Hysteroscopic findings in patients with post-menstrual spotting with prior cesarean section.

OBJECTIVE To identify uterine hysteroscopic findings among patients with prior cesarean section and whom had post-menstrual bleeding spotting type. METHODS We conducted a descriptive and prospective study between June 2008 and December 2009 involving women admitted to our clinic in Ji-Paraná (RO), Brazil, and who complained of prolonged genital bleeding after menstrual period. A total of 20 women with the simultaneous following characteristics were selected: at least one prior cesarean section, aged between 18 and 45 years, no use of hormonal contraceptives, and no history of uterine surgery that could change the cavity anatomy. All participants underwent a hysteroscopic examination. RESULTS During hysteroscopy, in 90% of the patients, the presence of a cesarean section scar was observed in the last third of the cervix. This scarring causes an anomaly in the uterine cavity anatomy, characterized by the viewing of an enlargement followed by a retraction of the anterior wall, which affords the presence of a pseudocavity with depth and lumen narrowing in variable degrees. Two patients did not present the pseudocavity. CONCLUSION Pseudocavities in cesarean section scar are usually found in hysteroscopic examination of patients with prior cesarean section and abnormal uterine spotting.
