The light and electron microscopic structure of detrusor muscle of trabeculated urinary bladder from patients with urodynamically proved bilharzial outflow obstruction had been compared with normal detrusor muscle. In bilharzial outflow obstruction, the detrusor muscle bundles were formed of relatively smaller smooth muscle cells widely separated by dense connective tissue, fatty infiltration, bilharzial ova, inflammatory cells and hyalinosis. No evidence of smooth muscle hyperplasia, mitosis, or fibroblastic proliferation. At the level of electron microscopy. The connective tissue infiltration was proved to be microfibriles apparently in continuity of the basal lamina of the smooth muscle. These pathological changes can explain both the morphological and urodynamic changes in bilharzial urinary bladder outflow obstruction.
