We present the treatment of lower pole stones of a 62-year-old male patient with a history of open partial nephrectomy due to renal angiomyolipoma and renal stones. He was successfully treated with micropercutaneous nephrolithotomy technique under spinal anesthesia in spite of fibrotic and scar tissue due to previous open surgery. The patient was stone-free and was discharged after a 24-hour ho...

Erythropoietin (Epo) is an indispensable erythropoietic hormone primarily produced from renal Epo-producing cells (REPs). Epo production in REPs is tightly regulated in a hypoxia-inducible manner to maintain tissue oxygen homeostasis. Insufficient Epo production by REPs causes renal anemia and anemia associated with chronic disorders. Recent studies have broadened our understanding of REPs from...

the prevalence of vesicoureteral reflux (vur) among siblings of children with vur has been reported to be from 4.7% to 51%. the incidence of vur in the general population is less than 1% but it is high in risk groups. in a prospective study we started identifying the incidence and severity of vur and renal parenchymal lesions in the siblings of patients known to have urinary tract infection (ut...

background and purpose: posterior urethral valve (puv) is one of the most severe urinary tract anomalies presenting as antenatal hydronephrosis that could lead to severe dilatation and functional impairment of one or both kidneys. the aim of this study was to analyze our experience on patients with a diagnosis of puv. materials and methods: in this prospective study neonates with a diagnosis of...

A 44-year-old man underwent live related allograft renal transplantation for stage V chronic kidney disease secondary to unknown cause three years earlier. The immunosuppressive regimen consisted of cyclosporine, azathioprine, and prednisolone. The nadir creatinine level of 1.5 mg/dL was reached one week postoperatively. This remained stable for 30 months when the serum level of creatinine bega...

Background Delayed gadolinium enhancement (Gd-DE) is widely used to detect scar formation following myocardial infarction (MI) [1], but cannot be performed in patients with renal impairment. Here we use the tractographic propagation angle (PA), a novel index derived from 3D diffusion tensor MRI (DTI), to detect changes in myocardial fiber architecture post-MI [2]. We compare image segmentation ...

The aim of this study was to analyze our experience on patients with a diagnosis of PUV. Materials and Methods: In this prospective study neonates with a diagnosis of...
