QLESP Block for Pain Control in Robotic Partial Nephrectomy
Ultrasound-Guided L2 Level QLESP Block for Postoperative Analgesia in Robot-Assisted Partial Nephrectomy: A Prospective Randomized Controlled Trial
Source: ClinicalTrials.gov · Last updated 25 Sept 2026
Brief summary (registry, in English)
The goal of this clinical trial is to learn if an ultrasound-guided nerve block called QLESP works to reduce pain and the need for strong pain medicines after robotic kidney surgery in adults. The main questions it aims to answer are: 1. Does QLESP reduce the total amount of opioid pain medicine participants need in the first 48 hours after surgery? 2. Does QLESP lower pain scores and improve recovery quality after surgery? Researchers will compare participants who receive QLESP block to participants who receive the same numbing medicine injected only at the surgical wound sites. Participants will: 1. Be randomly assigned to receive either QLESP or local wound injection before surgery. 2. Have a patient-controlled pain pump for 48 hours after surgery. 3. Complete pain scores and recovery quality questionnaires at 2, 6, 12, 24, 48, and 72 hours after surgery. 4. Be followed until hospital discharge.
