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...

A guide to percutaneous nephrolithotomy

Percutaneous nephrolithotomy (PCNL) is now the gold standard approach to treating large renal stones. Since its development in the 1970s, it has undergone a series of refinements that could only have been possible with the symbiosis of both radiological and...

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...

Smith’s Textbook of Endourology (3rd Edition)

Without doubt this represents the endourological bible for the urological fraternity and unquestionably reflects a labour of love for its authors. At approximately 1900 pages it is no pocket book of modern urology, and whilst clearly encyclopaedic in its content,...

EMS Flexible Ureteroscopy and Percutaneous Surgery Masterclass

The Masterclass comprises a combination of didactic presentations, as-live surgery presentations, and live case observation on surgical techniques, tips and tricks, and the medical management of stone patients.

Use of bone windows in urological CT

Introduction Unenhanced computed tomography of kidneys, ureter and bladder (CTKUB) is the recommended gold standard investigation in patients with acute renal colic. CT urography is now a commonly used technique in the investigation of haematuria, for surgical planning and for...

Demanding cases or nightmares in endourology? May/Jun 2016

In the third article in this series the authors describe their experience with the very rare indications for laparoscopic stone surgery. Case 1 A 44-year-old woman presented with several months of malaise and right flank pain. A CT scan demonstrated...

Why defining and managing DUST matters in endourology

In endourology, defining ‘DUST’ and optimising its management is vital for improving stone-free rates (SFR) and reducing complications. Residual fragments, even those ≤4mm, can act as a nidus for infection, obstruction, and recurrence. Studies have shown that 30% of patients...

Cutting on the Staff

In this series of articles I am going to show you some of the exhibits contained in the BAUS Virtual Museum of the History of Urology which is part of the BAUS website (www.baus.org.uk). In the last article I described...

Factors associated with post ureteroscopy urosepsis

The authors investigate which factors were most likely to increase the risk of postoperative urosepsis within 28 days of ureteroscopy (URS) and laser stone fragmentation by analysing the 34 of 562 patients who developed this complication. Stone size, same session...

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...

Kidney stones in pregnancy
