Fistulas between the bladder and vagina are common due to traumatic injury or necrosis, leading to painful complications. Diphtheritis presents as grayish infiltration on wounded surfaces with a tendency to spread over contiguous areas. Syphilitic ulcers can lead to recto-vaginal fistulae while tuberculous and carcinomatous ulcers are rare but destructive. The uterus' size, shape, and position indicate various conditions such as fibrous degeneration or hypertrophy of the lips of the os. Internal examination reveals changes in uterine walls, mucous membrane thickness, and color indicative of inflammation types. Mechanical lacerations during childbirth can cause severe gangrene and necrosis if untreated. <Callout type="important" title="Critical Observation">During internal examinations, noting the consistency and color of the uterine walls is crucial for diagnosing conditions such as fibrous inflammation or hemorrhagic changes.</Callout>
The uterus' position may change due to chronic inflammation or congenital irregularities, leading to prolapse or inversion. These changes can be primary or secondary to other conditions like tumors or adhesions. <Callout type="risk" title="Severe Complications">Untreated mechanical lacerations during childbirth can lead to severe gangrene and necrosis of the uterine walls, potentially resulting in perforation.</Callout>
Puerperal uterus is prone to numerous affections post-delivery, including involution changes that narrow the internal os. These conditions are critical for pathologists as they often cause death.
Key Takeaways
- Identify common fistula types and their causes.
- Recognize diphtheritis through grayish infiltration on wounded surfaces.

Practical Tips
- Use T-shaped incisions for thorough internal examination of the uterus.
- Pay attention to mucous membrane thickness and color during examinations.
Warnings & Risks
- Severe gangrene can result from untreated mechanical lacerations post-childbirth.
- Changes in uterine position may indicate underlying chronic inflammation or congenital issues.
Modern Application
While the diagnostic methods described here are outdated, understanding these historical pathologies provides valuable context for modern medical practitioners. The detailed descriptions of symptoms and conditions still hold relevance today, aiding in differential diagnosis and patient care.
Frequently Asked Questions
Q: What is the most common type of fistula mentioned?
The most common form of fistula described is between the bladder and vagina (^fistula vesico-vaginalis^).
Q: How can diphtheritis be identified in a patient?
Diphtheritis is characterized by gray or grayish-yellow infiltration on wounded surfaces that cannot be removed with water or scraping. It spreads over contiguous areas and appears dark red at the beginning of the affection.
Q: What causes changes in uterine position according to this chapter?
Changes in uterine position can result from chronic inflammation, congenital irregularities, adhesions, or tumors affecting the uterus's supports or surrounding tissues.
