Brief summary: Regional anesthesia is defined as the temporary removal of nerve conduction and pain in certain areas of the body with local anesthetic drugs without causing loss of consciousness. Spinal anesthesia can provide better analgesia and shorter recovery time in urological procedures resulted in shorter operating times, lower postoperative pain, lower analgesic requirements, and shorter length of stay (LOS) compared to the general anesthesia. Lidocaine is an attractive regional anesthesia drug for ambulatory surgery since it has a rapid onset and rapid recovery from motor and sensory block. However, when it is compared with other local anesthetic agents, the use of lidocaine in spinal anesthesia is associated with an increased risk of transient neurologic symptoms, thus impeding its application to outpatient spinal anesthesia. Lidocaine is more neurotoxic than other local anesthetic agents, especially when high concentrations are applied directly to nervous tissue. Another local anesthetic agent can be used is prilocaine. It has medium potency, rapid duration, and rapid onset of action. Compared with lidocaine, prilocaine has a lower incidence of neurological symptoms in spinal anesthesia for outpatient surgery, and suitable as an alternative to long-acting low-dose local anesthetics. Therefore, the investigators intend to observe the efficacy and safety of these two agents in adult patients who will undergo cystoscopy procedure using spinal anesthesia. In this study the investigators used high-sensitivity C-Reactive Protein (hs-CRP) and high-sensitive Troponin (hs-Troponin). CRP is a systemic inflammation marker associated with conditions such as pain. Troponin can represent patient's kidney function since its metabolism and excretion are affected by changes of estimated glomerular filtration rate (eGFR). Previous study also showed that the use of spinal anesthesia can reduce the incidence of acute kidney injury. Therefore, the investigators aim to carry out further examination of the following two markers regarding to spinal anesthesia using lidocaine and prilocaine.

Detailed description: The investigators will conduct a double-blind randomized controlled trial to compare hs-CRP and hs-Troponin levels between prilocaine 2% and hyperbaric lidocaine 5% in adult patients undergoing cystoscopy procedure with spinal anesthesia. This study was approved by the Health Research Ethics Committee (Institutional Review Board) of Dr. Moewardi General Hospital Surakarta. Before randomization, participants who are eligible based on inclusion and exclusion criteria will be given informed consent. If the patients agree, the patient will be included in this research. Ninety adult patients will be randomly divided into control group and treatment group. Control group (group L) will be given 1 mL hyperbaric lidocaine 5% (50 mg) and treatment group (group P) will be given 2.5 mL prilocaine 2% (50 mg) as spinal anesthesia. The investigators will measure hs-CRP serum levels and hs-Troponin serum levels as the primary outcome. Serum levels of hs-CRP dan hs-Troponin will be measured 4 hours postoperative.

3. Normal BMI according to WHO (World Health Organization) classification (18.5-24.9 kg/m2)
4. Physical status ASA (American Society of Anesthesiologists) I or ASA II according to the ASA Physical Status Classification System by the American Society of Anesthesiologists in 2020.
5. Do not have a history of disease, medication, and medical procedures related to coronary heart disease
6. There are no absolute contraindications for spinal anesthesia
7. Do not take non-steroidal analgesics and steroids within 2 weeks before surgery.
8. Do not have history and treatment of Diabetes Mellitus.
9. Willing to participate in research and sign informed consent

Exclusion Criteria:
