Difficulty in urination is usually seen in bladder outlet obstruction and weak contraction of the bladder’s forced urinary muscles. A common condition that causes bladder outlet obstruction, is bladder neck sclerosis, in women, which causes obstruction of the bladder outlet, so the symptoms of difficulty urinating can occur. Weakness in the contraction of the bladder’s forcing muscles is mostly due to nerve damage. As a result of nerve damage, the muscles innervating the bladder cannot contract on their own, so when urinating, the symptoms of difficulty in urinating will occur. In addition, due to prolonged bladder outlet obstruction, it will make the bladder forced urethral muscle over-expanded, resulting in weak contraction of the bladder forced urethral muscle, which is also a very common cause of difficulty in urination in clinical practice. Difficulty in urination usually causes lower abdominal distension and pain, and usually requires timely catheter catheterization to expel the filled urine from the bladder in a timely manner, to avoid overfilling of the bladder, causing vesicoureteral reflux, which can lead to hydronephrosis.
