Background: Certain procedures, particularly those used to treat
symptoms of bladder pain syndrome/interstitial cystitis (BPS/IC), involve filling
the bladder to or over its capacity for visualization and/or relief of symptoms.
Rarely, if excessive pressure or volume is used, bladders may rupture causing
significant harm to the patient. The purpose of this study was to identify
baseline data for pressure and volume when hydrodistention is attempted in
explanted cadaveric bladders, as well as determine bladder rupture pressure
changes in the acute post-cystorrhaphy state. Methods: Eight explanted
cadaveric bladders were filled using a systematic digital pump system.
Intravesical pressure and volume were monitored during the filling phase until
rupture. A two-layer cystorrhaphy was performed followed by bladder refilling to
point of rupture. The pressure-volume correlations were developed for the
explanted bladders, pre and post rupture. Results: The mean intact
bladder rupture volume was 1186.3 mL
