Objectives: To determine for which tumors a percutaneous computed tomography (CT)-guided biopsy might be beneficial to distinguish between benign and malignant lesions. Methods: The author analyzed the international literature since 2000 that deals with biopsy of renal masses, which involved more than 1000 patients. He reports also on his own experience. Results: The accuracy of renal biopsy to...

BACKGROUND An adequate renal biopsy is essential for diagnosis and treatment of medical renal disease. OBJECTIVE We evaluated two initiatives to improve adequacy of renal biopsy samples at our centre. DESIGN Retrospective determination of renal biopsy adequacy. SETTING Queen Elizabeth II Health Sciences Centre. PATIENTS Patients undergoing medical renal biopsies. MEASUREMENTS Renal bi...

Renal biopsy remains the golden standard diagnosis of renal function deterioration. The safety in native kidney biopsy is well defined. However, it is a different story in allograft kidney biopsy. We conduct this retrospective study to clarify the safety of allograft kidney biopsy with indication.All variables were grouped by the year of biopsy and they were compared by Mann-Whitney U test (for...

BACKGROUND Renal biopsy remains the means by which definitive parenchymal kidney disease diagnoses are made. With the renal biopsy, the activity, progression and prognosis of renal parenchymal diseases can be studied with objectivity. We investigated the trend of renal histopathology request in a tertiary hospital in Nigeria over 31 years. OBJECTIVE To determine the trend of renal biopsy requ...

Background Chronic kidney disease is a global health concern, its detection and diagnosis in earlier stages is also a great challenge that can alleviate this burden. Kidney biopsy is important to establish histopathological patterns. But, it is invasive. We aimedto evaluate the correlation of renal resistive index (RI) measured by Doppler ultrasound with the prog...

Renal monoclonal immunoglobulin deposition disease (MIDD) is a rare defined by of light chains and/or heavy on basement membranes and vascular walls the kidney. We describe case 71-year-old woman with kidney failure secondary to lambda in association plasma cell dyscrasia. Her initial serum protein electrophoresis did not demonstrate protein, classic cast nephropathy was absent renal biopsy. Ho...

BACKGROUND Renal biopsy is not free from complications and patients who undergo this procedure are usually hospitalized to receive intensive care for several days after biopsy. In contrast, after this period, routine follow-up to detect biopsy-associated complications is rarely scheduled, unless the patient develops a clinical manifestation. We describe a case of marked enlargement of arteriove...

I read with great interest the case report by Abourbih and colleagues.1 In few last decades, the diagnosis of small renal masses (SRMs) has increased due to the routine use of imaging modalities.2 Small renal masses represent 48% to 66% of all renal cell carcinomas and only 1% of them will spread to distant metastasis.3 There is a need to biopsy SRMs to distinguish their behavior by radiologic ...

INTRODUCTION A clinical index that discriminates disease progression independent of histopathologic features may be valuable in the best timing of biopsy. OBJECTIVE This study addresses the question if a clinical index based on cortical echogenicity, renal length to body height ratio (KL/H), and serum creatinine levels predicts renal survival. METHODS The study enrolled 154 patients. Biopsy...
