There was a very highly significant difference in RFS between the multicentricity and unicentricity groups (P = 0.00035) ( Fig. 2 ), and laser vaporization in patients with multicentricity was associated with a 4.7-fold higher risk of recurrence/persistence (hazard ratio (HR): 4.71, 95% CI: 1.87 - 11.88, P = 0.001).
