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

実験的:Nephrostomy Tract Bupivacaine Infiltration
Participants in this arm will receive standard postoperative systemic analgesia. In addition, at the end of percutaneous nephrolithotomy, 20 mL of 0.25% bupivacaine will be infiltrated along the nephrostomy tract, including the skin, subcutaneous tissue, muscular layers, and tissues surrounding the nephrostomy tract. |
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.

Postoperative Pain Intensity Assessed Using the Visual Analog Scale
時間枠:At 1, 6, 12, and 24 hours after surgery
|
Postoperative pain intensity will be assessed using the Visual Analog Scale (VAS). Patients will rate their pain on a scale from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. VAS scores will be compared between the nephrostomy tract bupivacaine infiltration group and the standard systemic analgesia group. |

Time to First Rescue Analgesic Requirement
時間枠:From the end of surgery until the first rescue analgesic administration, within the first 24 postoperative hours
|
The time from the end of surgery to the first administration of rescue analgesic medication will be recorded in minutes. A longer duration indicates a prolonged postoperative analgesic effect. |
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
時間枠:During the first 24 hours after surgery
|
The total amount of opioid analgesics administered during the first 24 hours after surgery will be recorded. When different opioid agents are used, doses will be converted to intravenous morphine milligram equivalents for comparison between groups. |
During the first 24 hours after surgery

Requirement for Rescue Analgesia
時間枠:During the first 24 hours after surgery
|
The number and proportion of participants requiring at least one dose of rescue analgesic medication will be compared between the study groups. |
