Clinical efficacy of transverse preputial island flap urethroplasty for single-stage correction of proximal hypospadias: a single-centre experience in Chinese patients

BACKGROUND: This study was designed to summarize the clinical outcomes of transverse preputial island flap urethroplasty for single-stage correction of proximal hypospadias in our hospital. METHOD: This study retrospectively analysed the clinical data, including the preoperative general information, intraoperative and postoperative data, and follow-up data, of 155 children with proximal hypospadias who were admitted to our hospital from January 2009 to January 2019. RESULTS: During follow-up, a total of 92 postoperative complications occurred, and 41 patients underwent reoperation. There were 49 patients with urinary fistula, 26 patients with urethral stricture, 9 patients with urethral diverticulum and 8 patients with urinary tract infection. Regarding the family members’ satisfaction with the cosmetic appearance of the penis, the satisfaction rate with the urinary meatus was 85.2%, the satisfaction rate with the glans appearance was 87.7%, the satisfaction rate with the the appearance of the foreskin of the penis was 92.3%, and the satisfaction rate with the overall penis shape was 89.0%. CONCLUSION: Proximal hypospadias is a serious condition that is often combined with severe chordee, and transverse preputial island flap urethroplasty for single-stage correction is an effective surgical procedure for treating this condition.
