What is a low grade PUJ obstruction?

A low-grade pelvic ureteric junction (PUJ) obstruction is a mild form of blockage where the ureter meets the renal pelvis, affecting urine flow from the kidney to the bladder. This condition may lead to intermittent symptoms such as flank pain or occasional urinary issues but often does not result in severe kidney damage. Diagnosis typically involves imaging studies, and management may include monitoring or, in some cases, surgical intervention if symptoms progress. Early detection and appropriate management are crucial to prevent complications.
