Thanks for your query
Plenty of pus cells without any organism in geberal pyogenic culture in urine indicates presence of sterile pyuria
or tuberculosis. You need to start an antibiotic course preferably ciprofloxacin
500 mg twice daily for 2 weeks, take plenty of water around 4 litre/day with an urinary alkaliser. With these you need to have an USG of pelvic organ done to detect any lower abdominal pathology and should consult an urologist
to rule out any pathology in the urinary tract
. Cystoscopy should be done in refractory casses.
