The ERAS method is applied to numerous urological disease treatments. However, its efficiency in PCNL (percutaneous nephrolithotripsy) is still under study. This study aims at understanding the safety, feasibility, and value of using ERAS (enhanced recovery after surgery) for PCNL.

The researchers chose patients admitted between Jan and Dec 2018 and were diagnosed with renal calculi. The subjects were either given ERAS or the traditional method. Each group contained 118 subjects, and the researchers measured the pain score, stone clearance rate, perirenal hematoma risk, extravasation of urine risk, fever, blood transfusion, and the length of stay in the hospital after surgery.

The two groups had similar stone clearance rates, cost of the treatment, and operation time. However, the pain factor was significantly lower in the ERAS group than the traditional one after four hours from the surgery. The compliance rate in the traditional group was 22 cases and 15 cases in ERAS. The hemoglobin level decrease in the ERAS group was lower than the traditional one. There was no case of impairment in organs like the intestine, spleen, gallbladder, liver, or pancreas.

The study proved that it is feasible to use ERAS in PCNL treatment without creating additional complications. It also proved the economic and convenience factors of using ERAS.
