Abstract

BACKGROUND: Renal tumor biopsy is beneficial as it is capable of distinguishing between histological types of renal tumor; hence, it plays an important role in deciding the best therapy regimen. AIM: This study aims to evaluate the clinical experiences of renal biopsy in Cipto Mangunkusumo National Referral Hospital (RSCM), with both a percutaneous and open approach. It also aims to analyze the indications, results, intraoperative information, and complications of the two approaches. METHODS: This study was conducted using the retrospective cohort design; meanwhile, data were collected from RSCM from 1990 to 2019. The biopsy sample was taken using percutaneous and open renal biopsy, while comparative analysis was done between the two biopsy approaches. RESULTS: Data were collected from 33 patients that underwent renal biopsy from 1990 to 2019. Majority of the cases were diagnosed as unresectable renal tumor, while histological examination found clear cell carcinoma in most of the cases (73%). Furthermore, the open approach showed longer duration and higher blood loss compared to percutaneous technique with median 60 (30–120) versus 30 (5–60) min (p < 0.001) and 100 (5–650) versus 2 (1–5) ml (p < 0.001), respectively. In general, complications were reported to be low for both techniques. CONCLUSION: Based on the results, percutaneous renal biopsy has similar efficacy and complications rates in tumor sampling for histopathology together with open approach. However, there were significant differences in the duration and blood loss; hence, percutaneous biopsy is more favorable.
