After careful pre anaesthetic check-up and routine investigations, an informed consent will be taken from the patients. Patients will be kept fasting for more than 8 hours for solid food and 2 hours for clear fluid.

In the operation theatre, the standard monitors [electrocardiograph (ECG), pulse oximeter (SpO₂), non-invasive blood pressure (NIBP) end tidal carbon dioxide (EtCO₂)] will be attached and baseline heart rate (HR) and blood pressure (systolic, diastolic and mean) will be noted.

General anesthesia will be induced using propofol (2 mg/kg), fentanyl (2mg/kg) and atracurium followed by insertion of an appropriate size Proseal laryngeal mask airway  (PLMA). Anesthesia will be maintained with sevoflurane (2–3 vol%) in a mixture of N2O 50% and oxygen 50%; the end-tidal concentration of sevoflurane will be adjusted to maintain a target MAC of 1 and appropriate vital signs. Normal saline will be infused continuously through out the surgery to irrigate the bladder in-group N where as in group L normal saline with a lidocaine dose of 0.01% (100mg in 1L NS) will be used for irrigation 30 minutes before completion of surgery. After tumor resection urinary bladder catheterization will be done using a ≥20 Fr catheter, and the balloon will be inflated with 10 mL of distilled water. A 2% lidocaine gel will be used to lubricate the catheter, which will be fixed in the suprapubic area with adhesive tape. Appropriate antiemetic medication and paracetamol 15mg/kg will be given in end of surgery. After conforming that the patient is fully conscious and maintain adequate spontaneous ventilation the LMA will be removed and the patients will be shifted to the PACU.

Severity of CRBD symptoms will be graded as following; none (patients did not complain of CRBD when questioned); mild (reported by patients only when asked); moderate (reported by patients independently, i.e., without being asked, and not accompanied by any behavioral response); or severe (reported by patients independently along with behavioral responses such as flailing limbs, strong vocal response, and attempts to pull out the catheter).
