Background: Frozen section is a commonly used tool for intraoperative consultation giving valuable information for patient management. Analysis of diagnosis during frozen section and subsequent permanent section allows the pathologist to review the diagnostic accuracy. Materials and methods: In this 2-year retrospective study, 66 tissues received for intraoperative consultation were studied with the corresponding permanent sections on analysis. The diagnosis was either concordant or discordant. The diagnostic accuracy, sensitivity, and specificity were calculated. Results: 65 of 66 cases had a concordant diagnosis on frozen sections and permanent sections. The diagnosis was discordant in one case due to the masking of a tumor by heavy inflammation. The diagnostic accuracy, sensitivity, and specificity were 98.48%, 96.8%, and 100% respectively. Conclusions: The results of our study compared well with those of other institutions, thereby emphasizing the value of frozen sections as a valuable test for intraoperative surgical consultation.

BACKGROUND Nephrectomy is a common procedure in surgical practice. There are many indications for nephrectomy, non-neoplastic and neoplastic conditions. The common conditions being chronic pyelonephritis and renal tumours. A detailed and meticulous histopathological examination is essential to establish the diagnosis of lesions of kidney. MATERIALS AND METHODS It is a retrospective study for a period of two years from January 2015 to December 2016 at a tertiary care centre. 34 cases of nephrectomy specimens were analysed and data recorded. RESULTS Non-neoplastic lesions were constituting 47.05% (16) of cases and 52.94% (18) cases were neoplastic lesions. Lesions were more common in females with male:female ratio of 1:1.4. Both the lesions were common in age group of 41-50 years. CONCLUSION The prevalence of neoplastic lesions was more common than non-neoplastic lesions. The commonest indication for nephrectomy was chronic pyelonephritis followed by renal tumours. Histopathological examination in correlation with clinical and radiological features plays a great role in subcategorisation of lesions accurately to ensure better therapy.
