  1. aThree were treated with bilateral nerve preservation, and the remaining 95 had unilateral nerve preservation
  2. b“Recovery of continence” was defined as lack of necessity for using pads for urinary leakage
  3. c N = 306
  4. d N = 250
  5. eProstate weight refers to the weight of the resected prostate. Pearson’s chi-square tests were used for statistical analyses
