Pediatrics: UPJ Obstruction
Pediatric UPJ obstruction is a blockage at the junction where a child's kidney connects to the ureter (the tube carrying urine to the bladder). This can cause urine to back up, potentially affecting kidney function. Often detected before birth or due to symptoms like pain or UTIs, it may require monitoring or surgery to relieve the obstruction and protect kidney health.
