Answer

Complications of acute bacterial prostatitis include bacteremia, septic shock, prostatic abscess, epididymitis, seminal vesiculitis, and pyelonephritis. Suspect a prostate abscess if fever does not resolve within 48 hours; if confirmed, add anaerobic coverage and arrange for drainage.

Gonococcal and nongonococcal urethritis may progress to prostatitis, epididymitis, or orchitis, especially in younger patients. Urethral strictures (secondary to inflammation within the urinary tract) may form in up to 5% of patients; this must be kept in mind when evaluating patients with residual obstructive symptoms after treatment.

Other complications from UTI include fistula formation, recurrent infection, bacteremia, hydronephrosis and pyonephrosis, and gram-negative sepsis. Pyonephrosis refers to infected hydronephrosis associated with suppurative destruction of the kidney parenchyma, which results in nearly total loss of renal function.
