An evaluation of discrepancy in capacity and contour of the neurogenic bladder as shown on cystography and pyelography.
A significant difference in the filling of the bladder with contrast medium on intravenous pyelography as compared to cystography has been noted in patients with spinal cord injury. Bladder capacity and contour of the bladder wall have been assessed in 50 patients with impaired bladder innervation consequent upon spinal cord injury. In 32% of the patients the bladder capacity was significantly greater when measured on pyelography than that found in cystography. The causes for this discrepancy in bladder filling on the two examinations are discussed. The possibility of erroneous assessment of the capacity and contour of the neurogenic bladder on cystography is pointed out.
