[Calculus-induced anuria. Apropos of 25 cases].

The objective of this study was to analyse the clinical and therapeutic aspects of stone-induced anuria based on the analysis of 25 cases. The mean age of the patients was 51 years. The stones were bilateral in 54% of cases, and consisted of uric acid stones in 52% of cases. The diagnosis was based on laboratory and radiological findings. Dialysis was indicated in eight patients because of major metabolic disorders. Urinary diversion was performed by insertion of a ureteric catheter or percutaneous nephrostomy. The medium- to long-term prognosis was favourable in two-thirds of cases, but 3 immediate deaths were observed due to delayed diagnosis.

[Anuria after delivery].

During the last decade certain peripartal complications decreased dramatically in industrialized countries. Here, a case of a 27 years old Caucasian primagravida will be presented. In the presence of symptoms of a severe preeclamptic condition with signs of an impending HELP syndrome the patient underwent Caesarean section. Within hours following surgery she developed complete anuria. Nuclear magnetic resonance imaging and histological evaluation of a renal biopsy led to the diagnosis of an acute, bilateral renal cortical necrosis. Besides the preeclamptic condition no further underlying disease was present, in particular no hemolytic-uremic syndrome. Following progress made in modern perinatal management renal cortical necrosis almost disappeared. Yet, in the presence of this disease a significant maternal morbidity and mortality still remains.

The benefits of daily hemofiltration in the management of anuria in patients with severe heart failure (NYHA IV).

The aim of the study was to evaluate the daily use of hemofiltration in patients with anuria and heart failure IV NYHA, and not reacting to pharmacological therapy. Patients were submitted to daily hemofiltration therapy considering: the dry weight, BP, pO2, creatininemia, natriemia, kaliemia, and magnesiemia. Every month an echocardiogram and an ECG were done. Two patients passed from IV to III class NYHA, with a reduction in the telediastolic diameter and improvement in the ejection fraction and in the cardiothoracic index. In NYHA IV patients, it was possible to obtain a very good improvement in the clinical situation, echocardiographic parameters and survival with daily hemofiltration.

Management of patients with hemolytic uremic syndrome demonstrating severe azotemia but not anuria.

There are no specific indications for dialysis in a patient with typical hemolytic uremic syndrome (D + HUS) who does not have anuria, hyperkalemia, volume overload, or severe acidemia. We managed five patients with D + HUS, aged 1.5-14 years, without dialysis despite marked azotemia, because they were not anuric and because they had none of the acid-base, fluid, or electrolyte perturbations that may have been indications for dialysis. Each had markedly elevated blood urea nitrogen (range 137-234 mg/dl) and serum creatinine concentrations (range 5.4-15.4 mg/dl). None was anuric and one was oliguric for 4 days. There were no complications and each recovered. We have reviewed the published literature on the use of dialysis in patients with D + HUS and have not found any guidelines that relate to the management of similar cases. It is our view that management of D + HUS patients without dialysis is appropriate when the patient is passing urine and the acid-base, serum electrolyte concentrations and fluid balances can be managed without dialysis.

Anuria due to bilateral ureteral obstruction by Aspergillus flavus in an adult male.

Mycelial clumps or bezoars (fungus balls) as a cause of upper urinary tract obstruction are rare, with fewer than 60 cases previously reported. Anuria due to bilateral ureteral obstruction with mycelial clumps is most rare. We report a man with bilateral ureteral obstruction by Aspergillus flavus and describe his diagnosis and treatment. It is remarkable that imaging modalities, including excretory urography, computed tomography, and retrograde ureteropyelography, did not identify filling defects to suggest a fungal causation of the ureteral obstruction, even in the presence of a rapidly progressing process. For this reason, one should consider a fungal infestation in high-risk patients with obstructive uropathy of unknown etiology.
