Bladder pain syndrome and pregnancy

Bladder pain syndrome (BPS) is a poorly understood condition. In pregnancy, lower urinary tract symptoms and pain are common, but the possibility of BPS is rarely considered and almost never explored. The consequences of BPS on pregnancy and vice versa are poorly understood, and management options appear to be limited. This article reviews the current evidence to allow us to better counsel, investigate, diagnose and manage patients with suspected or known BPS who fall pregnant or who are considering pregnancy. MEDLINE, EMBASE and PubMed were searched for a combination of mesh terms of keywords: ‘cystitis’, ‘interstitial’, ‘bladder’, ‘pain’ and ‘pregnancy’. Relevant articles were identified, reviewed and further relevant articles identified from the references. BPS symptoms are very common in pregnancy, with limited data suggesting significant negative effects on the woman and pregnancy. There are safe options for investigation, diagnosis and management in pregnancy. There is a need to raise awareness of the impact of BPS symptoms in pregnancy and the available options for diagnoses and management, improving patient experience and outcomes. Patients with BPS or symptoms akin to BPS need not be abandoned in pregnancy. There is data to support them in making decisions around investigation and management in pregnancy.
