What Are the Symptoms of a Bladder Obstruction?
Bladder neck obstruction refers to the occurrence of obstruction of a section of tubular structure extending from the inner urethral opening into the urethra by about 1 to 2 cm. The etiology is divided into congenital and acquired. Congenital causes are mostly due to hypertrophy of the bladder and neck muscles. Acquired persons often have fibroid contractures of the bladder and neck due to local chronic inflammation, which are more common in women than men, and often occur after middle age. Bladder neck stenosis and bladder neck sphincter and detrusor ataxia after prostate surgery can also cause bladder neck obstruction.

Bladder neck stenosis and bladder neck sphincter and detrusor ataxia after prostate surgery can also cause bladder neck obstruction.
- The clinical symptoms are mainly progressive dysuria, manifested as laborious urination, small flow of urine, weak injection, segmented urination, dripping urination, urinary retention and overflow urinary incontinence. Long-term obstruction can cause urinary tract infections and renal insufficiency.
- In addition to diagnosis based on clinical manifestations, the following tests are required:
- Cystoscopy
- Mirror sheath inserted
- Mild patients can take 1 blockers, or urethral dilatation. Patients with severe obstruction should undergo transurethral bladder neck incision or suprapubic bladder incision, wedge resection of bladder neck posterior lip, and bladder neck YV plasty.
