In most cases, sacral neuromodulation is used as a treatment for urge incontinence and symptoms of urgency and frequency. It is most used in those who are refractory to traditional management. It is much less common to be used for bladder atony. In this report, we present a case of a 24-year-old woman with a history of urinary retention and bladder atony who failed medical management and subsequently had an InterStim sacral neuromodulator implanted. After implantation, she was able to discontinue intermittent catheterization and had a decrease in her postvoid residual from 848 to 72 mL.
