When an elderly person feels the urge to urinate but is unable to do so, this is generally referred to as difficulty in urination. Difficulty in urination may be caused by benign prostatic hyperplasia, urinary stones, and lesions in the bladder. 1. Benign Prostatic Hyperplasia: This disease is common in elderly male patients, with the gradual increase in age, hormonal changes as well as an imbalance between cell proliferation and apoptosis may lead to benign prostatic hyperplasia. When the hyperplastic prostate tissue presses on the urethra, it can lead to narrowing of the urethra, which may cause difficulty in urination. 2. Urinary stones: Elevated or oversaturated concentrations of crystalline material in the urine accumulate locally and eventually form stones. When the stone is too large, it will block the urethra and cause sudden interruption of urination, as well as difficulty in urination, most commonly seen in the lower urinary tract stones. 3. Lesions in the bladder: such as bladder tumors, a large number of blood clots in the bladder caused by various reasons. When blood clots or tumors appear in the bladder neck and urethra, it is easy to block the urethra resulting in the inability to completely discharge urine. Difficulty in urination will then occur, the urine line becomes thinner and may be accompanied by pain in the bladder area after the patient holds his urine. When the symptom of difficulty in urination occurs, it is recommended that the patient seeks medical treatment in a timely manner, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
