Summary
This study introduces a novel retrograde urethrography technique using a vacuum uterine cannula, avoiding urethral instrumentation. The method effectively visualizes urethral strictures without causing iatrogenic damage, offering a safer diagnostic option.
Area of Science:
- Urology
- Medical Imaging
- Diagnostic Techniques
Background:
- Traditional retrograde urethrography often involves urethral instrumentation.
- Instrumentation can lead to iatrogenic damage and discomfort.
- Alternative methods are needed for diagnosing urethral strictures, especially in cases of meatal stenosis.
Purpose of the Study:
- To describe a new device and technique for performing retrograde urethrography.
- To evaluate the safety and efficacy of non-instrumental retrograde urethrography.
- To assess the visualization of urethral strictures and iatrogenic damage.
Main Methods:
- Retrograde urethrography was performed in 160 male patients.
- A vacuum uterine cannula was utilized for the procedure, avoiding direct urethral manipulation.
- The study focused on evaluating distal urethral strictures and any signs of iatrogenic damage.
Main Results:
- The novel technique successfully visualized distal urethral strictures in 12 out of 160 patients.
- No instances of iatrogenic damage to the urethra were reported in any patient.
- The vacuum uterine cannula proved effective in facilitating retrograde urethrography without complications.
Conclusions:
- The described technique offers a safe and effective method for retrograde urethrography.
- This non-instrumental approach is recommended for diagnosing urethral disease.
- It is particularly beneficial when urethral manipulation is contraindicated or impossible due to meatal stenosis.
