OBJECTIVE: To evaluate the incidence of urinary tract injury due to hysterectomy for benign disease. STUDY DESIGN: Patients were enrolled prospectively from 3 sites. All patients undergoing abdominal, vaginal, or laparoscopic hysterectomy for benign disease underwent diagnostic cystourethroscopy. RESULTS: Four hundred seventy-one patients participated. Ninety-six percent (24/25) of urinary tract injuries were detected intraoperatively. There were 8 cases of ureteral injury (1.7%) and 17 cases of bladder injury (3.6%). Ureteral injury was associated with concurrent prolapse surgery (7.3% vs 1.2%; P = .025). Bladder injury was associated with concurrent anti-incontinence procedures (12.5% vs 3.1%; P = .049). Abdominal hysterectomy was associated with a higher incidence of ureteral injury (2.2% vs 1.2%) but this was not significant. Only 12.5% of ureteral injuries and 35.3% of bladder injuries were detected before cystoscopy. CONCLUSION: The incidence of urinary tract injury during hysterectomy is 4.8%. Surgery for prolapse or incontinence increases the risk. Routine use of cystoscopy during hysterectomy should be considered. 相似文献

The need to evaluate the effectiveness of clinical practice to justify expensive therapy in the face of financial constraints in all areas of health care delivery makes it necessary to identify groups of patients who are likely to benefit most from treatment. Various risk stratification methods have been used for analyzing survival probabilities for patients receiving renal replacement therapy. Complicated risk stratification methods produce large numbers of risk groups of small sizes, which makes comparison between individual centers difficult. We compared three simple methods of risk stratification, that divided patients into low-, medium-, and high-risk groups, in a cohort of 1,407 patients who commenced renal replacement therapy in five European countries during a 7-year period. Method 1 considered age (>55 years) and diabetes alone; method 2 used a higher age limit (>70 years) and comorbid illnesses, including those other than diabetes; and method 3 used only the number of comorbidities (none, 1, or > or =2) for stratification. Kaplan-Meier survival curves were constructed for comparison between risk groups and Cox's regression model used to assess strength of relationship with mortality. Although patient survival was significantly different between the low-, medium-, and high-risk groups using all three methods, Cox's regression analysis showed that method 2 provided the greatest discrimination between risk groups. In predicting mortality, method 2 (based on comorbidities and age) showed the highest sensitivity and specificity (84% and 80%, respectively) compared with method 1 (80% and 74%) and method 3 (64% and 82%). Validation of this approach in other populations in a prospective study is required before this method, which takes into account the influences of both age and comorbidity for risk stratification, can be used for comparing survival data and for presenting results of renal replacement therapy. 相似文献

Background
The management of diabetic patients with refractory macular oedema or patients with no adequate pre-operative view to administer laser treatment provide a challenge to the ophthalmologist. We wished to assess the use, safety and effect of intravitreal triamcinolone injection at the time of cataract surgery in patients with diabetic foveal oedema and sight limiting lens opacities. 相似文献59.
The methods used to evaluate event-related potentials (ERPs) are generally insensitive to nonlinear responses. Our goal was to show that nonlinear ERPs could be detected using recurrence analysis (RA). When fixed-phase sine signals were added to baseline electroencephalograms (EEGs), the added linear determinism was detected by signal averaging, as expected, and by RA. However, when nonlinear determinism was simulated by adding either random-phase sine or Lorenz signals, the added signals were detected only by RA. Auditory evoked potentials (AEPs) were studied in five subjects using RA. We detected not only the characteristic linear effects caused by onset and offset of the sound, but also nonlinear AEPs not previously reported; they occurred at 473-661 ms after onset, and 282-602 ms after offset, depending on the subject. In five other subjects we found nonlinear magnetosensory evoked potentials; they occurred at 209-354 ms after field onset, depending on the subject. RA was less sensitive than time averaging for detecting linear ERPs, but had the advantage of being able to detect nonlinear ERPs. 相似文献
