Outcome Measures
Primary Outcomes (1)
Successful treatment
Rate of successful treatment defined as meeting all the following criteria: * Technical success * Freedom from retreatment of target stricture through six months post stent removal * Renogram at 6 months showing stability or improvement in split function for impacted kidney defined as split function within 10% of baseline value or improved from baseline. * T1/2 stability or improvement from baseline to 6 months for impacted kidney
6-months post ureteral stent removal (approximately 7 months post Optilume treatment)
Study Arms (1)
Optilume
EXPERIMENTALTreatment with Optilume for ureteric stricture
Interventions
Has pre-treatment (balloon dilation or ureterotomy) followed by paclitaxel-coated balloon (Optilume) treatment of the ureteric stricture.
Eligibility Criteria
You may qualify if:
- Age 18 years or older
- Single lesion ureteric or uretero-enteric stricture less than or equal to 4.0 cm in length
- Two functioning kidneys
You may not qualify if:
- Treatment of the target ureter with incision or balloon dilation within 3 months of the study treatment
- Subjects with more than one ureteric stricture
- Subjects with target stricture in bifid or duplicated ureter
- Known sensitivity to paclitaxel or on medication that may have negative interaction with paclitaxel
- Ureteric stricture caused by extrinsic compression of the ureter
- Unable to endoscopically access target stricture for any reason
- Existing stones in the ipsilateral kidney or ureter (except for asymptomatic kidney stones) that are in close proximity to the target ureteric stricture
- Chronic renal failure treated with dialysis
- eGFR \<30 mL/min/1.73m2
- Kidney function ≤ 25% of split function on the side with target stricture as measured by functional renogram
- Kidney function ≤35% of split function on the side opposite target stricture as measured by functional renogram or other significant pathology or impairment that may impact renal function
- Life expectancy less than 12 months
- Women who are pregnant or breastfeeding
- Women of child-bearing potential planning to get pregnant in the next year or are unwilling to use contraception over the next 12 months
- Males unwilling to abstain or use protected sex for 30 days post treatment
