Pathologies of the Urinary System

Published on 6th September 2019

It is important once you have successfully taken your exam for your anatomy and physiology courses, and qualified in a therapy, that you understand about when things go wrong with the body, so that you can treat safely. 

Here is a list of diseases and disorders of the urinary system, otherwise known as pathologies.

Diabetes Insipidus

This is where a person urinates frequently and is always thirsty, due to a lack of the hormone vasopressin which usually stimulates the kidneys to concentrate  urine and retain water in the body


is a group of diseases that injure the part of the kidney that filters blood (called glomeruli). Other terms you may hear used are nephritis and nephrotic syndrome. When the kidney is injured, it cannot get rid of wastes and extra fluid in the body.

Urinary tract infections

Urinary tract infections (UTIs) are common infections that can affect the bladder, the kidneys and the tubes connected to them.

Anyone can get them, but they're particularly common in women. Some women experience them regularly (called recurrent UTIs).

UTIs can be painful and uncomfortable, but usually pass within a few days and can be easily treated with antibiotics.


is inflammation of the urethra. That's the tube that carries urine from the bladder to outside the body. Pain with urination is the main symptom of urethritis.Urethritis is commonly due to infection by bacteria.


Painful urination


Involuntary urination, especially by children at night causing bed-wetting


the unintentional passing of urine due for example to a weak or damaged bladder. Common after giving birth


A rare malignant renal tumor, typically affecting children


A raised level in the blood of urea and other nitrogenous waste compounds that are normally eliminated by the kidneys.
