Spinal Anesthesia For Shock Wave Lithotripsy; Which Cases Is It Preferred In?

In this study we evaluated the efficiency and reliability of spinal anesthesia during extracorporeal shock wave lithotripsy (SWL) after the ineffective ureteroscopic lithotripsy (URL). In our clinic for 4 years, all of 17 patients who were applied SWL under spinal anesthesia (Group 1) were received to study. Also, 17 patients were administered sedo-analgesia with midazolam and fentanyl (Group 2) were included randomly into the study. Group 1 patients were transported to the SWL unit with monitoring and observance of anesthetist under spinal block after ineffective URL. The diameter of the stones, the level of the maximal energy, SWL, fluoroscopy and recovery times, the rate of stone free were recorded. The pain assessment was performed with verbal pain scale (VPS). Any patients showed hypotension, bradycardia, desaturation and nause-vomiting. There were no significant differences related to the diameter of the stones, SWL and flouroscopy times, the rate of stone free between groups. The maximal energy was 56.7 mjoule in Group 1, 47.6 mjoule in Group 2 (p
