|July 3, 2018
Summary
Urinary schistosomiasis caused by Schistosoma haematobium can mimic advanced bladder cancer with lung metastases. Prompt diagnosis and treatment with praziquantel resolved symptoms, highlighting the importance of considering parasitic infections in differential diagnoses.
Area of Science:
- Medical Parasitology
- Urology
- Infectious Diseases
Background:
- Schistosomiasis, particularly genitourinary schistosomiasis caused by Schistosoma haematobium, is a significant parasitic disease.
- It typically affects the bladder, leading to acute and chronic manifestations.
Observation:
- A case presented with initial findings suggestive of advanced bladder cancer and pulmonary metastases.
- Computed tomography scans revealed pulmonary changes initially interpreted as metastases.
Findings:
- Further investigations ruled out malignancy, and pulmonary changes resolved with treatment.
- Cystoscopic findings and resolution after praziquantel treatment confirmed urinary schistosomiasis.
- Pulmonary involvement without hepatosplenic disease is unusual but can occur due to egg deposition causing granulomatous reactions.
Implications:
- This case underscores the importance of considering Schistosoma haematobium infection as a differential diagnosis for haematuria and suspected lung metastases.
- Urinary cytology and awareness of travel history to endemic areas are crucial for accurate diagnosis.
- Highlights the need for clinicians to be aware of parasitic mimics of malignancy.

01:23Urinary Bladder
3.5K
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...

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:13Introduction to Urinary System
9.2K
The urinary system consists of two kidneys, two ureters, the urinary bladder, and the urethra.
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
