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.
