Trial summary

Percutaneous nephrolithotomy (PCNL) is a safe and effective procedure that is considered the standard treatment for large and complex renal stones. Although it has lower complication and morbidity rates than open surgery, the pain and discomfort related to a nephrostomy tube can cause distress for patients. Read more about this study

About this study

Official title: The Comparison of Low Thoracic Paravertebral Block Versus Peritubal Infiltration in Patients Undergoing Percutaneous Nephrolithotomy

Percutaneous nephrolithotomy (PCNL) is a safe and effective procedure that is considered the standard treatment for large and complex renal stones. Although it has lower complication and morbidity rates than open surgery, the pain and discomfort related to a nephrostomy tube can cause distress for patients.

Managing this pain with opioids can lead to sedation, nausea, vomiting, and constipation, which defeat the purpose of this minimally invasive procedure.

Skin infiltration with bupivacaine around the nephrostomy tube is not effective. Infiltration of renal capsule has shown to facilitate painless insertion of nephrostomy tube, suggesting the role of renal capsule in pain management.

Peritubal infiltration of bupivacaine from renal capsule to the skin along the nephrostomy tract may alleviate postoperative pain. A unilateral Low thoracic paravertebral (PVB) block offers the option of providing extendable perioperative pain relief without the above side effects or the physiologic derangement associated with local anesthetics in the central neuraxial space.

The aim of this study is to determine whether ultrasound guided low thoracic paravertebral block effective post-operative analgesia as compared to peritubal infiltration analgesia in patients undergoing percutaneous nephrolithotomy.

Main outcome measures: The primary endpoint is postoperative opioid consumption. Secondary endpoints are visual analogue pain scores, opioid related side effects.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Opioid consumption

    Measured: First 24 hours total opioid consumption

Secondary outcomes (6)
  1. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at first hour postoperatively.

    Measured: postoperative first hour

  2. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at second hour postoperatively.

    Measured: postoperative second hour

  3. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at 4th hour postoperatively

    Measured: postoperative 4th hour

  4. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS) score of 0-10 (0= no pain and 10= worst imaginable pain) at 8th hour postoperatively

    Measured: postoperative 8th hour

  5. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS)score of 0-10 (0= no pain and 10= worst imaginable pain) at 12th hour postoperatively.

    Measured: postoperative 12th hour

  6. Visual analog pain score

    Post operative pain will be evaluated with a Visual Analogue Scale (VAS)score of 0-10 (0= no pain and 10= worst imaginable pain) at 24th hour postoperatively

    Measured: postoperative 24th hour

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Bupivacaine and Ultrasound in people with Percutaneous Nephrolithotomy, run by Ataturk University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Opioid consumption (time frame: First 24 hours total opioid consumption). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02764008, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2016.
