Intravenous Urography (IVU)
-
Definition: Intravenous urography is a radiological imaging technique used to visualize the urinary system, including the kidneys, ureters, and bladder.
-
Procedure: 1 โ A contrast medium is injected into a vein in the arm. 2 โ The contrast medium flows through the bloodstream and is excreted by the kidneys into the urine. 3 โ X-rays are taken as the contrast medium passes through the urinary system, producing images of the kidneys, ureters, and bladder.
-
Indications:
- Obstructive uropathy
- Renal calculi
- Tumors of the urinary system
- Trauma to the urinary system
- Infection of the urinary system
-
Normal Radiological Findings on IVU:
- The kidneys are outlined by a thin rim of contrast medium.
- The ureters are narrow and tortuous, filled with contrast medium.
- The bladder is filled with contrast medium, outlining its outline.
-
Abnormal Findings:
- Obstruction: The ureters are dilated, and the contrast medium is not excreted.
- Hydronephrosis: The kidneys are enlarged, and the contrast medium is not excreted.
- Calculi: The ureters or bladder contain stones, outlined by the contrast medium.
Homoeopathic Therapeutic Medicines:
- For Obstruction: Causticum and Lycopodium.
- For Hydronephrosis: Pulsatilla and Sepia.
- For Calculi: Calcarea carbonica and Ferrum phosphoricum.
Clinical Features of Obstruction:
- Acute pain in the abdomen or flank
- Nausea and vomiting
- Hematuria
- Urinary retention
Investigations for Obstruction:
- Urine analysis
- Blood tests
- IVU
- Ultrasound
Complications of Obstruction:
- Chronic kidney disease
- End-stage renal disease
- Peritonitis
Management of Obstruction:
- Medical treatment with diuretics and analgesics
- Surgical intervention to relieve the obstruction
- Urinary diversion procedures
Treatment of Obstruction:
- Conservative management with fluid replacement and analgesics
- Surgical intervention to relieve the obstruction
- Urinary diversion procedures
Bone Supply and Nerve Supply:
- The kidneys receive their blood supply from the renal arteries.
- The kidneys are innervated by the renal plexus.
Clinical Anatomy:
- The kidneys are located in the retroperitoneal space.
- The ureters are narrow and tortuous, passing from the kidneys to the bladder.
- The bladder is a muscular sac that stores urine.
Types of Obstruction:
- Extrarenal obstruction: Obstruction caused by external factors, such as tumors or stones.
- Intrinsic obstruction: Obstruction caused by a problem within the kidney, such as a tumor or scar tissue.
Causes of Obstruction:
- Renal calculi
- Tumors of the urinary system
- Trauma to the urinary system
- Infection of the urinary system
Clinical Features of Hydronephrosis:
- Abdominal pain
- Nausea and vomiting
- Hematuria
- Urinary retention
Investigations for Hydronephrosis:
- Ultrasound
- IVU
- Computed tomography (CT) scan
- Magnetic resonance imaging (MRI)
Complications of Hydronephrosis:
- Chronic kidney disease
- End-stage renal disease
- Peritonitis
Management of Hydronephrosis:
- Medical treatment with diuretics and analgesics
- Surgical intervention to relieve the obstruction
- Urinary diversion procedures
Treatment of Hydronephrosis:
- Conservative management with fluid replacement and analgesics
- Surgical intervention to relieve the obstruction
- Urinary diversion procedures
