Open Journal of Nephrology (OJNeph) , 2015, DOI: 10.4236/ojneph.2015.52010
Abstract: Background: Kidney biopsy is one of the most important tools in the assessment of kidney disease. Knowing the histopathology is important for immediate clinical management. It helps in predicting the long term prognosis and in planning for prevention of chronic kidney disease. Methods: This is a cross section study of percutaneus biopsies of the native kidneys of patients, who presented to the Aga Khan University Hospital Karachi Pakistan, over ten year period from 2003 to 2012. Age range was 16 to 77 years. Results: Total number of 435 biopsies were included in the study. The most common histopathological findings, regardless of the indication of biopsy were Tubulo Interstitial Nephritis in 15 percent, followed by Membranous Nephropathy in 12 percent, Focal Segmental Glomerulosclerosis in 8 percent and Membrano Proliferative Glomerulonephritis also in 8 percent. Conclusion: This study will help in better understanding the spectrum of renal disease in Pakistan. It will guide the clinician in the management and provide a data base or a starting point for the researchers for conducting the controlled and population base studies.

Abstract: We report a rare case of a papillary renal cell carcinoma seeding along a percutaneous biopsy tract detected at the time of partial nephrectomy in a 51-year-old man with a 3.5 cm renal mass discovered on computed tomography scan (CT scan). Although renal percutaneous biopsy is now considered as an accurate and safe technique to provide valuable diagnostic information for indeterminate renal lesions, some inherent risks have been reported to associate with this procedure. One of the risks is tumor needle tract seeding, which is a very rare complication of renal percutaneous biopsy. Our well-documented case report could provide some useful information to evaluate the prognosis of patients with tumor seeding along a percutaneous biopsy tract.
Arteriovenous Fistula Complicating Transjugular Renal Biopsy  [PDF]

Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100428
Abstract: Percutaneous renal biopsy with sonographic guidance is the standard by which renal tissue is sampled. In patients with uncorrectable coagulopathy or other contra-indication, percutaneous biopsy may not be feasible and a transvenous approach is preferred. This method limits the risk of bleeding complications as tissue is obtained endovascularly without transgression of the renal capsule. Arteriovenous fistula (AVF), a well-documented complication of percutaneous biopsy, has yet to be reported when done from a transvenous route. This report describes a case of iatrogenic arteriovenous fistula following transjugular renal biopsy necessitating selective arterial embolization. Clinical features are reviewed in addition to spot fluoroscopic images from transarterial coil embolization of the AVF.

Abstract: Kidney biopsy is a diagnostic technique allowing in vivo collection of kidney tissue material for a histopathological examination, which makes it possible to diagnose disorders in the normal organ structure. The most common biopsy used for a sample collection is oligobiopsy. Renal biopsy is a safe and very useful diagnostic method allowing direct evaluation of disorders in the normal kidney structure and precise determination of the disease process nature with regard to qualitative and quantitative changes.

Normal kidney aging is related to tissue and functional changes that make older patients very vulnerable to environmental modifications. Numerous factors can accelerate the impairment of renal function during aging. It was a single-center retrospective study extending over a period of 30 years from 1984 to 2014 and includes patients older than 65 years, hospitalized for nephropathy requiring renal biopsy and monitored in our service. There were 6 men and 7 women with an average age of 69.38 ± 4.5 years. Mean serum creatinine was 267.15 ± 124 mmol/l. Eleven patients had renal failure. Histological lesions were: Extramembranous glomerulonephritis (EMGN): 1 case, focal segmental glomerular sclerosis (FSGS): 3 cases, membranoproliferative glomerulonephritis (MPGN): 1 case, IgA nephropathy: 1 case, glomerulonephritis with IgG4 fibrillar deposits (GN IgG4): 1 case, diabetic nephropathy: 2 cases, myeloma-associated tubulopathy: 1 case, acute tubular necrosis: 1 case, acute interstitial nephritis: 1 case, vascular nephropathy: 1 case. Kidney disease will increasingly become a geriatric illness. Nephrologists are encountering a growing group of elderly patients with diminished equation for estimated glomerular filtration rate (eGFR) that require evaluation and management.

Abstract: 356 kidney biopsies performed to 346 patients from october 31, 1988, to october 31, 1999, were analyzed. it was proved that 66.5 % (230/346) had primary glomerulopathy and that iga primary nephropathy (igapn) accounted for 7.2 % (25/346) of the total of biopsies performed and for 10.9 % (25/230) of primary glomerular diseases. the following variables were analyzed: age, sex, race, blood pressure readings, persistent proteinuria, histological pattern and kidney function. average age was 23.8 ± 7.6. it was found that the white patients (18/25; 72.0 %) and the males (in a ratio of 2.6:1) were the most affected. at the end of the study, 20 % of the patients (5/25) with iganp presented different degrees of renal failure, with a very significant statistical association (p < 0.01) when the kidney dysfunction was related to maintained arterial hypertension, a histological pattern of diffuse mesangial proliferative glomerulonephritis (dmpgn) and interstitial fibrosis in the histological study obtained by kidney biopsy. it was concluded that the mantained presence of aht, a histological pattern of dmpgn and the finding of interstitial fibrosis represented a poor prognosis in the evolution of the disease.

Abstract: Background: The gold standard for investigating the cause of renal graft dysfunction is renal biopsy. How-ever, as this procedure is invasive and has inherent risks, its safety must be established. Objective: To determine the safety of percutaneous renal biopsy in pediatric orthotopic renal transplanta tion. Methods: Percutaneous renal biopsies performed on pediatric orthotopic renal transplants in a single cen ter between 1987 and 2010 were studied. Biopsy specimen adequacy and post-procedure complications were reviewed by prospectively collected data. Results: A total of 54 ultrasound “real-time” guided biopsies in 25 patients were performed. Minimum specimen adequacy was achieved in 98% of biopsy specimens. No major complications were identified; 6% of patients developed minor complications—e.g., grade 3 macroscopic hematuria that did not require intervention. Conclusion: Percutaneous renal biopsies using “real-time” ultrasound guidance on pediatric orthotopic kid-ney transplants is safe.

Abstract: Introduction. Different pathological changes of kidney transplants have similar symptoms, thus differential diagnostic is sometime difficult. The important information that may help to set correct diagnose can be obtained from the kidney transplant biopsy followed by pathohistological investigation. Aim of the study. The aim of this study is to demonstrate the role of biopsy in differential diagnostics of kidney graft pathology. Materials and methods. 109 kidney graft biopsies were performed at the Latvian Transplantation Centre in 2007: 20 were protocol biopsies and 89 were performed according to indications (graft dysfunction). All biopsies were performed under USS control followed by pathohistological investigations of the material obtained. Morphological changes were evaluated accordingly to the Banff 97 classification. Results. The morphological findings were as follows: borderline changes - 8 cases (7.34%); acute cellular rejection - 80 cases (73.4%); acute humoral rejection - 1 case (0,92%); hronic graft nephropathy - 27 cases (24.8%); tubolointersticial nephritis - 36 cases (33%); apostematous nephritis - 1 case (0.92%). We observed mild hematuria in only 2 patients after biopsy which stopped spontaneously in a few days. Conclusions. Kidney graft biopsy followed by pathohistological investigation of the material obtained is a precise and sensitive method in the diagnostic process of pathological changes of the graft with a small rate of complication.
