Urology Case Reports
|April 11, 2024
Summary
This case report highlights a rare congenital anomaly, retrocaval ureter, and its characteristic imaging findings. The study details a patient presenting with typical features across multiple imaging modalities.
Area of Science:
- Urology
- Radiology
- Medical Imaging
Background:
- Retrocaval ureter is an uncommon congenital anomaly where the ureter courses behind the inferior vena cava.
- This condition can lead to urinary stasis and complications like hydronephrosis.
Observation:
- A 38-year-old male presented with symptoms consistent with urinary tract abnormalities.
- The patient's demographics align with the classic profile reported for retrocaval ureter.
Findings:
- Ultrasound revealed characteristic signs suggestive of retrocaval ureter.
- Computed tomography (CT) and nuclear imaging studies confirmed the diagnosis by demonstrating the ureter's retrocaval course.
- Stereotypical imaging features were observed across all modalities.
Implications:
- Accurate and early diagnosis of retrocaval ureter is crucial for preventing long-term renal complications.
- Understanding the typical imaging features aids clinicians in identifying this rare anomaly.
- This case contributes to the literature on retrocaval ureter, emphasizing diagnostic imaging patterns.

01:22Ureters
469
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...

01:20Disorders of the Urinary System
298
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...

01:24Renal Tubule and Collecting Duct
959
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

01:23Urinary Bladder
655
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...
