A urinary tract infection ( UTI) is an infection that affects a part of the urinary tract. [ 1] Lower urinary tract infections may involve the bladder ( cystitis) or urethra ( urethritis) while upper urinary tract infections affect the kidney ( pyelonephritis ). [ 10] Symptoms from a lower urinary tract infection include suprapubic pain ...
Urethritis is the inflammation of the urethra. The most common symptoms include painful or difficult urination and urethral discharge. [1] It is a commonly treatable condition usually caused by infection with bacteria. [2] This bacterial infection is often sexually transmitted, but not in every instance; it can be idiopathic, for example. [3]
Urethral caruncle. A urethral caruncle is a benign cutaneous condition characterized by distal urethral lesions that are most commonly found in post-menopausal women. They appear red, and can be various sizes. They can have the appearance of a tumor. These epidermal growths are found around the posterior portion of the urethral meatus.
Anatomical terminology. [ edit on Wikidata] The urethra ( pl.: urethras or urethrae) is the tube that connects the mammalian urinary bladder to the urinary meatus. [ 1][ 2] In placental mammals, the urethra transports urine through the penis or vulva during urination and semen through the penis during ejaculation.
Urethral syndrome. Urethral syndrome is defined as symptoms suggestive of a lower urinary tract infection but in the absence of significant bacteriuria with a conventional pathogen. [1] It is a diagnosis of exclusion in patients with dysuria and frequency without demonstrable infection. [2] In women, vaginitis should also be ruled out.
A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows the passing of urine. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder. [1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis ...
S. saprophyticus causes 10–20% of urinary tract infections (UTIs). In females 17–27 years old, it is the second-most common cause of community-acquired UTIs, after Escherichia coli. [5] Sexual activity increases the risk of S. saprophyticus UTIs because bacteria are displaced from the normal flora of the vagina and perineum into the urethra ...
