Background: Percutaneous nephrolithotomy (PCNL) is performed on a routine basis for the rapid and efficient removal of large caliceal stones. After percutaneous puncture, rigid dilators or an inflatable balloon are used to dilate the nephrostomy tract to allow access to the collecting system for stone removal. Little is known of the acute impact of tract dilation procedures on renal function.

Materials And Methods: We compared renal hemodynamic and excretory function in female pigs immediately before and up to 5 hours after percutaneous nephrostomy (PCN) using sequential Amplatz dilators (N = 8) or Nephromax balloon inflation (N = 7) and control pigs with no PCN access (N = 8). We also examined renal function in patients undergoing PCNL.

Results: The two PCN procedures produced a renal lesion of comparable size and morphology, as well as similar changes in renal function. Glomerular filtration rate (GFR), renal plasma flow (RPF), and urinary sodium excretion (U(Na)V) were significantly reduced in Amplatz- and Nephromax-treated kidneys throughout the 5-hour observation period, by about 50%, 60%, and 80%, respectively. In control pigs, GFR and RPF remained stable and U(Na)V declined progressively to about 50% of baseline over the course of the experiment. The contralateral kidney showed changes in renal function similar to those in the PCN-treated or control kidney in all three groups. A retrospective analysis of 196 adults with normal renal function who underwent unilateral PCNL using the Nephromax balloon dilator revealed a significant increase in serum creatinine of 0.14 mg/dL at 1 day.

Conclusion: Both animal and human studies show that PCN is associated with an acute decline in renal function.

Background: Cardiac autonomic neuropathy (CAN) is a significant complication in chronic kidney disease (CKD), leading to increased morbidity and mortality. Early detection is essential for managing CKD patients effectively, especially those on hemodialysis. This study evaluated the prevalence CAN in CKD and diagnostic accuracy of Bellavere's Score in predicting CAN in CKD patients, including those undergoing hemodialysis.

Because acute kidney injuries (AKI) are one of the critical health problems worldwide, studies on the risk factors, mechanisms, and treatment strategies seem necessary. Glycerol (GLY), known to induce cell necrosis via myoglobin accumulation in renal tubules, is widely used as an AKI model. This study aimed to evaluate the protective effects of gallic acid (GA) against GLY-induced AKI.

Pseudohypoaldosteronism (PHA) is a rare disorder that mimics congenital adrenal hyperplasia (CAH). Renal type A1A of the disorder has a known gene mutation (NR3C2) and parents may be asymptomatic despite biochemical abnormalities. Meticulous interpretation of hormonal and biochemical data, and early liaison with endocrinology and renal teams are key in diagnosis.
