Contemporary management of the obstructed ureteropelvic junction (UPJ) in the adult has evolved. While open surgical intervention was once considered the standard of care, today there are a myriad of minimally invasive treatments to alleviate obstruction of a hydronephrotic, poorly draining kidney.Cited by: 22. UPJ obstruction occurs most often in children and prevents the proper flow of urine, thereby threatening the integrity of the kidney. UPJ obstruction can also occur in adults. In children, UPJ obstruction is often present at birth and may be due to narrowing of the proximal ureter or the presence of an abnormal blood vessel over the ureter.
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. Urine can then build up and damage the kidney. UPJ Obstruction in Adults. Uteropelvic junction (UPJ) obstruction is a blockage in the upper end of the ureter at the point where the ureter joins the renal pelvis — the ureteropelvic junction (UPJ). This condition can result in pain in one side of the body between the upper abdomen and the back or a urinary tract infection. UPJ is generally.
What is ureteropelvic junction (UPJ) obstruction? Ureteropelvic junction (UPJ) obstruction is a blockage in the renal pelvis of the kidney. The renal pelvis is located at the upper end of each ureter (tube that drains urine from the kidneys to the bladder). The renal pelvis, which is shaped like a funnel, collects urine. Ureteropelvic junction (UPJ) obstruction occurs when the area connecting the renal pelvis (part of the kidney) to one of two tubes that connect with the bladder (ureter) becomes blocked, causing urine to build up, which damages the kidneys.
