaliectasis of the kidney is dilation of the spaces in the kidney where urine goes prior to passage into the ureter (kidney tube) and bladder. This can indicate a possible obstruction downstream from the kidney (stone or congenital narrowing of the ureter) or possibly can be a normal anatomic variant.
