ABSTRACT
<p><b>OBJECTIVE</b>To observe whether bladder controller can restore bladder function in paraplegic dogs.</p><p><b>METHODS</b>Four 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.</p><p><b>RESULTS</b>Micturition 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.</p><p><b>CONCLUSION</b>Bladder controller together with a sacral deafferentation procedure can restore bladder function of paraplegic dogs.</p>
