2025年3月3日 · Ureteropelvic junction (UPJ) obstruction or pelviureteric junction (PUJ) obstruction partially obstructs the passage of urine from the renal pelvis to the ureter. It is the most frequent cause of hydronephrosis in the fetus and can also present in adulthood.

The PUJ is a region of gradual transition from the funnel-shaped renal pelvis to the proximal ureter (Fig. 1). It is a physiologic sphincter [ 16 ] that is characterised by prominent luminal folds with increased muscle thickness capable of creating a high-pressure zone to regulate urine flow.

Pelviureteric junction (PUJ) obstruction is a common urological disorder with an incidence of 1 in 1000 to 1500 live births; however, the incidence is not well-defined in adults. [1–3] Congenital causes are common, and PUJ obstruction (PUJO) accounts for 5% of …

A non-dismembered foley V-Y plasty is classically described for a high insertion PUJ. It has been described in secondary PUJO and can be utilized in a retroperitoneal approach. Presence of a crossing vessel, need to reduce the renal pelvis size and a proximal ureteric stricture are relative contraindications to its use in a primary or secondary ...

Objective: To assess the diagnosis of children with coexisting pelvi-ureteric junction (PUJ) and vesico-ureteric junction (VUJ) obstruction, and the management of such patients, as having these two anomalies in the same ureter creates serious diagnostic difficulties, but any delay in diagnosis might cause a deterioration of renal function and ...

2014年1月1日 · Pelviureteric junction obstruction (PUJ) is one of the most common congenital abnormalities of the urinary tract. It is defined as an obstruction at the junction of the renal pelvis and proximal ureter.

Hydronephrosis (PUJ) This section discusses about blockage caused by PUJ obstruction. In this condition there is a blockage of urine at the junction of kidney and the pipe draining (ureter) – pelvi ureteric junction (PUJ).

Pelvi-ureteric junction obstruction (PUJO) is defined as a functionally significant impairment of the flow of urine from the kidney's renal pelvis into the proximal ureter. Symptomatically, the patient may experience flank pain, recurrent infections, stone formation, and impairment of renal function …

2023年8月1日 · Pelvi-ureteric junction (PUJ) obstruction is a condition where there is a blockage at the point where the renal pelvis (the area where the kidney collects urine) meets the ureter (the tube that carries urine from the kidney to the bladder).

The PUJ is the point at which the renal pelvis joins the ureter. What is a PUJ obstruction? A PUJ obstruction is where there is an obstruction to normal urine flow from the renal pelvis into the ureter. It may be classified as either: Congenital/primary – essentially present since birth as a developmental abnormality.
