Kidney Transplant II: Surgical Procedure

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 donor...

External Anatomy of the Kidney

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...

Area of Science:

  • Radiology
  • Pathology
  • Surgical Oncology

Background:

  • Ectopic spleen, a rare condition, can present as a renal mass.
  • Accurate differentiation from renal tumors is crucial for appropriate management.

Observation:

  • A 54-year-old splenectomized female presented with an incidental left upper pole renal mass on ultrasound.
  • CT scan revealed a suspected renal neoplasm, leading to tumorectomy.

Findings:

  • Pathologic examination confirmed the mass as a supernumerary spleen, not a renal tumor.
  • This case highlights a rare presentation of ectopic splenic tissue.

Implications:

  • Splenic pseudotumors should be considered in the differential diagnosis of renal, adrenal, and retroperitoneal masses.
  • CT scan is the preferred imaging modality, with gammagraphy as a useful adjunct.
  • Conservative management is recommended for asymptomatic splenic pseudotumors.
