Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older undergoing TUR-B who are conscious, cooperative, and able to stay at least one night postoperatively, with Turkish language ability.
✕Probably not a fit
Patients who withdraw, have complications, require ICU care after surgery, or have chronic pain may not benefit.

What this trial studies
Adults undergoing transurethral resection of the bladder will be randomized to learn and use the 4-7-8 breathing technique postoperatively to see if it improves sleep, lowers pain, and enhances recovery scores. The study uses validated scales to measure sleep, pain, and recovery, with 90% power to detect a large effect. Data collection includes consent, baseline characteristics, and follow-up assessments conducted by trained researchers. The lead site is Tarsus University in Turkey.
Why it matters
Potential benefit: If successful, the breathing technique could be a simple, non-pharmacologic method to improve postoperative comfort and recovery.
How similar studies have gone: Previous studies in breathing techniques suggest potential benefits for sleep and pain, but this specific approach after TUR-B would be relatively novel.
