Ureteric Suture Urolithiasis Following Open Emergency Ureteric Repair

摘要

Suture urolithiasis is an unusual but recognised phenomenon following surgery on the urinary tract. We report a case in a 30-year-old man who sustained a gunshot injury to the left ureter in Burundi and underwent open ureteric repair in a regional hospital. He migrated to the UK and presented one year later with left loin pain. An intravenous urogram revealed two foci of calcification to the left of L3, within a peri-ureteric position. The patient underwent left-sided ure-teroscopy where two calculi each formed around a nylon suture were discovered within a ureteric pseudo-diverticulum, and basketed. This is the first reported case of suture urolithiasis occurring following ureteric surgery.
