Retrospective Analysis of Different Quadratus Lumborum Block Techniques on Recovery Quality and Analgesic Consumption in Radical Cystectomy Patients
Turkey (Türkiye)32 participantsStarted 2023-10-15
Plain-language summary
This retrospective observational study evaluates the effects of different Quadratus Lumborum Block (QLB) techniques on postoperative recovery and total opioid consumption in patients undergoing radical cystectomy under general anesthesia. The study will analyze intraoperative and postoperative patient records from October 15, 2023, to October 15, 2024, at Tekirdağ Namık Kemal University Hospital.
Patients who received anterior or posterior QLB for postoperative analgesia will be included. Data collection will involve demographic information, total opioid consumption (morphine milligram equivalents), recovery quality scores (QoR-15), postoperative pain scores (Visual Analog Scale, VAS), time to first rescue analgesic administration, frequency of rescue analgesic use, and incidence of postoperative nausea and vomiting (PONV).
The retrospective analysis will compare the two QLB techniques to determine if there is a significant difference in postoperative opioid consumption and recovery quality. Statistical methods will be used to assess pain scores over time, opioid consumption, and overall recovery quality.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
