Bilateral obstructive uropathy following laparoscopic appendicectomy

Nathan Grimes

A fifty four year old man presented with renal failure several days following laparoscopic appendicectomy. Imaging revealed a large rectus sheath haematoma extending into the pelvis causing bilateral ureteric obstruction. The initial reason for renal failure was not clear as imaging did not reveal significant hydronephrosis as would usually be expected with ureteric obstruction, however renal function failed to improve despite addressing pre-renal causes of renal impairment. He was treated with both a retrograde ureteric stent and percutaneous nephrostomy.
