Insights

A rare retroperitoneal enteric duplication cyst in a child caused urinary issues by connecting to the kidney. Surgical removal resolved the symptoms, highlighting a unique case of ectopic gastric mucosa impacting the urinary system.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Urology

Background:

  • Enteric duplication cysts are rare congenital anomalies, typically found in the gastrointestinal tract.
  • Isolated retroperitoneal enteric duplication cysts are exceptionally uncommon.
  • Ectopic gastric mucosa within these cysts can lead to complications due to acid secretion.

Observation:

  • A 9-month-old male presented with hematuria, dysuria, and anemia.
  • Imaging revealed a retroperitoneal cyst adjacent to a hydronephrotic right kidney.
  • Surgical exploration identified a communication between the cyst and the right pelviureteric junction.

Findings:

  • Histological examination confirmed an enteric duplication cyst lined by ectopic gastric mucosa.
  • The cyst was directly communicating with the urinary system at the right pelviureteric junction.
  • This represents the first reported case of such a communication in the English literature.

Implications:

  • Ectopic gastric mucosa in enteric duplication cysts can cause urinary tract symptoms through acid secretion.
  • Prompt surgical excision of the cyst and affected kidney is curative.
  • This case expands the understanding of rare congenital anomalies and their clinical presentations.

Ureters01:22

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...

Anatomy of the Genitourinary System I: Kidneys and Ureters

The upper urinary system comprises two kidneys and two ureters, which are crucial in filtering blood and forming urine.KidneysLocation and Structure:The kidneys are two bean-shaped organs positioned behind the peritoneum on either side of the spine.Kidneys are between the 12th thoracic (T12) and the 3rd lumbar (L3) vertebrae.The position of the liver causes the right kidney to sit slightly lower than the left.Protective Layers:Each kidney is enveloped in a tough, fibrous membrane called the...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Urologic 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...

Urinary Bladder01:23

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...
