Study summary

Overactive bladder (OAB) is a syndrome with urgency as the main symptom, usually accompanied by frequent urination, nocturia, and sometimes urge urinary incontinence. Globally, the prevalence of OAB in the general population has been reported to be about 20%. Nocturia was defined as the patient waking up at least once during the night to urinate. Among lower urinary tract symptoms, nocturia can significantly affect daily life and quality of life. Reported causes of nocturia include nocturnal polyuria, sleep disorders, circadian rhythm disruption (e.g., circadian rhythm sleep disorders), and reduced bladder capacity. Because overactive bladder (OAB) may be associated with reduced bladder capacity, anticholinergic agents are used as standard therapy in the management of nocturia associated with OAB. However, anticholinergic medications are associated with poor adherence, such as inadequate efficacy and adverse effects (e.g., dry mouth, constipation, and cognitive impairment). Therefore, it is imperative to find alternative therapies for anticholinergic drugs.

Previous studies have shown that transcutaneous tibial nerve stimulation (TNS) can also significantly improve lower urinary tract symptoms, such as frequency, urgency, incontinence, and nocturia, and is also one of the options for the treatment of OAB. A previous study also demonstrated its improvement in sleep quality in women with nocturia. However, the efficacy of tibial nerve stimulation in the treatment of active bladder with nocturia is still a blank, and further studies are needed.

Read the detailed description

In strict accordance with the inclusion criteria and exclusion criteria, appropriate research participants were screened to participate in this clinical study. At least 80 cases were completed, with 40 cases in the experimental group and 40 cases in the control group.

Participants in group A were treated with A new wearable transcutaneous tibial nerve stimulation (TTNS) device combined with behavioral therapy (BT), while participants in group B were treated with behavioral therapy alone. Participants were followed up at 4, 8, and 12 weeks after enrollment. The improvement of voiding symptoms (frequent urination, urgency, urge incontinence, etc.) and sleep quality were analyzed at different stages.

Treatment assignments: Group A, participants received tibial nerve stimulation three times a week (30 minutes each time) in combination with daily behavioral therapy. Group B: The study participants received daily behavioral therapy, and the improvement of symptoms was observed in the study participants at all stages.

Baseline data of all participants were collected at the time of enrollment: (1) basic information of patients, including age, gender, height, weight, history of smoking and alcohol, lower urinary tract dysfunction symptoms, previous treatment of OAB and nocturia, and medication history; (2) Pittsburgh sleep Quality index (PSQI); (3) standardized 72-hour voiding diary, sleep onset and awakening time, voiding volume and time, fluid intake and time, and incontinence time; (4) previous treatment of OAB and nocturia, and list of current drugs; (5) Overactive bladder symptom score (OABSS); (6) Nocturia quality of life (NQOL) score.

Study participants were followed up or reexamined at 4, 8, and 12 weeks after enrollment. Data on: (1) Pittsburgh sleep Quality Index (PSQI); (2) Standardized 72-hour voiding diary, sleep onset and awakening time, voiding volume and time, fluid intake and time, and incontinence time; (3) list of currently used drugs; (4) Overactive bladder symptom score (OABSS); (5) Nocturia quality of life (NQOL) score; (6) Urinary tract infection and adverse events.

Inclusion criteria

  1. age ≥20 years old, ≤80 years old, female;
  2. patients with overactive bladder (OAB) symptoms for more than 8 weeks; The inclusion criteria were as follows: voiding frequency ≥8 times in 24 hours, urgency attack ≥1 time in 24 hours, nocturnal voiding ≥2 times (OABSS score ≥6 points), and nocturnal polyuria index (NPi) ≤0.33.
  3. the patient's physical condition is stable and can be treated at home;
  4. All participants volunteered to participate in the study and provided written before the study began.

Exclusion criteria

Exclusion Criteria:

  1. Residual urine volume ≥100 mL;
  2. difficulty walking;
  3. urethral stricture;
  4. bladder stones;
  5. bladder cancer;
  6. urinary tract infection;
  7. pregnant, lactating women, women of childbearing age who plan to become pregnant during the study or who do not use safe ;
  8. pelvic organ prolapse;
  9. neuropsychiatric disorders (including cerebrovascular diseases) associated with neurogenic bladder;
  10. taking medications for urinary system diseases within 2 weeks before enrollment;
  11. patients with mental and cognitive impairment who are unable to cooperate with treatment;
  12. other conditions considered by the investigator to be inappropriate for study participation.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

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.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Standardized 72-hour voiding diary

    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

  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

Secondary outcomes

  1. Pittsburgh Sleep Quality Index (PSQI)

    PSQI is a self-rating scale that assesses subjective sleep quality, sleep latency, sleep time, sleep efficiency, sleep disorders, sleep medication use, and daytime dysfunction. The scale is divided into two parts: 19 self-rated questions to assess sleep and 5 questions that are assessed by a bed partner (those who do not have a bed partner but have family members who know can also answer). The questions are short, easy to understand, and easy to answer. PSQI questions are scored on a scale ranging from "0 = no difficulty" to "3 = very difficult", resulting in scores that correspond to the various domains of the scale. Scores range from 0 to 21, with scores greater than 5 considered to indicate a sleep disorder

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

  2. Nocturia quality of life (NQOL) score

    The questionnaire included 3 dimensions and 13 items. Sleep/energy (7 items, 0-28 Scores), distress/concern component (5 questions, 0-20 points) and total quality of life score (1 question, 0-4 points). Each item was selected from "0" to "4" points using Likert5 scale, with a total score of 52 points. Items 12 and 13 are reverse scoring items, with higher scores indicating higher quality of life.

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