Turgut B, Bayraktar AM, Bakdık S, et al. - In patients with malignant ureteral obstruction (MUO), researchers ascertained if antegrade or retrograde methods should be preferred for double-J stent placement. For this investigation, they reviewed retrospectively the records of patients treated for MUO in the Urology and Interventional Radiology Clinic, Konya Training and Research Hospital. Benign aetiology patients have been excluded from the research. In total, 111 patients and 114 ureteral stenting treatments were involved. It was discovered that overall success rates were 95.2% using the antegrade ureteral stenting (AUS) method and 47.1% using the RUS method. In patients with or without tortuosity, the technical success of the antegrade method was significantly higher. In patients with hydroureteronephrosis, the technical success of the antegrade method was significantly higher. Overall, the authors concluded that the AUS technique should be the first choice in patients with MUO for double-J stent placement.
