Microsurgical denervation of the spermatic cord for treatment of idiopathic chronic orchialgia / 中华医学杂志(英文版)

A patient referred to our hospital, diagnosed with left idiopathic chronic orchialgia, was evaluated with a thorough medical and psychiatric history, physical examination, scrotal ultrasound and magnetic resonance imaging. Conservative management failed. The patient had temporary pain relief after undergoing outpatient cord block three times. Microsurgical denervation of the left spermatic cord was operated in March, 2011. A pain questionnaire was used to determine efficacy before and after operation, and complete pain relief was noted at one week after operation. The follow up period was 12 months, at the end of which the pain score was still zero. No complications, including testicular atrophy and hydrocele, occurred. Microsurgical denervation of the spermatic cord can be a minimally invasive, safe and effective management option for treatment of idiopathic chronic orchialgia.

Surgical treatment of obstructive azoospermia: a report of 56 cases / 中华男科学杂志

<p><b>OBJECTIVE</b>To evaluate the diagnosis and surgical treatment of obstructive azoospermia.</p><p><b>METHODS</b>We analyzed the clinical data of 56 cases of obstructive azoospermia, 43 of them with ejaculatory duct obstruction (EDO), and the other 13 suspected of epididymal obstruction. The diagnostic methods included semen analyses, measurement of fructose and neutral alpha-glucosidase in the seminal plasma, transrectal ultrasonography (TRUS), and vasography when necessary. The 43 patients with EDO were treated by transurethral resection of the ejaculatory duct (TURED), and 11 of the 13 cases of suspected epididymal obstruction were confirmed by scrotal exploration and underwent either bilateral or unilateral vasoepididymostomy. The patients were followed up for 3 -51 months for postoperative semen quality and impregnation.</p><p><b>RESULTS</b>Of the 43 azoospermia patients with EDO treated by TURED, 36 (83.7%) showed improved semen parameters and 11 (25.6%) achieved pregnancies. Among the 11 cases of azoospermia with confirmed epididymal obstruction treated by vasoepididymostomy, 6 (54.5%) had sperm in the semen assay and 3 (27.3%) achieved pregnancies.</p><p><b>CONCLUSION</b>Semen analyses, measurement of fructose and neutral alpha-glucosidase in the seminal plasma, TRUS and vasography are important diagnostic methods for obstructive azoospermia. TURED is effective for azoospermia with EDO, while vasoepididymostomy is preferable for the treatment of azoospermia with epididymal obstruction.</p>

Diagnosis and treatment of iatrogenic ejaculatory duct obstruction following prostatic hyperthermia (report of 3 cases) / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the characteristics of diagnosis and treatment of iatrogenic ejaculatory duct obstruction following prostatic hyperthermia.</p><p><b>METHODS</b>Retrospective analyses were made of the clinical data of 3 cases of ejaculatory duct obstruction following prostatic hyperthermia.</p><p><b>RESULTS</b>The 3 cases were diagnosed as urethrostenosis and deformity of the posterior urethra by transurethral ultrasound and semen analysis. And all the 3 patients had undergone prostatic hyperthermia for prostatitis. Transurethral resection of the ejaculatory duct (TURED) was performed to remove the obstruction and the postoperative semen analysis showed both semen volume and sperm count to be normal.</p><p><b>CONCLUSION</b>Urethra microwave thermotherapy, urethra radiofrequency, or per urethra rheophore ablation can be adopted in the treatment of protatitis, but should be strictly indicated and cautiously selected lest secondary iatrogenic ejaculatory duct obstruction should result. For the treatment of this obstruction, TURED is the first choice.</p>
