Objectives: To evaluate the role of percutaneous nephrolithotomy in management of the patients with autosomal dominant polycystic kidney disease and associated nephrolithiasis.
Methods: A total of 19 patients with autosomal dominant polycystic kidney disease and upper urinary tract stones were included in the study. One patient had bilateral renal stones. Most of the stones were located in the renal pelvis and/or calices with a stone size >2 cm in the largest diameter. All patients were treated by percutaneous nephrolithotomy at 2 centers. Therefore, 20 percutaneous nephrolithotomy procedures were performed. Most of the procedures were performed in 1 stage by the urology team under fluoroscopic guidance; 6 cases were done in 2 stages. The success rate and morbidity and mortality of the technique and hospital stay were recorded.
Results: The pelvicaliceal system was successfully approached in all cases but 1. The overall stone-free rate was 89.4%. Renal function improved in the patients who presented with azotemia and was stable in the others. No patient died. Complications occurred in 3 procedures and consisted of mild postoperative hematuria in 1, bleeding through the nephrostomy tube in 1, and low-grade fever in 1. The mean hospital stay was 3 days.
Conclusions: Percutaneous nephrolithotomy is a safe and effective method for the treatment of patients with autosomal dominant polycystic kidney disease and associated upper urinary tract stones.

Percutaneous nephrolithotomy (PCNL) is the gold standard treatment for large kidney stones. Recent advancements in endoscopic technology and operative techniques have significantly increased the success rate of PCNL while reducing associated complications and morbidity. A key development contributing to this progress is the introduction of various new lithotripter techniques, which facilitate rapid stone fragmentation and clearance.

Background: Managing lower pole renal stones presents clinical challenges influenced by various factors such as stone size, location, and density. This study aims to assess the efficacy, safety, and stone-free rates of Flexible Ureteroscopy (FURS), Extracorporeal Shock Wave Lithotripsy (ESWL), and Mini Percutaneous Nephrolithotomy (Mini PCNL) for treating lower pole renal hard stones (< 2 cm).
Methods: A prospective single-centre comparative study was conducted on 414 adult patients with primary lower pole renal hard stones.

Background: Lower calyceal anatomy makes the stone clearance a difficult task across all treatment formats. Improvement in optics and miniaturization of instruments have offered an effective and safer alternative to percutaneous nephrolithotomy (PCNL). The study was conducted to compare the efficacy and complications associated with mini-PCNL vs standard-PCNL.

Objective: This study aims to identify the risk factors for systemic inflammatory response syndrome (SIRS) after minimally invasive percutaneous nephrolithotomy (PCNL) with a controlled irrigation pressure and to find which patients undergoing PCNL are likely to develop SIRS under the pressure-controlled condition.
Methods: A total of 303 consecutive patients who underwent first-stage PCNL in our institute between July 2016 and June 2018 were retrospectively reviewed. All the procedures were performed with an 18 F tract using an irrigation pump setting the irrigation fluid pressure at 110 mmHg and the flow rate of irrigation at 0.

To develop and validate a high-fidelity, nonbiohazardous simulator model for the ultrasound-guided percutaneous nephrolithotomy procedure. We employed a systematic framework based on Delphi consensus and modern education theory to design a simulation model. Twelve expert surgeons provided input through a hierarchal task analysis and identified procedural tasks, anatomical landmarks, and potential errors.
