Continuous renal replacement therapy improves renal recovery from acute renal failure

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.     

Influences of renal stone surgeries on renal function--evaluation of renal function with 99mTc-DMSA renal scintigraphy]

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.     

Abnormal renal arteriography after renal trauma.

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.     

Extensive renal involvement by renal cell carcinoma

Experience with the management of 3 cases of bilateral renal adenocarcinoma and 1 case of unilateral carcinoma in the solitary kidney is presented. Two patients died of metastases six and thirteen months postoperatively, while one is alive with metastases at fourteen months and another is alive without metastases at four months. The literature is reviewed, and the various treatments are discussed.     

Reversible renal hypertension due to renal hygroma

A hygroma of the left kidney was found at surgery in a thirty-five-year-old woman, who presented with anemia, hypertension, and a left abdominal mass. There was a very high sedimentation rate and fine needle aspiration yielded bizarre cells which raised the possibility of malignancy. Compression of the kidney by the cystic structure probably interfered with renal blood flow and was responsible for the elevated blood pressure which receded to normal after removal of the cyst and the left kidney.
