Study summary

This is a prospective series of consecutive cases of patients undergoing iTind for the treatment of male LUTS.

Read the detailed description

This is a prospective series of consecutive cases of patients undergoing iTind for the treatment of male LUTS.The procedure was carried out using perioperative antibiotic prophylaxis, according to the local culture and sensitivity profile. Patient will be discharged and readmitted 7 days for device removal under local anaesthesia transurethrally. After the device is removed and patients will be monitor for any problem in voiding or haematuria, and then discharged. Subjects will be follow-up at 3-, 6, 12- months after treatment.

Study arms

  • Experimental
    Temporarily implanted nitinol device (iTind) group

    Subjects will undergo iTind for the treatment of male LUTS.

    Device: iTind device

Interventions

  • DeviceiTind device

    Cystoscopy will be performed to assess the anatomy of the bladder and prostate. The iTind device would be inserted under visual guidance into the bladder. The device will then be deployed and under visual guidance, it will be positioned at the prostatic lumen. After confirming the position of the device, cystoscopy will be withdrawn and the position will be finished.

What researchers measure

Primary outcomes

  1. Changes in International Prostate Symptom Score (IPSS) at 6 months after treatment score

    Change in total scores in International Prostate Symptom Score (ranges from 0 to 35) questionnaires.The higher score the more worse symptom.

    Time frame: Baseline and 6 months

Secondary outcomes

  1. 30-day complications after study intervention

    The severity of AE is grade by Clavien-Dindo classification.The higher score, the more worse complication

    Time frame: at 30 days after study intervention

  2. Total score in IPSS questionnaire after study intervention

    International Prostate Symptom Score (ranges from 0 to 35) questionnaires. The higher score the more worse symptom.

    Time frame: Baseline, 3 months, 6 months and 12 months

  3. International Prostate Symptom Score (IPSS) questionnaire QoL Score

    Change in quality of life assessed by International Prostate Symptom Score questionnaire (ranges from 0 to 6). The lower score the more worse QoL

    Time frame: Baseline, 3 months, 6 months and 12 months

  4. Overactive bladder symptom score (OABSS) questionnaire total score

    Change in total score in Overactive Bladder Symptom Score questionnaire (ranges from 0 - 15). The higher score the more worse symptom

    Time frame: Baseline, 3 months, 6 months and 12 months

  5. Pain Score

    Post-treatment pain score ranges from 1 to 10. The higher score the more pain.

    Time frame: Immediately after study intervention and 1 wee after study intervention

  6. Urodynamic function assessed by uroflowmetry parameter

    Change in Maximum uroflow, post void residual

    Time frame: Baseline, 3 months, 6 months and 12 months
