Pelvi-ureteric junction obstruction in adults
Written in association with:Pelvi-ureteric junction obstruction (PUJ) isn’t just a condition in babies; adults can experience it, too. If it isn’t tended to, it can lead to kidney damage.
In this article, highly-skilled consultant urologist Mr Chris Blick provides an informative guide to PUJ, its causes, symptoms and treatment.
What is pelvi-ureteric junction (PUJ) obstruction?
This condition exists when the drainage of urine from the kidney into the ureter (tube that connects the kidney to the bladder) is obstructed. This causes dilatation or swelling of the renal pelvis (the part of the kidney into which urine drains).
PUJ obstruction can cause:
- pain in the side of the back, which is often worse after drinking a lot of fluid or alcohol
- urine infections
- kidney stones
If left untreated, PUJ obstruction may cause the obstructed kidney to lose function.
What causes this condition?
The condition may be something a patient is born with (congenital) or something that develops during their life (acquired). PUJ obstruction can be caused by a weakness in the wall of the ureter, compression from a blood vessel supplying the kidney or from scar tissue which may have developed following trauma, infection or kidney stones.
Is PUJ hereditary?
PUJ obstruction is not a condition passed on from parents to their children.
Is PUJ obstruction curable?
In many cases treatment may not be necessary, however in cases that do require treatment the success rates are more than 90 per cent.
Is a pyeloplasty a safe procedure?
Pyeloplasty is a safe and effective treatment for PUJ obstruction, usually carried out as a robot assisted laparoscopic or keyhole operation. Immediately after the operation, some patients may suffer from temporary shoulder tip pain and abdominal bloating.
Patients will be in hospital for an average of one to two nights, the risk of requiring a blood transfusion is less than two per cent and most patients will be fully recovered within four weeks.
