Iatrogenic ureteral injury due to lumbar sympathetic block.

Lumbar sympathetic block (LSB) is used in the management of sympathetically maintained pain states. Complications of LSB include infection, injury of spinal cord or somatic nerve, kidney trauma, hypotension, paraplegia and genitofemoral neuralgia. This report presents the case of a 53-year-old woman who had undergone LSB for relief of reflex sympathetic dystrophy and subsequently disrupted right proximal ureter. She was treated with ureteroureterostomy and indwelling ureteral stent.
