RESUMO
Abstract According to the most recent guidelines, the use of intraoperative transesophageal echocardiography in valvular surgeries is well established, as well as its use in the diagnosis, management, and rescue of perioperative complications. The aim of this case report is to illustrate a condition in which its intraoperative use had a positive influence on the outcome.
Resumo O uso da ecocardiografia transesofágica no intraoperatório em cirurgias valvulares é bem estabelecido de acordo com os guidelines mais recentes, assim como o seu uso no diagnóstico, manuseio e resgate de complicações perioperatórias. O objetivo deste relato de caso é ilustrar uma situação em que o seu uso no intraoperatório influenciou de maneira positiva o seu desfecho.

INTRODUCTION AND HYPOTHESIS: The aim of this study was to evaluate the protective effect of intravesical oxybutynin on the bladder wall of rabbits with detrusor overactivity and partial bladder outlet obstruction (PBOO). METHODS: Forty-five North Folk male rabbits were randomly distributed into GI, used as control (n = 15), GII-PBOO (n = 14), and GIII-PBOO + intravesical oxybutynin (n = 15). Connective tissue and elastic fibers were quantified as volumetric density on picrosirius red and Weigert's Fuchsin-Resorcin-stained sections, respectively. RESULTS: In T2, bladder weight was significantly higher in animals in GII and GIII. Smooth muscle bundle diameter was increased by 42% in GII compared with GI (p < 0.02).Elastic fibers were significantly higher in GII and GIII as compared with control group. Collagen concentration in GIII and GII was significantly lower than G1 (p < 0.025). CONCLUSION: Intravesical oxybutynin protected against structural and functional detrusor modifications of the partially obstructed bladder.
