Abstract:
Objective:To investigate the therapeutic effect of dorsal skin-tightening technique on the correction of mild penile curvature in children with hypospadias.Methods:The clinical characteristics of hypospadias patients (95 cases) with mild penile curvature (<30°) after degloving penis during operation in our hospital from Jan 2017 to Sep 2020 were analyzed retrospectively. Group A: A new technique, reconstructing penile pubic angle at 12 o'clock position of penile dorsal side after degloving and suturing forskin outer and inner plate with tension at 12 o'clock position, was performed in dorsal skin-tightening group (43 cases). Gtoup B: while in dorsal midline tunica albuginea plication group (52 cases), Buck fascia was incised on dorsal midline area, following by tunica albuginea plication with one or two stitches. The patients in Group A were 0.4 to 1.5 years old, and the median age was 1.1 years, urethral orifice were located on distal shaft in 36 cases, proximal in 7 cases.The patients in Group B were 0.5 to 2.6 years old, and the median age was 1.5 years, urethral orifice were located on distal shaft in 41 cases, proximal in 11 cases. The penile ventral curvature degree was recorded during regular follow-up (postoperative 6 and 12 months), as well as postoperative complications.Results:Artificial erection test showed penile curvature was corrected during surgery by measuring with protractor. There was no chordee by measuring with the side photos in all patients during an average of 1.6 years follow-ups. There were 4 case of urethral fistula in Group B and 3 cases in Group A. No cases of urethrostenosis, diverticulum or concealed penis was recorded. The difference of postoperative complications had no statistical significance.Conclusion:Hypospadias with mild penile curvature could be effectively corrected by dorsal skin-tightening technique, which showed a good result of early follow-up.
