What is the more scientific treatment method for bacterial prostatitis?

Patient's question:

38 years old, 5 months ago, accidentally contracted bacterial prostatitis, currently symptoms include left testicular swelling and pain, discomfort in the perineum and groin area, a feeling of damp scrotum

Doctor's answer:

Hello:
Treatment for Acute Bacterial Prostatitis: Rest in bed with intravenous fluids, digest calories, drink plenty of water, promote blood circulation, relieve spasms, and reduce fever. If there is difficulty urinating, avoid urethral catheterization as much as possible; if necessary, perform suprapubic cystostomy.
Antibiotics: Trimethoprim and sulfamethoxazole 800mg, taken twice daily. Alternatively, choose one of erythromycin, cephalosporins, tetracycline, ampicillin, or sulfonamide drugs as the primary medication. If the infection is caused by Gram-negative bacteria, use the sulfonamide drugs mentioned above.
