Background: Percutaneous Nephrolithotomy is one of the methods used to treat urinary stones which may be performed by standard or tubeless method. The aim of this study was to compare the outcome of percotaneus standard neoprolithotomy and tubeless neoprolithotomy in the treatment of renal stones. Methods: In this clinical trial, 107 kidney stone patients referred to Shahid Beheshti Hospital of Hamedan were randomly assigned to underwent percutaneous standard neoprolithotomy or tubeless neoprolithotomy. Success rates and postoperative complications were measured and compared in two groups. Results: All 107 patients who entered into the study completed the study. The mean score of postoperative pain in patients undergoing percutaneous Nephrolithotomy and tubeless technique was 1.72 ± 5.72 and 4.12 ± 2.22, respectively (P <0.001). The severity of pain, the frequency of need for opioid, and the average amount of injected opioids in tubeless method were significantly lower than the standard method (P <0.05). There was no significant difference between two surgical methods in terms of frequency of blood transfusion, the levels of hemoglobin, hematocrit and creatinine, as well as the rate of postoperative hematoma (P> 0.05). Conclusion: The results of this study showed that two methods of percotanous nephrolithotomy and tubeless techniques have similar success in treatment of urinary stones, but the severity of pain and the average amount of opioid consumed is more in standard percutaneous nephrolithotomy than in tubless method.
