Phimosis ( tight foreskin) can be caused by BXO. Recent paper which was published from Sweden showed the partial circumcision with BXO showed poor outcome.
" Total circumcision was a benefecial treatment for many patients, but the majority still had active BXO after this surgical procedure. Complications of BXO were commonly seen and close cooperation between the dermatologist and urologist was needed for urethral dilatation, circumcision and in cases with suspected penile cancer. However, it was reassuring to see that the disease had gone into complete remission in 27% of our patients"
