Hi, An isolated ovarian cyst
of less then 3 cm has no significance, It may just be a dominant follicle prior to ovulation. She may go for a repeat ultrasound
for her own satisfaction although it is not indicated. I don't know the reason why she did an ultrasound scan and what was the reason of urine testing? Epithelial cells
can be found in urine in a number of conditions including contamination from skin, vaginal secretions, inflammation of the urinary or genital tract etc. So, no conclusion can be drawn from a single report without first clinically reviewing the patient and considering her symptoms. Her abdominal pain
may point to a lower urinary tract
problem (may be infection). I think she should repeat a "clean catch mid stream specimen of urine" before making any further speculations. I hope this will clarify the picture. Best wishes.
