Ureters01:22

Ureters

2.0K
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

992
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...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

Uterine Tubes01:16

Uterine Tubes

3.4K
The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

Uterus and Cervix01:18

Uterus and Cervix

7.1K
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

2.5K
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.

Summary

A rare pediatric case involved a duplex kidney system where the upper part drained into the uterus. Surgical management included laparoscopic ureteroureterostomy, a minimally invasive technique.

Area of Science:

  • Pediatric Urology
  • Congenital Anomalies
  • Urogenital System Development

Background:

  • Duplex systems are common congenital anomalies of the upper urinary tract.
  • Ectopic ureteral insertion, particularly into the uterus, is exceptionally rare.

Observation:

  • A 13-year-old female presented with a right-sided duplex system.
  • The upper moiety's ureter was found to drain directly into the uterus.

Findings:

  • This represents only the second reported case in English literature of a duplex system with upper moiety ureteral ectopia into the uterus.
  • The patient underwent successful laparoscopic end-to-side ureteroureterostomy connecting the anomalous ureter to the normal ureter of the lower moiety.

Implications:

  • Highlights the importance of considering rare anatomical variations in pediatric urology.
  • Demonstrates the feasibility and efficacy of minimally invasive laparoscopic techniques for complex congenital anomalies.
  • Contributes to the limited literature on uterine ureteral ectopia, aiding future diagnosis and management strategies.
