Clinical application of urodynamic study in patients with neurogenic bladder by pelvic fracture postoperative / 中国骨伤

<p><b>OBJECTIVE</b>To explore the clinical value of urodynamic study in patients with neurogenic bladder by pelvic fracture postoperative.</p><p><b>METHODS</b>Postoperative 12 cases with pelvic fracture resulted in uroschesis, there were 8 males and 4 females,and age from 26 to 70 years with an average of 46.5 years. Urodynamic study was done in patients at 1 d,1,3 weeks after operation and compared with 12 cases normal subjects.</p><p><b>RESULTS</b>There was a significant relationship between urodynamic parameter (including residual urine volume of bladder, max free flow, urethral closing pressure in filling end and so on) and course of disease. The residual urine volume of bladder and urethral closing pressure in filling end increased of urodynamic tests in all patients with uroschesis as compared with the normal subjects (P < 0.05); but max free flow decreased at 1 d, 1, 3 weeks after operation (P < 0.05). In the patients with uroschesis, residual urine volume of bladder markedly increased (P < 0.05) and urethral closing pressure in filling end markedly depressed (P < 0.05) at 1 week after operation than other time (at 1 d, 3 weeks after operation), but max free flow had not significant difference (P > 0.05).</p><p><b>CONCLUSION</b>Urodynamic study might evaluate regenerate the degree of neurogenic bladder by pelvic fracture postoperative and predict the prognosis of the neurogenic bladder.</p>

Clinical application value of laryngeal electromyography and laryngeal somatosensory evoked potential in patients with recurrent laryngeal nerve paralysis by anterior elective cervical surgery / 中国骨伤

<p><b>OBJECTIVE</b>To determine the clinical evaluation role of laryngeal electromyography (LEMG) and laryngeal somatosensory evoked potential (LSEP) in the recurrent laryngeal nerve paralysis by anterior elective cervical surgery.</p><p><b>METHODS</b>LEMG and LSEP were determined in 18 patients with recurrent laryngeal nerve paralysis by anterior elective cervical surgery at the 1st, 2nd and 4th week after operation. The comparison between the normal control (18 health adults) and the results of LEMG and LSEP were analyzed.</p><p><b>RESULTS</b>The latency prolonged and the amplitude decreased of LSEP in all patients as compared with the control group. Furthermore, reinneration potential increased gradually in all patients at the 1st, 2nd and 4th week after operation (P<0.05). The results of LEMG showed increase of denervation potential. The higher the amplitude of LSEP and LEMG, the better the prognosis of the recurrent laryngeal nerve paralysis.</p><p><b>CONCLUSION</b>LEMG and LSEP might evaluate regenerate the degree of recurrent laryngeal nerve injury caused by anterior elective cervical surgery and predict the prognosis of the recurrent laryngeal nerve paralysis.</p>
