A Histomorphological Study of Nephrectomy Specimens in Rural Rajasthan-A Population Based Study

BACKGROUND Nephrectomy brings in relief to patients from various chronic and life threatening diseases and in some cases makes way for renal transplant. Renal cell carcinoma accounts for 3% of all cancer deaths. Staging and grading remain the most useful indicators. Hence the present study was undertaken to become familiar with the morphological features and to explore, elucidate and document the kidney lesions at nephrectomy. We wanted to study the spectrum of renal lesions post nephrectomy, obtain the overall frequency, the age and sex incidence of various lesions at nephrectomy along with detailed histomorphology study of various lesions encountered in nephrectomy specimens and evaluate the histomorphological study of renal tumours including the classification of cell type, architectural pattern and grading. METHODS This prospective study was done on 85 nephrectomy specimens received in the department of pathology, N.I.M.S. Medical College, Jaipur, over a period of three years (2016 to 2019). RESULTS Of these 85 nephrectomy specimens, 44 cases (51.7%) were neoplastic and remaining 41 cases (48.2%) were non-neoplastic. CONCLUSIONS The youngest patient was 40 days and oldest was 75 years. Chronic pyelonephritis was the commonest non-neoplastic lesion. Renal cell carcinoma was the commonest tumour and was commoner in males with clear cell variant being the most frequent. Monophasic Wilms tumour was the commonest neoplastic lesion in the paediatric population.
