Study Population

Study will enroll patients who are receiving a Boston Scientific Ureteral stent or Urinary Diversion Stent as part of their standard of care.

Description

Inclusion Criteria (for all Ureteral stent types except Urinary Diversion Stents):

• Subject is undergoing placement of a Boston Scientific Ureteral Stent
• Subject anatomy is appropriate to accommodate a stent size available in the study
• Subject is able to accurately detect and report bladder function and pain

• Subject is willing and able to:

  • Complete patient QoL questionnaire at specified time points (for subjects aged ≥ 18 years)
  • Return for all follow-up visits

Inclusion Criteria (for Urinary Diversion Stents):

• Subject is undergoing placement of a Boston Scientific Urinary Diversion Stent(s)
• The anatomical features of the involved renal collecting system are known by either prior or concurrent urography or axial CT imaging
• Subject is willing and able to return for all follow-up visits

Exclusion Criteria (for Ureteral stents and Urinary Diversion Stents):

• Subjects who meet any of the contraindications per individual stent DFU
• Subjects receiving different stent type in case of bilateral/multiple stenting
• Subjects with an indwelling ureteral stent(s) not planned to be removed prior to/or concurrently with the study stent implant

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Implanted Stents Meeting the Technical Success Criteria	Technical success was defined as: a stented kidney drains (to bladder) during the planned indwell time with no re-intervention due to obstruction of the stented ureters.	2 months to 15 Months
Primary Safety Endpoint	Any Serious Adverse Device Effects	2 months to 15 Months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Quality of Life - Patient-Reported Outcomes	Measurement System Patient Reported Outcomes Measurement Information System (PROMIS®) for subjects ≥18 years; Patient-Reported Outcomes Measurement Information System (PROMIS) - Pain Intensity 3a, score range for the change from Index procedure is -41.1 to 41.1; Patient-Reported Outcomes Measurement Information System (PROMIS) - Pain Interference 6b, score range for the change from Index procedure is -37.3 to 37.3 Higher PROMIS score means worse quality of life	Change From Index Procedure to Stent Removal Visit; Change From Index Procedure to Post Stent Removal Visit Stent Removal: Typically, within 2 weeks to < 365 days from Index Procedure Post-Stent Removal: Typically, 3 - 12 weeks from Stent Removal
Stent Migration	Stent Migration: Confirmed via imaging	2 months to 15 Months
