|February 18, 2015
Summary
This case report details an extremely rare urinary bladder angiosarcoma in an 89-year-old man presenting with hematuria. The aggressive tumor metastasized rapidly, highlighting the challenges in diagnosing and managing this rare cancer.
Area of Science:
- Urologic Oncology
- Vascular Tumors
Background:
- Angiosarcoma of the urinary bladder is exceptionally rare and poorly understood.
- This report presents the 13th documented case globally.
Purpose of the Study:
- To report a rare case of primary urinary bladder angiosarcoma.
- To discuss the clinical presentation, diagnosis, and management challenges.
Main Methods:
- Case presentation of an 89-year-old male patient.
- Diagnostic imaging including CT-Urography and bone scan.
- Pathological examination of resected bladder mass.
Main Results:
- Patient presented with massive hematuria and was diagnosed with primary urinary bladder angiosarcoma.
- Imaging revealed a highly vascular bladder mass and spinal metastasis.
- The patient received palliative radiotherapy and died within 3 months.
Conclusions:
- Urinary bladder angiosarcoma is an aggressive malignancy with poor prognosis.
- Early diagnosis and effective treatment strategies remain critical challenges.

3.1K
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...

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease.

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...

01:23Urinary Bladder
4.6K
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...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

776
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...
