Abstract

Study Objective: Bladder involvement is rare in endometriosis. The prevalence is estimated to be ∼1% in patients with endometriosis. However, this figure seems to be an underestimation. The diagnosis of bladder endometriosis might be missed during laparoscopy. The aim of this study was to determine an intraoperative visual score of pelvic lesions that help the surgeon suspect bladder endometriosis. Design, Design Classification: A retrospective analysis was performed on the intraoperative photographs and videos of 69 patients with histological confirmation of bladder endometriosis. Setting: A tertiary referral center. Patients: Sixty-nine patients with bladder endometriosis were operated on in our center over a 9-year period. Interventions: Evaluation and analysis of intraoperative laparoscopic findings. Main Results: We found three subtypes of laparoscopic findings that can assist with diagnosing bladder endometriosis. The most prominent sign was named "kissing round ligaments" (Type K), in which the right and left round ligaments appear closer to each other than usual or even touching one another. This sign is strongly associated with full-thickness invasion of the bladder. Other laparoscopic findings that indicated bladder endometriosis were anatomical distortion (Type A) and proximal occlusion of the tubes (Type B). We further define a scoring system for the lesion that correlates with the severity of the bladder endometriosis from superficial lesions to full thickness. Conclusion: Bladder endometriosis is a rare condition and often remains undiagnosed. Indeed, even during surgery, bladder endometriosis can be missed if the operator is not aware of the suggestive signs. Operative laparoscopic findings may help the surgeon to diagnose bladder endometriosis, and these signs correlate with the severity of the disease.
