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...

Radiation exposure – what is the optimal imaging modality in the follow-up of patients with urinary tract calculi?

Cumulative radiation dose is an important consideration in the nephrolithiasis patient population. Exposure to ionising radiation is known to be harmful and is associated with an increased risk of malignancy. Understanding radiation doses is necessary to make informed decisions regarding...

Supranormal function on MAG-3 – what is its significance and how to predict?

Differential renal function (DRF) on MAG-3 scans is typically used in patients with pelvic ureteric junction obstruction (PUJ obstruction). Supranormal DRF is when the kidney with PUJO has higher DRF than the normal contralateral kidney. The authors in this study...

Is outpatient robotic surgery feasible in children?

Minimally invasive surgery has helped to achieve shorter hospitalisations, reduce postoperative pain and analgesia requirements and provides better cosmetic results. Robotic urological outpatient surgery has been examined in recent times in the adult population; here Neheman et al. look at...

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
