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...

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...

The management of renal calculi – Pt 1

Renal calculi can be managed according to four treatment options: conservative management, extracorporeal shockwave lithotripsy (ESWL), flexible ureterorenoscopy (FURS) and percutaneous nephrolithotomy (PCNL). This is the first in a two-part series in Urology News (Part 2 available here) that will...

The management of renal calculi – Pt 2

Renal calculi can be managed according to four treatment options: conservative management, extracorporeal shock wave lithotripsy (ESWL), flexible ureterorenoscopy (FURS) and percutaneous nephrolithotomy (PCNL). Having addressed conservative management and ESWL in the last edition of Urology News, the second article...

A negative ureteroscopy for stone disease: is it acceptable and is it avoidable?

Urinary tract stone disease and the consequent demand for endoscopic intervention in the upper urinary tract is an increasing phenomenon [1]. Although ureteroscopy is generally considered to be associated with low morbidity [2], risks do exist. Recognised complications include urothelial...

Seminal vesicle calculi

Epidemiology Seminal vesicle calculi are uncommon with just over 100 cases being reported in the literature, although the true incidence is likely to be higher [1-9]. Patients usually present aged between 30 and 45 years old and although the pathogenesis...

Does more equal less in the management of acute renal colic?

Radiographs of kidneys, ureter and bladder (KUB) have long been used in the follow-up of patients with ureteral stones to reassess stone position and surgical planning. Emergence of computed tomography (CT) as the gold standard for the diagnosis of ureteral...

The role of conservative renal colic treatment

Acute renal colic is a common emergency condition, which can arise from a variety of underlying conditions that affect the urinary tract, but it is usually associated with the passage of ureteral stones. Before considering expectant management or active intervention,...

Risk stratified approach to early intervention for renal colic

Existing guidance on this topic is based on older and smaller studies, and there remains variation in practice. This review of database outcomes of 1168 out of 3081 (38%) patients who underwent early intervention after presentation to nine Canadian emergency...

Preoperative stenting compared to non‑stenting in ureteroscopy for urinary stone disease

Urolithiasis, one of the most prevalent urological conditions worldwide, significantly affects patients’ quality of life. In the United States, its lifetime prevalence is approximately 1 in 11, while global rates vary from 1% to 13%. The management of urolithiasis offers...

Time for tea

Kidney stone disease can be related to genetic, biochemical, and dietary factors. Much has been said about the link between tea and coffee consumption and risks of urinary stone formation. This is a systematic review using the PRISM statement with...

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...
