Nephrocalcinosis
Case 1 What does this x-ray of the kidney, ureter and bladder (KUB) show? What are the likely causes? What is the pathology behind medullary sponge kidneys (MSK)? What is the risk of urolithiasis with MSK? How are such patients...
Pain relief after removal of non-obstructive renal calculi
Non-obstructing stones are often not considered to be the source of pain, and probably most are not. This is because flank pain associated with a stone is typically caused by a stone that obstructs urinary flow, which increases intraluminal pressure...Urolithiasis – metabolic considerations
Case 1 A 32-year-old female patient is diagnosed with a ureteric calculus for the first-time. What type of metabolic evaluation investigations should be performed? When should stone analysis be repeated? What are the most common metabolic abnormalities associated with calcium...
Understanding gender differences in nephrolithiasis
Rates of nephrolithiasis are higher in males than females. The cause for this remains unclear, however animal models have demonstrated an association between sex steroid hormone levels and lithogenesis. This relationship in humans is less well established. This study from...Why bother? Metabolic screening for stone formers
Introduction Despite the considerable increase in the incidence of stone disease in the UK and elsewhere in recent years, urologists have engaged with preventative strategies to only a limited degree. With mounting evidence of the strong correlation between obesity and...Metabolic screening and stone-prevention in urolithiasis patients
The incidence and prevalence of kidney stones is increasing [1,2]. Significant recurrence rates are noted with 14% of patients experiencing a further episode at one year, 35% at five years, and 52% at 10 years [3]. Over 10% of stone...Kidney stones in pregnancy
Case 1 A 28-year-old female, 19 weeks pregnant, presents with severe left loin pain. There is no past medical history of note. Blood tests show a white cell count of 14.1x109/L and creatinine of 56umol/L. An ultrasound scan (USS) reports...Dietary citrate substitution in urolithiasis patients
Stone formation is dependent on supersaturation of urinary salts and urinary crystal retention. Urinary promoters (protein aggregates, cell debris) and inhibitors (citrate, magnesium, urinary macromolecules such as glycosaminoglycans and proteins) are involved in the process of stone formation [1]. Hypocitraturia...
Radiation exposure – what is the optimal imaging modality in the follow-up of patients with urinary tract calculi?
Cumulative radiation dose is an important consideration in the nephrolithiasis patient population. Exposure to ionising radiation is known to be harmful and is associated with an increased risk of malignancy. Understanding radiation doses is necessary to make informed decisions regarding...Increasing patient hydration through technology
Achieving optimal hydration is crucial particularly for patients with nephrolithiasis. Research suggests that intake should approach 2.5–3.5 litres per day to allow for the daily excretion of 2–3 litres of dilute urine [1]. Unfortunately, patient compliance is known to be...
