I don't agree with dipstick tests being outdated.
Dipstick tests will not tell you the type of bacterial infection, that is not their job but they are mighty useful for measuring blood in urine (often undetectable to the naked eye), protein and pH levels. Only a culture will tell you the bacteria strain and which antibiotic type to treat it with. Then there is the good old microscope to see if there are any urinary crystals present.
Strange article. There are several ways of investigating urinary problems and with the best will in the world it can sometimes take more than one try to clear something up. How would they update these tests? Sometimes there can be a mental link to chronic conditions such as cystitis where unpleasant cases of irritable bladder or urethral spasm can set up a vicious circle even though there is technically no infection or obstruction or their causes present.
