There were 2 duplications (abstract and manuscript). The overall success for PATIO is 88.2% (314\/356). The success rate was variable between classic PATIO (inversion at 87.2%), ligation-inversion at 86.9%, and ligation alone at 88.9%. The success rate was not improvised upon by supplementing inversion of UCF tract with ligation (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.957) or addition of a waterproofing layer (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.622). PATIO has been used for single or multiple UCFs post hypospadias repair, genital piercing, and genitoplasty in cis- or transgender population for UCF up to 5 mm in size. The success rates were best for UCF &lt;2 mm and worst for those approaching 5 mm. The results were, however, unaffected by the location of UCF along the penile shaft. Besides, the use of urethral catheter is optional and may be eliminated with shorter hospitalization.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n

(f) in patients unwilling for a urethral catheter, and (g) in hypospadias cripples wherein mobilization of distant tissues such as tunica vaginalis flap or a buccal mucosal graft may be required for
