case_images: Lateral (A) and sagittal (B) plane MRI: T2 WI mode; soft tissue in the pelvis. Retrograde urethrogram (C): two paraurethral cavities in the bulbar area contrasted. (1) Urethra, (2) left chamber CS, (3) right chamber CS, and (4) Cowper's duct.

case_images: In retrograde urethrography, the cavities were contrasted from the urethral lumen, with the contrast agent thrown into the duct of the bulbourethral gland (Figure 1).
case_images: Hole in the left CS chamber (A), hole in the inter-chamber septum, through which the right CS was opened (B), and right (C) and left (D) CS chamber with gaping ducts of bulbourethral glands. (1) CS roof, (2) left CS hole, opening into the urethral lumen, (3) left CS chamber, (4) right CS chamber, (5) septum between the right and the left CSs, (6) duct of the right Cowper's gland, and (7) duct of the left Cowper's gland.

case_images: Urethroscopy revealed an opening at 6 o'clock on the conditional clock leading into the left CS, with the right chamber opening into it through the common medial wall, and an examination of the chambers proximally revealed dilated ducts of the right and left bulbourethral glands (Figure 2).
case_images: Removal of the septum between the cavities (A), postoperative view (B); microscope slide: hematoxylin-eosin staining, 20x, lined with prismatic epithelium (C); microscope slide: hematoxylin-eosin staining, 9.5x, the wall of the cyst is formed by fibrous tissue, with a large cistern of blood vessels of varying caliber and blood filling (D). (1) Bottom of the right CS chamber, (2) bottom of the left CS chamber, (3) edge of anterior wall resection, (4) edge of septal resection, (5) duct of the left Cowper's gland, (6) prismatic epithelium, (7) fibrous tissue, and (8) blood vessels.

case_images: As a result, a wide connection to the lumen of the urethra was achieved (Figure 3). An examination of the dissected CS walls showed that they contained edematous fibrous tissue, and the lining was composed of prismatic epithelium (Figure 3).
case_images: Retrograde urethrogram with tight urethral filling (A), contrast reflux into the bulbourethral duct is contrasted; after emptying, the urethra contains a small amount of remaining contrast (B); urethroscopy: back of CS chambers connected to the urethral lumen (C) and gaping of the left bulbourethral duct is visible (D). (1) Contrasted duct of the Cowper's gland, (2) duct of the left Cowper's gland, and (3) duct of the right Cowper's gland.

case_images: The left bulbourethral duct retained a partial gaping (Figure 4).
