Hematocolpos on Hymeneal Imperforation: A Case Report and Literature Review

Abstract

Introduction: Hymenal imperforation is a rare birth defect. It produces a vulvar obstruction responsible for vaginal retention of menstrual blood. Its diagnosis and management must be early in order to preserve the subsequent fertility of the patients. Material and Methods:We report a case of hematocolpos on hymenal imperforation hospitalized in the obstetric gynecology emergency department of the Souissi Maternity Hospital in Rabat in September 2019. The aim of our work was to analyze the diagnostic and therapeutic features of this pathology.Results and Discussion: It emerges from this work that this anomaly is the prerogative of patients in the peri-pubertal period. The spectrum of clinical signs is dominated by abdominopelvic pain, the existence of abdomino-pelvic swelling and urinary complications such as acute urine retention, pollakiuria and dysuria. The diagnosis is mainly clinical by the discovery of perineovulvar swelling on genital examination, it is guided by ultrasound. Surgical treatment is simple. It is carried over an incision of the obturating membrane and drainage of the collection. Revision surgery is necessary in the event of hymenal restenosis. Conclusion:Systematic screening for hymenal imperforation at birth and its early diagnosis in the face of painful primary amenorrhea can prevent its complications.
