The incidence of lower urinary tract symptoms (LUTS) with persistent overactive bladder (OAB) symptoms after benign prostatic hyperplasia (BPH) surgery ranges from approximately 5% to 35%, meaning that roughly one-third of patients remain troubled by symptoms such as urinary frequency, urgency, and increased nocturia following surgery.Current treatment options are limited. Although behavioral therapy (BT) is recommended as first-line treatment, patient compliance is often poor. Pharmacotherapy is associated with insufficient efficacy and adverse effects such as dry mouth, constipation, and cognitive impairment, which lead to low long-term medication adherence.
Transcutaneous tibial nerve stimulation (TTNS) has been proven effective in improving OAB symptoms and is recommended by multiple guidelines as one of the optional treatment modalities. However, research on its application in patients after BPH surgery remains lacking.The novel transcutaneous tibial nerve stimulation patch device offers the advantages of being non-invasive, portable, and suitable for home-based treatment. Whether combining this device with behavioral therapy can provide additional benefits for patients with refractory lower urinary tract symptoms after surgery needs to be verified through clinical research. Therefore, we plan to conduct this randomized controlled study to evaluate the efficacy and safety of the transcutaneous tibial nerve stimulation patch combined with behavioral therapy.
