Abstract
PURPOSE: We aimed to present our clinical experience with percutaneous antegrade ureteral stent placement in a single center. METHODS: Electronic records of patients who underwent percutaneous image-guided ureteral stent placement between September 2005 and April 2017 were reviewed. A total of 461 patients (322 males, 139 females; age range, 19-94 years; mean age, 61.4±15 years) were included in the study. Patients were classified into two main groups: those with neoplastic disease and those with non-neoplastic disease. Failure was defined as persistence of high level of serum creatinine or an inability to place stents percutaneously. Postprocedural complications were grouped as percutaneous nephrostomy and stent placement related complications. RESULTS: A total of 727 procedures in 461 patients were included in the study: 654 procedures (90%) in 407 patients (88.3%) were in the neoplastic group and 73 procedures (10%) in 54 patients (11.7%) were in the non-neoplastic group. Our technical success rates were 97.7% and 100% and complication rates were 3.1% and 4.1% in neoplastic and non-neoplastic groups, respectively. Seven stents retrievals and 112 balloon dilatations were performed successfully. CONCLUSION: Percutaneous antegrade ureteral stent placement is a safe and effective method for management of ureteral injuries and obstructions due to both malignant and benign causes when the retrograde approach has failed.
