[Magnetic resonance urography: possibilities and prospects]

Area of Science:

• Radiology
• Urology
• Medical Imaging

Background:

• Traditional excretory urography (EU) has limitations including contraindications like allergies and renal failure.
• Contrast agent excretion is crucial for effective EU, posing challenges in certain patient groups.
• Non-visualization of non-dilated urinary tracts can occur with EU.

Purpose of the Study:

• To evaluate the efficacy of Magnetoresonance Urography (MRU) as a diagnostic tool for various urinary tract conditions.
• To compare MRU with conventional excretory urography (EU) in terms of information provided and patient suitability.
• To explore the potential of MRU in cases where EU is contraindicated or ineffective.

Main Methods:

• Magnetoresonance urography (MRU) was applied to 25 patients aged 17-63.
• Patients presented with conditions including ureteral concrements, ureteropelvic stenosis, ureteral stenosis, urinary bladder tumor, and Ormond's disease.
• Data collected focused on visualization of urinary tract obstruction and dilatation.

Main Results:

• MRU provided comparable information to EU regarding urinary tract obstruction and dilatation.
• MRU successfully visualized urinary tracts in patients with EU contraindications (e.g., allergies, renal failure).
• MRU enabled visualization of non-dilated tracts in cases of medicinal polyuria.

Conclusions:

• MRU is a valuable non-invasive imaging technique for urinary tract visualization.
• MRU serves as an effective alternative to EU, particularly in patients with contraindications or poor contrast excretion.
• The absence of radiation and contrast agents makes MRU suitable for a wide range of patients, including pregnant women.
