Xanthogranulomatous pyelonephritis is a rare disease characterised by the replacement of normal renal parenchyma by foamy macrophages. The only treatment for this type of pyelonephritis is of a surgical nature with partial or total nephrectomy. The occurrence of xanthogranulomatous pyelonephritis during pregnancy is a rare event (with only 6 cases described in the literature). We report a case of xanthogranulomatous pyelonephritis in a 32-week pregnant woman associated with hepatic dysfunction.

e16581 Background: Partial nephrectomy (PN) is the standard therapy for small renal mass, despite various degree of ischemia reperfusion injury (IRI) is always inevitable as the renal artery is usually clamped during PN. In mouse IRI model, unilateral renal artery clamped for 21 minutes results to sever kidney fibrosis in one year. However, what happened to the preserved renal parenchyma after several years since PN is still a mystery. The aim of the study is to compare the pathological chronic kidney disease (CKD) score of normal renal parenchyma before and several years after PN, as well as to explore the factors that associated with CKD score increase and GFR decline. Methods: We retrospectively collected the clinicopathologic data of 114 renal cell carcinoma (RCC) patients who underwent PN and subsequent radical nephrectomy (RN) due to tumor recurrence in 19 Chinese centers and Cleveland clinic. Macroscopic normal renal parenchyma was sampled at least 5 mm away from the tumor border in PN specimen and at distal portion of the kidney in RN specimen. Pathological CKD score is a summary of glomerular, tubular, interstitial, and vascular score. MDRD2 equation was used to estimate the glomerular filtration rate (GFR). Predictive factors for CKD score increase were evaluated by logistic regression. Results: A total of 64 patients that have all the required data were included in the analysis. The median duration warm ischemia (n = 41) and hypothermia (n = 23) were both 23 min. In a median interval of 2.44 years, the CKD score arose in 73.4% (47/64) patients, with 45.3% (29/64) cases increased by ≥3. Even so, no kidney fibrosis was observed in this cohort including in those with extend warm ischemia (≥45min). There was no significant difference in the change of CKD score during patients with different ischemia time and type. However, patients with comorbidities such as hypertension, diabetes mellitus or CKD (HTN/DM/CKD) showed higher rate and extent of CKD score increase. In multivariate analysis, HTN/DM/CKD was found to be an independent predictor for the CKD score increase [OR:4.24 (1.23-14.64)]. However, the decline of GFR was mild and analogous between patients with or without CKD score increase (23.03±22.53ml/min/1.73m2 vs. 24.27±21.79ml/min/1.73m2, p = 0.856). Conclusions: In majority, preserved renal parenchyma after PN suffered pathological deterioration. Ischemia time and type seem to have limited impact on the change of CKD score of preserved renal parenchyma during PN. Patients with HTN/DM/CKD have higher risk of CKD score increase in despite of similar mild GFR deterioration.
