This video, titled "Hysteroscopic Tubal Catheterization Combined with Flushing Technique – Insights from WALS 2025," presents a breakthrough, minimally invasive fertility-enhancing procedure showcased at the World Association of Laparoscopic Surgeons (WALS) 2025 conference. Highlighting both innovation and simplicity, this technique has gained attention for its ability to restore tubal patency in women with proximal tubal obstruction—a major cause of infertility.

What is Hysteroscopic Tubal Catheterization with Flushing?

The procedure involves the use of a rigid or flexible hysteroscope, through which a tubal catheter is introduced under direct vision to access the uterotubal junction. Once positioned, gentle flushing is performed using saline or methylene blue dye to relieve spasm, dislodge minor debris, or open functional blockages. In many cases, this flushing restores natural tubal patency and improves chances of spontaneous conception.

Key Insights from WALS 2025 (Demonstrated in the Video)

Clinical Indication

Primarily indicated in cases of unilateral or bilateral proximal tubal occlusion, especially when diagnosed via HSG (hysterosalpingography) or sono-HSG.

Step-by-Step Procedure

The video explains:

Patient positioning and cervical access
Insertion of the hysteroscope into the uterine cavity
Identification of the tubal ostia

Introduction of the tubal cannulation catheter

Controlled flushing with distension media or contrast agent

Safety and Precision

The technique is performed under direct hysteroscopic vision, avoiding blind manipulations and reducing the risk of tubal trauma or perforation. The session at WALS emphasized fluoroscopy-free practice, making it suitable for office settings.

Outcomes and Benefits

Experts at WALS 2025 shared evidence showing:
Up to 70–80% restoration of tubal patency
Increased spontaneous pregnancy rates
Avoidance of unnecessary laparoscopic tuboplasty or IVF
Minimal patient discomfort and recovery time

Advantages Over Traditional Methods

Office-based, no general anesthesia required
Diagnostic and therapeutic in one sitting
Cost-effective compared to IVF or laparoscopy
Enhances natural conception in select patients
Reduces emotional and financial burden on couples

Conclusion
The hysteroscopic tubal catheterization with flushing technique, as presented at WALS 2025, marks a major advancement in reproductive endoscopy. Combining diagnostic precision with therapeutic potential, this simple yet powerful approach empowers gynecologists to offer minimally invasive infertility management with excellent outcomes. The video offers a step-by-step visual demonstration along with expert commentary, making it an essential resource for reproductive surgeons and endoscopic specialists.
