This study aims to determine whether a standardized, weight-based crystalloid fluid bolus administered preoperatively reduces the incidence of postinduction hypotension (PIH) in patients undergoing cystoscopy.

Past history of amputations of any body part. 3. Allergies or contraindications to any medications used in the protocol or lactated ringers. 4. Systolic heart failure with LVEF \< 30% within the last year. 5. Severely depressed RV function within the last year. 6. Restrictive diastolic dysfunction within the last year. 7. Currently pregnant.
A bolus of Lactated Ringers (15mL/kg of ideal body weight) will be given to patients prior to anesthesia induction.
