Hydronephrosis
This condition is the result of the kidneys being abnormally dilated or overfilled with urine. It can be caused by blockage along some part of the urinary tract or by abnormal backflow of urine from the bladder. It can also be due to the abnormal development or formation of the kidney.

Undescended testicles
Undescended testicles occurs when one or both testicles fail to move into the scrotum before birth. If one or both does not descend, sperm production can be impaired and there is a risk of complications.

Ureteropelvic junction obstruction
This is a blockage at the point where the kidney attaches to the tube that leads to the bladder. This blocks the flow of urine out of the kidney. UPJ obstruction mostly occurs in children and often happens when a baby is still growing in the womb.
