COMPLICATIONS OF MINIMALLY INVASIVE PERCUTANEOUS NEPHROLITHOTOMY IN THE TREATMENT OF KIDNEY STONES AT MILITARY HOSPITAL 103

Abstract

Objectives: To evaluate the complications of the minimally invasive percutaneous nephrolithotomy (mini-PCNL) in treating kidney stones at Military Hospital 103. Methods: A prospective, longitudinal study on 286 kidney stone patients operated using the mini-PCNL technique at Military Hospital 103 from July 2017 to July 2019. Results: After mini-PCNL, most patients had no complication (77.62%). Bleeding and fever after mini-PCNL were the two most common complications; there were 35 patients with intraoperative bleeding and no need for blood transfusion (12.24%) and 15 patients with fever after surgery and no chills (5.24%). The stone size affected its clearance rate but did not affect fever and bleeding after mini-PCNL. After mini-PCNL, the mean values of Red Blood Cell (RBC), Hemoglobin (HGB), and Hematocrit (HCT) decreased from 4.75 ± 0.53 T/L, 140.38 ± 15.38 g/L, and 0.42 ± 0.04 L/L to 4.25 ± 0.44 T/L, 125.05 ± 13.36 g/L, and 0.38 ± 0.04 L/L, respectively. Conclusion: After mini-PCNL, the complication rate was 22.38%. Bleeding and fever after mini-PCNL were the two most common complications, with 46 patients (16.08%) and 18 patients (6.29%), respectively. The residual stone fragments were 19.58%. The stone size affected its clearance rate but did not affect fever and bleeding after mini-PCNL
