Pelviureteric junction (PUJ) obstruction/stenosis, also known as ureteropelvic junction (UPJ) obstruction/stenosis, can be one of the causes of obstructive uropathy. It can be congenital or acquired with a congenital pelviureteric junction obstruction being one of the commonest causes of antenatal hydronephrosis .

4 c-d) and 3D-CTV (Fig. 4 e-g) with bone remodeling revealed the bilateral IJV J3 segment was compressed by elongated styloid process and transverse process of C1 vertebra. OBJECTIVE. The objective of our study was to evaluate which spectral Doppler ultrasound parameters are useful in patients with clinical concern for transplant renal artery stenosis (TRAS) and creat Video Transcript. Spinal stenosis is narrowing of the spinal canal. It is often multi-factorial and involves wear and tear of the spine where the facet joints - the hinge joints in the back of the spine - become arthritic and have bone spurs that then encroach upon the nerves as they exit the spine. The ultrasound examinations had been performed in tertiary and teaching hospitals using standard techniques and included both longitudinal and transverse views of the carotid bifurcation and relevant stenosis to obtain Doppler readings.

A point of care ultrasound was performed. The longitudinal view of the kidney shows mild hydronephrosis. A 6.8 mm stone is visible in the right PUJ. It is best seen in the longitudinal scan of the bladder, but visible on the transverse scan. With colour Doppler a small twinkle artefact is produced and the urinary jet is visible. Currently, most cases of PUJ obstruction are detected by pregnancy ultrasound while the baby is still in the womb.

Boys are affected with UPJ obstruction more commonly than are girls . Lesions are found more frequently on the left than on the right side. A 71-year-old woman was incidentally found to have hydronephrosis at ultrasound in 1992.

Patients with PUJ obstruction diagnosed by prenatal ultrasound should have a postnatal ultrasound. The timing of ultrasound is variable and depends on the severity of the PUJ obstruction. In general, however, ultrasound examination should be avoided in the first 2 days after birth, because hydronephrosis may not be detected because of extracellular fluid shifts that will underestimate the degree of hydronephrosis. Frequently, a PUJ obstruction will be detected incidentally on ultrasound or CT scans.

PUJ stands for 'pelvic ureteric junction'. The renal pelvis is where the urine collects, to then drain down the ureter into the bladder. Sometimes the connection between the renal pelvis and the ureter is too narrow. This is called a pelvic ureteric junction obstruction (PUJ obstruction).
