The value of compression during excretion voiding urethrography.
Voiding urethrography with compression of the urethral meatus was evaluated as part of excretory urography in patients with symptoms involving the lower urinary tract. Meatal compression permits distension of the urethra distal to any area of increased resistance to flow, obviating the need for retrograde urethrography. The examination can be performed as part of routine excretory urography and avoids the hazards of urethral catheterization. In selected patients, excretion voiding urethrography with compression has given as much information as the combination of noncompression voiding urethrography and retrograde urethrography.
