Doppler Ultrasound Assisted Varicocelectomy Improve Sperm Qualities

Not Applicable

• Conditions: Varicocele

• Registration Number: NCT02695199
• Lead Sponsor: The Second Hospital of Shandong University

Brief Summary

To evaluate the benefits of laparoscopic Doppler ultrasound (LDU) assisted laparoscopic varicocelectomy (LV) and compare the surgical outcomes and complications between LDU assisted LV (LDU-LV) and microscopic subinguinal varicocelectomy for infertile patients with varicoceles.

Detailed Description

To compare the surgical outcomes such as semen parameters and the pregnancy rate and complications like postoperative varicocele recurrence and hydrocele between laparoscopic Doppler ultrasound assisted laparoscopic varicocelectomy and conventional microscopic subinguinal for infertile patients with varicoceles. To examine the microanatomy of the spermatic cord within suprainguinal portion.
