Management of Uterus Bicornuate Non-Communicant Rudimentary Horn (UBNCRH), Renal Agenesis, and Severe Dysmenorrhoea with Adenomyosis: A Case Report on Improved Obstetrical Outcomes

A bicornuate uterus is a Müllerian duct anomaly that develops during embryogenesis. It is usually associated with poor pregnancy outcomes such as preterm birth, recurrent miscarriages and malpresentations. Most cases of uterus bicornuate non-communicant rudimentary horn (UBNCRH) present with endometriosis. The association of unilateral renal agenesis with adenomyosis in the non-communicating rudimentary horn is a rare occurrence and is associated with severe symptoms which was found in our case. Clinical suspicion and diagnosis, along with the removal of adenomyotic horn in a bicornuate uterus, significantly improved the symptoms and led to better obstetrical outcomes during the second pregnancy. This case highlights the diagnostic dilemma and management of such cases, leading to excellent symptomatic improvement and better pregnancy outcomes.
