An interventional study of ropivacaine (local infiltration) and ropivacaine in Renal Cell Carcinoma (Kidney Cancer), Postoperative Pain and Nerve Block, sponsored by Huazhong University of Science and Technology. Recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-09-25.
Sponsored by Huazhong University of Science and Technology · Not applicable, Interventional, and Treatment
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:
Participants will:
2,037 studies on the registry are indexed under Carcinoma, Renal Cell; 395 are open to participants now.
This study's planned enrollment of 120 is above the median of 43 across 1,564 interventional studies indexed under Carcinoma, Renal Cell.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Participants receive ultrasound-guided QLESP block with 30 mL of 0.375% ropivacaine (15 mL in the erector spinae fascial plane and 15 mL in the quadratus lumborum-psoas major interfascial plane) after induction of general anesthesia.
Drug: ropivacaine
Participants receive local wound infiltration with 30 mL of 0.375% ropivacaine at the port sites performed by the surgeon at the end of surgery.
Drug: ropivacaine (local infiltration)
Ultrasound-guided QLESP block with 30 mL of 0.375% ropivacaine (15 mL injected between the erector spinae muscle and the transverse process at L2 level, followed by 15 mL injected between the quadratus lumborum and psoas major muscles) after induction of general anesthesia.
Local wound infiltration with 30 mL of 0.375% ropivacaine at the port sites performed by the surgeon at the end of surgery.
Cumulative Opioid Consumption at 48 Hours Postoperatively
Cumulative opioid consumption measured at 48 hours after surgery
Time frame: From the end of surgery to 48 hours postoperatively.
Plan to share: No — The study protocol and informed consent form did not include provisions for secondary data analysis by external researchers.
Started Sep 2026 (actual). Primary completion is estimated for Feb 2027, 5 months after the start.
Of 119 non-industry interventional studies with no phase under Carcinoma, Renal Cell, half reached primary completion within 48 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 114. This study's planned 5 months is below that.
Counting every sponsor, half of 126 studies reached it within 45 months; a quarter within 22 and three quarters within 114.
Start moved once since we started tracking on Sep 25, 2026: Jul 2026 → Sep 2026, on Sep 25, 2026.
