A RETROSPECTIVE ANALYSIS OF HISTOPATHOLOGICAL SPECTRUM OF LESIONS IN NEPHRECTOMY SPECIMENS IN A TERTIARY CARE CENTRE

Abstract

Background: Kidneys can be involved in various pathological processes. Nephrectomy is a common procedure in urological practice. Indications for nephrectomy can display geographical differences in different countries around the world with different urological causes. The aim of the study was to analyse the various lesions in nephrectomy specimens in a tertiary care hospital in Kurnool, Andhra Pradesh, South India and also to know the frequency of lesions according to the age, gender and histology. Materials and Methods: It is a retrospective study, done over a period of 13 years from June 2007 to March 2020 which included 132 nephrectomy cases. Patient information such as age, gender, clinical diagnosis, radiological data such as USG and CT results, gross morphology and microscopic data were recorded from the available data. Results: Of 132 nephrectomy specimens, 55 (41.66%) were males and 77 (58.34%) were females. The mean age was 40.46 years. 99 (75%) nephrectomy specimens showed ‑ non‑neoplastic lesions and 33 (25%) showed neoplastic lesions. The most common non‑neoplastic lesions were chronic pyelonephritis in 62 (46.96%) patients, followed by tuberculous pyelonephritis in 20 (15.15%) patients. RCC (n = 27) was the most common neoplastic lesion. Conclusion: Chronic pyelonephritis remains the most common non-neoplastic cause of nephrectomy. RCC is the most common neoplastic cause of nephrectomy. Tuberculosis has a high incidence in developing countries. Awareness of renal TB is required for the physicians, to suspect this disease in patients with unexplained urinary tract abnormalities, particularly in those with any immunosuppression and those coming from TB-endemic areas.
