Imaging Studies I: Kidney, Ureter, and Bladder Studies

884
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

External Anatomy of the Kidney

5.0K
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Kidney Structure

57.9K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Area of Science:

  • Urology
  • Oncology
  • Surgical Innovation

Background:

  • Existing renal tumor complexity systems can be overly complicated.
  • There is a need for a simpler, more accurate method to assess renal lesions.

Purpose of the Study:

  • To introduce and evaluate the zonal NePhRO scoring system for renal tumor complexity.
  • To compare the NePhRO score with the RENAL score in predicting surgical outcomes.

Main Methods:

  • A retrospective study of 166 patients undergoing open partial nephrectomy.
  • The zonal NePhRO score, based on four anatomical components, was assigned to each renal unit.
  • Scores were compared with the RENAL score, and perioperative data were collected.

Main Results:

  • The NePhRO score accurately predicted perioperative complications (P = .0008) on both univariate and multivariate analyses.
  • Clinical stage, blood loss, and tumor diameter correlated with the NePhRO score on univariate analysis.

Conclusions:

  • The zonal NePhRO scoring system is a simpler and effective tool for assessing renal tumor complexity.
  • This system aids in predicting surgical complexity and potentially improving patient outcomes.
