Optimizing Pediatric Genital Reconstruction: The Role of Z-Plasty in Enhancing Aesthetic and Functional Outcomes

To assess the effectiveness, technical considerations, and long-term outcomes of the Z-plasty technique for correcting pediatric penile and scrotal anomalies.

A retrospective analysis of 100 consecutive Z-plasty procedures across various pediatric urological conditions was conducted. These included bifid scrotum reconstruction, chordee correction, penoscrotal webbing repair, and complex hypospadias reconstruction. Technical variations, including classic Z-plasty, multiple Z-plasties, and double-opposing Z-plasty configurations were evaluated. Patients were followed for a minimum of one year (range: 1-2 years), with 97% completing all scheduled follow up visits.

Z-plasty successfully addressed a spectrum of penile and scrotal abnormalities including 41 hypospadias revisions, 28 primary hypospadias repairs, 10 chordee corrections, and 21 other reconstructive procedures, through strategic modification of the number and angles of incisions. Primary skin flap healing was achieved in 98% of procedures. Only one case (1%) required healing by secondary intention due to suture line separation, and one (1%) developed a hypertrophic scar managed with local steroid application. All patients with complete follow-up (97%) demonstrated stable corrections with minimal visible scarring at final evaluation.

Z-plasty is a highly effective, versatile, and safe technique for pediatric genital reconstructive surgery. This adaptable approach enables optimal resurfacing and correction of diverse penoscrotal abnormalities with minimal morbidity. By minimizing linear scarring and redistributing tissue tension, Z-plasty simultaneously improves cosmetic outcomes and provides durable functional benefits. Future studies should focus on establishing standardized outcome measures and evaluating long-term results into adulthood.
