Fossa navicularis stricture repair requires careful tissue selection for optimal urethral reconstruction and cosmetic results. The fasciocutaneous ventral transverse island flap is preferred for healthy penile skin, ensuring functional and aesthetic outcomes.

Area of Science:

  • Urology
  • Reconstructive Surgery

Background:

  • Fossa navicularis strictures present unique surgical challenges, demanding both urethral patency and cosmetic considerations.
  • Standard urethral stricture repair focuses on patency, but fossa navicularis reconstruction necessitates additional aesthetic attention.

Purpose of the Study:

  • To outline optimal surgical techniques for fossa navicularis stricture correction.
  • To emphasize the importance of tissue selection and reconstructive methods for functional and cosmetic success.

Main Methods:

  • Utilizing the fasciocutaneous ventral transverse island flap for penile skin substitution when healthy.
  • Considering extragenital tissue transfer for cases with penile skin inflammation or scarring.
  • Employing onlay substitution to preserve the dorsal urethral wall and performing glans-cap repair for glanduloplasty.

Main Results:

  • The fasciocutaneous ventral transverse island flap offers a well-vascularized, non-hair-bearing, and low-contraction substitute for glandular urethral reconstruction.
  • Substituting the entire diseased urethral length and preserving the dorsal wall prevents recurrence.
  • Glans-cap repair provides a simple, bloodless, and cosmetically superior method for glanduloplasty.

Conclusions:

  • Meticulous selection of non-diseased tissue and appropriate reconstructive techniques are crucial for successful fossa navicularis stricture repair.
  • Combining precise urethral substitution with effective glans reconstruction ensures satisfactory functional and aesthetic outcomes.
