Incontinence and overactive bladder symptoms such as urinary urgency, urinary frequency, and incontinence can be treated with urgent PC as an outpatient procedure. PTNS (percutaneous tibial nerve stimulation) is a specific type of neuromodulation delivered by Urgent PC. A small, slim needle electrode is inserted near your ankle during treatment. A battery-powered stimulator is then connected to the needle electrode. The stimulator sends mild impulses through the needle electrode, along your leg, and to the nerves in your pelvis that control your bladder and bowel functions. Neuromodulation is another name for this process.
