What does UPJ obstruction feel like?

In infants, symptoms of UPJ obstruction may include a mass in the abdomen, blood in the urine, and failure to thrive. Older children and adults may experience intermittent flank pain that worsens with caffeine consumption (or alcohol in adults) and nausea and vomiting.

Can a UPJ obstruction come back after surgery?

Once the UPJ obstruction is fixed, it almost never comes back. Note that patients who have had UPJ obrstruction may have a slightly greater risk of future kidney stones or infection. This is because the kidneys may still contain some pooled urine, even though overall drainage is improved.

How is ureteropelvic junction 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 hydronephrosis cause kidney failure?

Severe cases of urinary blockage and hydronephrosis can damage the kidneys and lead to kidney failure. If kidney failure occurs, treatment will be needed with either dialysis or a kidney transplant. However, most people can recover from hydronephrosis if treated promptly.

How do they fix a blocked kidney?

Your doctor (urologist) may recommend: A ureteral stent, a hollow tube inserted inside the ureter to keep it open. Percutaneous nephrostomy, during which your doctor inserts a tube through your back to drain the kidney directly.

How do you fix an UPJ obstruction?

Most cases of UPJ obstruction actually do not require surgery and resolve on their own. However, if patients exhibit pain, recurrent infections, evidence of worsening function or increasing swelling, they may require a surgery called a pyeloplasty to prevent kidney injury and correct the blockage.

How do you fix a blocked kidney?

Treatment

1. A ureteral stent, a hollow tube inserted inside the ureter to keep it open.
2. Percutaneous nephrostomy, during which your doctor inserts a tube through your back to drain the kidney directly.
3. A catheter, a tube inserted through the urethra to connect the bladder to an external drainage bag.

What are the stages of hydronephrosis?

Hydronephrosis grading (SFU system)

1. grade 0. no dilatation, calyceal walls are apposed to each other.
2. grade 1 (mild) dilatation of the renal pelvis without dilatation of the calyces (can also occur in the extrarenal pelvis)
3. grade 2 (mild)
4. grade 3 (moderate)
5. grade 4 (severe)

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 common is UPJ obstruction?

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.

What are the symptoms of kidney obstruction?

Signs and symptoms depend on where the obstruction occurs, whether it’s partial or complete, how quickly it develops, and whether it affects one or both kidneys. Signs and symptoms might include: Pain. Changes in the amount of urine produced. Difficulty urinating. Blood in the urine. Repeated urinary tract infections.

What is treatment for kidney obstruction?

Modern treatments for kidney obstruction can be carried out through laparoscopic surgery. This greatly reduces the risks that patients face from surgery, as well as the amount of rest required before resuming normal activities, while providing effective treatment options to patients.

What happens to the kidney if the ureter is blocked?

A blocked ureter can cause urine to go back up into the kidney, which causes swelling. This backflow of urine is known as Vesicoureteral Reflux A condition where there is backward flow of urine from the bladder into the kidneys. (VUR). Other potential causes of a blockage include: a kink in the ureteropelvic junction, which is where the ureter meets the pelvis of the kidney.

What are symptoms of renal obstruction?

Another cause of kidney obstruction is a tumor. The tumor could be in the affected kidney itself, in the ureter or in the abdomen in a place where it puts pressure on the kidney. Symptoms of a tumor include flank pain, a lump in the abdomen, weight loss, fatigue and possibly fever.
