Gj. Alter et al., USE OF A PREFABRICATED TUNICA VAGINALIS FASCIA FLAP TO RECONSTRUCT THE TUNICA ALBUGINEA AFTER RECURRENT PENILE PROSTHESIS EXTRUSION, The Journal of urology, 159(1), 1998, pp. 128-132
Purpose: Although a penile prosthesis usually perforates into the uret
hra, it can extrude through the glans or corporeal shaft. Various mate
rials have been used to reconstruct tunica albuginea but no method of
repair has been satisfactory in such difficult cases. Repair of the we
akened tunica albuginea should ideally be performed with autogenous ti
ssues. Inasmuch as the scarred tissue bed is inadequate to ensure graf
t survival and no local flaps are available for this purpose, prefabri
cation of a local flap has been designed. Materials and Methods: We pr
esent 2 cases in which the distal corpus was reconstructed with a pref
abricated tunica vaginalis fascia flap. The first stage involves graft
ing rectus fascia onto the external tunica vaginalis of the testicle.
At the second stage the prefabricated tunica vaginalis fascia flap is
transposed to the distal corpus, placing it as a buttress between the
cylinder and urethra medially or between the cylinder and thin lateral
and distal tunica albuginea. The flap also replaces part of the tunic
a albuginea. Results: In both patients repair of the tunica albuginea
was successful and each has a functioning inflatable penile prosthesis
at 2 1/2 1 1/2 years postoperatively, respectively. Conclusions: Reco
nstruction of the weak tunica albuginea with a prefabricated tunica va
ginalis fascia flap is an excellent procedure in these difficult cases
.
