The possible causes of waiting a long time to urinate: first, male benign prostatic hyperplasia, when prostatic hyperplasia develops to a certain extent, the prostate gland protrudes to the center of the urethra causing local narrowing of the urethra, and causes the posterior urethra to lengthen, which is the resistance in the urethra is elevated, when urinating because of the urethral resistance is elevated and feel weak to urinate, and the waiting time to urinate is prolonged, sometimes need to use abdominal pressure to This usually occurs in patients with moderate to severe prostatic hyperplasia. This situation suggests a urological ultrasound to check if you have moderate to severe prostate hyperplasia, and if you are diagnosed, you need to take oral medication for prostate hyperplasia to improve your urinary waiting symptoms. The second, urethral strictures or urethral stones and other obstructive factors that lead to the presence of mechanical factors in the urethra resulting in increased pressure, then the pressure in the bladder to overcome the urethral resistance will be the symptoms of urinary waiting. In addition, the patient may have symptoms such as bifurcation of urine, pain in the urethra or hematuria in the naked eye. Ultrasound and urethroscopy of the urinary system are recommended to rule out diseases such as stones or urethral strictures, and to treat them accordingly to improve the symptoms of urinary waiting.
