Ureteropelvic junction obstruction (UPJ obstruction) is an obstruction at the level of the ureter and renal pelvis. It is the most common cause of hydronephrosis detected in utero and is the most common anomaly detected on prenatal ultrasounds.
The ureteric balloon catheter is intended to cure two major types of diseases: Ureteropelvic junction obstruction (also called UPJ obstruction or Pelvic-ureteric junction obstruction PUJO) [1] caused by intrinsic wall factors as fibrosis and / or hypertrophic wall problems.
Abbreviation Meaning U OSM: urine osmolality UA: urinalysis unstable angina U/A upon arrival UAE: Uterine Artery Embolization (synonym for Uterine Fibroid Embolization) : UBT: urea breath test
Urology, nephrology Hydronephrosis describes hydrostatic dilation of the renal pelvis and calyces as a result of obstruction to urine flow downstream. Alternatively, hydroureter describes the dilation of the ureter , and hydronephroureter describes the dilation of the entire upper urinary tract (both the renal pelvicalyceal system and the ureter).
Contralateral ureteropelvic junction obstruction is found in 3% to 12% of infants with multicystic kidney and contralateral vesicoureteral reflux is seen even more often, in 18% to 43% of infants. Because the high incidence of reflux, voiding cystourethrography usually has been considered advisable in all newborns with a multicystic kidney.
Urology is a medical and surgical specialty that deals with diseases of the urinary tract and the male reproductive system. It overlaps with andrology , and interacts often with nephrology , the non-surgical specialty that deals with kidney disease.
Urology Obstructive uropathy is a structural or functional hindrance of normal urine flow, [ 1 ] sometimes leading to renal dysfunction (obstructive nephropathy ). It is a very broad term, and does not imply a location or cause.
Renal colic, also known as ureteric colic, is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones.The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract.
