Abstract

Objective: The aim of this study is to evaluate the treatment result of staghorn stones by mini percutaneous nephrolithotomy at the Hospital of Post and Telecommunications. Subject and method: This is a descriptive study of 85 patients with staghorn stones treated by the mini-percutaneous nephrolithotipsy at the Hospital of Post and Telecommunications from period of June 2022 to June 2023. Result: We studied 85 patients whose average age was 54,6 ± 9,5 with the mean size of stones be 37,2 ± 7,2 mm. There was 65,9% of 85 patients to have more than one staghorn kidney stone and 34,1% is for the solitary stag horn stone. Regarding classification of stones, staghorn stones S3,S4,S5 accounted for 54,1%,31,8% and 14,1% respectively. The most often appropriate  puncture site was  lower calyx of kidney which accounted for 52,9%, middle calyx of kidney was 42,4% and upper calyx of kidney was 4,7%. Bleeding complication during surgery was 2,4%  by which blood transfusion was required. The mean operative time was 75,4 ± 18 minutes. The complication was 11.8% but mainly was  fever caused by post-surgery infections. The primary free-stone rate after PCNL  was 76,5%. There was 14 cases performed 2nd Mini PCNL and free stone rate  has been reported  at 89,4% after one month. Conclusion: Treatment of staghorn stones by mini percutaneous nephrolithotomy treatment at the Hospital of Post and Telecommunications is safe and effective method with high free-stone rates and less complications rate.
