The service, which was more than two years in development and has been in place since November last year, is starting to get noticed.
Clinical nurse specialist in urology Archie Auchinvole said the idea began after examining wait times for appointments.
"We were looking at our performance data in terms of patients waiting, patients overdue for surveillance, patients due to come to clinic for their first appointment and so forth.
"As a whole, we recognised the delay in the number of patients waiting for follow-up and that caused us a level of concern."
The work structure of nurses meant there was an opportunity to approach the matter differently, Mr Auchinvole said.
"We are a consistent presence as opposed to variable medical staffing numbers, and we had a structured model that provided us with a clear training programme. So that was the start of the idea."
Since the service began in November last year, 290 patients have been seen, with all 150 patients on the planned surveillance programme receiving their cystoscopy on time. The nurses are now completing 10 to 15 follow-ups every week.
But Mr Auchinvole said before it even got to that stage, he and fellow nurse practitioner Jen Gapuz had to complete 100 minimum supervised cystoscopies.
"You have to be confident and also empathetic about how we are approaching this with patients.
"Because if you have to come to hospital and someone's poking a camera inside your body on a regular basis, that can be a bit concerning.
"But I think the feedback that we get consistently about our approach is that we're quite gentle."
The feedback from the clinicians had been excellent so far, Mr Auchinvole said.
"I think they're pretty delighted because with the burden of clinical demand that's placed on them, they're on call constantly.
"So, if they know there's a stream of work in our urology, which is managing high-risk patients, that they don't have to worry about so much, I think that's probably beneficial for our surgeons."
Mr Auchinvole said through the process, they had gained more confidence in not only their work, but also in negotiating the equipment procurement issues.
Health Minister Simeon Brown praised the Dunedin Hospital team for their work and initiative.
“This initiative shows the value of empowering our skilled nursing workforce. By making better use of their expertise, we are improving access to care, supporting our specialists, and making sure patients receive timely, quality treatment."
