Noninvasive Electrical Stimulator as a Pain Control Treatment Post-ureteroscopy

The investigators will assess the use of Transcutaneous Neurostimulation (TENS), a pharmacological alternative, for treatment of ureteral stent pain post-ureteroscopy. The primary aim for the investigators is to determine if use of a TENS unit will reduce post-operative pain and nausea associated with the ureteral stent. Secondary aim will be to assess if it can help minimize narcotic use.

Stanford is currently accepting patients for this trial.
