ICD-10 online (WHO version 2019) |
Vaginal stones , called vaginal calculus ( plural : vaginal calculi ) or vaginolith in the English-language specialist literature , are extremely rare pathological mineral foreign bodies ( concretions or biominerals ) that can arise in the vagina .
etiology
A distinction is made between primary and secondary vaginal stones. Both forms have a different cause ( etiology ). Primary vaginal stones are caused by urine congestion ( urinary stasis ) in the vagina, with or without obstruction of the vaginal outlet . Secondary vaginal stones, on the other hand, are the result of the crystallization of constituents of the urine around a foreign body in the vulva and vagina. Primary vaginal stones are more common than secondary ones.
Obstruction of the vaginal outlet, as well as urinary incontinence , can lead to chronic accumulation of urine within the vagina. There - similar to the urinary stones in the urinary bladder - vaginal stones can form as concretions, which increase in size over time. In addition to obstruction of the vaginal outlet , vesicovaginal fistulas (VVF) can also cause chronic urine buildup in the vagina. A vesicovaginal fistula is an abnormal connection ( fistula ) between the bladder ( Latin: vesica ) and the vagina. A urethrovaginal fistula (UVF, connection between the ureter and the vagina) also leads to a build-up of urine in the vagina, which promotes the formation of vaginal stones. The same applies to a ureter (a Fehlmündung the ureter outside the bladder triangle , the trigone vesical ). The incidence of vaginal stones is also apparently increased with the extreme execution of a circumcision of female genitals , the so-called introcision (scraping of skin and tissue from the vagina).
Secondary vaginal stones form around foreign objects in the vagina. These can be, for example, non- absorbable sutures or gauze that remain in the vagina after the operation of a vesicovaginal fistula. These foreign bodies are then iatrogenic ('created by the doctor') in origin. Other foreign objects that have been introduced into the vagina and remained there can also be the cause of secondary vaginal stones. These include, for example, pessaries , intrauterine devices ('spirals'),
Vaginal stones can sometimes reach considerable sizes due to their progressive growth. Vaginal stones with a diameter of, for example, 8 cm are found in the literature.
Clinical picture
In many cases, vaginal stones are not clinically relevant and are more of an incidental finding. However, they can reach a size at which they obstruct various organs in their function. For example, the ureters can become blocked, which can lead to kidney failure .
diagnosis
Due to the relative rarity of vaginal stones, making a diagnosis is often very difficult and requires a doctor who is aware of the possibility of this diagnosis. For disabled children which is incidence obviously higher.
The formation of vaginal stones is a very slow process that, as long as it is symptom-free, is only an incidental finding. Vaginal stones can be easily identified using imaging methods such as x-rays or computed tomography (CT) of the pelvis. When x-raying, lateral and frontal imaging is recommended for precise localization and organ allocation. Diagnosis is much more difficult with sonography ("ultrasound").
Even after the X-ray, vaginal stones are initially usually misinterpreted as bladder stones . Excretory urography can be used to differentiate between bladder stones and vaginal stones. A reliable diagnosis is usually possible with colposcopy (vaginoscopy, vaginaloscopy).
therapy
Due to their rarity, there are no general guidelines for removing these pathological foreign bodies. The methods of removing the vaginal stones depend on the exact location and size of the concretions. Smaller stones can, for example, be removed minimally invasively using lithotripsy . Often they can also be removed through the vaginal canal with Wrigley obstetric forceps ( Wrigley's Forceps ).
Larger stones may have to be removed from the vagina via a perineal incision (episiotomy). Open surgery can also be indicated.
In addition, in many cases, the elimination of the causes of vaginal stone formation is indicated.
