Pelvic ureteric junction obstruction (PUJO) is a condition characterized by a blockage or narrowing at the junction where the ureter connects to the kidney pelvis, leading to impaired urine flow from the kidney to the bladder. This condition may result in various symptoms such as flank pain, recurrent urinary tract infections, kidney stones, and renal impairment if left untreated. Diagnosis typically involves imaging studies such as ultrasound, CT scan, or MRI to visualize the obstruction and assess its severity. Treatment options may include watchful waiting, medications to manage symptoms, minimally invasive procedures such as endoscopic ureterotomy or laparoscopic pyeloplasty to alleviate the obstruction, or surgical intervention in more severe cases. Early diagnosis and prompt intervention are crucial for optimal outcomes in managing pelvic ureteric junction obstruction.
