Symptoms and Surgical Technique of Bladder Endometriosis: A Systematic Review

Objective: This systematic review aimed to review all the available evidence regarding bladder endometriosis (BE) surgical techniques, resolution of symptoms, and nodule size.Data Sources: We conducted systematic searches in PubMed MEDLINE, Embase, Latin American and Caribbean Centre on Health Sciences Information, Cochrane Library, and Web of Science databases from inception to December 2021.Methods of Study Selection: Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the literature search yielded 1279 articles. Two reviewers independently screened abstracts and reviewed full-text articles to meet the eligibility criteria: women diagnosed as having BE, treated surgically to remove the BE nodule, and reported of the nodule size and/or symptoms after the surgery. We included 28 studies, which mainly were case reports and case series.Tabulation, Integration, and Results: The following information was extracted from the included studies: author, country, publication year, study design, number of patients, age, surgery performed, follow-up time, operation time, nodule location, nodule size, and postsurgical symptoms. Patients' ages range from 26 to 44 years and most women were nulliparous. The BE nodule size ranged from 0.7 to 5.5 cm, and the most frequent location (63.57%) was the posterior wall. Dysuria was reported by 27.18% of women and generic lower urinary tract symptoms were reported by 27.95%. After surgery, the recur-rence rate of urinary symptoms was 7.34%. Most studies performed a partial cystectomy to remove the nodule, showing that the disease affects the bladder mucosa frequently.Conclusion: Surgical treatment with complete excision of BE lesion was shown to improve complaints of urinary symp-toms in patients with BE. Given that most of the studies evaluated were descriptive, additional studies with a large sample population and a better level of evidence for this condition are needed.
