Nephrostogram in a patient with severe left-sided hydronephrosis shows a distended urinary collecting system and ureter with distal stenosis and abrupt cutoff.
Case Discussion
Nephrostogram (antegrade pyelogram) fluoroscopically evaluates the upper collecting system by introducing water-soluble contrast through the nephrostomy catheter and can be helpful to determine tube position, and assess residual stones in the upper collecting system or the level of the urinary tract stenosis.
