Inadvertent foley catheterization of the ureter.

We present a case of an 83-year-old woman with multiple sclerosis and chronic indwelling urethral catheter who was found to have a ureteral injury after inadvertent placement of a foley catheter into the proximal right ureter. Cystoscopy and retrograde ureteral stenting was attempted, but unsuccessful. The patient ultimately underwent successful antegrade ureteral stenting and nephrostomy placement. We review the limited literature on the topic of aberrant foley catheter placement into the ureter.
