Detecting Kidney Stones Using Twinkling Artifacts: Survey of Kidney Stones with Varying Composition and Size

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.

Authors: Ali S, Sirota E, Ali H, Bezrukov E, Okhunov Z, Bukatov M, Letunovskiy A, Grygoriev N, Taratkin M, Vovdenko S, Afyouni A, Alyaev Y Abstract Objective: We sought to improve the educational and pre-operative training on various stages of percutaneous nephrolithotomy (PCNL) under fluoroscopic and ultrasound guidance. We developed a three-dimensional (3D) printed simulator (3D-printed PCNL model) for urological trainees.Methods: 40 s year urology residents were randomly assigned into two groups, completing PCNL surgical steps on a URO Mentor™ surgical simulator (Group A) or on our new 3D-printed PC...

When most people think about E coli, the first thing that comes to mind likely is eating tainted food or as a result of improper handwashing. What came as a surprise to me was that it can also show up as a UTI (Urinary Tract Infection) caused by kidney stones that back up in the urethra, which prohibits the flow of urine. It is more than an academic exercise that had me researching this all too common condition in men and women. As I am writing, I am less than 24 hours post-surgery to remove these pesky critters that have been backing up the works since 2014. It was my fourth go around that culminated in a cystoscopy,...

Abstract Point-of-care ultrasonography (POCUS) is performed by a physician at the bedside and is standard practice in obstetric, emergency, and musculoskeletal medicine. When compared with formal sonography, POCUS is equivalent in screening for abdominal aortic aneurysm and as accurate in diagnosing deep venous thrombosis. POCUS has high accuracy for diagnosing pneumonia and detecting acute decompensated heart failure but is less accurate than computed tomography for identifying pulmonary embolism. POCUS confirmation of intrauterine pregnancy rules out an ectopic pregnancy. In the third trimester of high-risk preg...

Conclusion: The 3D-guided approach to PNL facilitates the preoperative planning of the puncture with better knowledge of the renal anatomy and may be helpful to reduce operative time and improve the learning curve.

CONCLUSIONS: The incidence of de novo nephrolithiasis in ESRD patients on HD was 10.5%. Increased serum uric acid, decreased serum magnesium and ionized calcium, and absence of hypertension were associated with increased stone-formation in ESRD patients on HD.

ConclusionsGiant parathyroid adenoma is a rare cause of primary hyperparathyroidism and usually presents symptomatically  with high calcium and parathyroid hormone levels. Giant parathyroid adenoma is diagnosed by imaging and laboratory studies. Management is typically surgical, aiming at complete resection. Patients usually recover with no long-term complications or recurrence.

Abstract Renal colic is a common complaint that presents to the emergency department. It is estimated that 13% of men and 7% of women will develop a renal stone. There is a high probability of recurrence, with 50% within 5 years. Computed tomographic scan of the abdomen and pelvis without contrast and the ultrasound of the kidneys, ureters, and bladder are the common diagnostic imaging modalities used for diagnosis. Initial treatment includes analgesics and medical expulsive therapy. Most of the patients will pass their stone spontaneously within 3 days. The remaining 20% will require urologic interventi...

ConclusionPrimary hyperparathyroidism continues to be mainly a symptomatic disease in the Kashmir Valley. There is a decreasing trend of symptomatic cases and an increasing number of asymptomatic cases with time. The level of 25(OH)D has no correlation with serum calcium, iPTH or tumor size in these patients.
