  • Lower urinary tract infection (LUTI) is associated with an increased risk for prostate cancer, especially in patients with repeated medical visits for LUTI.

Why this matters

  • Inflammation of the prostate caused by cystitis and urethritis may play a role in the etiology of prostate cancer.

Key results

  • Compared with the group without LUTI, risk of developing prostate cancer was significantly higher in both the cystitis cohort (adjusted HR=1.46) and urethritis cohort (adjusted HR=1.72).
  • Further analyses found that there was a significantly greater risk of developing prostate cancer in patients with 5 medical visits per year for cystitis (aHR=9.25) and urethritis (aHR=9.68) vs the non-LUTI cohort.

Study design

  • A retrospective...
