Imaging Studies I: Kidney, Ureter, and Bladder Studies

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...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

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. Intravenous Urography (IVU)Intravenous...

Imaging Studies III: Computed Tomography

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 Imaging01:19

Imaging Studies VII: Vascular Imaging

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

Ketamine abuse causes urinary dysfunction (KAUD) with characteristic imaging findings like bladder wall thickening and ureter dilation. Radiologists should recognize these signs, especially in patients with a history of ketamine use.

Area of Science:

  • Radiology
  • Urology
  • Toxicology

Background:

  • Ketamine abuse is associated with severe urinary tract symptoms.
  • Understanding the imaging manifestations of ketamine abuse-associated urinary dysfunction (KAUD) is crucial for diagnosis.

Purpose of the Study:

  • To summarize the characteristic imaging features of ketamine abuse-associated urinary dysfunction (KAUD).
  • To aid in the imaging diagnosis of KAUD.

Main Methods:

  • Retrospective analysis of imaging findings in 45 patients with KAUD.
  • Utilized ultrasonography, X-ray, CT, MRI, and SPECT.
  • Classified and evaluated common imaging characteristics.

Main Results:

  • Imaging changes predominantly affected the urinary and biliary systems.
  • Common findings included bladder wall thickening, reduced bladder volume, ureteral dilation, hydronephrosis, upper ureteral strictures, and renal impairment.
  • Dilation of the biliary system and inflammation of adjacent organs/lymph nodes were also observed.

Conclusions:

  • Ketamine abuse-associated urinary dysfunction exhibits typical imaging features.
  • Radiologists should consider KAUD when these characteristic changes are detected, particularly in patients with a known history of ketamine abuse.
