This pathology or sclerosis of the bladder neck is characterised by bladder neck hyperplasia or spasms combined with intersphincteric submucous fibrosis and extrasphinteric sclerosis.
In the primary form the anatomical disorder begins in new-born babies and children and the symptoms, including urinary frequency, soreness and dripping after urination, are manifested when the prostatic hyperplasia process begins and therefore urinary dysfunction can occur in subjects once they have reached approximately 30 years of age.
The secondary form can be caused by nervous tissue pathologies such as spinal cord damage and multiple sclerosis, or ensue from prostatic hyperplasia surgery (TURP), trans-urinary adenomectomy or following a radical prostatectomy to treat prostate cancer.
