Study summary

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.

Read the detailed description

Eligible participants will be screened strictly according to the inclusion and exclusion criteria and enrolled until the required sample size is reached.

At enrollment, baseline data will be collected for all participants, including: (1) basic patient information, such as age and sex; (2) a standardized 72-hour voiding diary; (3) a current medication list; (4) the Overactive Bladder Symptom Score (OABSS); (5) the Patient Perception of Bladder Condition Scale (PPBC-S); (6) the Quality of Life scale (QOL); (7) the Self-Rating Anxiety Scale (SAS); (8) the International Prostate Symptom Score (IPSS).

Eligible participants will be randomly assigned to Group A or Group B in a 1:1 ratio. Participants in Group A will receive daily behavioral therapy, while participants in Group B will receive daily behavioral therapy plus transcutaneous tibial nerve stimulation (TTNS) using the patch, three times per week, 30 minutes per session, for a total of 12 weeks.

Follow-up visits will be conducted at Weeks 1, 4, 8, and 12 after enrollment. At each follow-up visit, the following data will be collected: (1) the standardized 72-hour voiding diary; (2) the current medication list; (3) OABSS; (4) PPBC-S; (5) QOL; (6) SAS; (7) IPSS; and (8) adverse events.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

What researchers measure

Primary outcomes

  1. The frequency of daily urination over a period of three days

    Standardized 72-hour voiding diary, record the frequency of daily urination over a period of three days

    Time frame: From enrollment to the end of treatment at 12 weeks

Secondary outcomes

  1. The urgency severity、nocturia frequency and number of incontinence episodes over a period of three days

    Standardized 72-hour voiding diary, record the urgency severity、nocturia frequency and number of incontinence episodes over a period of three days

    Time frame: From enrollment to the end of treatment at 12 weeks

  2. Overactive Bladder Symptom Score (OABSS)

    The OABSS score is mainly used for initial severity grading, with total scores ranging from 0 to 15: 0-5 as mild, 6-11 as moderate, and 12-15 as severe.

    Time frame: From enrollment to the end of treatment at 12 weeks

  3. Patient Perception of Bladder Condition Scale (PPBC-S)

    The PPBC-S is a single-item, self-reported scale used to assess the patient's global perception of their bladder condition. The score ranges from 1 to 6, with higher scores indicating greater bother caused by the bladder condition. A score of 1 or 2 is generally regarded as mild, 3 or 4 as moderate, and 5 or 6 as severe.

    Time frame: From enrollment to the end of treatment at 12 weeks

  4. Quality of Life (QOL) Scale

    The QOL scale used is the International Prostate Symptom Score quality of life question (IPSS-QoL). It is a single-item, self-reported assessment that asks: "If you were to spend the rest of your life with your urinary condition just the way it is now, how would you feel about that?" The score ranges from 0 (delighted) to 6 (terrible), with higher scores indicating a poorer quality of life due to urinary symptoms. A score of 0-1 is generally considered good, 2-3 as mixed, and 4-6 as poor.

    Time frame: From enrollment to the end of treatment at 12 weeks

  5. International Prostate Symptom Score (IPSS)

    The IPSS is a validated, self-administered questionnaire used to assess the severity of lower urinary tract symptoms. It consists of seven questions covering incomplete emptying, frequency, intermittency, urgency, weak stream, straining, and nocturia. Each question is scored from 0 to 5, yielding a total score ranging from 0 to 35. Severity is graded as mild (0-7), moderate (8-19), and severe (20-35).

    Time frame: From enrollment to the end of treatment at 12 weeks

  6. Self-Rating Anxiety Scale (SAS)

    The SAS is a self-administered questionnaire designed to assess the level of anxiety in patients. It consists of 20 items, each scored on a 4-point scale (1-4) based on the frequency of symptoms over the past week. The raw total score is multiplied by 1.25 to obtain a standardized score ranging from 25 to 100. Higher scores indicate greater anxiety severity. A standardized score of 50 or above suggests clinically significant anxiety, with 50-59 classified as mild, 60-69 as moderate, and ≥70 as severe.

    Time frame: From enrollment to the end of treatment at 12 weeks

  7. Safety endpoints and the occurrence of adverse events

    including pain and infection at the stimulation site, tibial nerve injury (e.g., motor dysfunction, neuralgia), and urological complications.

    Time frame: From enrollment to the end of treatment at 12 weeks

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2026; primary completion for Jan 2027, 7 months later.

Of 98 non-industry interventional studies with no phase under Lower Urinary Tract Symptoms, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 59. This study's planned 7 months is below that.

Counting every sponsor, half of 119 studies reached it within 27 months; a quarter within 11 and three quarters within 54.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
