I learned something from Alyssa's question....
MSU = MID STREAM URINE
I don't know if you all can see the results of this table, but what it is saying is that urine cytology is not accurate for detecting low grade bladder cancer. This study showed 100% accuracy for large grade.
A Pakistani group did this study that is pretty easy to read.
Evaluation of initial, mid-stream and terminal urinary sample for cytology in follow up of bladder cancer and its comparison with cystoscopy
