Trabecular formation of the bladder is generally a compensatory change of the bladder caused by lower urinary tract obstruction due to benign prostatic hyperplasia, etc. It is called trabecular bladder because of the trabecular structure of the bladder wall under cystoscopy. The most common cause of bladder trabeculation is benign prostatic hyperplasia. In addition, bladder fibrosis, bladder stones, urethral stenosis and other diseases that cause lower urinary tract obstruction may cause bladder trabeculation. Trabecular formation of the bladder is still more important, because it will cause frequent urination, urinary difficulties, urinary retention and other symptoms, thus affecting the patient’s life, in addition, it will also cause urinary tract infection, hydronephrosis and other complications, and in serious cases, it may even jeopardize the patient’s life.
