Difficulty in urination in the elderly is divided into three conditions: 1. Prostatic hyperplasia, all in male patients with a history of prostate hyperplasia. When they have difficulty urinating, keep them in a standing position, apply a hot compress to the lower abdomen, and in a comfortable, private, and separate space, turn on the tap and let them listen to the sound of running water to induce urination. You can usually take medications that inhibit prostate enlargement, such as finasteride, and also use medications that dilate the smooth muscle of the urethra, such as tamsulosin, to improve the symptoms of urination. If there is still difficulty in urination or even urinary retention, catheterization or cystostomy must be given, and surgery will be performed at an optional stage. 2. urinary tract infection. Patients have symptoms of frequent, urgent and painful urination, so they are reluctant to drink more water and urinate, and they have difficulty urinating. Antibiotics and sodium bicarbonate are needed to improve the symptoms of urinary tract irritation signs, and patients are also advised to drink more water and eat a light diet.3. Anuric state. Anuria can also lead to difficulty in urination in the elderly. There are many factors for anuria, including urinary stones and tumors, which can lead to urinary obstruction, as well as renal failure and cardiac failure, which can also lead to anuria.
