Plain English summary of protocol

Background and study aims
Upper tract urothelial carcinoma is a type of cancer that affects the tubes connected to the kidney. Nephroureterectomy is surgery to remove the affected area. There is a risk of tumor recurrence. We aim to investigate if sterile water irrigation of the area during surgery decreases that risk.

Who can participate?
Patients aged 18 years old or above with upper tract urothelial carcinoma treated by nephroureterectomy.

What does the study involve?
Participants will be randomly allocated to receive sterile water irrigation during surgery or surgery as usual. Patients will be followed up for 2 years.

What are the possible benefits and risks of participating?
There are no risks of participating, but a chance to decrease the risk of later intravesical tumor recurrence if the study hypothesis is correct.

Where is the study run from?
Skåne University Hospital (Sweden)

When is the study starting and how long is it expected to run for?
May 2021 to September 2027
