Ultrasonography-Guided Percutaneous Nephrolithotomy for the Treatment of Kidney Stone

Abstract

Abstract. We examined the surgical outcomes of minimally invasive percutaneous nephrolithotomy (MPCNL) in complicating urolithiasis.10 patients were hospitalized for MPNCL due to upper tract urolithiasis. Calyx puncture was performed in the prone position under ultrasonographic guidance. The renal access route was established using a set of 8F-12F dilators, and a transpyelic ballistic lithotriptor was used to fragment calculi. The entire operative time was approximately 40-60 min, and the mean time of establishing percutaneous access was 20 min. The calculi were completely removed by single-session pneumatic lithotripsy. The 10 patients recovered from MPCNL uneventfully, and the follow-up radiological examinations identified no stone residual or recurrence.MPCNL is a minimally invasive modality that is effective and safe for the treatment of urolithiasis in patients.
