[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.
