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...

The microbial syndicate: dysbiosis and origins of recurrent UTIs

Traditional dogma held that urine was sterile. However, recent molecular studies have revealed an underground microbial community, known as the urinary microbiome or ‘urobiome’ [1]. Far from being harmful, this community of microorganisms helps modulate immune responses, regulate inflammation, and...

A new haemostatic agent in tubeless PCNL

Tubeless percutaneous nephrolithotomy (PCNL) is increasingly being used in carefully selected patients to reduce hospital stay and analgesia requirements, especially in those with little bleeding who become stone free or have insignificant residual fragments (usually <4mm). Various agents have been...

Percutaneous nephrolithotomy: wisdom, dogma, paradigm and myths

A non-transpapillary technique appears to ease access to the kidney – the most critical step in percutaneous nephrolithotomy (PNL) – when compared to the classic transpapillary approach. Remarkably, the earliest descriptions of percutaneous access by Goodwin et al. in 1955...

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...

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...

Imaging and Intervention in Urinary Tract Infections and Urosepsis

Urinary tract infections (UTIs) are highly prevalent in the community and account for approximately 40% of hospital-acquired infections. Yet, they are often underestimated and under-diagnosed: as one chapter of this book is entitled, nothing is simple about acute pyelonephritis. This...

Radiology quiz

We are delighted to introduce something new for the Uroradiology Focus – our very own Jane Belfield has put together a urology imaging quiz with 10 cases designed to grab your interest and test your knowledge. Good luck and let...

ESWL, fURS and PCNL for lower pole renal stones

Lower pole stones (LPSs) are common but less likely to pass spontaneously than other renal stones, often necessitating intervention. In 2015, a systematic review and meta-analysis comparing percutaneous nephrolithotomy (PCNL), flexible ureterorenoscopy (fURS), and extracorporeal shockwave lithotripsy (ESWL) was published....

FANS f-URS with mPCNL for 2–3cm renal stones

Flexible ureteroscopy (f-URS) has undergone substantial evolution with the introduction of flexible and navigable suction ureteral access sheaths (FANS), expanding its applicability to larger renal calculi. Although mini-percutaneous nephrolithotomy (mPCNL) remains a standard treatment for 2–3 cm renal stones, uncertainty...

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...

Testicular tumour imaging

Testicular tumours are the most common tumour in young males with a peak incidence seen between 25 and 34 years [1]. The overall incidence is slowly increasing, although the exact reasons for this are uncertain, and there is a greater...
