As the prostate enlarges, it compresses the ___________ and causes urinary ________.

As the prostate enlarges, it compresses the urethra, which is the tube that carries urine from the bladder out of the body. This compression can create a blockage that hinders the flow of urine, leading to urinary retention. Urinary retention occurs when the bladder does not empty completely, causing discomfort and potentially leading to complications if not addressed.

The relationship between the prostate and the urethra is crucial in understanding conditions like benign prostatic hyperplasia (BPH), which is a common issue in older men. The enlargement of the prostate can significantly narrow the urethra, directly impacting the ability to urinate normally. In cases of severe compression, it may become difficult to start urination or fully empty the bladder, thus illustrating how the enlargement directly relates to urinary retention.
