INTRODUCTION
Ureteral stones may have an influence on kidney functions due to postrenal obstruction or urinary infections. Urgent decompression or stone removal is necessary and recommended to prevent further complications in case of severe conditions such as anuria and urosepsis. Although it is believed that ureteral stone removal would result in renal function improvement, there are still unclear points on whether ureteroscopy (URS) can provide benefit as expected and has some adverse effects. In this study, we aimed to evaluate the alteration of kidney functions of patients who undergo rigid or flexible URS for ureteral stones and find if there are any influencing factors on kidney function alteration.
MATERIALS AND METHOD
We analyzed 126 patients who underwent retrograde intrarenal surgery (RIRS) for renal stones between May 2018 and February 2020 prospectively. The estimated glomerular filtration rate (eGFR) was calculated on the day before the surgery, by modification of diet in renal disease (MDRD) formula. The calculation was repeated and saved three times during follow-up for the same patient; on the day after the operation, on the postoperative 30th day, and the postoperative 90th day. Then, we evaluated the renal function by comparing eGFR and assessed the predicting factors affecting the kidney function.
RESULTS
Preoperative mean eGFR was 82.28 ± 25.20 mL/min/1.73 m for the study group. Mean eGFR was calculated 90.92 ± 22.97 mL/min/1.73 m on the first postoperative day, and 94.54 ± 21.95 mL/min/1.73 m on the third-month follow-up. The mean change in eGFR was 8.63 ± 16.68 mL/min/1.73 m in the early period and 12.26 ± 21.09 mL/min/1.73 m in the long-term follow-up period. Fifty-one patients improved on chronic kidney disease (CKD) stage, and 13 deteriorated in three months follow-up.
CONCLUSION
Removing the stone and relieving the obstruction by ureteroscopic treatment have an alteration on eGFR. Although eGFR improves in the short-term follow-up, amelioration is evident in long-term follow-up, especially in female patients. The other predictive factors for eGFR improvement after URS are the presence of ureteral obstruction and high preoperative serum creatinine levels.

Review
Unlike other adverse drug reactions, visceral organ involvement is a prominent feature of drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and correlates with mortality. The aim of this study was to systematically review cases published in PubMed-indexed, peer-reviewed journals in which patients had renal injury during the episode of DRESS syndrome (DS). We found 71 cases, of which 67 were adults and 56% were males. Female sex was associated with higher mortality. Chronic kidney disease (CKD) was present in 14% of patients who developed acute kidney injury (AKI) during DS. In 21% of cases, the kidneys were the only visceral organ involved, while 54% of patients had both liver and kidney involvement. Eosinophilia was absent in 24% of patients. The most common classes of medication associated with renal injury in DS were antibiotics in 34%, xanthine oxidase inhibitors in 15%, and anticonvulsants in 11%. Among antibiotics, vancomycin was the most common culprit in 68% of patients. AKI was the most common renal manifestation reported in 96% of cases, while isolated proteinuria or hematuria was present in only 4% of cases. In cases with AKI, 88% had isolated increase in creatinine and decrease in glomerular filtration (GFR), 27% had AKI concomitantly with proteinuria, 18% had oliguria, and 13% had concomitant AKI with hematuria. Anuria was the rarest manifestation, occurring in only 4% of patients with DS. Temporary renal replacement therapy was needed in 30% of cases, and all but one patient fully recovered renal function. Mortality of DS in this cohort was 13%, which is higher than previously reported. Medication class, latency period, or pre-existing CKD were not found to be associated with higher mortality. More research, particularly prospective studies, is needed to better recognize the risks associated with renal injury in patients with DS. The development of disease-specific biomarkers would also be useful so DS with renal involvement can be easier distinguished from other eosinophilic diseases that might affect the kidney.

OBJECTIVES
to verify the relationship of cardiovascular diseases with acute kidney injury and assess the prognosis of patients in renal replacement therapy.
METHODS
a cohort study, carried out in a public hospital specialized in cardiology. Treatment, comorbidities, duration of treatment, laboratory tests, discharge and deaths were analyzed.
RESULTS
of the 101 patients, 75 (74.3%) received non-dialysis treatment. The most frequent cardiological diagnoses were hypertension, cardiomyopathies and coronary syndrome. Hospitalization in patients undergoing dialysis was 18 days, hemoglobin <10.5g/dl and anuria in the first days of hospitalization contributed to the type of treatment. Each increase in hemoglobin units from the first day of hospitalization decreases the chance of dialysis by 19.2%. There was no difference in mortality.
CONCLUSIONS
the main cardiological diseases were not predictive of dialysis indication, and clinical treatment was the most frequent. Anuria and anemia were predictors for dialysis treatment.

Observational Study
As Odisha is an endemic region for malaria with many acute kidney injury (AKI) cases, this study evaluated the clinical profile and treatment outcomes of patients with malaria complicated by AKI. This prospective observational study was conducted between December 2015 and September 2017. Detailed histories and clinical examinations were recorded. On admission, tests for routine hematology, plasma glucose, liver function, renal function, serum electrolytes, thick smears, thin smears, and malarial parasites were performed. Of the 958 AKI malarial patients admitted, 202 (82.6 % males) were included in the study, with a mean age of 38.37 years. In total, 86.14%, 3.46%, and 10.39% of patients had Plasmodium falciparum, Plasmodium vivax, and mixed malaria, respectively. Headache and decreased urination (83.66% each) were the most common symptoms after fever (100%). Anuria and oliguria were reported in 5.95% and 67.82% of patients, respectively, whereas 26.23% reported a urine output of >400 mL/24 h. All patients had raised serum creatinine and urea levels, and >60% had anemia, proteinuria, and/or hyponatremia. Multiple organ dysfunction syndrome was observed in 62.87% of patients. Acute tubular necrosis was seen in 60% of renal biopsy specimens (n = 15). Of the 75.75% of patients requiring dialysis, 82.12% and 17.88% of patients required hemodialysis and peritoneal dialysis, respectively, during which 11 patients died. AKI, a serious complication of P. falciparum or P. vivax malaria, is a life-threatening condition. Fever, anemia, oligo/anuria, hepatic involvement, cerebral malaria, high serum creatinine and urea, and disseminated intravascular coagulation were the main predictors of mortality in our study.

Review
Intravenous fluid therapy has long been the mainstay of treatment of kidney disease, including acute kidney injury and uremic crisis associated with chronic kidney disease. Careful management of fluid dose is critical, as animals with kidney disease may have marked derangements in their ability to regulate fluid homeostasis and acid-base status. Understanding of the physiology of renal fluid handling is necessary, along with repeated attention to parameters of fluid status, electrolytes, and acid-base balance, to achieve optimal hydration status and avoid further damage or decrease in function from dehydration or overhydration.

INTRODUCTION
The obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is characterized by the triad uterus didelphys, obstructed hemivagina, and ipsilateral renal dysplasia. To make a radiological diagnosis, knowledge of this syndrome is of paramount importance. Early recognition may prevent complications such as unnecessary surgical procedures, endometriosis, and infections, which could adversely affect fertility.
CASE REPORT
A 1-day-old female newborn in whom a right-sided cystic kidney abnormality was seen on antenatal ultrasound was admitted with anuria and intralabial mass. Besides the multicystic dysplastic right kidney, ultrasound revealed a uterus didelphys with right-sided uterus dysplasia, an obstructed right hemivagina, and an ectopic ureteric insertion. The diagnosis of obstructed hemivagina and ipsilateral renal anomaly syndrome with hydrocolpos was made and the hymen was incised. Later, ultrasound helped in diagnosing a pyelonephritis in the afunctional right kidney that was not draining into the bladder (hence no culture could be obtained), requiring intravenous antibiotics and a nephrectomy.
DISCUSSION
Obstructed hemivagina and ipsilateral renal anomaly syndrome is an anomaly of the Müllerian and Wolffian ducts of unknown cause. Patients typically present after menarche with (progressive) abdominal pain, dysmenorrhea, or urogenital malformations. In contrast, prepubertal patients can present with urinary incontinence or an (external) vaginal mass. The diagnosis is confirmed by an ultrasound or magnetic resonance imaging. Follow-up includes repeated ultrasounds and monitoring of kidney function. Treatment consists of drainage of the hydrocolpos/hematocolpos; in some cases, further surgery is indicated.
CONCLUSION
Consider obstructed hemivagina and ipsilateral renal anomaly syndrome in girls with genitourinary abnormalities: early recognition prevents complications later in life.

The bladder is both an intraperitoneal and extraperitoneal structure. Its anatomical position increases its risk of rupture. The resultant urine leak or extravasation can be intraperitoneal, extraperitoneal, or even both-with the former leading to more sinister outcomes. Intraperitoneal bladder rupture can lead to urinary ascites which along with anuria and abdominal pain, can present with an apparent abrupt decline in renal function as the creatinine-rich products diffuse across the peritoneal membrane. Glomerular filtration rate, a measure of kidney function is related to the levels of serum creatinine. Clinicians can therefore misdiagnose their patient with acute kidney injury when the serum creatinine is elevated as a consequence of urine being present in the peritoneal space. This is a case report of a 62-year-old male with pseudo-renal failure following intraperitoneal bladder rupture after a fall face-forwards three hours previously. The fall was due to icy conditions outside and no preceding symptoms were reported. He presented to the Accident and Emergency department with abdominal pain and no other positive symptoms. The patient had a good World Health Organisation (WHO) performance status with a background of hypertension, diabetes, and hypercholesterolemia. The bedside examination of the patient revealed a distended, abdomen with peritonitis. There were no signs of urogenital trauma. Blood testing revealed a low estimated glomerular filtration rate (eGFR) and raised creatinine (eGFR of 7 millilitres/minute and creatinine of 658 micromoles/litre). Computerised tomography examination of the abdomen and pelvis (CTAP) revealed free fluid within the peritoneal cavity and an irregular bladder wall. A CT cystogram and consultation with urology led to the diagnosis of intraperitoneal bladder rupture. The patient's renal function from an initial set of blood tests was reduced. This was not a true impairment in renal function but rather a complication secondary to extravasation of urine in the intraperitoneal space, ie., pseudo renal failure. This supposed impairment in renal function had numerous implications. It affected the choice of antibiotics; amoxicillin and gentamicin were given at a reduced dose due to the patient's renal function and the patient was prepared for operation theatre. The patient's blood creatinine was falsely elevated at 658 micromoles/litre due to the diffusion of creatinine from the free urine in the peritoneal space into the blood. This painted a false image of renal failure and protracted the clinical decision-making process. Relatively simple measures like an ascitic tap could have helped to differentiate this from a true acute kidney injury and could have resulted in quicker and more effective treatment of this patient. The patient went on to have bladder repair under urology. His follow-up cystogram four weeks post-operation did not show any leak.

Pheochromocytoma is a rare adrenal tumor characterized by the secretion of catecholamines and vasoactive peptides. It can cause a catecholaminergic storm and lead to acute coronary syndromes. We present the case of a 53-year-old man, without any medical history, who arrived to the hospital following a spinal trauma due a fall. He presents back and retrosternal pain, with a clinical status of acute pulmonary edema, sinus tachycardia with left bundle branch block, left ventricular apical ballooning with depressed systolic function. Blood tests show a very important increase of Troponin and transaminases. A contrast chest-abdomen CT highlighted a right adrenal solid mass, with a diameter of 78mm, partial capsular laceration, compression of the inferior vena cava and the hepatic parenchyma. The clinical condition of the patient rapidly worsens from a respiratory and hemodynamic point of view, with cardiogenic shock, anuria and sepsis, refractory to all the medical treatments, until the patient died. The autopsy confirmed that the abdominal mass was a pheochromocytoma, broken after the trauma suffered. The resulting catecholaminergic storm caused a myocardial ischemia with Takotsubo syndrome, with cardiogenic shock. This unfortunate case confirms the pheochromocytoma as important risk factor for the onset of Takotsubo syndrome, and the how dramatic and severe a catecholaminergic storm can be.

Review
Teratogenic agents have been shown to have drastic and detrimental effects on fetuses if exposed to the agent during uterine life. The most sensitive time for a developing fetus is during the first trimester, and teratogenic exposure during this time can lead to severe deformities in the fetus. The Food and Drug Administration has categorized teratogenic agents based on the severity of their effect on the fetus; these categories include A, B, C, D, and X. Category A is the safest, with the most dangerous, and highly contraindicated in pregnant patients being Category X. This review article will discuss the teratogenic agents leflunomide, isotretinoin, thalidomide, warfarin, tetracycline, and angiotensinogen-converting enzyme inhibitors. Leflunomide can cause cranioschisis, exencephaly, and vertebral, head, and limb malformations. Isotretinoin's main teratogenic effects include central nervous system malformations, hydrocephalus, eye abnormalities, cardiac septal defects, thymus abnormalities, spontaneous abortions, and external ear abnormalities. Thalidomide has been shown to cause limb deformities, bowel atresia, and heart defects when the embryo is exposed to the agent during development. Warfarin can lead to spontaneous abortion and intrauterine death, as well as nasal hypoplasia, hypoplasia of extremities, cardiac defects, scoliosis, and mental retardation when exposed in utero. Tetracycline's teratogenic effects include gastrointestinal distress, esophageal ulceration and strictures, teeth discoloration, hepatotoxicity, and calcifications. Angiotensinogen-converting enzyme inhibitors can cause skull hyperplasia, anuria, hypotension, renal failure, lung hypoplasia, skeletal deformation, oligohydramnios, and fetal death. Teratogenic effects can be avoided if the pregnant patient is educated on the teratogenic effects of these agents.

Diquat is a herbicide that can have deleterious effects on the kidneys, liver, heart, lungs, and central nervous system on ingestion. Diquat poisoning-associated rhabdomyolysis has rarely been reported. We describe two cases of diquat poisoning with acute renal failure, myocardial damage, and rhabdomyolysis. Case 1: A 17-year-old man experienced anuria after ingesting ~200 mL of diquat 16 h prior. On admission, his creatinine (400 μmol/L), urea (11.7 mmol/L), creatine kinase (2,534 IU/L), and myohemoglobin (4,425 ng/mL) concentrations were elevated. Case 2: An 18-year-old woman who ingested ~200 mL of diquat 5.5 h prior to admission had normal creatinine, urea, and creatine kinase concentrations. Eleven hours after ingestion, she developed anuria with elevated creatinine (169 μmol/L) concentration; her creatine kinase (13,617 IU/L) and myohemoglobin (>3,811 ng/mL) concentrations were remarkably elevated 24 h after ingestion. Both patients also had elevated aminotransferase and myocardial enzyme concentrations. After undergoing hemoperfusion and hemofiltration, blood diquat concentrations in cases 1 and 2 on admission (16/6 h after ingestion), after hemoperfusion (20/11 h after ingestion), and after 8 h of hemofiltration/8 h of hemofiltration and 2 h of hemoperfusion (29/21 h after ingestion) were 4.9/9.1, 3.4/5.4, and 1.5/1.2 μg/mL, respectively. Severe diquat poisoning can cause acute kidney failure and rhabdomyolysis. Rhabdomyolysis may induce myocardial injury, aggravating kidney damage, and also increase transaminase concentration. Hemoperfusion and hemofiltration could be effective treatments for eliminating diquat in the blood.
