Objective: To evaluate the safety and efficacy of antegrade percutaneous nephrolithotomy (PCNL) in patients with upper ureteral calculi ≥1.5 cm.Materials and methods: From November 2006 to May 2009, 44 consecutive patients with upper ureteral stones who were treated in our center were evaluated. In all cases, stones were located in the ureteropelvic junction (UPJ) or in 5 cm of proximal ureter and had greatest diameter ≥1.5 cm. Ultrasonography (USG) and intravenous urography (IVU) were performed in all patients before surgery. After the operation, radiography, USG, and IVU were conducted. The stone-free rate, mean operative and fluoroscopy time, complications, and hospital stay were assessed.Results: Mean patient age was 41.2 years, and mean stone size was 2.3 cm (range 1.5-3.0 cm). The stone-free rate was 81.8% at the end of the procedure. When 4 patients with clinically insignificant residual fragments
