A CT demonstrated bilateral renal obstruction: right secondary to two 4-mm distal ureteric stones, and left secondary to long-standing pelviureteric junction (fig. 1).
Right nephrostogram demonstrated a persistent right ureteric stricture (red arrows).

Another nephrostogram showed a persistent 4-cm-long stricture within the distal right ureter (fig. 2).
A right nephrostogram performed 6 weeks after surgery showed a free flow of urine from the kidney (red arrow) to the bladder (blue arrow).
