Ureteropelvic junction obstruction (UPJO) is a common congenital abnormality that often presents in adulthood. 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 is where the kidney attaches to one of the ureters (the tubes that carry urine to the bladder). This version of UPJ is usually caused by a congenital condition that was too mild to be detected during fetal or newborn development; it can also stem from a blood vessel that crosses the ureteropelvic junction, causing . There are multiple possible causes, which can be . Clinical signs of UPJO include flank pain, renal colic and infection; and may result in progressive loss of renal function (1). The resultant back pressure within the renal pelvis may lead to progressive renal damage and deterioration. Dismembered Anderson-Hynes pyeloplasty is a successful treatment for ureteropelvic junction (UPJ) obstruction with success rates as high as 98%. Most of the time, open (invasive) surgery is performed in infants. A child with a partial UPJ obstruction and a well-functioning kidney with the partial obstruction can often be treated just with observation. Untreated UPJO may cause hydronephrosis, chronic infection or urolithiasis and will often result in A pyeloplasty is a surgical procedure that is indicated for a pelviureteric junction (PUJ) obstruction. Ureteropelvic junction (UPJ) obstruction is when part of the kidney is blocked. UPJ obstruction is thought to result from abnormal smooth muscle and connective tissue development at the level of the UPJ, possibly from a reduction in nerve growth factors, malrotation of the kidney, aberrant insertion of the ureter into the renal pelvis, or, more likely in adults, extrinsic compression on the UPJ from vasculature or tumors.

Indications for treating ureteropelvic junction obstruction include: Decline in renal function seen on renogram in the pediatric population. Ureteropelvic junction (UPJ) obstruction is caused when the connection between the ureter and the renal pelvis of the kidney (ureteropelvic junction) is blocked—or narrower than normal—and urine builds up behind the obstruction. Definitive treatment is initiated with the finding of reduced or worsening renal function, worsening hydronephrosis, or both. Although the success rate is more than 80% [1], the reasons underlying persistent hydronephrosis after pyeloplasty and its management remain controversial. UPJ can also occur in adults, though not as often as in children. Obstructing calculus immediately distal to PUJ. Kidneys with UPJ obstructions are at increased risk for infection and kidney stones.

Ureteropelvic Junction Obstruction One of the most common conditions affecting the kidneys is urinary obstruction. Widespread use of antenatal ultrasonography and the advent of modern imaging techniques have resulted in earlier and more common diagnosis of hydronephrosis. This condition can result in pain in one side of the body between the upper abdomen and the back or a urinary tract infection. It is therefore important to This obstruction can lead to an increase in back-pressure on the kidney, hydronephrosis, and progressive damage to the kidney function.
