Pelvic ureteric junction is referred to as PUJ. This is where the ureter, the tube that connects the kidney to the bladder, connects to the renal pelvis. The filtering portion and the collecting portion make up each kidney. Urine gathers in the renal pelvis before flowing through ureter and into the bladder. The space between the renal pelvis & the ureter can occasionally be too small. The pelvic ureteric junction blockage is what this is (PUJ obstruction). Only 1 in 1500 kids will experience PUJ obstruction, making it a very uncommon condition. Although it may take some time for signs to become visible, it may be present since birth.
Less frequently, the obstruction is brought on by a blocked blood artery that crosses the renal pelvis. This kind of PUJ is frequently observed in older kids. Blood flow is impacted by the obstruction, therefore depending on how much blood is flowing through the vessel, the issue may cease and start. Pain, recurrent urinary tract infections, as well as kidney damage can all result from PUJ obstruction, yet frequently there aren’t any symptoms at all. A diagnostic ultrasonic scan is typically used. This will reveal a normal-sized ureter together with dilatation (intensification) of the renal pelvis. We also carry out a specialised test known as a MAG-3 that can demonstrate how effectively the kidney functions and drains.
