ABSTRACT
PURPOSE:
To evaluate the maximal intraluminal pressure (MIP) supported by canine cadaveric urinary bladders that underwent cystotomy followed by cystorraphy, with and without serosal patching-supplementation.METHODS:
Two groups (n=8 each) were formed, and in one (conventional) the cystotomy was closed with cushing pattern. In the other group (serosal), the same procedure was performed, and a piece of jejunum was used for the construction of the serosal patching over the cystorraphy. MIP was measured by means of an invasive blood pressure transducer with closed stopcock attached to a multiparameter monitor. At the end of each measurement, the bladder body circumference was assessed.RESULTS:
Mean±SD MIP sustained for the conventional and serosal groups were 28.88±5.08 and 65.38±10.99 mmHg, respectively (p<0.0001). Bladder circumference did not change significantly between groups (p=0.35) and did not correlate with MIP assessed in conventional (p=0.27; r=0.4379) and serosal groups (p=0.37; r=-0.3637).CONCLUSION:
Serosal patch-supplemented cystorraphies were able to sustain intraluminal pressures 55.8% higher, than nonsupplemented cystorraphies in specimens from canine cadavers.Key words
