Introduction

Total Laparoscopic Hysterectomy (TLH) has transformed the field of gynecologic surgery by offering patients a minimally invasive alternative to traditional open hysterectomy. The procedure provides numerous benefits including reduced postoperative pain, shorter hospital stay, minimal blood loss, faster recovery, and improved cosmetic outcomes. As laparoscopic techniques continue to evolve, surgeons are constantly seeking methods that further improve surgical precision and patient safety.

One of the major concerns during hysterectomy procedures is the risk of ureteric injury. The ureters lie in close proximity to the uterine arteries and cervix, making them vulnerable during dissection and energy application. To minimize this risk, the use of infrared ureteric catheters has emerged as an innovative advancement in laparoscopic gynecologic surgery.

The combination of a three-port TLH approach with infrared ureteric catheter guidance represents a modern surgical strategy that enhances visualization while reducing surgical invasiveness. This technique allows surgeons to identify the ureters in real-time using infrared imaging, significantly improving operative safety during difficult pelvic dissections.

Understanding Total Laparoscopic Hysterectomy

Total Laparoscopic Hysterectomy involves the complete removal of the uterus, including the cervix, through laparoscopic techniques. The surgery is performed using specialized instruments inserted through small abdominal ports. Traditionally, TLH may require four or more ports; however, advances in instrumentation and surgeon expertise have enabled successful procedures using only three ports.

Common Indications for TLH

TLH is commonly performed for:

• Symptomatic uterine fibroids
• Adenomyosis
• Abnormal uterine bleeding
• Endometriosis
• Chronic pelvic pain
• Premalignant gynecological conditions
• Early-stage gynecologic cancers

The minimally invasive nature of TLH offers significant advantages over abdominal hysterectomy, especially in terms of postoperative recovery and patient satisfaction.

Evolution of the Three-Port Technique

Conventional laparoscopic hysterectomy generally involves multiple abdominal ports to facilitate visualization and instrument manipulation. However, reducing the number of ports has become an important goal in minimally invasive surgery.

The three-port technique typically includes:

• One umbilical camera port
• Two accessory working ports

This approach minimizes abdominal wall trauma while maintaining adequate ergonomics for safe dissection and suturing. Reduced port surgery improves cosmetic outcomes and may decrease postoperative discomfort and port-related complications.

Despite these advantages, reduced-port surgery can present challenges in complex pelvic anatomy where visualization of vital structures such as the ureters becomes critically important.

Importance of Ureteric Safety in Hysterectomy

Ureteric injury is one of the most feared complications of hysterectomy. The risk increases in cases involving:

• Large fibroids
• Severe endometriosis
• Previous pelvic surgery
• Pelvic adhesions
• Distorted anatomy
• Malignancy

Undetected ureteric injuries can result in severe complications including urinary fistula, ureteral obstruction, renal damage, sepsis, and the need for reconstructive surgery.

Therefore, reliable intraoperative identification of the ureters is essential to prevent complications and improve surgical outcomes.

Role of Infrared Ureteric Catheters

Infrared ureteric catheters are specially designed devices that emit fluorescence or infrared signals visible through near-infrared laparoscopic imaging systems. Once inserted into the ureters cystoscopically before surgery, these catheters allow continuous visualization of the ureteric pathway throughout the operation.

Advantages of Infrared Ureteric Catheters

• Real-time ureter identification
• Enhanced safety during difficult dissection
• Reduced risk of ureteric injury
• Better visualization in distorted pelvic anatomy
• Increased surgeon confidence
• Improved precision during energy application

The technology is especially beneficial in advanced laparoscopic procedures where tissue planes are obscured by fibrosis or adhesions.

Surgical Technique

Preoperative Preparation

Patients undergo standard preoperative evaluation including:

• Pelvic imaging
• Routine blood investigations
• Anesthesia fitness assessment
• Informed consent

Under anesthesia, cystoscopy is performed, and infrared ureteric catheters are inserted bilaterally into the ureters.

Port Placement

The three-port setup usually includes:

1. A 10 mm umbilical camera port
2. A 5 mm left lower quadrant working port
3. A 5 mm right lower quadrant working port

The laparoscope equipped with near-infrared imaging capability allows visualization of the glowing ureteric catheters throughout the procedure.

Operative Steps

The surgery proceeds in a systematic manner:

• Inspection of the abdominal cavity
• Identification of pelvic anatomy
• Coagulation and division of round ligaments
• Development of bladder flap
• Skeletonization and sealing of uterine vessels
• Circumferential colpotomy
• Removal of uterus vaginally
• Closure of vaginal vault laparoscopically

During critical dissection near the uterine arteries and cardinal ligaments, the infrared ureteric catheters clearly delineate the ureters, reducing the possibility of accidental injury.

Clinical Advantages of the Combined Approach

The integration of infrared ureteric guidance with three-port TLH provides several clinical benefits.

Enhanced Surgical Precision

Continuous ureter visualization improves accuracy during dissection and energy application.

Reduced Complication Rates

The ability to identify ureters in real-time lowers the risk of thermal or transection injuries.

Better Cosmetic Results

Fewer ports result in smaller scars and improved patient satisfaction.

Faster Recovery

Patients experience less postoperative pain and quicker return to normal activities.

Improved Outcomes in Complex Cases

The technique is particularly valuable in patients with severe adhesions, endometriosis, obesity, or previous pelvic surgeries.

Challenges and Limitations

Although highly promising, the procedure has certain limitations:

• Requirement for specialized infrared imaging equipment
• Additional cost of ureteric catheters
• Learning curve for surgeons
• Need for cystoscopic expertise
• Limited availability in some centers

However, the long-term benefits of reducing ureteric injuries may outweigh the additional procedural costs.

Future Perspectives

The future of minimally invasive gynecologic surgery lies in enhanced imaging technologies and precision-guided procedures. Infrared fluorescence-guided surgery is expected to become increasingly common as equipment becomes more accessible and cost-effective.

Combining reduced-port laparoscopy with image-guided navigation represents an important step toward safer and smarter surgery. Future developments may include artificial intelligence-assisted imaging, robotic integration, and advanced fluorescence mapping techniques.

Conclusion

Three-Port Total Laparoscopic Hysterectomy with Infrared Ureteric Catheter guidance is an innovative advancement in minimally invasive gynecologic surgery. By combining reduced-port access with real-time ureter visualization, this technique enhances surgical safety, precision, and patient outcomes.

The approach is particularly valuable in complex pelvic surgeries where ureteric identification is challenging. As laparoscopic technology continues to evolve, infrared-guided surgery may become a standard adjunct for preventing ureteric complications during hysterectomy procedures.

This modern surgical strategy reflects the ongoing commitment of minimally invasive surgeons to achieve safer operations, faster recovery, and superior patient care through technological innovation.
