| Summary: | Ureteral stent obstruction is a significant cause of morbidity and mortality from renal failure.Alternative options for decompression include tandem ureteral stents but the amount of material in the bladder may severely impair the quality of life.Following recurrent stent obstruction, a patient was fitted with tandem ureteral stent on both sides with a new nonrefluxing silicone end piece. After this procedure, renal function was improved with normal serum creatinine. The design of the new stent demonstrates the feasibility of the procedure. This new stent currently under prospective evaluation with tolerance questionnaire has demonstrated quite promising results in 10 patients.
