Methods With the aid of high?frequency ultrasound images, 11 male patients with paraurethral duct dilatation following gonococcal paraurethral duct infection were treated with wedge resection. The data were collected, including the surgical duration, amount of bleeding during the surgery, period of wound healing and complications. If the ostium beside the external urethral orifice disappeared within 4 weeks after the surgery, there was no discharge from the ostium with pressure, and no tubular echoic area was observed by high?frequency ultrasound imaging, the patient was considered to be recovered. If none of the above three conditions could be met, the surgical treatment was considered to be ineffective. Results The average surgical duration was 19.19 ± 2.71 minutes （range, 14 - 23 minutes）, the average amount of bleeding during the surgery was 11.09 ± 2.07 ml （range, 8 - 14 ml）, and the average period of wound healing was 14.91 ± 1.45 days （range, 13 - 17 days）. Of the 11 patients, 10 were cured, and 1 showed no response. No complications were observed in any of the 11 patients, and no defects formed in the glans penis. Conclusion Wedge resection is a kind of effective therapy for paraurethral duct dilatation following gonococcal paraurethral duct infection in males.
