Incidence of post-operative catheter related bladder discomfort in adult patients undergoing cardiac and thoracic surgeries: a prospective observational study

Presence of a catheter leads to catheter related bladder discomfort (CRBD) in 47-90% of patients. CRBD manifests as supra-pubic discomfort or a burning sensation, urinary urgency, frequency, and may be associated with the act of attempting to pull out the urinary catheter. Risk factors for CRBD include uro-gynecological surgeries, male gender, and Foley’s catheter greater than 18 Fr. Urinary catheterization is mandatory in patients undergoing cardiac surgery. No previous studies have documented the incidence of CRBD in patients undergoing cardiac surgery. This would be useful to know since patient discomfort due to CRBD may not only be distressing to the patient, but also may precipitate myocardial ischemia or increase the risk of bleeding due to increased sympathetic activity and/or patient agitation. Furthermore, knowing the baseline incidence would allow for institution of pharmacological options to treat the same. Thus, the aim of this study will be to evaluate the incidence and severity of CRBD in patients undergoing cardiothoracic surgery. Sub-group analyses will be carried out to assess the incidence and severity separately in cardiac and thoracic procedures.
