In short
This article discusses a clinical trial investigating the use of spinal analgesia with morphine and bupivacaine in patients undergoing robot-assisted laparoscopic upper urinary tract surgery. The study aims to evaluate the effects of this approach on postoperative recovery, pain management, and other important outcomes. The trial, known as SMILe (Spinal Morphine or Intravenous Lidocaine), compares the effectiveness of spinal analgesia to standard general anesthesia in improving patient recovery and overall surgical experience.

Introduction
A clinical trial is being conducted to study the effects of intrathecal morphine in patients undergoing robot-assisted upper urologic surgery. This article aims to provide patients with a clear understanding of the treatment and its potential benefits.
What is Intrathecal Morphine?
Intrathecal morphine is a form of pain medication that is injected directly into the fluid surrounding the spinal cord. The medication used in this study is an extract of fresh opium poppy, specifically prepared with ethanol. It is administered in small doses (up to 0.3 mg) to provide pain relief during and after surgery.
Medical Conditions Treated
The study focuses on patients undergoing surgery for various urological conditions, including:
- Renal or ureter malignancy: Cancerous growths in the kidney or ureter
- Renal or ureter benign tumor: Non-cancerous growths in the kidney or ureter
- Nephrolithiasis: Kidney stones
- Renal reflux: A condition where urine flows backward from the bladder to the kidneys
These conditions may require robot-assisted laparoscopic surgery of the upper urinary tract.
Study Objectives
The main goal of this study is to determine if adding spinal analgesia (pain relief) with bupivacaine and morphine to general anesthesia can improve recovery after robot-assisted laparoscopic upper urinary tract surgery. Researchers will measure this improvement using a patient-centered outcome scale called "Quality of Recovery 15" (QoR-15).
Secondary objectives include investigating whether this approach results in:
- Less pain
- Faster mobilization (ability to move around)
- Shorter hospital stays
- Fewer complications
- Effects on intraoperative (during surgery) blood pressure and heart function
- Changes in inflammatory markers in the body
Eligibility Criteria
To participate in this study, patients must meet certain criteria:
Inclusion Criteria:
- Scheduled for elective robot-assisted upper urinary tract surgery at a participating hospital
- Able to provide informed consent after receiving information about the study
Exclusion Criteria:
- ASA-class IV or above (a measure of overall health status)
- Minors or those declared incompetent
- Severe psychiatric disease
- Inability to understand study information due to vision, hearing, or language barriers
- Pregnancy or lactation
- Emergency surgery
- Contraindications to spinal analgesia (e.g., severe blood clotting disorders, severe aortic stenosis, previous back surgery with rods)
- Contraindications to lidocaine infusion (e.g., allergy to local anesthetics, severe kidney or liver failure, severe heart problems)
These criteria ensure the safety of participants and the reliability of the study results.
Potential Benefits
The use of intrathecal morphine in this study may offer several potential benefits for patients:
- Improved overall recovery after surgery
- Better pain management
- Faster return to normal activities
- Reduced need for other pain medications
- Shorter hospital stays
- Fewer postoperative complications
However, it's important to note that these benefits are not guaranteed and are being studied as part of the clinical trial.
Possible Side Effects
While intrathecal morphine can provide effective pain relief, it may also cause side effects. Some potential side effects being monitored in this study include:
- Pruritus: Itching of the skin
- Nausea and vomiting
- Respiratory depression: Slowed breathing rate, which in severe cases may require treatment with a medication to reverse the effects of morphine
- Changes in blood pressure during surgery
The study closely monitors patients for these and other potential side effects to ensure participant safety.
Conclusion
This clinical trial aims to improve pain management and overall recovery for patients undergoing robot-assisted upper urologic surgery. By studying the effects of intrathecal morphine, researchers hope to enhance patient care and outcomes. If you're considering participating in this study, discuss the potential benefits and risks with your healthcare provider to make an informed decision.
