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...

ESWL and URS for treatment of paediatric urolithiasis

Tejwani et al. have undertaken a comparative effectiveness study to characterise differences in procedure frequency, postoperative re-admissions and emergency room (ER) visits, and repeat treatment rates for children (≤18 years) with urolithiasis who underwent initial intervention with extracorporeal shock wave...

Medical expulsive therapy for paediatric urolithiasis

Children who have kidney stones are likely to have recurrences. Many initial stones are treated conservatively allowing for spontaneous passage of small stones if possible. Doxazocin or tamsulosin are known to dilate the ureter and allow spontaneous passage of stones...

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...

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...

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...

Testicular microlithiasis

Introduction Testicular microlithiasis (TML) was originally described in 1970 in a healthy four-year-old boy [1] and the first paper regarding microlithiasis as an entity seen on ultrasound was published in 1987 [2]. Testicular microlithiasis is seen on ultrasound as small,...

An update on lower pole stone management for 2015

Introduction Urolithiasis is an increasing healthcare problem, with an estimated lifetime prevalence of up to 15% [1]. The number of interventions undertaken for stone disease has increased dramatically over recent years, particularly with respect to ureteroscopy and percutaneous nephrolithotomy (PCNL)...

The role of continuous prophylactic antibiotics following JJ stent insertion

Urinary tract infections (UTI) and stent-related symptoms (SRS) are frequently recognised complications of ureteric stent placement. Antibiotic administration at induction prior to ureteric stent insertion is recommended by the European Association of Urology (EAU). Commencing prophylactic antibiotics for the ‘entire...

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...

Tackling stones in children: is it difficult to crack on?

The incidence of stone disease in the paediatric population has been increasing worldwide, particularly for the adolescent age group (12–17 years of age). In this article the authors discussed the evolutions of percutaneous nephrolithotomy (PCNL) and ureteroscopy (URS) in children....

Testicular cancer (Jan 2016)

Case 1 A 26-year-old male presented with a two-week history of testicular pain and swelling. On examination the right testicle was enlarged, indurated and tender. Erythema of the scrotum on that side was also noted. Ultrasound of the testis reported...
