Often requires surgery (Pyeloplasty)

Partial blockage of Ureter (tube that drains Kidney) at Bladder

Ureterovesical Junction Obstruction (UVJO)

Can be seen as Hydronephrosis and Hydroureter on Kidney Ultrasound

Often requires surgery (Reimplantation of Ureter)

Double Ureters

Ureteral Duplication

Two tubes drain the kidney on one side

Tubes may insert wrongly causing blockage or backup of urine

Balloon in bladder

Ureterocele
