A unique complication: Iatrogenic renal pelvis perforation following accidental urinary catheterisation of an intramural ectopic ureter

A 5-month-old, female, entire golden retriever presented for investigation of urinary incontinence and recent tract infection. While under general anaesthesia, a catheter was placed to fill the bladder, aid accurate visualisation ureteral vesicular junction facilitate retrograde contrast study. The preliminary computed tomography deemed unremarkable, intravenous urethrogram performed, followed by in an attempted vaginourethrogram. post-contrast study highlighted unusually straight distal right ureter escaping into retroperitoneal space. Contrast-enhanced ultrasonography supported haemorrhage perirenal space, on retrospective analysis pre-contrast sequences, identified renal pelvis. Accidental catheterisation intramural ectopic iatrogenic perforation ultimately concluded. dog made full recovery with conservative management date has no chronic repercussions injury.
