Histopathological studies on detrusor muscle in schistosomiasis haematobium patients with poor bladder contractility.
The electron microscopic structure of the detrusor muscle in schistosomiasis patients with poor bladder contractility as evaluated by urodynamic measures had been compared with normal detrusor muscle from non-schistosomiasis patients. In the patients with poor bladder contractility the detrusor was formed of muscle fibers which were smaller in size, widely separated by collagen and showed degenerative changes and hyalinosis. No evidence of smooth muscle hyperplasia, mitosis or fibroblastic proliferation was seen. This pathological changes in the bladder of schistosomiasis patients may explain the cause of poor contractility.
