In this article we have studied the pathophysiology of the lower urinary tract of patients with chronic Chagas' disease: Control Group (A) with 21 normal individuals; Group (B) 16 patients with positive serum for T. cruzi; Group (C) 16 patients with Chagas' cardiophaty and Group (D) 21 patients with Chagas' megacolon or megaesophagus. Urodynamics did not show difference (p > 0,05) among all groups as long as the following parameters are concerned: cystometric bladder capacity, voiding pressure, and urinary flow. On the contrary, a significant difference (p < 0,05) was observed between Groups A and D in the following parameters: abdominal pressure, detrussor pressure, urethral pressure and time of voiding. These findings suggest that Chagas' disease promotes changes of the lower urinary tract in patients that bears digestive dysfunction.
