Exposing anterior prostatic urethra near the bladder neck and conjunct cystotomy modified the MPC procedure. This modified procedure preserved prostatic urethra intact and could also deal with intracystic lesions at the same time. The intact of prostatic urethra was kept completely or largely in 86 cases. The amount of blood loss during modified procedure was less. The mean operative time was 105 min. Seventy patients had been followed up for 3-24 months. The postoperative average Qmax was 19.2 ml/s. The cystourethrography revealed that the urethra and bladder neck were intact in 10 patients postoperatively. Furthermore, the prostatic urethra was obviously wider after modified MPC. The modified MPC can reduce the occurrence of urethra injury and enlarge the MPC indications. The modified technique is easy to perform with less complications and much satisfactory clinical result.展开更多

Successive APACHE Ⅱ scoring was adopted to evaluate the patients' physiological status, and then, internal fixa-tion of fractures and other definitive operations were performed.Results: All the patients were effectively treated with few complications, low deformity rate and no death.Conclusions: Appropriate evaluation of patients' physi-ological potential, right decision on surgical time and proper operative method can reduce the rates of complications, disability and death for patients with critical earthquake injuries.展开更多

However, there was a clear trend that the shorter the operative timing was, the lower the mortality and the higher functional survival rate were. In addition, the mean time from injury to operation of non-survivors was significantly longer than that of survivors.Conclusions: Operative timing has potential influences on the prognosis of patients with ASDH. Surgical evacuation of ASDH should be performed as soon as possible once the operation indication emerges.展开更多
