Nephrostogram

Case contributed by Dr MT Niknejad

Presentation

Left flank pain because of severe hydroureteronephrosis that reported at ultrasound evaluation.

Patient Data

Age: 50 years
Gender: Male
Fluoroscopy

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.
