We analyzed data from the VHI-30 after 1 year of DFS. Seventy-six patients (82%) returned questionnaires. The RFA group had a median total VHI-30 score of 11 (range: 9 to 15) and the open surgery group had a median total VHI-30 score of 50 (range: 17 to 55). The Mann-Whitney test indicated the RFA group had significantly better functional, physical, emotional, and total scores (P < 0.001 for all comparisons; Table 5). Analysis of the open surgery group indicated that patients with anterior commissure invasion had a worse VHI-30 total score (P = 0.02) and emotional score (P = 0.01;Table 6). Analysis of the RFA group indicated a worse VHI emotional score (P = 0.02;Table 6) in patients with anterior commissure invasion.
