Abstract

Purpose: We aimed to present our clinical experience with percutaneous antegrade ureteral stent placement in a single-center.


Methods
: Electronic records of the 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(SD) years) were included in the study. Patients were classified into two main groups: those with neoplastic disease and those with the non-neoplastic disease. Failure was defined as persistence of high level of serum creatinine or an inability to the placement of stents percutaneously. Post-procedural complications were grouped into percutaneous nephrostomy and stent placement related.


Results
: 727 procedures in 461 patients were included in the study. 654 procedures (90%) in 407 patients (88.3%) were neoplastic group and 73 procedures (10%) in 54 patients (11.7%) were non-neoplastic group. Our technical success rate was 97.7% and 100%, the complication rate was 3.1% and 4.1% for the neoplastic and non-neoplastic group, respectively. Furthermore, 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 from both malignant and benign causes when the retrograde approach has failed.
