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

EXPERIMENTAL

Treatment with Optilume for ureteric stricture

Device: Optilume

Interventions

OptilumeDEVICE

Has pre-treatment (balloon dilation or ureterotomy) followed by paclitaxel-coated balloon (Optilume) treatment of the ureteric stricture.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
  • +12 more criteria
