RESUMO
Post tubal ligation syndrome [PTLS] is a term used to describe a variety of post tubal ligation side effects or symptoms. These include increased menstrual bleeding and hysterectomy. Whether or not post tubal syndrome is a real entity, it has been a subject of controversy in the medical literature for decades. Numerous studies have reported conflicting conclusions about these symptoms. In this study the incidence of hysterectomy for bleeding disorders among sterilized women was compared with the incidence of hysterectomy for bleeding disorders among non-sterilized female population of the same age. This study was carried out on 160 women, 38-52 years, who underwent hysterectomy in Amir University Hospital, Semnan, Iran, from September 2008 to September 2011. After gathering of data from medical records, in this study, the incidence of hysterectomy for bleeding disorders among sterilized women was compared with the incidence of hysterectomy for bleeding disorders among nonsterilized female population for the same age. The mean age of the study group was 44/4 +/- 5/7 and the mean age of the control group was 45/2 +/- 5/3, [p=0.424]. The mean parity of the study group was 3/8 +/- 1/8 and the mean parity of the control group was 3/5 +/- 1/4, [p=0.220]. So, in regard to age and parity, two groups were matched. Hysterectomies were performed for 160 cases and abnormal uterine bleeding was the cause of hysterectomy in 67 cases. Among 67 cases, 19 cases [37.3%] had previous tubal sterilization + hysterectomy [study group] and 48 cases [44%] were not undergoing tubal sterilization but had hysterectomy for abnormal bleeding causes [control group]. Statistical analyses showed that there were not significant differences between two groups, [RR=0.85; 95% CI: 0.56-1.28; p=0.418]. The result of this study showed that previous tubal sterilization is not a risk factor for undergoing hysterectomy because of abnormal uterine bleeding
