Query 5mm Kidney Stone. Are my options?

Recovered from a UTI Kidney infection in right kidney in March. Follow up USG AND CT scan showed a kidney stone present in the same Kidney. CT scan showes size of 6.3mm. was prescribed medications and pottasium citrate drink. After a month, updated CT scan showed it reduced to 5mm. There has been no pain or discomfort at all. Updated Urine Analysis shows Color is pale yellow but slightly hazy. Pus Cells are 5-6. 2 weeks ago urine test showed pus cells were 10-12. Bacteria still detected. Rest of the parameters were within range. Will surgery be required to remove stone? Is the passing of kidney stone usually this slow? What are my options? Attaching latest CT result I am also diabetic. I monitor blood sugar and blood pressure and both are in control
