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...

Radiological investigation of haematuria in 2016

This paper summarises the current evidence for and use of various imaging modalities for investigating haematuria. The following investigations are reviewed: Intravenous urogram (IVU) – the number of centres still using IVU is decreasing. IVU is cheaper and has less...

Tamsulosin and spontaneous passage of ureteral stones in children

This was a retrospective analysis of data for five years from four institutions comparing stone passage rates in children with ureteric stones ≤10mm, aged 2-18, treated with tamsulosin vs. analgesia alone. The study identified 449 children, of whom 334 were...

Prostatic artery embolisation – an option for select BPO patients

Few proponents of prostatic artery embolisation (PAE) regard it as a potential standard in future for benign prostatic obstruction (BPO) / benign prostatic hyperplasia (BPH) treatment. Present guidelines from the National Institute for Health & Care Excellence (NICE) and the...

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...

Stenting prior to URS or ESWL – does it increase ED visits and opiate prescriptions?

Ureteral stents are used to bypass obstructive stones, to dilate the ureter in order to facilitate ureteroscopy (URS), and to maintain patency / low intrarenal pressure following stone surgery. However, there can be morbidity (pain / voiding symptoms). Tasian et...

Intravesical instillation of chemotherapy before radical surgery for upper UTUC

Upper urinary tract urothelial carcinoma (UTUC) is a rare but increasingly prevalent form of urothelial cancer, accounting for 5–10% of cases, with an annual incidence of two to three cases per 100,000 individuals in Western Europe. Radical nephroureterectomy (RNU) with...

New charity launches to highlight urethral strictures – men’s silent epidemic

A new charity, the Collaboration for Urological Research and Education (CURE), has today called for urgent action to address one of Britain’s biggest silent epidemics – urethral strictures. Launching Stricture Awareness Month (SAM) in March, CURE has called on healthcare...

Localised renal cancer

Case 1 A 56-year-old lady is referred to the urology clinic after the GP conducted an ultrasound abdomen for deranged liver function tests and found a renal lesion. She is otherwise fit and well. Figure 1. What is the sensitivity...

Malignant upper urinary tract obstruction: emergency presentations and long-term outcomes

Malignant upper urinary tract obstruction (MUUTO) is a frequent emergency urological referral, often necessitating kidney drainage to preserve renal function. However, many patients have advanced cancer with limited life expectancy, raising questions about intervention benefits. While percutaneous nephrostomy (PCN) or...

Missed Meyer-Weigert duplex ureter during emergency ureteric stenting for ureteric stones

The Meyer-Weigert rule is a fundamental anatomical principle in urology that describes the typical orientation of ureteral orifices in duplex kidneys. In a duplex system, the upper pole ureter usually inserts inferomedially, while the lower pole ureter inserts superolaterally. This...

Demanding cases or nightmares in uro-oncology? May/Jun 2021

It’s not in the bag until it’s out of the abdomen: abdominal wall recurrence after ruptured retrieval bag during robot-assisted partial nephrectomy We present a case of failure of a specimen retrieval bag during a robot-assisted partial nephrectomy resulting in...
