1/26. hypertension due to renal tuberculosis: assessment by renal vein renin sampling.A 36-year-old man with asymptomatic hypertension was shown to have destruction of the right kidney due to renal tuberculosis. The peripheral renin level was normal, but renal vein renin sampling showed predominant renin secretion from the right kidney both in basal samples and after acute stimulation of renin release with intravenous diazoxide. nephrectomy has resulted in marked reduction of blood pressure without treatment one year after operation. The findings support the predictive value of renal vein renin sampling when hypertension is associated with renal parenchymal disease, even when peripheral renin is normal.- - - - - - - - - - ranking = 1keywords = kidney (Clic here for more details about this article) |
2/26. Replacement lipomatosis related to renal tuberculosis: imaging findings in one case.Replacement lipomatosis of the kidney in a case of long-standing renal tuberculosis is reported. The radiologic and pathologic findings are described and the differential diagnosis is discussed. A hypothesis is given to explain the association of renal tuberculosis and replacement lipomatosis of the kidney.- - - - - - - - - - ranking = 1keywords = kidney (Clic here for more details about this article) |
3/26. pyonephrosis due to salmonella cholerae-suis variant kunzendorf.A patient with unilateral infection of the kidney due to Salm. cholerase-suis is presented. Long-term treatment with ampicillin was of no avail. nephrectomy terminated the infection. The extirpated kidney showed severe obstruction, stones and tissue damage.- - - - - - - - - - ranking = 1keywords = kidney (Clic here for more details about this article) |
4/26. Renal macronodular tuberculoma: CT and MR findings in an asymptomatic patient.We present the case of a 50-year-old man with a solitary mass lesion in the right kidney. Characteristics on ultrasound were a thick irregular hypoechoic wall and a slightly hyperechoic center. Computed tomography depicted the lesion as spontaneously hyperdense at its base. After administration of intravenous iodinated contrast only partial enhancement in the peripheral wall was seen. On MR imaging the lesion was hypointense on T1-weighted images, and T2-weighted images demonstrated a thick irregular hypointense peripheral wall and an intralesional fluid debris level. gadolinium-chelates were not administered.- - - - - - - - - - ranking = 0.5keywords = kidney (Clic here for more details about this article) |
5/26. Radicular symptoms in tuberculosis. A case report.A case of tuberculous radiculitis in the lumbosacral region resulting in flaccid paresis of the lower limbs is presented. The primary site of tuberculosis was the intestine. Hematogenic dissemination resulted in organ tuberculosis of the third lumbar vertebra and left kidney. The infection spread locally into the lumbosacral dura and nerve roots. A decline in general immunological resistance lead to fatal dissemination of the disease into the meninges, lungs, liver, left adrenal and right kidney. Differential diagnostic problems, especially the guillain-barre syndrome, are discussed.- - - - - - - - - - ranking = 1keywords = kidney (Clic here for more details about this article) |
6/26. Clinics in diagnostic imaging (97). Right renal tuberculous autonephrectomy.A 50-year-old man presented with recurrent episodes of right flank pain and dysuria for many years. Abdominal radiograph and intravenous urography showed extensive right renal parenchymal calcification in a lobar distribution and a non-functioning right kidney, characteristic of end-stage tuberculosis. The pathology, clinical manifestations, and radiological findings of renal tuberculosis are discussed.- - - - - - - - - - ranking = 0.5keywords = kidney (Clic here for more details about this article) |
7/26. Successful kidney re-transplantation in a patient with previous allograft kidney tuberculosis.opportunistic infections, and in particular tuberculosis (TB), carry substantial morbidity and mortality in solid organ transplant recipients. We report a 39-year-old man who underwent a cadaveric renal transplant. Three months postoperatively, he was diagnosed to have tuberculous infection of his graft kidney manifested as fever and renal impairment. The diagnosis was confirmed by renal biopsy, which showed granuloma formation and positive stain for acid-fast bacilli (AFB). His systemic symptoms responded well to a complete course of anti-tuberculous therapy, but his renal function continued to deteriorate. Graft nephrectomy was performed and the patient underwent a second kidney transplant 1 year later. He remained well and asymptomatic thereafter. No signs of recurrence of tuberculous infection were noted up until the present time. This case illustrates that TB remains an important threat to transplant recipients. Although reactivation of dormant TB is the usual mode of infection, acquisition from the donor graft is also possible. The latter may account for the infection in our case, as our patient had a negative tuberculin skin test and normal chest radiograph prior to transplant. The identification of AFB in the kidney graft less than 3 months postoperatively also suggested that causal relationship. While diagnosing TB in post-transplant recipients is difficult and may require renal biopsy, as in our case, treatment on the other hand is no different from the standard protocols. However, no consensus has been reached on the safety of re-transplantation. Also, the need for graft nephrectomy and chemoprophylaxis remains unclear.- - - - - - - - - - ranking = 5.5keywords = kidney (Clic here for more details about this article) |

9/26. Tubercular mass mimicking a tumour in a horseshoe kidney: a unique presentation.Tuberculosis of the kidney is quite a common disease and various forms of presentation are described. In most cases the disease results in atrophy, calcification or necrosis of parenchyma. The kidney is not generally palpable except occasionally in case of hydronephrosis; caused by upper ureteral structure. Renal tuberculosis presenting as large solid mass has not yet been reported. We present a case of solid renal mass of tubercular etiology. diagnosis and management are presented.- - - - - - - - - - ranking = 3keywords = kidney (Clic here for more details about this article) |
10/26. The role of ultrasound and echo-color Doppler in the diagnosis and follow-up of tuberculosis of the transplanted kidney.Tuberculosis is still a relatively frequent, serious disease developing in kidney transplant patients, having an overall incidence estimated to range between 0.35 and 15%. The disease often presents with unusual clinical manifestations, partly due to the more frequent extra-pulnipnary localizations. We describe the clinical case of a 49-year-old patient who had undergone a bilateral kidney transplant from a 70-year-old donor. About 8 months after the transplant he developed fever and raised serum creatinine values were found, together with subcutaneous abscesses in the groin, along both surgical wounds, and on the external genital area. Ultrasound and radiographic imaging demonstrated the presence of multiple intra-abdominal abscesses, localized at the level of the spleen hilus, of the left transplanted kidney and the right parietocolic retroperitoneum. Positive cultures were obtained to mycobacterium tuberculosis and the patient was administered anti-tubercular treatment with Etambutol, Isoniazide, and rifabutin. The initially prescribed immune suppressive treatment (Corticosteroids, Cyclosporin and Micophenolate) was progressively reduced to only 5 mg/die of prednisone. After 6 months from the start of the anti-tubercular treatment the patient showed an improvement of the clinical and radiological picture, as well as preservation of the renalfunction.- - - - - - - - - - ranking = 3.5keywords = kidney (Clic here for more details about this article) |
