Imaging Studies III: Computed Tomography

585
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies VII: Vascular Imaging

451
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Summary

Radiologists should recognize CT scan findings after laparoscopic partial nephrectomy (LPN) and hemostatic agents to avoid misinterpreting postoperative changes as tumor recurrence or abscesses.

Area of Science:

  • Radiology
  • Urology
  • Surgical Oncology

Background:

  • Laparoscopic partial nephrectomy (LPN) is a common procedure for kidney tumors.
  • Postoperative imaging interpretation can be challenging due to various findings.
  • Hemostatic agents used during LPN can alter CT scan appearance.

Purpose of the Study:

  • To describe the CT scan appearance of postoperative changes after LPN.
  • To identify common findings and potential complications.
  • To aid urologists and radiologists in accurate interpretation of LPN follow-up scans.

Main Methods:

  • Retrospective review of CT scans from 86 patients who underwent LPN.
  • Analysis of CT findings within 3 months post-surgery.
  • Categorization of postoperative changes including fluid collections, mass-like lesions, and gas formation.

Main Results:

  • Common findings included perinephric stranding, fluid collections, and mass-like lesions (35 cases).
  • Gas pockets were noted in 16 patients, sometimes persisting up to 40 days.
  • Postoperative changes can mimic tumor recurrence or abscesses, necessitating careful evaluation.

Conclusions:

  • Understanding the spectrum of CT findings after LPN is crucial.
  • Familiarity with the appearance of hemostatic agents aids interpretation.
  • Distinguishing normal postoperative changes from complications like recurrence is vital for patient management.
