Lichen sclerosus of the male genitalia and
urethral stricture diseases.

INTRODUCTION:
The true incidence of urethral involvement in patients with genital lichen
sclerosus (LS) is unknown. We review the epidemiology and discuss the
pathogenesis of LS and urethral stricture diseases.
MATERIALS AND METHODS:
During the period 1991-2002, of 925 patients who underwent urethroplasty for
anterior urethral stricture, 130 patients (14%) received the diagnosis of LS.
In all patients with LS the histology was re-examined to confirm the clinical
diagnosis. Retrograde and voiding urethrography was used to establish urethral
involvement in the disease.
RESULTS: In 106 patients (82%) the histology
provided the classical features of LS, and 24 patients (18%) showed some
histological variations. In 49 patients (37%) the LS involved the pendolous
urethra (meatus-navicularis-penile), and in 53 cases (41%) a panurethral
stricture was evident.
CONCLUSIONS: LS urethral involvement appears to be a
much more common and extensive disease than previously reported, and requires
particular care in its early diagnosis.
