ANTEGRAD URETERAL STENTING; INDICATIONS - METHODS - COMPLICATIONS AND RADIOLOGICAL APPROACH TO  COMPLICATIONS

Abstract:

Objectives

The aim of this study is to evaluate the indications, success rate, complications, technical success enhancing method, methods of antegrad ureteral stenting and the radiological management of complications due to retrograde and antegrade ureteral stenting in the treatment of ureteral obstructions and ureteral leaks caused by malignant and benign etiologies.

Materials and Methods

In this retrospective study, fluoroscopy and US-guided antegrade ureteral stenting procedures between January 2016 and December 2018 were examined. The study included 110 antegrade ureteral stenting and percutaneous nephrostomy in a total of 78 patients with 25 female patients (32.05 %), a mean age of 65.87 (20-90) and 53 male patients (67.94%) with a mean age of 68.73 (30-90).  Demographic data, antegrade ureteral stenting indications, procedure results and complications were evaluated for each patient.

Results

Antegrade ureteral stenting is a good alternative for patients with retrograde ureteral stent placement and already with percutaneous nephrostomy catheters. It has a high technical success rate and low complication risk. The use of the equipment used in other radiological procedures in antegrade ureteral stenting increases the technical success. Malposition,  perforation, hemorrhage, urinoma, abscess complications such as retrograde or antegrade ureteral stenting can be managed by radiological methods.
