Bladder outlet obstruction has been shown to cause detrusor contractile dysfunction. To determine if alterations in bladder metabolism may in part underlie these functional defects, we investigated the effects of mild outlet obstruction on the glucose metabolism of the rabbit urinary bladder. Mild outlet obstruction was created in mature male rabbits by the surgical placement of a silicon sleeve around the bladder neck. Two weeks after surgery, the in vitro ability of the obstructed bladder tissues to metabolize glucose was compared to that of the controls. The results can be summarized as follows: 1) The bladder wet weight increased 2.3-fold following two weeks of obstruction. 2) Obstructed bladder tissues had a reduced glucose consumption as compared to the controls. 3) CO2 generation was significantly reduced by 31% in obstructed bladder tissues whereas lactate formation increased significantly by 22%. 4) Tissue concentrations of ATP, creatine phosphate, and glycogen before incubation showed no significant differences between control and obstructed bladder tissues. In summary, bladder tissues following two weeks obstruction showed a decrease in aerobic metabolism and an increase in anaerobic metabolism. Previous studies have indicated that the ability of the bladder to maintain a contraction and empty may be directly related to aerobic metabolism. Therefore, the decrease in aerobic metabolism (even in the presence of increased anaerobic metabolism) may in part explain the decreased ability of the obstructed bladder to empty.
