How is PUJ diagnosed?
How do we diagnose PUJ obstruction? Diagnosis is normally made by using an ultrasound scan. This will show up dilatation (enlargement) of the renal pelvis but a normal size ureter. We also perform a special test called a MAG-3 which can show how well the kidney is working and draining.
What is Pelvi ureteric junction?
Ureteropelvic junction (UPJ) obstruction is a blockage in the area that connects the renal pelvis (part of the kidney) to one of the tubes (ureters) that move urine to the bladder. It generally occurs when a baby is still growing in the womb. This is called a congenital condition (present from birth).
What is secondary Pelviureteric junction obstruction?
Secondary UPJ obstruction can be caused by prior surgical intervention to treat other disorders (eg, renal stone disease) or failed repair of a primary UPJ obstruction. This obstructive lesion is usually secondary to ureteral-wall and periureteral scar formation.
How is UPJ obstruction diagnosed?
UPJ obstruction is often diagnosed during prenatal ultrasound, when the enlarged kidney is seen. For those that occur later or are not detected at birth, symptoms suggesting UPJ obstruction include hematuria (blood in the urine), urinary tract infection, kidney infection, kidney stones, and abdominal discomfort.
Can UPJ cause kidney failure?
If undiagnosed or left untreated, chronic UPJ obstruction can lead to significant kidney damage and the gradual loss of kidney function. This is especially true of patients who are diagnosed later in life. Urinary tract infections become common and can be more serious than usual.
How do you get rid of a PUJ obstruction?
A pyeloplasty is a surgical procedure that is indicated for a pelviureteric junction (PUJ) obstruction. The PUJ is the portion of the collecting system that connects the renal pelvis to the ureter. The standard treatment for pelviureteric junction obstruction is open pyeloplasty.
Is UPJ obstruction serious?
Is UPJ obstruction common?
UPJ obstruction occurs in about one of every 1,500 births, and is responsible for about 80% of all swollen urine-collecting systems. Males are affected at more than double the rate of females, and the left kidney is affected about twice as often as the right.
How do you fix a UPJ obstruction?
Peloplasty is a type of surgery that repairs your ureter – a tube that attaches your kidney and bladder. This inpatient procedure, performed by a general surgeon or urologist, corrects ureteropelvic junction (UPJ) obstruction. You’ll likely remain in the hospital for two days.
How do you fix an UPJ obstruction?
The classic treatment for infants is an operation called pyeloplasty. In this surgery the UPJ is removed, and the ureter is reattached to the renal pelvis to create a wide opening. This lets the urine drain quickly and easily. It also relieves symptoms and the risk of infection.
Is UPJ obstruction painful?
UPJ obstruction may also cause pain without an infection. Some cases of UPJ obstruction are not clear. Urine may drain normally at times, and at other times be blocked. This causes pain that comes and goes.
Can a PUJ obstruction cause ureteropelvic stenosis?
Pelviureteric junction (PUJ) obstruction/stenosis, also known as ureteropelvic junction (UPJ) obstruction/stenosis , can be one of the causes of an obstructive uropathy. It can be congenital or acquired with a congenital PUJ obstruction being one of the commonest causes of antenatal hydronephrosis.
What causes stenosis of the ureteropelvic junction?
Left hydronephrosis with severe pelvic dilatation and normal caliber ureter suggesting stenosis of the ureteropelvic junction. CT shows left hydronephrosis with severe pelvic dilatation and normal ureter suggesting ureteropelvic junction (UPJ) obstruction; probably caused by post-surgical adhesions.
How old are the patients with UPJ obstruction?
Between October 1996 and March 1998, we evaluated 20 patients with symptomatic UPJ obstruction by using dual-phase contrast material–enhanced helical CT. Nine male patients and 11 female patients aged 5–67 years (mean, 37 years) were included in the study.
How are the images of the UPJ obtained?
In addition to axial images, coronal, sagittal, and curved paracoronal images along the crossing vessels or the UPJ were obtained by means of multiplanar reconstruction. Crossing vessels were evaluated according to type, position, and association with UPJ obstruction.
