Falope Ring Sterilization

The Yoon Falope rings were developed in the 1960’s as a safer alternative to laparoscopic monopolar cautery tubal sterilization. This procedure is performed by inserting a laparoscope just under the belly button. The fallopian tube is then identified and a device holds the tube while the silastic ring is slid over a 2-3 cm ’knuckle’ of tube that is kinked off by the ring. This is done once for each side.

The common misperception is that the Falope ring is what prevents pregnancy and that reversal of the procedure simply requires removal of the ring. The Falope ring causes the squeezed ’knuckle’ of tube to undergo avascular necrosis (to die and become absorbed by the body). After this happens the ends of the tubal segments outside the ring close up, thereby preventing sperm from reaching the egg.

Falope Ring Sterilization Reversal

Reversing Falope ring sterilization is not as easy as just removing the ring. The closed ends of the tubes must be opened and the tubal segments must be rejoined.

Falope rings cause destruction of a minimal length of fallopian tube and reversal of this type of tubal ligation gives excellent results. Approximately 75% of patients at Chapel Hill Tubal Reversal Center become pregnant after a reversal of a Falope ring sterilization procedure.

Many people believe tubal sterilization is permanent and irreversible. Although tubal sterilization with Falope rings is intended to be permanent, this procedure can be reversed. Chapel Hill Tubal Reversal Center is the only medical facility that specializes exclusively in reversal of tubal ligation.

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 as simple as opening the clips. 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.

Filshie Clip Tubal Ligation

One common form of laparoscopic (camera) sterilization is the use of Filshie clips to occlude both fallopian tubes. The Filshie clip was approved for use in the United States in the mid 1990’s. The Filshie clip is a small titanium clip which is lined with a thin silicone cushion. The clip was an improvement over the Yoon Falope Ring and the Hulka Clip because it was as easy to apply with less risk of operative complications. The clip also has the advantage of destroying only a very small portion of the fallopian tube- approximately 4mm (approximately the thickness of two quarters stacked on each other). The adjacent tube is not affected. The majority of Filshie clips placed in the United States are done by laparoscopic surgery; however, there is a growing trend to use them for tubal occlusion at the time of cesarean delivery (c-section).

The Filshie 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 Filshie clip is held in place (in between the two divided ends) by a small amount of scar tissue which forms over the clip.

A common misconception is that the Filshie clips can simply be removed to reverse the sterilization process- that the tubes can be unclipped. Unfortunately, tubal ligation reversal for Filshie clips is not as simple as just opening the clips. Filshie clip tubal occlusion is reversed by removing the clips and using microsurgical techniques to open the closed ends and join the tubal segments back together in perfect alignment.

The reversal of Filshie clip tubal occlusion is usually technically easier than some 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 Filshie clip sterilization procedure.

Tubal Sterilization Can Be Reversed

Many people believe tubal sterilization is permanent and irreversible. Although Filshie clip sterilization is intended to be permanent, this procedure can be reversed. Chapel Hill Tubal Reversal Center is the one medical facility that specializes in tubal ligation reversal.

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.

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.
