Back pain after catheterization could indicate which complication?

• A. Retroperitoneal bleeding
• B. Urinary tract infection
• C. Kidney stones
• D. Appendicitis

Answer: (A)

Back pain after catheterization points to retroperitoneal bleeding from an arterial puncture during access. The retroperitoneal space can accumulate blood without obvious external signs, so the patient may develop back or flank pain that persists or worsens as bleeding continues. This situation is a medical emergency because ongoing blood loss can lead to hypotension and shock, even if you don’t see a large groin hematoma right away. Urinary tract infection would create urinary symptoms like dysuria, frequency, urgency, or suprapubic tenderness, not specifically tied to catheterization. Kidney stones typically cause sudden, severe flank or groin pain that is colicky and often accompanied by hematuria, but not linked to the catheterization event. Appendicitis presents with periumbilical pain migrating to the right lower quadrant, plus possible fever and anorexia, not related to catheterization. So if back pain follows catheterization, retroperitoneal bleeding is the most plausible and urgent explanation to consider.
