UPJ obstruction
UPJ Obstruction is a blockage where your kidney connects to the ureter, the tube that carries urine to the bladder. This can cause urine to back up, leading to symptoms like side pain, nausea, or infection. It can be present from birth or develop later, and treatments are available to ensure proper kidney drainage and health.
