RESUMO
In recent years, with the rapid development of rigid ureteroscopy and flexible ureteroscope lithotripsy in the field of urology, great changes have been made in the treatment of urinary calculi. Although flexible ureteroscope lithotripsy is easy to be damaged and expensive to maintain, it has high technical requirements for doctors, but it does not need to establish other traumatic channels, but uses the natural cavity of human urinary system, It has been paid more and more attention by urologists and has a good development prospect. Stone free rate is an objective index to judge the efficiency of flexible ureteroscope lithotripsy. The stone free rate and treatment after flexible ureteroscope lithotripsy have always been a difficult problem. Many scholars at home and abroad have studied the influencing factors of stone free rate after flexible ureteroscope lithotripsy, studies have shown that large stone load, hard stone composition, narrow angle of renal pelvis and calyceal and severe hydronephrosis are the main risk factors leading to the reduction of postoperative one-time stone free rate. In this paper, the research results in this field at home and abroad will be summarized.
RESUMO
Objective To investigate the differences of efficacy and economic efficiency between neuroendoscope and microscope for intracerebral hematomas cleaning operation. Methods From August 2014 to August 2015, clinical data of 68 cases with intracerebral hemorrhage were analyzed retrospectively. Hematoma evacuation was carried out by microscope in 37 cases (microscope group) received and 31 cases (endoscope group) underwent neuroendoscope. Following parameters were compared: the operation related index (hematoma clearance rate , intraoperative blood loss , the operation time , skin incision , bone window size ) , Glasgow Outcome Scale at 6 months after the operation, complications (intracranial infection, lung infections, gastrointestinal bleeding), medical economic parameters (the postoperative hospital stay, drug cost, cost other than drug, and total hospital cost). Results The hematoma clearance rate, Glasgow Outcome Scale at 6 months after the operation in the endoscope group were significantly better than those in the microscope group (P 0.05). The postoperative hospital stay, drug costs , no drug costs , and total hospital cost were significantly less in neuroendoscope group than that in microscope group (P< 0.01). Conclusion Neuroendoscopy has less trauma,there are some advantages of neuroendoscopy for intracerebral hematomas cleaning operation , such as minimal trauma , prominent effect , good prognosis and low cost. It should be widely applied in clinical practice.
