Abstract
OBJECTIVE: To present a reliable technique for fluoroscopic controlled, large-bore, ureteral stent placement and exchange in transplant kidneys with persistent ureterovesical strictures. MATERIALS AND METHODS: We reviewed the medical charts of all patients who underwent kidney transplant with persistent ureterovesical strictures who underwent ureteral stent placement or exchange at our institution between 2005 and 2015 using the new technique. Clinical characteristics and treatment outcomes of the study cohort were analyzed. RESULTS: Ureteral stent insertion or stent exchange, using this technique, was performed in 32 renal transplant units. Median operating time was 24 minutes (interquartile range, 21-36.75 minutes). The overall success rate of the technique at first attempt was 96.9%. In 1 patient, drainage of the transplanted kidney with a nephrostomy tube was indicated after procedure failure. No other local or systemic complications were encountered, and no stent encrustation was noted in this cohort of patients. Renal function remained stable in all patients during a median follow-up of 59 months (interquartile range, 28-61 months). CONCLUSION: Herein, we present in detail a step-by-step technique for the insertion and exchange of large-bore ureteral stents in transplanted kidneys. The technique was shown to be safe, effective, and highly successful.
