Final answer:
When the urethral valve fails, it can lead to problems in urination, such as frequent urination and weak stream. This condition is known as benign prostatic hyperplasia (BPH) and is common in aging males. Treatments for BPH aim to relieve the pressure on the urethra.
Step-by-step explanation:
When the urethral valve fails, it can lead to various urinary problems. In males, the abnormal growth of the prostate gland can cause constriction of the urethra, leading to lower urinary tract symptoms such as frequent urination, weak stream, and incomplete bladder emptying. This condition is known as benign prostatic hyperplasia (BPH) and affects a significant percentage of males as they age. Treatments for BPH aim to relieve the pressure on the urethra, with medication or surgery to remove a portion of the prostate tissue.
