Abstract:
PURPOSE: The ureteral stent is very effective for the drainage of urine and maintenance of renal function in patients with ureteral strictures. Retrograde ureteral stunting is a common procedure. However, there is a need for antegrade ureteral stunting with percutaneous nephrostomy in cases of severe ureteral strictures. In these cases, retrograde exchange of ureteral stent is very difficult. Hence, we tried an easier and more efficient exchanging method available in these cases and also assessed its clinical results. MATERIALS AND METHODS: We performed retrograde ureteral scent exchange In the patients using the following procedure. First, the distal tip of the previously Inserted ureteral stunt was pulled out 2cm beyond the external meatus. Second, a guide-wire was inserted into the scent through the hole upto the kidney and then the stunt was completely removed. Third, a cystoscopic sheath without obturator was introduced into the bladder passing over the guide-wire. Fourth, a new ureteral stent was introduced into the ureter over the guide-wire with pusher. RESULTS: We experienced successful exchange of ureteral steno 95 times on 9 ureters in 8 patients with severe ureteral strictures who had antegrade ureteral stenting performed. CONCLUSIONS: From these results, we conclude that this exchanging method is very safe and effective.
