Abstract

Objective: To investigate factors associated with complication rates following mini-percutaneous nephrolithotomy for kidney stones, classified by the Clavien–Dindo system, at Xanh Pon Hospital from 2023 to 2024. Methods: A cross-sectional descriptive study was conducted on 830 patients with kidney stones treated by mini-percutaneous nephrolithotomy at Xanh Pon Hospital. Early postoperative complication rates and associated factors were assessed. Results: The mean age was 50.6 ± 6.9 years; the male-to-female ratio was 65.3% male and 34.7% female. The mean BMI was 29.2 ± 8.5. The average stone size on CT was 24.5 ± 9.8 mm. Stone count distribution was as follows: 27.8% had a single stone, 11.3% had two stones, and 60.8% had three or more stones. Stone locations were 50.7% in the renal pelvis, 9.6% in the lower calyx, 13.5% in the upper calyx, 21.7% in multiple locations, and 4.5% as staghorn stones. Degree of hydronephrosis was classified as no dilation in 86.3%, grade I in 5.8%, grade II in 6.0%, and grade III in 1.9%. According to the Clavien–Dindo classification, 95.4% (792/830) of patients experienced no complications, 2.7% had grade I complications, 1.7% had grade II complications, and two patients (0.2%) had grade III complications. No correlation was found between complication rates and BMI, stone count, stone size, or stone location. Conclusions: Mini-percutaneous nephrolithotomy is a minimally invasive procedure with a low rate of early postoperative complications, most of which are mild. Factors such as BMI, stone count, stone size, and stone location were not associated with the incidence of postoperative complications.
