Summary
A severe pelvic fracture can cause complete vaginal avulsion while sparing the urethra. This case highlights the strong connection between the urethra and anterior vaginal wall, crucial for understanding pelvic trauma.
Area of Science:
- Urology
- Anatomy
- Trauma Surgery
Background:
- The precise anatomical support of the female urethra remains a subject of debate.
- Pelvic fractures can lead to complex injuries affecting pelvic organs.
Observation:
- A case report details an 18-year-old female pedestrian involved in a motor vehicle accident.
- The patient sustained a pelvic fracture resulting in the avulsion of the intact vagina and urethra from the symphysis pubis.
Findings:
- Surgical reevaluation confirmed the urethra and vagina were avulsed from the symphysis pubis but remained intact.
- Successful surgical reapproximation of the avulsed structures to the periosteum and surrounding soft tissues was achieved.
- No urogenital sequelae were observed postoperatively.
Implications:
- Complete anterior vaginal wall avulsion can occur with preservation of the lower urinary tract following pelvic fractures.
- This case reinforces the anatomical understanding of a robust and dense attachment between the urethra and the anterior vaginal wall.
- The findings have implications for surgical management and understanding pelvic floor anatomy in trauma cases.

Anatomy of the Genitourinary System II: Bladder and Urethra
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
Urinary Tract Calculi VI: Surgical Management
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
Ureters
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...
Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Muscles of the Pelvic Floor and Perineum
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
