The Δ score (prescore – nadir score after RARP) for each nerve-sparing technique groups in sexual and urinary scores. Group 0, non-nerve-sparing; group 1, unilateral ITR-NS; group 2, unilateral ITE-NS; group 3, bilateral ITR-NS; 4, bilateral ITE-NS. (A) Sexual summary scores (SS; mean ± SD). Group 0, 21.9 ± 17.5; group 1, 26.8 ± 19.9; group 2, 19.7 ± 16.2; group 3, 15.8 ± 19.4; group 4, 20.9 ± 19.9. ANOVA demonstrated significant differences between groups (P = 0.006). (B) Sexual function scores (SF; mean ± SD). Group 0, 23.5 ± 19.0; group 1, 26.9 ± 21.4; group 2, 23.4 ± 19.4; group 3, 20.4 ± 18.4; group 4, 22.2 ± 20.7. There were no significant differences between groups (P = 0.345). (C) Sexual bother scores (SB; mean ± SD). Group 0, 22.4 ± 29.9; group 1, 29.7 ± 31.4; group 2, 16.8 ± 31.2; group 3, 4.1 ± 31.4; group 4, 21.7 ± 33.2. ANOVA demonstrated significant differences between groups (P < 0.001). (D) Urinary summary scores (US; mean ± SD). Group 0, 27.4 ± 18.6; group 1, 29.9 ± 18.9; group 2, 29.1 ± 19.7; group 3, 13.9 ± 13.3; group 4, 23.0 ± 18.9. There are significant differences between groups (P < 0.001). (E) Urinary function scores (UF; mean ± SD). Group 0, 37.8 ± 23.4; group 1, 39.0 ± 23.2; group 2, 37.9 ± 24.5; group 3, 19.9 ± 16.4; group 4, 37.0 ± 22.6. There are significant differences between groups (P < 0.001). (F) Urinary bother scores (UB; mean ± SD). Group 0, 21.4 ± 18.4; group 1, 22.5 ± 19.3; group 2, 22.8 ± 19.5; group 3, 8.7 ± 14.3, group 4, 14.2 ± 17.9. There are significant differences between groups (P < 0.001). (G) Urinary irritative–obstructive scores (UIR; mean ± SD). Group 0, 14.2 ± 16.4; group 1, 15.8 ± 18.7; group 2, 14.8 ± 18.4; group 3, 3.25 ± 9.8; group 4, 9.8 ± 17.3. There are significant differences between groups (P < 0.001). (H) Urinary incontinence scores (UI; mean ± SD). Group 0, 52.8 ± 32.2; group 1, 55.2 ± 30.9; group 2, 52.1 ± 31.8; group 3, 30.7 ± 24.2; group 4, 47.7 ± 30.6. There are significant differences between groups (P < 0.001).
