A Prospective Clinical Assessment of Office-Based Ureteroscopy for Upper Tract Urothelial Carcinoma Utilizing a 6.3 French Single Use Digital Flexible Ureteroscope

Who can join

Ages 18 and older · All sexes

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
* Pregnancy

About the study

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.
