This definition of "FISH" was found at Web Cafe. I personally have never had the FISH test and don't know why...
FISH - also on WebCafe: an expert P.F. Bassi, MD, reviews FISH
Florescence in situ hybridization (FISH) is an assay which uses a mixture of fluorescent labeled probes to assess urinary cells for chromosomal abnormalities associated with malignancy.
The FISH method detected cancerous cells in the urine of 81 percent of the patients with bladder cancer,” said Kevin Halling, M.D., a Mayo Clinic pathologist and lead researcher on the study. “By comparison, urine cytology detected cancerous cells in only 57 percent of the patients with bladder cancer. “Most importantly, the FISH test picked up more than 95 percent of the high grade cancers, which are the most dangerous and important group of bladder cancers because they have a high probability of progressing to potentially incurable muscle-invasive bladder cancer,” says Dr. Halling. “With only one exception, the only cancers the test missed were low-grade tumors, which are less dangerous and have only a 3 to 5 percent chance of progressing to a higher stage tumor over five years.” The FISH test also detected recurrence of the cancer three to six months earlier than by the cytology, says Dr. Halling. This earlier detection capability should allow treatment to be initiated earlier and possibly give the patient a greater chance for survival, he said

I also had a FISH test, however mine came back negative even though I had 4 CIS spots removed two weeks later. My Uro said the FISH test is not always "spot-on",all the urine tests came back negative also.
My case (and .02 cents worth) CIS was considered a "flat head" tumor. It was red velvet spots. The first tumors removed were Ta Papillary (not sure if my spelling is correct) then 9 months later CIS was discovered during a 3 month cysto. I also thought CIS could treated and hopefully respond to BCG. I go next month for my 3 month cysto and that will also be my one yr. Hopefully, it will be clear. Of course, for the next week I will have my fingers and toes crossed
