Obstructive acute renal failure is both a medical and a surgical emergency. 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.

Cystitis glandularis or glandular metaplasia of the urinary bladder, is a benignreactive metaplasia of the urothelium, which occurs in the context of chronic irritation, in less than 2% of the general population. It is a condition in most casesasymptomatic, but also characterized by nonspecific symptoms and paraclinical findings, which is why this condition is underdiagnosed. Its evolution is mainly focused on the risk of malignant degeneration. This condition affects men much more commonly than women. Two forms of cystitis glandularis are recognized: typical and intestinal form. They differ in their histology, incidence, difficulty of diagnosis, and possible association with adenocarcinoma of the bladder. Diagnosis of certainty is histological by careful analysis of chips from bladder endoscopic resection. This rare pathology is managed by endoscopic bladder resection, with repeated cystoscopy as a monitoring tool. Extensive surgical is needed in severe or recurrent cases. We present here-in a case of a female patient having cystitis glandularis presenting with lower urinary tract symptoms. We review equally data reported in literature. To the best of our knowledge our case represents the fourth case of cystitis glandularis affecting a female patient reported in the English literature so far.
