Objectives: To present our large single-center experience in the management of autosomal dominant polycystic kidney disease (ADPKD) with total ultrasound (US)-guided percutaneous nephrolithotomy (PNL) and to evaluate the role of PNL under US in these patients. Patients and Methods: We retrospectively reviewed the charts of patients with ADPKD who underwent PNL from August 2011 to December 2019. A total of 56 patients were included in this study; all procedures were completed by the total US-guided technique. Demographic characteristics, operative parameters, and postoperative data were collected and analyzed. Results: Effective renal access was achieved in all patients. The mean stone size was 3.1 cm (range 1.7-6.5 cm). The initial stone-free rate was 70.6% (36/51); five patients underwent second-look PNL to remove residual stones. The other patients underwent oral medication therapy. No severe intraoperative complications occurred; one patient received selective embolization for bleeding on the contralateral side and one patient needed percutaneous drainage for perinephric abscess. Clavien I or II complications were seen in nine patients. Renal function was improved or stable in most patients; the condition of only one patient deteriorated after surgery. Conclusion: Total US-guided PNL is a safe and efficient treatment for kidney stones in patients with ADPKD; perioperative renal function was not adversely affected and complications were acceptable compared with patients in the general population.
