Summary

A 5-month-old infant underwent electro-resection for subvesical stenosis, resulting in a urethral defect. A bladder mucosal graft successfully repaired the penoscrotal junction defect.

Area of Science:

  • Pediatric Urology
  • Surgical Reconstruction
  • Genitourinary Tract Anomalies

Background:

  • Subvesical stenosis in infants can lead to significant urethral complications.
  • Urethral defects pose challenges in pediatric reconstructive surgery.
  • Early intervention is crucial for optimal outcomes in congenital genitourinary anomalies.

Observation:

  • A 5-month-old male infant presented with subvesical blind-hole stenosis.
  • Following electro-resection, a 3 cm urethral defect was identified at the penoscrotal junction.
  • The defect involved the distal urethra, requiring complex reconstruction.

Findings:

  • Successful reconstruction of the 3 cm urethral defect was achieved using a free mucosal graft.
  • The graft was harvested from the urinary bladder.

  • The Memmelaar and Hendren technique was employed for the graft placement.

    • Implications:

    • Free mucosal grafts are a viable option for repairing long-segment urethral defects in infants.
    • This technique offers a potential solution for challenging penoscrotal junction reconstructions.
    • Preservation of urethral continuity and function is paramount in pediatric urology.
