BACKGROUND: Acute renal failure (ARF) occurs in up to 10% of critically ill patients, with significant associated morbidity and mortality. The optimal mode of renal replacement therapy (RRT) remains controversial. This retrospective study compared continuous renal replacement therapy (CRRT) and intermittent hemodialysis (IHD) for RRT in terms of intensive care unit (ICU) and hospital mortality, and renal recovery. METHODS: We reviewed the records of all patients undergoing RRT for the treatment of ARF over a 12-month period. Patients were compared according to mode of RRT, demographics, physiologic characteristics, and outcomes of ICU and hospital mortality and renal recovery using the Chi square, Student's t test, and multiple logistic regression as appropriate. RESULTS: 116 patients with renal insufficiency underwent RRT during the study period. Of these, 93 had ARF. The severity of illness of CRRT patients was similar to that of IHD patients using APACHE II (25.1 vs 23.5, P = 0.37), but they required significantly more intensive nursing (therapeutic intervention scale 47.8 vs 37.6, P = 0.0001). Mortality was associated with lower pH at presentation (P = 0.003) and increasing age (P = 0.03). Renal recovery was significantly more frequent among patients initially treated with CRRT (21/24 vs 5/14, P = 0.0003). Further investigation to define optimal timing, dose, and duration of RRT may be beneficial. CONCLUSIONS: Although further study is needed, this study suggests that renal recovery may be better after CRRT than IHD for ARF. Mortality was not affected significantly by RRT mode. 相似文献

From 1984 to 1990, 99mTc-DMSA renal scintigraphy was performed before and after nephrolithotomy (15 cases), pyelolithotomy (15 cases), percutaneous nephrolithotripsy (PNL: 15 cases) and extracorporeal shock wave lithotripsy (ESWL: 16 cases, 17 kidneys) in order to evaluate of influences of renal stone surgeries on split renal function. DMSA renal uptake change ratio of treated kidneys of nephrolithotomy (-24.94 +/- 5.60%) was significantly lower than that of PNL (-0.06 +/- 3.92%), pyelolithotomy (-4.08 +/- 4.79%) (p less than 0.01) and ESWL (-7.72 +/- 3.87%) (p less than 0.05). The average change ratios of contralateral kidneys were as follows: PNL 4.80 +/- 4.21% nephrolithotomy 4.67 +/- 4.73%, pyelolithotomy -1.46 +/- 5.39% and ESWL -2.02 +/- 4.44%. One to 3 weeks after PNL, the cold area on the renal image was found in 10 (66.7%) of 15 cases. In cases of ESWL, DMSA renal uptake decreased even 4-10 weeks (mean 7 weeks) after treatment. In conclusion, possivility of deterioration of renal function after ESWL was suggested. 相似文献

Angiograms following renal trauma in a ten-year-old girl were highly suggestive of renal neoplasm, especially Wilms' tumor. There are striking similarities between arteriograms after renal trauma and those showing neovascularity. 相似文献

An experience with 20 patients with renovascular hypertension and renal insufficiency secondary to renal artery stenosis is presented. The mean follow-up was 29 months. Eighteen patients had atherosclerotic renal artery stenosis and two patients had transplant renal artery stenosis. The mean preoperative blood pressure of 162 +/- 5 mmHg decreased significantly to 105 +/- 2 mm Hg (p less than 0.001). The serum creatinine also decreased from a mean preoperative level of 4.7 +/- 0.7 mg/dl to a mean postoperative level of 2.3 +/- 0.3 mg/dl (p less than 0.001). Similarly, the creatinine clearance improved from a mean preoperative level of 28 +/- 2 ml /min to a mean postoperative level of 45 +/- 8 ml/min (p less than 0.03). Four patients (20%) with improved renal function died from 4 days to 15 months postoperatively. Two patients (10%) have progressed to end stage renal disease. These findings demonstrate that renal revascularization is clearly beneficial in the short-term and long-term improvement of renal function. 相似文献

Dialysis and allotransplantation of human kidneys represent effective therapies to replace kidney function, but the former
replaces only a small component of renal function, and the latter is limited by lack of organ availability. Xenotransplantation
of whole kidneys from nonprimate donors is complicated by humoral and severe cellular rejection. The use of individual cells
or groups of cells to repair damaged tissue (cellular therapies) offers an alternative for renal tissue replacement. However,
recapitulation of complex functions such glomerular filtration and reabsorption and secretion of solutes that are dependent
on a three-dimensionally integrated kidney structure are beyond the scope of most cellular replacement therapies. The use
of nonvascularized embryonic renal primordia for transplantation circumvents humoral rejection of xenogeneic tissue and ameliorates
cellular rejection. Renal primordia are preprogrammed to attract a vasculature and differentiate into a kidney and in this
manner undergo organogenesis after transplantation into the mesentery of hosts. Here we review a decade’s progress in renal
organogenesis. 相似文献
