Ureteropelvic junction (UPJ) obstruction is a blockage in the renal pelvis of your kidney, causing pee to slow or stop completely. Treatment may include surgery. Locations :

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.

2023年7月10日 · Ureteropelvic junction obstruction (UPJO) is a well-recognized clinical entity that results in impaired urine flow from the renal pelvis into the ureter and, if not detected and treated properly, can result in complete loss of the affected kidney.

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).

Ureteropelvic junction obstruction refers to a blockage at the point where the kidney meets the ureter, which impairs the flow of urine. This article will explore the condition’s risk factors, symptoms, diagnostic tests, medications, procedures, and home management strategies.

What is Ureteropelvic Junction Obstruction? Ureteropelvic junction (UPJ) obstruction is when part of the kidney is blocked. Most often it is blocked at the renal pelvis. This is where the kidney attaches to one of the ureters (the tubes that carry urine to the bladder). The blockage slows or stops the flow of urine out of the kidney.

Crossing vessels compressing or distorting the ureteropelvic junction (UPJ) may be the sole cause of ureteral outflow obstruction or may coexist with other causes of UPJ obstruction. In patients with a possible UPJ obstruction, retrograde ureteropyelography can be useful in defining the subtype of anatomic defect and in ensuring the normalcy of ...

UPJO occurs when there is blockage at the junction of the renal pelvis and the ureter. The blockage may be due to an anatomic reason, such as a blood vessel to the kidney crossing over top of the ureter at the ureteropelvic junction, or it may be due to a narrowed and nonfunctioning segment of the ureter. How does UPJ obstruction present?

5 天之前 · Ureteropelvic junction (UPJ) obstruction is a condition where the part of the kidney that normally drains urine becomes blocked. This blockage prevents the normal flow of urine out of the kidney and into the bladder, which can lead to kidney damage and swelling (called hydronephrosis ).

Ureteropelvic junction (UPJ) obstruction occurs when this connection between ureter and kidney is blocked or narrower than usual. When this occurs, urine builds up behind the obstruction. This can lead to swelling of the kidney (hydronephrosis) …
