What are the health problems of the urinary system?
Various health problems can arise in the urinary system. The most common conditions include: 1 Benign prostatic hyperplasia (BPH) or enlarged prostate: This occurs only in men and is a result of aging. The prostate is a walnut-sized gland that is located by the neck of the bladder, surrounding the urethra. As the prostate enlarges, it places pressure on the urethra. Such compression can cause the urethra to narrow and, in some cases, close completely. If this takes place, a patient may find it very difficult to urinate. 2 Kidney stones: Kidney stones are a common urological condition in both men and women. Kidney stones form when minerals and other solid substances accumulate in the kidneys or along any part of the urinary tract. When they're too large, these stones can block the flow of urine from the body. 3 Urinary tract infections (UTIs): Urinary tract infections also occur in both men and women. UTIs can be present in any part of the urinary system, from the kidney (pyelonephritis) to the bladder (cystitis) to the urethra (urethritis).
