The standard radiological investigations in the emergency setting include X-ray, ultrasonography and computed tomography. But occasionally the cause of obstruction may be elusive.METHODS: We present a case of obstructive uropathy due to bilateral stones presenting as acute renal failure. The patient underwent successful shock wave lithotripsy(SWL) for dissolution of calculi.RESULTS: The patient was successfully treated, and reported asymptomatic in a follow-up.CONCLUSION: Close collaboration between nephrological, urological, and radiological services is required.展开更多

Whatever the cause, urinary tract obstruction suddenly opposes glomerular filtration and is responsible for tubulointerstitial lesions. It accounts for 10% of acute renal failure (ARF). The aim of this study was to identify the causes and prognosis of cases of acute obstructive renal failure managed at the Centre National d’hémodialyse Donka. Material and Methods: This was a prospective descriptive study lasting 6 months, from September 1, 2022 to February 29, 2023. All patients undergoing haemodialysis for acute obstructive renal failure who agreed to participate in the study and whose medical records were complete were included. Results: During the course of the study, we registered 97 haemodialysis patients, including 20 cases (20.62%) of acute obstructive renal failure. The mean age of the patients was 57.8 ± 10.54 years, with a male predominance of 11 cases (55%) and a sex ratio of 1.22. The reasons for consultation were dominated by physical asthenia 11 cases (55%), lumbar pain 9 cases (50%), vomiting 6 cases (30%) and acute urine retention 6 cases (30%). Arterial hypertension 16 cases (80%) and urinary tract infection 10 cases (50%) were the most common antecedents. The etiologies of RAOI were dominated by lithiasis 10 cases (50%), neoplasia 6 cases (30%) and benign prostatic hypertrophy 3 cases (15%). mean creatinine was 1267.60 ± 710.76 μmol/l with extremes of 243 μmol/l and 2822 μmol/l, mean urea was 39.56 ± 18.36, hyperkalemia in 14 cases (70%) and hyponatremia in 8 cases (40%). After hemodialysis, 9 cases (45%) recovered renal function, 4 cases (20%) became chronic and 7 cases (35%) died. Conclusion: The frequency of AKI remains non-negligible in our department, and early detection and prompt management would considerably reduce the morbidity and mortality associated with this pathology.展开更多

The first treatment modality is urological by relief of obstruction. Post-obstructive diuresis is an abnormal condition of prolonged polyuria, involving both excessive solute and water loss, after acute drainage of obstructed urinary tract system. Physiopathology mechanisms are multiples. In most patients, diuresis will resolve once the kidneys normalize the volume and solute status and homeostasis is achieved. Post-obstructive diuresis can occur in up to 50% of patients with substantial urinary tract obstruction and can be life-threatening if it becomes pathologic. It can be detected by hourly monitoring of diuresis. Medical treatment of post-obstructive diuresis consists of oral or intravenous fluids adjusted to the findings of clinical examination, diuresis (volume and electrolytes) and close monitoring of patient. Fluid compensation should be tapered off over several days. Patients at high risk of post-obstructive diuresis should be identified and appropriately monitored.展开更多
