<i>Background</i> The standard treatment of T1 renal cell carcinoma is (partial-) nephrectomy. For patients where surgery is not the treatment of choice, for example in the elderly, in case of severe comorbidity, inoperability or refusal of surgery, alternative treatment options are available. These treatment options include active surveillance, radiofrequency ablation, cryoablation, microwave ablation or stereotactic body radiotherapy. In the present overview, the efficacy, safety and outcome of these different options are summarized, particularly focusing on recent developments...

BACKGROUND: Low birth weights have been associated with a reduction in nephron number with compensatory hypertrophy of existing glomeruli. The impact of donor birth weight as an estimate of nephron number on allograft function, however, has not been examined. METHODS: We collected donor birth weight, kidney weight, and volume from 91 living kidney donor-recipient pairs before nephrectomy and after 12, 36, and 60 months. Nephron number was calculated from donor birth weight and age...

The kidney is a complex organ with more than 20 types of specialized cells that play an important role in maintaining the body's homeostasis. The epithelial tubular cell is formed during embryonic development and has little proliferative capacity under physiological conditions, but after acute injury the kidney does have regenerative capacity. However, after repetitive or severe lesions, it may undergo a maladaptation process that predisposes it to chronic kidney injury. Regenerative medicine includes various repair and regeneration techniques, and these have gained increasing attention in the scientific literature...

REVIEW
Roland Schmitt, Anette Melk
Epidemiologic, clinical, and molecular evidence suggest that aging is a major contributor to the increasing incidence of acute kidney injury and chronic kidney disease. The aging kidney undergoes complex changes that predispose to renal pathology. The underlying molecular mechanisms could be the target of therapeutic strategies in the future. Here, we summarize recent insight into cellular and molecular processes that have been shown to contribute to the renal aging phenotype.The main clinical finding of renal aging is the decrease in glomerular filtration rate, and its structural correlate is the loss of functioning nephrons...

Chronic congestive heart failure (CHF) is a complex disorder characterized by inability of the heart to keep up the demands on it, followed by the progressive pump failure and fluid accumulation. Although the loop diuretics are widely used in heart failure (HF) patients, both pharmacodynamic and pharmacokinetic alterations are thought to be responsible for diuretic resistance in these patients. Strategies to overcome diuretic resistance include sodium intake restriction, changes in diuretic dose and route of administration and sequential nephron diuretic therapy...

Tubulointerstitial fibrosis (TIF) is a prominent factor in the progression of chronic kidney disease (CKD) regardless of etiology. ErbB4 expression levels were inversely correlated to renal fibrosis in human fibrotic kidneys. In both unilateral ureteral obstruction (UUO) and ischemia reperfusion injury followed by uninephrectomy (IRI/UNx) mouse models, expression levels of ErbB4 were elevated in the early stage of renal injury. Using mice with global ErbB4 deletion except for transgenic rescue in cardiac tissue (ErbB4-/-ht+), we determined that UUO induced similar injury in proximal tubules compared to wild-type mice but more severe injury in distal nephrons...

INTRODUCTION: We evaluated whether nephron sparing surgery (NSS) combined with meticulous suturing of the cut stump under clamping with cooling is beneficial for oncological outcomes and also assessed the relationship between cold ischemia time and deterioration of renal function. METHODS: One hundred and six patients with renal cell carcinoma (RCC) were subjected to this procedure. Oncological outcomes and renal function according to the estimated glomerular filtration rate (eGFR) and the tubular excretion rate on renoscintigraphy before and at 12 months after surgery were evaluated...

Open studies have definitely and repeatedly favoured nephron-sparing surgery in improving overall, cancer-specific, and cardiac disease-specific survival in cases with a normal contralateral kidney. However, the only randomised clinical trial could not confirm this superiority of nephron-sparing surgery over radical nephrectomy.

Angiotensin II type 2 receptor (AT2 R) deficiency in AT2 R knockout (KO) mice has been linked to congenital abnormalities of the kidney and urinary tract; however, the mechanisms by which this occurs are poorly understood. In this study, we examined whether AT2 R deficiency impaired glomerulogenesis and mediated podocyte loss/dysfunction in vivo and in vitro. Nephrin-cyan fluorescent protein (CFP)-transgenic (Tg) and Nephrin/AT2 RKO mice were used to assess glomerulogenesis, while wild-type and AT2 RKO mice were used to evaluate maturation of podocyte morphology/function...

Cells lining the proximal tubule (PT) have unique membrane specializations that are required to maintain the high capacity ion transport and endocytic functions of this nephron segment. PT cells in vivo acutely regulate ion transport in response to changes in glomerular filtration rate (GFR) to maintain glomerulotubular balance. PT cells in culture upregulate endocytic capacity in response to acute changes in fluid shear stress (FSS); however it is not known whether GFR modulates PT endocytosis to enable maximally efficient uptake of filtered proteins in vivo Here we show that cells cultured under continuous FSS develop an expanded apical endocytic pathway as well as increased endocytic capacity and lysosomal biogenesis...

INTRODUCTION: The renal nephrometry scoring (RNS) system enables prediction the feasibility of nephron-sparing surgery (NSS) in renal masses. There is insufficient data regarding the outcome of robot-assisted NSS in tumors with RNS ≥10. We reviewed the trifecta outcomes of patients undergoing robotic NSS with high RNS and compare it with tumors of low and intermediate RNS. MATERIALS AND METHODS: Our prospectively maintained data of all robot-assisted NSS were reviewed, and those with RNS of ≥10 were identified...

Preterm birth occurs in approximately 10% of all births worldwide. Preterm infants have reduced nephron numbers at birth in proportion to gestational age, and are at increased risk of neonatal acute kidney injury as well as higher blood pressure, proteinuria, and chronic kidney disease later in life. Rapid catch-up growth in preterm infants, especially if resulting in obesity, is a risk factor for end-stage kidney disease among children with proteinuric renal disease. Preterm birth, however, is a risk factor not only for the infant because mothers who deliver preterm have an increased risk of having subsequent preterm deliveries as well as hypertension, cardiovascular disease, and renal disease later in life...

Primary hypertension continues to be one of the main risk factors for cardiovascular disease worldwide. A stable intrauterine environment is critical for the future development and health of the fetus. The developing kidney has been found to be especially vulnerable during this time period, and epidemiological studies have demonstrated that an adverse in utero environment is associated with an increased risk of hypertension and chronic kidney disease. Macro- and micronutrient deficiencies as well as exposure to tobacco, alcohol, and certain medications during gestation have been shown to negatively impact nephrogenesis and reduce one's nephron number...
