Renal pelvicalyceal rupture secondary to extraperitoneal pelvic packing (EPP) in the unstable trauma patient.

Presented here is the case of an 86-year-old man who was found to have right-sided pelvicalyceal rupture and anuric renal failure, secondary to obstructive uropathy caused by life-saving extraperitoneal pelvic packing (EPP) in the settling of severe trauma. In efforts to control haemorrhage in this haemodynamically unstable patient, EPP placement deviated from the recognised method of three extraperitoneal packs bilaterally with seven surgical packs placed. Progress postoperative imaging revealed right-sided hydroureteronephrosis with obstruction evident at the level of the extraperitoneal pelvic packs, identified by delayed contrast excretion from the preceding CT angiography imaging. Urology performed bilateral retrograde pyelograms at his relook laparotomy, timed after removal of his extraperitoneal packs and haemostasis, which showed impression of the surgical pack on the distal ureter but no persisting obstruction or short-term complications. Anuric renal failure improved, and renal function returned to near premorbid levels on day 4 postoperatively.
