A total of 191 patients were evaluated at our department for azoospermia, and 11 were found to have azoospermia due to ejaculatory duct obstruction as proved by normal serum hormones, normal testicular biopsy, low ejaculate volume and absence of fructose in semen. Also transrectal ultrasound was performed, revealing distended seminal vesicles and dilated ejaculatory ducts. All these criteria together suggested ejaculatory duct obstruction as a cause of azoospermia. All patients underwent endoscopic management for treatment of their ejaculatory duct obstruction in the form of resection and/or incision of the ejaculatory duct ostium inside the urethra and patency was checked intraoperatively by injection of sterile methylene blue in the vas and visualizing the efflux of the blue dye endoscopically. Intraoperative patency was documented in 10 patients and postoperative patency by follow-up semen analysis in 7 patients (70% patency rate) of which 2 (20% pregnancy rate) were able to conceive within 2 years of endoscopic treatment. Postoperative complications included acute urinary retention in 1 patient, haematuria in 5 and recurrent epididymitis in 2 patients.
我院男科共评估了191例无精子症患者,其中11例经检查确诊为因射精管梗阻导致的无精子症,其血清激素水平正常、睾丸活检正常、射精量少且精液中无果糖。同时进行了经直肠超声检查,结果显示精囊扩张、射精管增宽。综合各项标准,提示射精管梗阻是导致无精子症的原因。所有患者均接受了内镜治疗,通过切除和/或切开尿道内的射精管口来治疗射精管梗阻,并在术中通过向输精管内注射无菌美蓝并在内镜下观察蓝色染料的流出情况来检查通畅性。术中记录了10例患者的通畅情况,术后通过精液分析随访记录了7例患者的通畅情况(通畅率为70%),其中2例(妊娠率为20%)在内镜治疗后2年内成功受孕。术后并发症包括1例急性尿潴留、5例血尿和2例复发性附睾炎。
