“…Obstructive anuria of the excretory pathway is defined as the cessation of diuresis (200 or 400ml), along with an empty balder on urinary system, with the cause being located at a supra-vesical level including the urethral vessels. Anuria is secondary to complete obstruction bilaterally in the presence of two kidneys or unilateral in cases with a single kidney [1]. Anuria causes post-renal kidney failure because the obstacle is located downstream of the kidneys (2).…”

“…Bilateral or unilateral pyelocalicial cavities dilation on a unique kidney is almost pathognomonic of obstruction of the excretory pathway. However, there are between 5 and 20% of false positives related to an intra sinus fluid image due to a parapyelic cyst, and around 10% of false negatives when the excretory tract is not dilated [1].Kidney ultrasound should also analyze kidney size and cortical index, the presence of stones, retroperitoneal organs and the search for a pelvic tumor. The non-contrast CT scan is not a systematic examination during the emergency management of malignant obstructive anuria.…”

“…It can be performed without injection or be performed with gadolinium injection: injected MRI (sequence T1), reproducing an intravenous urography. [1] Kidney scintigraphy is used outside the emergency situation to assess residual kidney function. Young people with an early diagnosis will have a better renal prognosis [7].In our center, access to ultrasound and CT scan in emergency is easy, however the MRI is not available in an emergency situation.…”

“…Calorie and nitrogen intake should be increased as acute renal failure generates hypercatabolism. Finally, prevention of stress ulcer must be ensured by prescribing a proton pump inhibitor [1]. After the diversion, the early detection of post-obstructive diuresis is important.…”

Introduction : Obstructive anuria due to pelvic cancers is the most common obstructive anuria in our context, its diagnosis is easy, but it causes a lot of morbidity with often heavy and long management. Materials and methods : This is a retrospective study containing 40 cases of confirmed neoplastic anuria treated in the urology department at the Ibn Rochd University Hospital in Casablanca Morocco between January 2016 and October 2018. Purpose : The aim of our study was to establish the epidemiological, clinical, therapeutic and natural historyin patients with neoplastic obstructive anuria. Results : The mean age was 56 years old with a notable female predominance. The male to female ratio was 0.6. Sixty percent (60%) of our patients were consulted within24 hours after the onset of anuria, the main symptoms preceding or accompanying anuria were lower back pain (75%) and hematuria (37.5%). Criteria for a positive diagnosis included urinary retention with complete absence of diuresis, the anuria was confirmed by probing or ultrasound, dilation of the urinary excretory system on ultrasound and acute impairment of renal function. To prevent patient from going into metabolic disorders, hemodialysis was performed in 27 patients (67.5%). Internal diversion of urine by mounting a JJ catheter was initially attempted in 40% of the cases. In case of attempt failure, or in case of locally advanced pelvic tumors, percutaneous nephrostomy was performed with a success rate of 100%. Upon follow up for 30 months, mortality rate was 5% (n=2), 95% of the patients benefited from a specialized follow-up for their etiological neoplasm. Conclusion : The management of neoplastic obstructive anuria must be rapid, the type of urinary diversion is chosen according to the clinical presentation and the technical platform available.
