The length of the neourethra was 4.21\u2009\u00b1\u20090.63\u00a0cm in the modified TPIF group, 4.18\u2009\u00b1\u20090.71\u00a0cm in the traditional TPIF group, and 4.20\u2009\u00b1\u20090.68\u00a0cm in the Byar\u2019s two-stage group.

Seven (16.28%) cases of urethrocutaneous fistula occurred in the modified TPIF group, six (16.22%) in the traditional TPIF group, and eight (12.90%) in the two-stage group.
