Official title

Efficacy of Nephrostomy Tract Local Anesthetic Infiltration for Postoperative Pain Control Following Prone Percutaneous Nephrolithotomy: A Prospective Randomized Controlled Trial

Overview

This prospective, randomized, controlled clinical trial aims to evaluate the effectiveness of nephrostomy tract local anesthetic infiltration for postoperative pain control in patients undergoing prone percutaneous nephrolithotomy. Eligible patients will be randomly assigned to either a control group receiving standard systemic postoperative analgesia or an intervention group receiving standard analgesia plus infiltration of 20 mL of 0.25% bupivacaine along the nephrostomy tract at the end of surgery. Postoperative pain will be assessed using the Visual Analog Scale at 1, 6, 12, and 24 hours. Secondary outcomes will include time to first analgesic requirement, total opioid consumption during the first 24 hours, need for rescue analgesia, time to mobilization, length of hospital stay, and treatment-related complications. The study is designed to determine whether nephrostomy tract infiltration provides a simple, safe, and effective adjunct for reducing pain and analgesic consumption after percutaneous nephrolithotomy.

Interventions

  • Drug Bupivacaine
    A total of 20 mL of 0.25% bupivacaine will be administered by local infiltration along the nephrostomy tract at the end of surgery. The infiltration will include the skin, subcutaneous tissue, muscular layers, and tissues surrounding the nephrostomy tract.
  • Drug Intravenous Tramadol and Paracetamol
    Standard postoperative systemic analgesia consisting of intravenous tramadol and intravenous paracetamol will be administered according to the institutional analgesia protocol. Rescue opioid analgesia will be provided when clinically required.

Primary outcome measures

  • Postoperative Pain Intensity Assessed Using the Visual Analog Scale [Time frame: At 1, 6, 12, and 24 hours after surgery]
Secondary outcome measures (3)
  • Time to First Rescue Analgesic Requirement [Time frame: From the end of surgery until the first rescue analgesic administration, within the first 24 postoperative hours]
  • Total Opioid Consumption During the First 24 Postoperative Hours [Time frame: During the first 24 hours after surgery]
  • Requirement for Rescue Analgesia [Time frame: During the first 24 hours after surgery]

Eligibility criteria

Inclusion criteria

  • Adults aged 18 to 75 years
  • Scheduled to undergo elective percutaneous nephrolithotomy in the prone position
  • Classified as American Society of Anesthesiologists physical status I-III
  • Able to understand and complete postoperative pain assessments using the Visual Analog Scale
  • Willing to participate in the study
  • Provision of written informed consent

Exclusion criteria

  • Known allergy or hypersensitivity to bupivacaine or other local anesthetic agents Coagulopathy or clinically significant bleeding disorder Chronic opioid use History of a neurological disorder that may affect pain perception or assessment Neurological or psychiatric condition preventing reliable postoperative pain assessment Active urinary tract infection or sepsis American Society of Anesthesiologists physical status IV or higher Requirement for multiple percutaneous access tracts Bilateral percutaneous nephrolithotomy Requirement for postoperative intensive care Refusal or inability to provide written informed consent
