This video on Laparoscopic Management of Bladder Endometrioma provides a detailed surgical overview of the diagnosis, preoperative evaluation, and minimally invasive treatment of bladder endometriosis. The video demonstrates step-by-step laparoscopic techniques, including safe bladder dissection, excision of endometriotic lesions, and reconstruction, ensuring optimal functional and reproductive outcomes.

Ideal for gynecologists, laparoscopic surgeons, and postgraduate trainees, this educational video highlights key anatomical landmarks, surgical tips, and strategies to minimize complications. Watch this expert-led video to enhance your understanding of advanced laparoscopic management of complex endometriosis cases.

An optimal treatment of bladder and urethral endometriosis should ideally involve a team of experts, ie, gynecologic endoscopists, radiologists, and urologists, who are familiar with endometriosis. Endometriosis means presence of endometrium outside the uterus. Pelvic surgeries such as caesarean section, tubal ligation, hysterotomy, laparotomy for ectopic pregnancy and hysterectomy lead to implantation of endometrium in skin, subcutaneous tissue, sheath, rectus muscles, vesicovaginal septum and in uterine scar . Involvement of decidua in uterine scar grows as bladder endometriosis. This supports the migratory or metastatic theory of implantation of endometriosis. Involvement of decidua in uterine scar grows as bladder endometriosis. Most commonly it affects organs such as the ovaries, uterine ligaments, fallopian tubes, rectum and the cervico-vaginal region. Involvement of the urinary tract, is seen in just about 1% cases. Bladder is involved in 84% cases. Patients underwent coagulation of the endometriotic foci over the uterovesical peritoneum.

Endometriosis is a chronic gynecological condition characterized by the presence of endometrial tissue outside the uterine cavity. Although it most commonly affects the ovaries, pelvic peritoneum, and uterosacral ligaments, involvement of the urinary tract is rare, occurring in approximately 1–2% of cases. Among urinary tract endometriosis, the bladder is the most frequently affected organ. A bladder endometrioma can lead to significant morbidity if not diagnosed and managed appropriately. Laparoscopic surgery has emerged as the gold standard for the effective management of bladder endometrioma due to its precision, safety, and excellent clinical outcomes.

Pathophysiology of Bladder Endometrioma

Bladder endometrioma results from the infiltration of endometrial tissue into the detrusor muscle or bladder serosa. The exact mechanism remains unclear, but theories include retrograde menstruation, metaplasia of Müllerian remnants, and iatrogenic implantation during previous pelvic surgeries, particularly cesarean sections. Progressive infiltration may cause fibrosis, scarring, and distortion of normal bladder anatomy.

Clinical Presentation

Patients with bladder endometrioma often present with cyclical urinary symptoms that worsen during menstruation. Common clinical features include:

Dysuria and urinary frequency

Cyclical hematuria (pathognomonic but uncommon)

Suprapubic pain

Dyspareunia

Chronic pelvic pain

Due to overlapping symptoms with other urinary conditions, a high index of clinical suspicion is required for accurate diagnosis.

Diagnostic Evaluation

Accurate diagnosis involves a combination of clinical assessment and imaging studies:

Ultrasonography (USG): May reveal a hypoechoic mass on the bladder wall.

Magnetic Resonance Imaging (MRI): The most sensitive imaging modality, helpful in defining lesion size, depth of infiltration, and involvement of adjacent structures.

Cystoscopy: Allows direct visualization of bluish or nodular lesions within the bladder mucosa and aids in surgical planning.

Histopathology: Confirms the diagnosis by identifying endometrial glands and stroma.

Indications for Laparoscopic Surgery

Laparoscopic management is indicated in:

Symptomatic bladder endometrioma refractory to medical therapy

Progressive disease with deep bladder infiltration

Associated pelvic endometriosis requiring surgical treatment

Complications such as hydronephrosis or recurrent urinary symptoms

Laparoscopic Surgical Technique

Laparoscopic excision of bladder endometrioma requires advanced surgical expertise and meticulous dissection.

Key Steps Include:

Patient Positioning and Port Placement: Standard lithotomy with Trendelenburg position.

Exploration of Pelvis: Identification of associated endometriotic lesions.

Bladder Mobilization: Dissection of the vesicouterine space to expose the lesion.

Excision of Endometriotic Nodule: Complete resection of the affected bladder wall, ensuring disease-free margins.

Bladder Repair: Two-layer laparoscopic suturing using absorbable sutures.

Leak Test: Performed by filling the bladder with saline or methylene blue.

Foley Catheter Placement: Maintained for 7–14 days to ensure proper healing.

Partial cystectomy may be required in cases of deep muscular invasion.

Postoperative Care and Follow-Up

Postoperative management includes:

Antibiotic prophylaxis

Continuous bladder drainage

Pain management

Gradual resumption of normal activities

Follow-up imaging or cystoscopy may be recommended in selected cases. Hormonal therapy may be considered postoperatively to reduce recurrence risk.

Advantages of Laparoscopic Management

Superior visualization and precision

Reduced blood loss

Minimal postoperative pain

Faster recovery and shorter hospital stay

Preservation of bladder function

Excellent long-term symptom relief

Complications

Although uncommon, potential complications include:

Urinary fistula

Bladder leak

Infection

Recurrence of endometriosis

These risks are minimized when surgery is performed by experienced laparoscopic surgeons.

Conclusion

Laparoscopic management of bladder endometrioma is a safe, effective, and minimally invasive approach that offers excellent clinical outcomes when performed by skilled surgeons. Early diagnosis, appropriate patient selection, and meticulous surgical technique are essential for optimal results. With advancements in laparoscopic and robotic surgery, management of deep infiltrating endometriosis involving the bladder continues to evolve, offering renewed hope for improved quality of life in affected women.
