Vasectomy reversal: a clinical update.

Asian J Androl 2016 May-Jun;18(3):365-71

Department of Urology, University of Virginia, Charlottesville, VA 22908-0422, USA.

Vasectomy is a safe and effective method of contraception used by 42-60 million men worldwide. Approximately 3%-6% of men opt for a vasectomy reversal due to the death of a child or divorce and remarriage, change in financial situation, desire for more children within the same marriage, or to alleviate the dreaded postvasectomy pain syndrome. Unlike vasectomy, vasectomy reversal is a much more technically challenging procedure that is performed only by a minority of urologists and places a larger financial strain on the patient since it is usually not covered by insurance.

Pre-operative risk factors associated with need for vasoepididymostomy at the time of vasectomy reversal.

Andrology 2016 Jan 11;4(1):160-2. Epub 2015 Dec 11.

Department of Urology, Oregon Health & Sciences University, Portland, OR, USA.

The absence of sperm in the ejaculate after vasectomy reversal is commonly caused by failure to recognize and subsequently bypass epididymal or proximal vasal obstruction at the time of vasectomy reversal. If intra-operative proximal obstruction is suspected, vasoepididymostomy (VE) is recommended rather than vasovasostomy (VV). We sought to calculate the associated risk of needing VE, rather than VV with time from original vasectomy (obstructive interval) using a large cohort of vasectomy reversal patients. Read More

MRI of the epididymis: can the outcome of vasectomy reversal be predicted preoperatively?

AJR Am J Roentgenol 2014 Jul;203(1):91-8

1 Department of Radiology, University of California, San Diego, San Diego, CA 92161.

Objective: The purpose of this study is to describe the MRI findings seen with tubular ectasia of the epididymis and investigate whether MRI may predict vasal/epididymal tubular occlusion before vasectomy reversal.

Materials And Methods: First, we compared epididymal T1 signal intensity (measured as percentage change relative to ipsilateral testis) in 24 patients with sonographically established tubular ectasia compared with 22 control patients (sonographically normal epididymides). Second, in a subset of patients with tubular ectasia who subsequently underwent surgery to restore fertility (n = 10), we examined the relationship between epididymal T1 signal intensity and surgical outcome.

Obstructive azoospermia.

Urol Clin North Am 2014 Feb 15;41(1):83-95. Epub 2013 Oct 15.

Center for Male Reproductive Medicine and Surgery, Department of Urology and Institute for Reproductive Medicine, Weill Cornell Medical College of Cornell University, 525 East 68th Street, Starr 9, New York, NY 10065, USA.

Obstructive azoospermia accounts for 40% of azoospermia and results from obstruction of the excurrent ducts (due to many causes) at any location between the rete testis and the ejaculatory ducts. The diagnosis of obstructive azoospermia (OA) requires a stepwise approach to differentiate it from nonobstructive OA and to formulate management options. Localization of the site of obstruction relies on history, physical examination, and possibly laboratory, genetic, imaging tests, and intraoperative findings. Read More

Increased follicle-stimulating hormone is associated with higher assisted reproduction use after vasectomy reversal.

J Urol 2011 Jun 17;185(6):2266-71. Epub 2011 Apr 17.

Center for Male Reproductive Medicine, Department of Urology and Institute for Reproductive Medicine, Weill Cornell Medical College, New York, New York, USA.

Purpose: Of men with vasectomy 6% elect to have more children. When considering vasectomy reversal vs in vitro fertilization/intracytoplasmic sperm injection, an elucidation of preoperative factors that predict surgical success would help determine appropriate management. We tested the hypothesis that preoperative follicle-stimulating hormone 10 U/l or greater predict a lower paternity rate after vasectomy reversal. Read More

"4 × 4 vasovasostomy": A simplified technique for vasectomy reversal.

Indian J Urol 2010 Jul;26(3):350-2

Department of Urology, All India Institute of Medical Sciences, New Delhi, India.

Objectives: An ideal vasovasostomy procedure requires precise mucosal approximation with a watertight anastomosis. The standard two-layer microdot technique requires multiple sutures within each layer and is a technically difficult operation to perform. We describe a two-layered technique which adheres to the principles of tubular anastomosis, but is simpler and provides excellent results. Read More

History of vasectomy reversal.

Urol Clin North Am 2009 Aug;36(3):359-73

Department of Urology, Cornell Institute for Reproductive Medicine, New York-Presbyterian Hospital/Weill Cornell Medical Center, Weill Cornell Medical College, Box 580, 525 East 68th Street, New York, NY 10065, USA.

Vasectomy reversal has come a long way since the first anastomosis of the vas deferens and epididymis. Although its history is not as politically charged as that of vasectomy, the progress of reversal surgery has had its share of brilliant discoveries and missteps. In the early part of the twentieth century, vasovasostomy and vasoepididymostomy were esoteric procedures, but by the 1970s, a majority of urologists had some experience with reversal surgery.

Clinical observation of loupe-assisted intussusception vasoepididymostomy in the treatment of obstructive azoospermia (analysis of 49 case reports).

Asian J Androl 2009 Mar 16;11(2):193-9. Epub 2009 Feb 16.

Department of Urology, People's Hospital, Beijing University, Beijing 100044, China.

To evaluate the clinical outcomes of loupe-assisted intussusception vasoepididymostomy (VE) in the treatment of epididymal obstructive azoospermia (EOA), we retrospectively analyzed data from 49 patients with EOA who underwent two-suture longitudinal intussusception vasoepididymostomy (LIVE) between 2000 and 2007. The data included the surgical method, postoperative motile sperm count per ejaculation, percentage of progressive motile sperm and patency and pregnancy outcomes. There were a total of 49 men undergoing scrotal exploration, and epididymal obstruction was found in all cases. Read More

Division of Urology, Department of Surgery, University of Alabama at Birmingham, 1530 Third Avenue South, FOT 1105, Birmingham, AL 35294-3411, USA.

Microsurgical reconstruction to correct male infertility, although usually performed for vasectomy reversal, also is performed to correct other types of iatrogenic, congenital, and postinflammatory obstruction. In an effort to improve success rates and facilitate performance of these complex microsurgical procedures, modifications are continually suggested. This article reviews some of these proposed modifications. Read More

Results of vasovasostomy or vasoepididymostomy after failed percutaneous epididymal sperm aspirations.

J Urol 2008 Apr 4;179(4):1506-9. Epub 2008 Mar 4.

Robert Wood Johnson Medical School at Camden, Camden, New Jersey 08103, USA.

Purpose: After undergoing vasectomy approximately 4% to 6% of men change their minds and desire more children. In the past they had 2 options: 1) vasectomy reversal and 2) sperm retrieval and intracytoplasmic sperm injection. However, in our practices we began to receive requests for another option: reconstructive microsurgery after failed percutaneous epididymal sperm aspiration. Read More

E Amar

J Gynecol Obstet Biol Reprod (Paris) 2007 Dec;36 Suppl 3:S96-100

Chirurgien uro-andrologue, hôpital américain, centre de la Muette, CHU Bichat, Paris, France.

An oral assessment and thorough clinical examination are an essential prerequisite in the presence of azoospermia (varicocele? absence of vas deferens?). Examination of the volume and pH of the ejaculate must also be included in the assessment, together with measurement of the FSH and testosterone required and a scrotal and prostatic endorectal ultrasound (particularly helpful in the diagnosis of obstructions, testicular nodules etc.).

Innovative single-armed suture technique for microsurgical vasoepididymostomy.

Urology 2007 Apr;69(4):800-4

Department of Urology, Cornell Institute for Reproductive Medicine, Weill Medical College of Cornell University, New York, NY 10021-4873, USA.

Objectives: Vasoepididymostomy outcomes are heavily dependent on the surgeon's microsurgical experience and skill. To avoid back-walling the tubular lumen, the needles are generally placed inside-out through the vasal lumen using double-armed microsutures. These double-armed sutures for infertility microsurgery are very expensive and may be difficult to obtain. Read More
