The vital signs and electrocardiogram were recorded during the patient’s stay in the operating room using the Vital Recorder (version 1.8.19.5; The primary outcome measure was ΔSBP, defined as the maximum increase in SBP during bladder hydrodistention from baseline (measured 5 min after the induction of anaesthesia). The secondary outcome measures were the maximum increase in MBP, diastolic blood pressure (DBP), and HR during bladder hydrodistention from baseline. Standard heart rate variability (HRV) measuresThe recorded cystoscopic descriptions included Hunner’s lesions, bleeding patterns, and the maximal bladder volume. Postoperative pain scores were evaluated in the post-anaesthesia care unit (PACU) based on a numeric rating scale (NRS), with 0 reflecting “no pain” and 10 “the worst pain imaginable.” If the patient complained of pain in the PACU, 25 µg of fentanyl was administered intravenously. The number of patients who required analgesics in the PACU was also recorded.
