Dynamic Observation of the Morphological Changes in Paraurethral Ducts Infected with Gonococci in Men before and after Ceftriaxone Therapy Using High-Frequency Ultrasound

Objective
To observe the morphological changes in paraurethral ducts infected with gonococci in men before and after the administration of the ceftriaxone therapy using high-frequency ultrasound and determine its clinical significance.

Methods
Thirty-two male patients with gonococcal paraurethral duct infection were enrolled. Their lesions were examined using an ACUSON X300 ultrasound system before and after they were subjected to ceftriaxone therapy.

Results
The paraurethral duct was completely closed 3–4 days after ceftriaxone treatment in 30 patients. Paraurethral duct closure began from the blind end and proceeded gradually towards its orifice; during closure, the paraurethral duct diameter showed no apparent change. These 30 patients whose paraurethral ducts closed were considered cured. In the remaining 2 patients, the length and diameter of the paraurethral ducts showed no change before and after ceftriaxone treatment; one patient was unresponsive to ceftriaxone treatment, and the other had secondary dilatation of the paraurethral duct. These 2 patients were cured after surgery.

Conclusion
High-frequency ultrasound enables dynamic observation of the morphological changes in paraurethral ducts infected with gonococci before and after ceftriaxone therapy. High-frequency ultrasound can provide valuable information for incision, drainage, and wedge resection of paraurethral ducts.
