Xanthogranuomatous pyelonephritis (CP) is an aggressive form of interstitial nephritis, including purulentdestructive and proliferative processes in the kidney to form granulomatous tissue. The difficulty of diagnosis of CP, low illumination of this problem in the literature are the reason for the publication of even a single observation. The exact diagnosis of the disease can be established only with morphological examination and, as a rule, after surgical treatment. The clinical observation of the treatment of the child 15 years xanthogranulomatous pyelonephritis, inpatient Nizhny Novgorod regional children's teaching hospital. A boy M. at the age of 15 years entered the clinic of acute pyelonephritis (fever up to 38–39°С, abdominal pain and left side). From anamnesis it is known that at the age of one year the child was diagnosed with recurrent leukocyturia. Urological examination revealed hydronephrosis of the lower half of the double kidney on the left. At the age of 7 he was operated on (due to negative dynamics), reconstructive surgery was performed – prilohanochnaya pyeloplasty on the lower segment of the double kidney on the left. In the subsequent exacerbations of pyelonephritis was not. 6 years after hepatitis and kidney injury (contusion), there was a significant increase in dilation of the abdominal system of the lower segment of the left kidney with exacerbation of secondary pyelonephritis. According to intravenous urography, MSCT, MRI (performed to exclude Wilms tumor), the absence of the function of the lower segment of the kidney with a sharp increase in its size was determined. After the preoperative examination, the left kidney was examined, in which the signs of xanthogranulomatous pyelonephritis (renal tissue of bright yellow color), lower left heminephroureterectomy were found, the Diagnosis was confirmed by morphological examination. In the postoperative period, a cyst of the lower pole of the kidney was formed, cured by percutaneous drainage, sclerosing under ultrasound control, followed by recovery. Thus, this clinical case demonstrates the complexity of the diagnosis of CP, which often occurs under the mask of a variety of diseases, including acute pyelonephritis and kidney tumors. Reliable diagnosis of xanthogranulomatous pyelonephritis is possible only with the help of histological examination of pathological tissues.

A series of 12 cases of Wilms' tumor, in which the diagnosis was confirmed in all instances by examination of the gross or microscopic tissue, is reported, with a survival rate of 33.3%. Four patients are living and well, 4, 8, 10, and 15 years, respectively, after treatment. All recurrences appeared less than 10 months after treatment. The sex incidence, and the sex survival incidence were exactly equal. Six tumors were in the left kidney, and six in the right. Eight of the patients were under 2 years of age when first diagnosed and treated, and all were under 7 years. The history of breast or bottle feeding was irrelevant. In a large number of these and reported cases, the presence of the tumor was the first symptom, and in a considerable number the only symptom. This fact stresses the importance of careful physical examination of infants and young children, regardless of complaint, or of lack of it. The finding of calcification in the tumor is possibly a good prognostic sign. All three patients in whom calcification was noted in the tumor are living and well. Immediate removal of the tumor by transperitoneal nephrectomy, with postoperative radiation to the area, seems to be the advisable treatment.

Background. The study assessed whether measurement of urinary biomarkers of acute kidney injury could be helpful in diagnosing acute pyelonephritis and subsequent scarring. Method. Escherichia coli J96 (0.3 mL inoculum containing 1×109/mL) was directly injected into the renal cortex of 3-week-old female Sprague Dawley rats (n=20), with saline substituted in a control group (n=10). Following the injection, urine was collected 2, 7, 14, 28, and 42 days after injection. Urinary neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecule-1 (Kim-1), and interleukin-18 were quantitatively measured using enzyme-linked immunosorbent assay (ELISA). The levels of the biomarkers were adjusted for creatinine. Time course changes within a group or between the groups were compared. Correlation analysis was performed to understand the relationship between urinary levels and histological scarring. Results. Significantly elevated urinary NGAL was evident at two and seven days after injection, and Kim-1 was elevated at two days after injection. Receiver operating characteristic analyses confirmed the sensitivity of these markers at these times. No urinary marker at acute stage of APN was correlated with the amount of future scarring, negating their predictive value. Conclusion. Urinary NGAL and Kim-1 could be helpful in diagnosing febrile urinary tract infection in children.

Background: Genitourinary tract tumors in children are less common than in adults. Most of these tumors have different genetic backgrounds, clinical presentation, and oncologic behavior than their adult counterpart. As a result of low prevalence in children, some of the treatment approaches and recommendations are based on treatment experience in adult patients. However, thanks to scientific and technological development, survival rates have risen considerably. Objective: This paper presents a review of the principal features of the tumors involving the genitourinary tract in children and an update in genetic background, diagnosis, and treatment. Methods: A narrative review was performed on published literature about genitourinary tract tumors in pediatric patients. Papers presented in English and Spanish literature were reviewed. PubMed, Science Direct, and SciELO databases were used to collect information and present this article. Results: Kidney tumors are the most common type of genitourinary tumors in children. Among those, Wilms tumor represents the majority of cases and shows the successful work of clinical trial groups studying this tumor type. Other tumors involving the genitourinary tract in children include Rhabdomyosarcoma, Transitional cell carcinoma, Testicular, and Adrenal tumors. Conclusion: Genitourinary tract tumors in children represent significant morbidity and economic burden, so awareness in early diagnosis represents improvement in treatment, clinical and oncological outcomes.

ObjectiveObstruction release from urolithiasis can be delayed with a lack of suggested time for preventing the deterioration of renal function. The objective of this study was to investigate the effect of obstruction duration, concomitant acute kidney injury (AKI) or acute pyelonephritis (APN) during the obstruction on the prognosis of renal function.DesignRetrospective cohort study.Setting and participants1607 patients from a urolithiasis-related obstructive uropathy cohort, between January 2005 and December 2015.Outcome measuresEstimated glomerular filtration rate (eGFR) decrease ≥30% and/or end-stage renal disease (ESRD), and eGFR decrease ≥50% and/or ESRD, according to obstruction duration, AKI and APN accompanied by obstructive uropathy.ResultsWhen the prognosis was divided by obstruction duration quartile, the longer the obstruction duration the higher the probability of eGFR reduction >50% (p=0.02). In patients with concomitant APN or severe AKI during hospitalisation with obstructive uropathy, an eGFR decrease of >30% and >50% occurred more frequently, compared with others (p<0.001). When we adjusted for sex, age, hypertension, diabetes mellitus, APN, AKI grades and obstruction release >7 days for multivariate analysis, we found that concomitant APN (HR 3.495, 95% CI 1.942 to 6.289, p<0.001), concomitant AKI (HR 3.284, 95% CI 1.354 to 7.965, p=0.009 for AKI stage II; HR 6.425, 95% CI 2.599 to 15.881, p<0.001 for AKI stage III) and an obstruction duration >7 days (HR 1.854, 95% CI 1.095 to 3.140, p=0.001) were independently associated with an eGFR decrease >50%. Tree analysis also showed that AKI grade 3, APN and an obstruction duration >7 days were the most important factors affecting renal outcome.ConclusionsIn patients with urolithiasis-related obstructive uropathy, concomitant APN was strongly associated with deterioration of renal function after obstruction release. The elapsed time to release the obstruction also affected renal function.

Xanthogranulomatous pyelonephritis (XGP) is a rare entity and constitutes less than 1% of chronic pyelonephritis. A 71-year-old male was introduced to our department with general malaise and abnormal findings of computed tomography (CT). Abnormal findings of complete blood count and laboratory examination included an elevated WBC count and C-reactive protein. Urinalysis showed combined hematuria and pyuria, andEscherichia coliwas detected in urine culture. Abdominal CT revealed left hydronephrosis with staghorn renal calculi and thin cortex of the left kidney. Because of poor condition, the patient underwent construction of the left nephrostomy. After that, the remission of the inflammation was achieved. Several months after the construction, frequent obstructions of nephrostomy catheter because of turbid urine and intermittent fever elevation were observed. The patient and his family desired left nephrectomy despite his poor condition in general. Surgical dissection was very difficult due to fixed mass. Not long after that the patient died due to sepsis and cardiovascular failure. Microscopic findings of the left kidney revealed infiltration of lymphocytes and lipid-laden macrophages (xanthoma cells) corresponding to XGP.

Thyroid Axis

Thyroid hormones (TH) are essential for an adequate growth and development of the kidney. Conversely, the kidney is not only an organ for metabolism and elimination of TH, but also a target organ of some of the iodothyronines' actions. Thyroid dysfunction causes remarkable changes in glomerular and tubular functions and electrolyte and water homeostasis. Hypothyroidism is accompanied by a decrease in glomerular filtration, hyponatremia, and an alteration of the ability for water excretion. Excessive levels of TH generate an increase in glomerular filtration rate and renal plasma flow. Renal disease, in turn, leads to significant changes in thyroid function. The association of different types of glomerulopathies with both hyper- and hypofunction of the thyroid has been reported. Less frequently, tubulointerstitial disease has been associated with functional thyroid disorders. Nephrotic syndrome is accompanied by changes in the concentrations of TH due primarily to loss of protein in the urine. Acute kidney injury and chronic kidney disease are accompanied by notable effects on the hypothalamus–pituitary–thyroid axis. The secretion of pituitary thyrotropin (TSH) is impaired in uremia. Contrary to other non-thyroidal chronic disease, in uraemic patients it is not unusual to observe the sick euthyroid syndrome with low serum triodothyronine (T3) without elevation of reverse T3(rT3). Some authors have reported associations between thyroid cancer and kidney tumors and each of these organs can develop metastases into the other. Finally, data from recent research suggest that TH, especially T3, can be considered as a marker for survival in patients with kidney disease.

Abstract Introduction/Objective The histologic features of renal cell carcinoma (RCC) after immunotherapy are not fully established. We report the pathologic findings of one case of clear cell RCC after treatment with pembrolizumab which is a humanized monoclonal anti-PD1 antibody. Methods/Case Report 46-year-old man completed three cycles of pembrolizumab for recurrent basal cell carcinoma. A 5.0 cm mass was incidentally found within left kidney during staging CT scan. He subsequently had left radical nephrectomy. Pathologic examination of nephrectomy specimen identified one 5.0 cm, well-circumscribed, solid mass in the upper pole, confined to the kidney with predominantly hemorrhagic, focally golden-yellow soft cut surface. The remaining parenchyma appears unremarkable. The pelvicalyceal system is not dilated. Sections of tumor show predominance of foamy histiocytes, lymphoplasmacytic infiltrate, and scattered cells having pale or eosinophilic cytoplasm, conspicuous nucleoli and low nuclear: cytoplasm ratio. Cholesterol clefts and hemosiderin deposits are noted. The immunostaining profile highlights areas suspicious for viable tumor cells by using pan-keratin, CK8/18, EMA, CA9 and CD10. Focal positivity in the same area is noted by the stains of PAX 8 and AMACR. However, with numerous histiocytes, it is difficult to determine if the tumor cells are positive for Vimentin. Moreover CD 117 is negative in the tumor cells. Results (if a Case Study enter NA) NA Conclusion Differential diagnosis includes renal cell carcinoma and xanthogranulomatous pyelonephritis. The overall findings support a clear cell RCC affected by the immunotherapy. With immunotherapy-based combinations becoming standard of care in advanced malignancies, it makes the pathological diagnosis more challenging and difficult, especially for incidental tumors.
