Scope of Experience

I practice medical and surgical treatment for infertility, as well as the laboratory part of IVF/ICSI.

My field of special interest is microsurgery; for correction of obstruction, varicocelectomy and microdissection TESE.

My approach to the repair of seminal tract obstruction is to perform a full repair to all sites of obstruction on either side in the same setting. This may involve epididymovasostomy, vasovasostomy, transurethral resection of the ejaculatory ducts, pelviscrotal vasovasostomy, or a combination of the aforementioned, since I have come to believe that multiple site obstruction is a common incident. I have published this approach at the PAMJ:

Pelviscrotal Vasovasostomy

Pelviscrotal Vasovasostomy "PSVV" is a technique I invented to bypass obstruction at the inguinal region as a result of previous inguinal surgery. Classically, this used to be approached by ICSI or inguinal vasovasostomy that involves a large incision on each side of the abdomen on top of the previous large incisions of the hernia repair, and to try the impossible process of finding and re-attaching the remnants of the vas deferens within the chaotic site of the previous surgery.

In 2004, I proposed for the first time my surgical technique: “Pelvi-scrotal vasovasostomy”, where the natural reserve of the vas deferens that is found deep in the pelvis is utilized to go straight to the testis bypassing the site of obstruction. This was achieved through very small incisions, a virtue of laparoscopy.

This technique was published in the German “Andrologia” and the American “Journal of Urology”

The vas deferens is dissected and rendered intraperitoneal

The vas is cut off the internal inguinal ring and pulled out of the pelvis through the external inguinal ring, thus retrieving the length seen in the picture outside.
