There are acute and chronic urinary retention. Acute urinary retention is usually characterized by symptoms such as frequent urination, urgency, incomplete urination, difficulty in urination, etc., and in severe cases, inability to urinate; chronic urinary retention is characterized by easy distension of the lower abdomen, in which urine can be discharged but cannot be emptied, and is accompanied by the symptoms of acute urinary retention as well. It is usually treated with medication or surgery. Urinary retention is usually due to obstruction of the urethra, nerve damage caused by central nervous disorders, etc. The treatment for acute and chronic urinary retention is different, and can be treated with medication and catheterization. Patients with both acute and chronic urinary retention can be treated with neostigmine, sensitive antibiotics such as ofloxacin, and other medications to reduce inflammation and pain, depending on their condition. A more effective treatment for patients with acute urinary retention is catheterization, where a catheter is inserted through the urethra to drain the urine. If there is prostate hyperplasia or prostate cancer, which can not be catheterized, you can choose to choose to do permanent fistula surgery in the lower abdomen where the bladder is located, the effect is also better, can solve the urinary retention. Chronic urinary retention is treated by correcting the cause, such as benign prostatic hyperplasia. If this cannot be corrected, indwelling catheterization, clean intermittent catheterization, and cystostomy can be considered.
