Summary
A prolapsed ureterocele mimicked a perineural tumor in a woman with perineal pain. This rare condition, a prolapsed ureterocele, should be considered in the diagnosis of female meatal tumors.
Area of Science:
- Urology
- Medical Imaging
- Surgical Oncology
Background:
- Ureteroceles are congenital cystic dilations of the distal ureter.
- Simple ureteroceles can prolapse through the urethral meatus, presenting as a visible mass.
- Differential diagnosis of female meatal masses includes various benign and malignant conditions.
Observation:
- A 60-year-old woman presented with perineal pain and bleeding.
- A 30 mm hard mass protruding from the external meatus was noted.
- Imaging studies (CT, MRI, cystography) suggested an uncharacterized tumor.
Findings:
- Endoscopic examination revealed the mass spontaneously collapsed before resection.
- The collapsed mass was identified as a prolapsed simple ureterocele.
- No transurethral incision was required, and the patient remained free of complications at 11 months.
Implications:
- Prolapse of a simple ureterocele is a rare but important consideration in the diagnosis of female meatal tumors.
- This case highlights the importance of considering unusual presentations in urological diagnostics.
- Accurate diagnosis can prevent unnecessary invasive procedures.

01:22Ureters
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...
01:16Urethra
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...

01:19Anatomy 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...
01:26Urinary 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...
01:25Urinary 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...
01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
