Few urethral diverticula are present at birth; the vast majority are acquired. Acquired urethral diverticula can be caused by trauma and/or infection. When the peri-urethral ducts become infected repeatedly, they can become blocked and eventually cause a<unk> . They are usually found in the middle of the urethra or the end farthest from the bladder. Congenital urethral diverticula can arise from several embryological sources. These include defects in the primordial folds and remnants of Gartner's duct.
