Allopurinol is a xanthine oxidase inhibitor used in management of chronic gout. It acts by reducing the amount of uric acid by inhibiting purine metabolism. A middle-aged hypertensive female who was on allopurinol for 7 months presented with generalized weakness and exertional dyspnea. Investigations revealed pancytopenia: normocytic normochromic anemia (Hb-3.2g/dL, TLC-3400/mm3) and severe thrombocytopenia (Platelets-1000/mm3) with mild hepatosplenomegaly and grade 2 medico renal disease with normal cardiac status. Nutritional, hemolytic and infective causes were ruled out. She was transfused with fresh whole blood, platelets, administered empirical antibiotics and started on steroids. Initially, she responded to treatment but later developed an episode of convulsions with anuria and succumbed to leukopenic sepsis secondary to hypo/aplastic anemia probably due to allopurinol. Allopurinol is used extensively in the management of chronic gout and is well tolerated due to its safety profile. But we here report a case of allopurinol induced aplastic anemia leading to the demise of a patient. Allopurinol though safe needs careful monitoring.

Acute kidney injury (AKI) can be a significant clue to solving a puzzling patient presentation. Postrenal AKI should be suspected if imaging shows any degree of hydronephrosis and can be caused by a variety of conditions. Diagnosis of urinary obstruction without significant dilatation of the pelvic-ureteral system requires a higher degree of suspicion, and hence, its identification can become late. In patients without prior cancer screening, the etiology of obstructive uropathy must be broadened to include primary or metastatic malignancy. Clinicians should look beyond the AKI to properly evaluate the etiology of the patient's presentation and symptoms. In this report, we present the case of a middle-aged female with no known past medical history who presented with AKI secondary to malignant retroperitoneal fibrosis as the first manifestation of metastatic breast cancer. Her AKI was associated with acute onset anuria and was found to have nondilated postrenal AKI with no significant abnormalities on renal imaging. Early onset anuria in the setting of AKI, which persists despite fluid resuscitation, can suggest complete urinary tract obstruction even with reassuring results of initial renal images, and in the patient with no history of cancer screening, malignancy should be suspected as a primary cause of obstructive uropathy.

Denys-Drash syndrome is characterized by progressive nephropathy, gonadal dysgenesis, and Wilms tumor caused by a WT1 gene mutation. Infants with Denys-Drash syndrome frequently experience severe hypertension, but detailed clinical manifestations have yet to be clarified. Cases of infantile-onset Denys-Drash syndrome with severe hypertension at our hospital were retrospectively analyzed and the pathogenesis of hypertension was investigated. Six infants who received the diagnosis of Denys-Drash syndrome at the median age of 10 days (range: 2-182 days) were enrolled. Five infants had the complication of severe hypertension within a few days of diagnosis. All the patients showed rapid progression to end-stage renal disease and urgently required dialysis due to anuria/oliguria and hypervolemia with a median duration of 7.5 days (range: 0-17 days) on the day after diagnosis. Even under dialysis, all the patients continued to need antihypertensive treatment. Five patients underwent a preventive nephrectomy for Wilms tumor, and one patient underwent a nephrectomy due to progression to Wilms tumor. Two patients developed hypotension after a nephrectomy. The main causes of hypertension were hypervolemia in the predialysis stage, renin-associated hypertension in the dialysis stage, and multiple factors, including increased plasma catecholamine-associated hypertension in the postnephrectomy dialysis stage. At last the follow-up after bilateral nephrectomy, four of the five patients required antihypertensive treatment. Not all the patients showed target organ complications caused by hypertension. Severe hypertension is a common complication of infantile-onset Denys-Drash syndrome. The possibility of hypotension after nephrectomy should be considered in patients with Denys-Drash syndrome.

INTRODUCTION
Obstructive Anuria (OA) constitutes a diagnostic and therapeutic emergency involving the vital prognosis of the patient requiring an emergency and multidisciplinary care. The etiologies are multiple and the pelvic gynecological cancers represent one of the main causes of OA.
OBJECTIVES
Describing the epidemiological, clinical, paraclinical, etiological, therapeutic and progressive aspects of obstructive anuria of the gynecological origin, in the urology department in the University Hospital Center.
MATERIALS AND METHODS
This is a descriptive and retrospective study spread over a period of 4 years (2016-2019) including all the patients admitted for management of OA secondary to the pelvic gynecological cancers.
RESULTS
102 patients were included in the study whose the mean age was 60 years old (36-84). The main etiologies were cervical cancer (93%), followed by endometrial cancer (5%) and ovarian cancer (2%). The mean time to consultation was 4.5 days (1-8). The main circumstances of discovery were anuria (67%), oligoanuria (21.5%), low back pain (17%) and hematuria (9%). Clinical examination found an altered general condition (Performans Status> 2) in 37.5% of the patients and an advanced local state in 96% of the patients. The means of serum creatinine and blood urea were 122 mg/l and 2.4 g/l respectively. The hemodialysis (HD) was indicated in 29.5% of patients with life-threatening hyperkalemia (Kalemia> 6.4meq/l) with cardiac distress (20.5%), hydro-sodium overload (6%) and metabolic acidosis (3%). The ultrasound-guided percutaneous nephrostomy was the main method of diversion (92%) followed by the placement of the double J stent (8%). The outcome was favorable in the majority of patients with normalization of the kidney function (88%) while 7% of cases kept chronic kidney disease. The main complication was an obstruction syndrome (41%), followed by infections of the percutaneous nephrostomy tubes (13%) and venous thrombosis of the lower limbs (3%). In addition, the mortality was estimated at 5%.
CONCLUSION
The obstructive anuria constitutes a medico-surgical emergency involving the patient's vital prognosis. Our study notes the frequent association between the pelvic gynecological tumors and the obstructive anuria, which can be explained by the advanced stage of these tumors. This work underlines the fundamental interest of early diagnosis of these tumors to enable the prevention of the OA.

A 40-year-old Syrian man presented to the emergency department with a 5-day history of anuria. He had previously excreted dark urine. Major rhabdomyolysis and crush kidney were found, meaning that hemodialysis was immediately initiated. A detailed patient history in the patient's mother tongue revealed indications of metabolic myopathy. The PYGM-associated glycogen storage disease type V (McArdle disease) was confirmed by next generation sequencing panel diagnostics. The most important treatment approach is to avoid rhabdomyolysis through only moderate physical exertion.

Review
The kidney is frequently involved by autoimmune rheumatic diseases. The renal manifestations may be variable, ranging from asymptomatic proteinuria and microscopic haematuria to nephrotic syndrome and rapidly progressive glomerulonephritis or vasculitis. In a number of cases the kidney involvement is related to the treatment of the original disease and may represent a major cause of morbidity and mortality. Thus, it is important for nephrologists and rheumatologists to remember that dysfunction of the kidney may be part of the primary systemic disorder or consequence of its pharmacotherapy. In the first part of this review we will analyse the kidney involvement in four autoimmune connective tissue diseases: systemic lupus erythematosus, Sjögren syndrome, polymyositis/dermatomyositis, and systemic sclerosis. Renal disease is common in lupus and is a main cause of morbidity and mortality. About 10% of patients with Sjögren syndrome may present interstitial nephritis or, more rarely, glomerulonephritis. Myoglobinuria and acute kidney injury is a frequent complication of polymyositis. Renal disease is one of the most serious complications of systemic sclerosis and may present with a dramatic renal crisis, characterized by malignant hypertension, oligo-anuria, and microangiopathic thrombocytopenic anaemia.

Review
A novel coronavirus disease (COVID-19), caused by a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), was discovered in Wuhan, China, in December 2019, and the world has suffered from a pandemic. As of 22nd March 2020, at least 185 countries worldwide had been affected by COVID-19. SARS-CoV-2, leading to COVID-19 pneumonia, infects cells through ACE-2 receptors. The disease has different clinical signs and symptoms, including chills, high fever, dyspnea, and cough. Other symptoms including haemoptysis, myalgia, diarrhoea, expectoration, and fatigue may also occur. The rapid rise in confirmation cases is severe in preventing and controlling COVID-19. In this review, the article will explore and evaluate the insights into how COVID influences patients with other comorbid conditions such as cardiovascular disease, diabetes, Parkinson's, and how conditions Urolithiasis, anosmia, and anuria may develop after infection. The virus mutates and the variants are now prevalent in the present scenario where the world stands in eradicating the pandemic by looking into the development of vaccines by several countries and how the vaccination can temporarily help prevent COVID spread.

BACKGROUND
Fluid overload is common in patients in the intensive care unit (ICU) and ultrafiltration (UF) is frequently required. There is lack of guidance on optimal UF practice. We aimed to explore patterns of UF practice, barriers to achieving UF targets, and concerns related to UF practice among practitioners working in Europe.
METHODS
This was a sub-study of an international open survey with focus on adult intensivists and nephrologists, advanced practice providers, and ICU and dialysis nurses working in Europe.
RESULTS
Four hundred eighty-five practitioners (75% intensivists) from 31 countries completed the survey. The most common criteria for UF initiation was persistent oliguria/anuria (45.6%), followed by pulmonary edema (16.7%). Continuous renal replacement therapy was the preferred initial modality (90.0%). The median initial and maximal rate of net ultrafiltration (UF) prescription in hemodynamically stable patients were 149 mL/hr. (IQR 100-200) and 300 mL/hr. (IQR 201-352), respectively, compared to a median UF rate of 98 mL/hr. (IQR 51-108) in hemodynamically unstable patients and varied significantly between countries. Two-thirds of nurses and 15.5% of physicians reported assessing fluid balance hourly. When hemodynamic instability occurred, 70.1% of practitioners reported decreasing the rate of fluid removal, followed by starting or increasing the dose of a vasopressor (51.3%). Most respondents (90.7%) believed in early fluid removal and expressed willingness to participate in a study comparing protocol-based fluid removal versus usual care.
CONCLUSIONS
There was a significant variation in UF practice and perception among practitioners in Europe. Future research should focus on identifying the best strategies of prescribing and managing ultrafiltration in critically ill patients.

Refeeding syndrome (RFS) is a rare, potentially life-threatening, condition seen in malnourished patients starting refeeding. RFS may provoke seizures and acute encephalopathy and can be considered an internal severe neurotrauma in need of specific treatment. The objective was to describe course of disease, treatment and, for the first time, multimodal monitoring output in a comatose patient suffering RFS. After gastric-banding and severe weight loss, the patient initiated self-starving and was transferred to our intensive care unit (ICU) following rapid refeeding. At arrival, seizures, decrease in consciousness (GCS 7) and suspected acute encephalitis was presented. Serum albumin was 8 g/l. Intracranial pressure (ICP), invasive blood pressure and electrocardiography (ECG) were monitored. Pressure reactivity (PR) and compliance (RAP) were calculated. The patient developed congestive heart failure, anuria and general oedema despite maximal neuro- and general ICU treatment. Global cerebral oedema and hypoperfusion areas with established ischemia were seen. ECG revealed massive cardiac arrhythmia and disturbed autonomic regulation. PR indicated intact autoregulation (-0.06 ± 0.18, mean ± SD) and relatively normal compliance (RAP = 0.23 ± 0.13). After 15 days the clinical state was improved, and the patient returned to the primary hospital. RFS was associated with serious deviations in homeostasis, high ICP levels, ECG abnormalities, kidney and lung affections. It is of utmost importance to recognize this rare syndrome and to treat appropriately. Despite the severe clinical state, cerebral autoregulation and compensatory reserve were generally normal, questioning the applicability of indirect measurements such as PR and RAP during neuro-intensive care treatment of RFS patients with cerebral engagement.

Calculus anuria is a catastrophic condition with dire consequences if not treated promptly. The purpose of this study was to identify factors which influence the short-term outcome of patients with calculus anuria. A retrospective analysis was conducted from January 2016 to December 2021, in children up to the age of 18 years, who presented with calculus anuria and required emergency decompression at Sindh Institute of Urology and Transplantation, Pakistan. One hundred and twenty-five children were included. Majority were born to consanguineous parents and a few of them had positive family history of stone disease. Severe illness was found in 25 (20%) patients and among them 8 (32%) required hemodialysis. Decompression by double J stenting is the preferred intervention in our institute and was done in 106 (85%) children, followed by percutaneous nephrostomy tube in 10 (8%) successfully. A small number of patients, 9 (7%) required both procedures to relieve their obstruction. A significant number of patients, about 115 (92%), attained normal renal functions after intervention. No pertinent factors were identified, relating to incomplete renal recovery in nine (7%) of the patients who unfortunately progressed to chronic kidney disease.
