Hulka Clip Sterilization

One common form of female sterilization is the use of Hulka clips to block the fallopian tubes. The Hulka clip was approved for use in the United States in the 1970’s and was invented in Chapel Hill, North Carolina by Dr. Jaroslav Hulka at the University of North Carolina at Chapel Hill.

The Hulka clip is a small, gold plated stainless steel spring loaded clip. The clip in introduced into the abdominal cavity via a laparoscopic clip applicator. This image shows the open clip in the applicator and the tip of the laparoscope with its fiber optic lighted end. When the clip is placed across the fallopian tube, it is closed and a small spring holds the clip firmly across the tube. The Hulka clip has the advantage of damaging only a very small portion of the fallopian tube- approximately 7mm (the thickness of three quarters stacked on each other).

The Hulka clip causes bilateral tubal occlusion by squeezing a very small portion of the tube. The squeezed portion is deprived of its blood supply and eventually undergoes avascular necrosis (dies and is absorbed by the body). This causes the fallopian tube to be divided in half and the two ends to close up. The Hulka clip is held in place between the two divided tubal segments by a small amount of scar tissue which forms within the clip.

Hulka Clip Reversal

A common misconception is that the Hulka clips can simply be opened to reverse the sterilization process - that the tubes can be unclipped. Unfortunately, tubal ligation reversal for Hulka clips is not that simple. Hulka clip tubal occlusion is reversed by removing the section of the tube with the clip across it and then, using microsurgical techniques, joining the remaining tube segments back together in perfect alignment.

Tubal reversal of Hulka clip tubal occlusion is better than for most other methods of sterilization because such a minimal amount of tube is destroyed in the occlusion process. Approximately 76% of patients at Chapel Hill Tubal Reversal Center become pregnant after a reversal of a Hulka clip sterilization procedure.

Common Misconception About Tied Tubes

Many patients seem to imagine the fallopian tube is like a shoe lace which is tied up like a bow to prevent pregnancy. As tubal ligation reversal specialists, we wish it were that easy- then untying tied tubes would be easier!

‘Tying ones fallopian tubes’ is a common language phrase used to describe several different surgical procedures which result in sterilization (a procedure intended to permanently prevent pregnancy). The more correct medical term is bilateral (both sides) tubal occlusion (closure of the fallopian tube).

There are many different ways to occlude (close) the fallopian tubes: ligation and resection (tying and cutting), clips and rings, and coagulation (burning). No matter how the procedure is done the end result causes the tube to close, heal shut, and prevent sperm from fertilizing an egg.

Tubal Sterilization is Reversible

Many people believe tubal sterilization is permanent and irreversible. Although Hulka clip sterilization is intended to be permanent, this procedure is ideal for tubal reversal. The Chapel Hill Tubal Reversal Center is the one medical facility which specializes in tubal ligation reversal.

We have become experts in reversing all types of tubal ligations- or ‘untying’ tubes that have been ‘tied’!

Past topics in the Tubal Reversal Blog include posts and comments about patient care at Chapel Hill Tubal Reversal Center. This topic summarizes important articles about tubal ligation and tubal reversal reported in the news during 2007.

Sterilization is Most Popular Family Planning Method
Approximately 10 million American women use the pill for contraception, while sterilization has been chosen by 15 million men and women.

One In Five Women Regret Decision For Tubal Ligation
One in five women under age 30 who undergo tubal sterilization later regret the procedure, despite the number of children they have.

Is Sterilization the Best Contraception Choice?
Women requesting a tubal ligation should be counseled regarding other long-term, reversible methods of contraception and informed that vasectomy is safer and more effective than tubal ligation.

Tubal Ligation Counseling Issues
Counseling about tubal ligation should include permanence of the method, possibility of future regret, and information about the specific techniques of tubal sterilization.

Relationship Conflict Before Sterilization
Women whose relationship was marked by substantial conflict before they underwent tubal ligation were most likely to regret the decision.

Young Age, Prodding Partner and Sterilization Regret
Young age and a prodding partner are risk factors indicating that a woman undergoing sterilization may later regret her decision.

Tubal Reversal Among Overweight Women
Overweight women’s chances of becoming pregnant after tubal reversal improve when they lose weight.

Dr. Berger’s Comment

These news reports touch on some of the issues patients talk about when they come to Chapel Hill Tubal Reversal Center for tubal sterilization reversal. The popularity of tubal ligation, and the fact that many women regret their decision to have a tubal ligation, are well documented. Young age and marital conflict are risk indicators for subsequent regret. Before performing a tubal ligation, doctors should ensure that the implications of ending childbearing potential are clearly understood and discuss vasectomy as an alternative permanent method of birth control. Women undergoing tubal reversal who are overweight should be aware that losing weight will improve their chances of becoming pregnant again.

Almost every article one reads about tubal ligation stresses that it is permanent. Most doctors and the lay public believe this to be true. In my experience, however, tubal ligation is reversible in over 95% cases!

Doctors stress that tubal ligation is a permanent method birth control because it cannot be discontinued easily such as stopping the use of birth control pills or the patch, removing an IUD, or avoiding the use of barriers contraceptives (condom or diaphragm). In the past, reversing a tubal ligation procedure involved complicated surgery with its attendant high cost (up to $35,000). The outpatient tubal ligation procedure that I have developed is uncomplicated surgery and avoids the expense of hospital charges. This has reduced the cost of tubal reversal surgery to under $6000. This is less than the cost of a single treatment cycle with in vitro fertilization (averaging $10,000 - $12,000). My effort over the past 3 decades has been to make tubal reversal surgery easy to undergo and affordable for couples.

There are some methods of female sterilization that are not reversible. These include complete removal of the fallopian tubes (total salpingectomy) and extremely destructive methods of partial salpingectomy that do not leave two segments to repair. An example of the latter is when only a short portion of the tube is attached to the uterus and the remaining segment contains only fimbrial tissue with no tubal muscle or opening. In this case, the fimbrial tissue alone cannot be rejoined successfully to the uterine segment of tube. Fortunately, this is an unusual occurrence. In cases where there is a sufficient length of tube attached to the uterus, it can be opened and be able function normally even without the fimbrial end. This is called ampullary salpingostomy. This technique is useful in reversing a fimbriectomy (removal of the fimbrial or ovarian end of the fallopian tube).

Reviewing the operative report from a tubal ligation procedure usually will indicate how destructive the procedure was. When there is a question about this, diagnostic laparoscopy can be performed to examine what remains of the fallopian tubes. If there are sufficient segments to repair, tubal reversal can be done right then while the patient is under anesthesia.

The best method of tubal ligation to reverse is the clip procedure. The Hulka Clip was developed in the 1970s by Dr. Jaroslav Hulka, a professor of obstetrics and gynecology at the University of North Carolina at Chapel Hill. (Dr. Hulka was one of my most influential teachers during my residency in ob-gyn at UNC.) The tubal ring also is an excellent method for reversing. The clip and ring procedures tend to damage the least amount of the fallopian tube and leave behind long segments to repair.

The most common tubal ligation procedures involves tying and cutting the tubes (ligation/resection) or burning the tubes (coagulation). Experience shows that 98% of these procedures are reversible.

Summary: Tubal ligation is not really permanent in the sense that it can be reversed in almost all cases. This is fortunate for those women who want another chance to have a baby after having their tubes tied. Tubal reversal is more successful, less complicated, and less expensive than the alternative treatment of in vitro fertilization.
