The intention of this study is to educate and caution young surgeons about the possibility of stumbling into anatomical anomaly while operating for cancer cervix. Methods: This is an observational study, reflecting the numbers of congenital anomalies that were encountered while doing hysterectomy for cancer cervix in a tertiary care hospital within a 16 years span. Results: This study revealed the overall prevalence of congenital anomalies while performing hysterectomy for cancer cervix to be 2.9% and double ureter to be most common anomaly encounterd. Conclusion: Anatomical anomalies pose challenges when encountered while operating for cancer cervix. Surgical methods and dissections need to be planned accordingly to protect urinary pathways and vessels, that should be kept in mind particularly by low volume surgeons. Surgery can be disastrous if they is not recognized prior to procedure.
