Weakness of urination is usually seen in elderly men with neurogenic bladder, due to the damage of the nerves innervating the bladder, resulting in weak contraction of the bladder’s forced urinary muscles, which will easily result in the inability to discharge urine in time, and a large amount of urine accumulates in the bladder, causing distension and pain in the lower abdomen, resulting in urine retention. For this situation, the clinical relief can be through the indwelling catheter, through the indwelling catheter to drain the urine out of the bladder. As prolonged indwelling catheters tend to cause damage to the urethral mucosa and increase the chance of infection, they bring a lot of discomfort to many patients. In addition, many people consider suprapubic cystostomy, which is to make a fistula opening in the lower abdomen and insert a catheter to drain the urine out of the bladder, which can avoid the adverse effects of long-term indwelling urinary catheter.
