PBM Patch for Postoperative Pain Relief After Urological Surgery

June 25, 2026 updated by: National Taiwan University Hospital

A Double-blind Randomized Controlled Clinical Study of the PBM Patch for Postoperative Pain Relief After Urological Surgery

This study is a prospective, randomized, double-blind, placebo-controlled clinical study designed to evaluate the efficacy and safety of a photobiomodulation (PBM) patch (Super Vi PBM Patch - Soothing) and an enhanced PBM patch (Super Vi PBM Patch - Soothing EX), compared with a placebo patch, for postoperative pain relief following urological surgery, including nephroureterectomy with bladder cuff resection (NU+BCR) and adrenalectomy (ADRX).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Time-Weighted Mean Visual Analogue Scale (VAS) Pain Score at Rest
Time Frame: Baseline (preoperatively), and 1 hour ±30 minutes, 2±1 hours, 6±2 hours, 12±2 hours, and 24±2 hours postoperatively
The preoperative baseline VAS pain score at rest will be recorded before surgery. Postoperative VAS pain scores at rest will be assessed at 1 hour ±30 minutes, 2±1 hours, 6±2 hours, 12±2 hours, and 24±2 hours after surgery. The time-weighted mean VAS pain score at rest (Scale: 0-100 mm; higher scores indicate worse pain) during the first 24 hours postoperatively will be analyzed using a mixed model for repeated measures (MMRM). Sensitivity analysis will be performed using the area under the curve from baseline to 120 hours (AUC₀-₁₂₀h) with an analysis of covariance (ANCOVA) model.
Baseline (preoperatively), and 1 hour ±30 minutes, 2±1 hours, 6±2 hours, 12±2 hours, and 24±2 hours postoperatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Total Postoperative Analgesic Consumption
Time Frame: Up to 120 hours postoperatively
Comparison of the frequency and total dosage of analgesic use among the three groups within 120 hours postoperatively. Analgesics include non-opioids (e.g., Acetaminophen, NSAIDs) and opioids (e.g., Morphine, Tramadol). Opioid use will be converted to Morphine Milligram Equivalents (MME) for standardized comparison, in order to evaluate and verify the opioid-sparing effect of the study patch.
Up to 120 hours postoperatively
Proportion of Patients Achieving Patient Acceptable Symptom State (PASS)
Time Frame: 1 hour ±30 minutes, 2±1 hours, 6±2 hours, 12±2 hours, 24±2 hours, 48±2 hours, 72±2 hours, 96±2 hours, and 120±2 hours postoperatively
Proportion of participants in each group achieving Patient Acceptable Symptom State (PASS), defined as a Visual Analogue Scale (VAS) pain score of ≤33 mm (scale: 0-100 mm; higher scores indicate worse pain) at 1 hour ±30 minutes, 2±1 hours, 6±2 hours, 12±2 hours, 24±2 hours, 48±2 hours, 72±2 hours, 96±2 hours, and 120±2 hours postoperatively, used to assess patient satisfaction with pain control.
1 hour ±30 minutes, 2±1 hours, 6±2 hours, 12±2 hours, 24±2 hours, 48±2 hours, 72±2 hours, 96±2 hours, and 120±2 hours postoperatively
Clinical Recovery Progress
Time Frame: From end of surgery to hospital discharge, assessed up to 5 days postoperatively
Time to first ambulation out of bed and length of postoperative hospital stay will be recorded and compared among the three groups, to evaluate whether patch treatment accelerates the clinical recovery process.
From end of surgery to hospital discharge, assessed up to 5 days postoperatively
Quality of Life Improvement
Time Frame: Baseline (preoperative) to 120 hours postoperatively
Change in quality of life from preoperative baseline to 120 hours postoperatively, assessed using the Traditional Chinese version of the EQ-5D-5L questionnaire (EuroQol 5-Dimension 5-Level). Higher index scores indicate better health-related quality of life. The EQ Visual Analogue Scale (EQ-VAS) will be reported as a supplementary measure, with higher scores indicating better self-rated health.
Baseline (preoperative) to 120 hours postoperatively
Safety Assessment
Time Frame: Up to 120 hours postoperatively
Detailed recording of all adverse events occurring during the study period, including patch-site skin reactions (e.g., erythema, itching, rash) and analgesic-related side effects (e.g., nausea, vomiting, dizziness).
Up to 120 hours postoperatively
