Study is done as clinical trial on 80 patients with age of minimum 18 years, in ASA class of I and II, and candidate for Trans Urethral Lithotripsy (TUL) as elective and under general anesthesia at the Velayat hospital of Qazvin from June 2017 to Feb 2018. Patients in parallel design are divided randomly (colorful cards) in two groups (A, F). 15 min before entering to operation room, A group receives 15 mg/kg intervenes Astaminiphon diluted to volume of 100 ml with Normal saline, and F group infusions 100 ml Normal saline as placebo. All patients will be placed under standard monitoring including NIBP, ECG, Puls oximetry and Oxygen saturation. Then patients receive 0.02 mg/kg Midazolam as premedication. Before Anesthesia induction, F group receives 1.5 mg/Kg intervenes Fentanyl, and A group receives 2 ml Normal saline. Patients are pre oxygenated for 3 min. For the Anesthesia induction, 2 mg/kg intervenes Propofol is prescribed. Patients are ventilated with mask and following anesthesia is done with infusion 100 micro gr/Kg Propofol and N2O- O2 gases with proportional 50-50. After conscious and also 5, 15 and 30 minutes after interring to the recovery, pain severity is evaluated via Visual Analog Scale (VAS). After interring to ward, pain severity is followed up to 24 hours after surgery, and 25 mg inter muscle Petedine is injected per 8 hours if needed (VAS˃3).50-50. After conscious and also 5, 15 and 30 minutes after interring to the recovery, pain severity is evaluated via Visual Analog Scale
