Abstract:
OBJECTIVETo observe whether bladder controller can restore bladder function in paraplegic dogs.
METHODSFour dogs were studied after their T(10) spinal cord was transected. Electrodes implanted around S(2) bilaterally were connected to subcutaneous recievers. Microsurgical techniques were employed in dorsal rhizotomy at S(1 - 3) intradural segment. After daily stimulation, the results of bladder controller were evaluated by micturition and vesicography.
RESULTSMicturition was given under electrical stimulation with a urine volume of 80 - 140 ml per time. The mode of micturition was post-stimulus voiding. Vesicography showed that the bladder was filled and bladder neck was open in the micturition course of electric stimulation. Residual urine volume was 15 - 20 ml.
CONCLUSIONBladder controller together with a sacral deafferentation procedure can restore bladder function of paraplegic dogs.
