Intravesical glycosaminoglycan analogue instillations for recurrent cystitis

Introduction The symptoms of recurrent cystitis can be triggered by inflammatory or infective causes. Bladder pain syndrome (BPS) and bacterial recurrent lower urinary tract infection can both present with symptoms of recurrent cystitis and cause significant morbidity in affected individuals....

Intravesical GAG replacement therapies for bladder pain syndrome / interstitial cystitis – an update

The barrier function of the glycosaminoglycan (GAG) layer of the urothelium was identified by Parsons in 1975, and intravesical therapies to treat chronic inflammatory conditions of the bladder were developed soon after. However, the active role of the urothelium in...

Technology – Part 3

Case 1 Figure A. Figure B. What is shown in figures A and B? What is the diameter of each scope? What is the working channel size of each? What are the advantages of a digital versus optic flexible ureteroscope?...

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...

Demanding cases or nightmares in uro-oncology? Sep/Oct 2022

Treatment of prostate cancer in renal transplant recipients is challenging due to a lack of knowledge of the natural history of cancer in these patients, the anatomical position of the graft in the iliac fossa and its proximity to the...

Infections and inflammation: Part 3

See also Part 1 and Part 2 Case 1 You review a man in the Emergency Department with scrotal pain and sepsis. His clinical examination findings are shown. What does this image show? Who was this condition named after? What...

Sacral agenesis and neurogenic bladder: long-term outcomes of bladder and kidney function

These authors looked at single institution outcomes for sacral agenesis (without spina bifida) with reference to renal function and bladder function. All had urodynamics either at diagnosis (56%) or soon after. Of 43 patients (23 female, 20 male), 37 had...

Stepwise voltage ramping causes less renal haematomas than fixed maximal voltage ESWL

Extracorporeal shock wave lithotripsy (ESWL) remains the recommended first line treatment for stones <2cm in the renal pelvis and upper or mid-pole calyces (Türk C, Knoll T, Petrik A, et al. European Association of Urology Guidelines on Urolithiasis. 2014). There...

Urinary NGAL, KIM-1 and L-FABP concentrations in antenatal hydronephrosis

he elusive search for being able to diagnose pelvi-ureteric junction obstruction (PUJO) continues and this group of researchers investigated the possible clinical application of urinary neutrophil gelatinase-associated lipocalin (uNGAL), urinary kidney injury molecule-1 (uKIM-1) and urinary liver-type fatty acid-binding proteins...

Near-infrared fluorescence in robotic surgery

This is a systematic review and critical analysis of the current evidence on the applications of near-infrared fluorescence (NIRF) in robotic urologic surgery. It uses indocyanine green (ICG), a sterile water-soluble dye which has been tested in various fields. In...

CRP to predict the need for surgical intervention in acute renal colic

A previous paper has suggested that C-reactive protein (CRP) is a useful serum marker for determining the likelihood of a patient with renal colic requiring surgical intervention, the cut-off level being >28mg/l (specificity 88.9%, sensitivity 75.8%). This prospective observational study...

Lower pole vessels in children with PUJO: laparoscopic vascular hitch or dismembered pyeloplasty?

A crossing vessel accompanying pelvi-ureteric junction obstruction (PUJO) occurs in 25-50% of cases. The Hellstrom vascular hitch procedure was first described in 1951 and has regained popularity since 2003 in the era of laparoscopic surgery as it negates the need...
