Interstim neuromodulation is a very viable option for refractory overactive bladder symptoms: urgency, frequency and urge incontinence, as well as urinary retention that is not from obstruction.
It just got easier!
Interstim can be placed as a test lead in the office, while awake of course (and with some local anesthesia) as temporary leads. Usualy two are placed, one into each S3 foramen. The lead are superthin and are taped to the skin for easy removal once the test week is over. The leads are connected to the pulse generator box the same way.
This method averts the Stage I procedure which is done in the operating room. If testing is succcessful with the office-placed leads, the patient can skip to Stage II, that is, implantation of the permanent lead and battery generator in the operating room.
It's been around 10 years. About 2/3-3/4 of patients will respond, and can have dramatic improvement in their quality of life because the bathroom is not the main thing they worry about.
More to come. . . Chronic constipation treated with InterStim???
