Office-Based Ureteroscopy Utilizing a Single Use Digital, Flexible Ureteroscope for Upper Tract Urothelial Carcinoma
What this study is about
This clinical trial tests how well office based ureteroscopy utilizing a single use digital, flexible ureteroscope works for the assessment of upper tract urothelial carcinoma. Ureteroscopy is a procedure in which a thin camera called a ureteroscope is used to assess patients with a known or suspected diagnosis of upper tract urothelial carcinoma.
View original scientific description
This clinical trial tests how well office based ureteroscopy utilizing a single use digital, flexible ureteroscope works for the assessment of upper tract urothelial carcinoma. Ureteroscopy is a procedure in which a thin camera called a ureteroscope is used to assess patients with a known or suspected diagnosis of upper tract urothelial carcinoma. Ureteroscopy is traditionally performed in an operating room under general anesthesia. In this study, patients undergo ureteroscopy in the doctor's office using an ultra-thin ureteroscope, which is the narrowest instrument of its kind. Because of its small size, researchers believe this procedure can be completed in the office with minimal discomfort and high patient satisfaction, which may eliminate the risks of general anesthesia and reduce delays to diagnosis. Office based ureteroscopy utilizing a single use digital, flexible ureteroscope may be effective for the assessment of upper tract urothelial carcinoma.

Primary outcome measures
Success rate
Time frame: On day of procedure
Defined as the ability to successfully perform and complete upper and lower tract surveillance with the 6.3 French ureteroscope in an office setting. A study-wide successful outcome will be defined as a success rate of 70%. The success rate will be reported as the count and proportion of participants with a successful outcome out of the number of enrolled participants. The corresponding 95% binomial Clopper-Pearson confidence interval will be reported.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Provision of signed and dated informed consent form
- Stated willingness to comply with all study procedures and availability for the duration of the study
- Male or female, aged ≥ 18 year. Both sexes are included to reflect the patient population with upper tract urothelial carcinoma (UTUC) already being followed at the University of Michigan and allow exploration of potential differences in tolerability of awake ureteroscopy based on sex
- History of endoscopically managed UTUC at any time, or a suspected diagnosis of UTUC based on pre-procedure imaging, and is already planned for office-based ureteroscopic assessment
- Ability and willingness to complete and adhere to survey questions and responses throughout study duration
Exclusion criteria
- Known ureteral strictures
- Active urinary tract infection
- Need for general anesthesia due to patient or procedural factors
- History of inability to tolerate ureteroscopy under local anesthetic
- Anticipated need for laser ablation during the surveillance procedure
Where
- Ann Arbor, Michigan

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
