ConclusionCompared with those who reported passing only one kidney stone, caffeine intake was independently and linearly associated with a higher risk of recurrent kidney stones in adults, especially for women, individuals of non-white race and non-overweight subjects. The increased risk may arise from caffeine from coffee.

Chethan, Sahadeb DeyAbstractThe present study was aimed to understand the development of bovine urolithiasis through measuring oxidative/nitrosative, cortisol and urokinase status and their relationship with disease severity. The cases of buffalo calves with obstructive urolithiasis were selected based on clinical signs, ultrasonography and laboratory examination of blood and urine (creatinine, urea nitrogen). Total 35 urolithiatic buffalo calves (urolithiatic controls) and 6 health...

In recent years, work has been done to understand the mechanisms of Doppler ultrasound twinkling artifacts (TAs) and why they appear over kidney stones. In the work described here, twinkling artifacts were evaluated as a possible method of locating and characterizing kidney stones. Doppler ultrasound scanning was used to evaluate 47 stones of different types and sizes in the range 1.31 –55.76 mm2 in cross-sectional area (average = 9.65 mm2). An isolated stone study was used to understand the behavior of the TAs.

AbstractExtracorporeal shock wave lithotripsy (SWL) is less invasive compared to the other invasive modalities of stone treatment that are gaining popularity. Hence, methods to improve the efficacy of SWL are desirable. We studied the effectiveness of dual frequency on the efficacy of stone fragmentation, but minimizing treatment time. A phantom 10  mm spherical BegoStone was fragmented in vitro in a kidney model using an electromagnetic lithotripter (Storz MODULITH®SLX-F2). A total of 78 stones were fragmented each with 3000 shocks at 60  Hz or 120 Hz or a dual frequency (DF) of 60–120 Hz. Fo...

AbstractBackgroundAlthough high-density lipoprotein (HDL) modulates many cell types in the cardiovascular system, little is known about HDL in the kidney. We assessed urinary excretion of apolipoprotein AI (apoAI), the main protein in HDL.MethodsWe enrolled 228 children with various kidney disorders and 40 controls. Urinary apoAI, albumin, and other markers of kidney damage were measured using ELISA, apoAI isoforms with Western blot, and renal biopsies stained for apoAI.ResultsPatients followed in nephrology clinic had elevated urinary apoAI vs. controls (median 0.074  μg/mg; interquartile range (IQR) 0.0160–...

Few medtech sectors are as hot as surgical robotics is right now, so it comes as no surprise that analysts tried to dig for information about Johnson &Johnson's plans for the market during the company's third-quarter earnings call Tuesday. "I couldn't be more bullish around how J&J is going to create value in this space," Ashley McEvoy, EVP and worldwide chairman of Johnson &Johnson's medical device segment, said during the call in response to an analyst's question about surgical robotics. "The goal that we're trying to achieve is really to make medical interventions smarter, less invasive, more pers...

This study assesses the feasibility and effectiveness of using a three-dimensional (3D) printing model for preoperative planning in the treatment of full staghorn stones, specifically in the selection of the most optimal calyx for puncture. Twelve patients were enrolled in this trial. A preoperative CT taken in prone position was performed on each of the patients. 3D models were reconstructed using digital imaging and 3D printers. Three identical models were printed for each patient. Three puncture sites from the upper-, middle-, and lower-pole calyces of the kidney models were selected for simulation of percutaneous nephr...
