[Descending urethrography in men with low urine flow]

Area of Science:

• Urology
• Medical Imaging
• Radiology

Background:

• Mixed cystourethrography is a diagnostic imaging technique used to visualize the urethra and bladder.
• Patients with low urinary flow rates present challenges for obtaining adequate urethral distension during imaging.
• Venous refluxes can complicate imaging and obscure important anatomical details.

Observation:

• A novel shuttering method was developed for mixed cystourethrography.
• This technique allows temporary cessation of urination, facilitating urethral filling without overdistension.
• The method was applied to patients experiencing low volumetric rates of urination.

Findings:

• The shuttering method was tested in 29 patients with urethral and urocyst neck stenosis.
• Clear visualization of the urethra distal to strictures was achieved.
• Accurate measurement of urethral length and diameter below the stricture was possible.

Implications:

• This technique offers an improved approach for evaluating urethral strictures in patients with impaired urinary flow.
• It enhances diagnostic accuracy by preventing overload and venous refluxes.
• The method provides valuable data for surgical planning and patient management.
