IR Juniors GENITOURINARY INTERVENTIONS IRBITES WHAT IS IT? Obstruction of the ureters can occur due to a variety of reasons including stones, tumours & fibrosis. The increased back pressure from the accumulation of urine can lead to hydronephrosis and impaired renal function. A nephrostomy can relieve this pressure, and more rarely also be used in managing urinary tract leakage after abdominal trauma or iatrogenic injury (due to damage to the ureter).
