Background and Aim: Percutaneous nephrolithotomy (PCNL) was considered a safe and efficient method for removing kidney stones, with a low incidence of complications. This study aims to compare the success rate of PCNL based on guy's stone score (GSS) operating procedure and its complications. Methods: Data were collected from patients with kidney stones who underwent PCNL. A stone-free rate (SFR) was considered if the patient was either had no stone or had any stone that is <4 mm and asymptomatic residual fragment. Complications were assessed using the modified Clavien score, and SFR was assessed by abdominal radiography. Results: A total of 198 patients were included in this study. There was a significant difference in SFR between simple (GSS I and II) and complex stone (GSS III and IV) groups (P = 0.000). The operation procedure was longer in the complex group compared to the simple groups for both total operating time and stone fragmentation time (P = 0.000). X-ray time was not significantly different (P = 0.061). Almost all patients were classified as Clavien I, as there was no significant difference between the two groups for complication (P = 0.277) or blood loss (P = 0.176). Conclusion: The success rate of PCNL based on the GSS at Gunung Jati Regional Hospital is quite good. There was a difference in the SFR between the groups, and the operating procedure time was longer in the complex stone group. There was no difference between the simple stone and complex stone groups in PCNL complications, which indicated a good surgical practice.
