Hi. what r her urinary symptoms. She frequently needs to pee or has burning sensation in urine or urge is severe enough that she has to rush to toilet. These can be linked to UTI. There can be several causes of perineal itch, like poor perineal hygiene, UTI, STDs, tight undergarments, anal problems like fissure, constipation, worm infestation, vaginal discharge, pelvic inflammatory disease, etc. What does fresh urine routine say...numerous pus cells... if yes she could have UTI. Get urine culture and treat with culture sensitive antibiotics. If culture neg, rule out tuberculosis in urine. Get urine for AFB with 3early morning samples. Since she is having recurrent suspicious UTI...Maintain perineal hygiene, avoid public toilets, prevent constipation, deworm her, take long term low dose culture sensitive prophylactic antibiotic for 2-3 months.
