Understanding gender differences in nephrolithiasis

Rates of nephrolithiasis are higher in males than females. The cause for this remains unclear, however animal models have demonstrated an association between sex steroid hormone levels and lithogenesis. This relationship in humans is less well established. This study from...

Outcome analysis of paediatric pyeloplasty

This prospective study from India included 744 patients of whom 112 had renal function less than or equal to 20% at the time of diagnosis. Thirty percent underwent a nephrostomy initially. Ten with no function had a nephrectomy. Of the...

Effect of collimation on radiation dose during ureteroscopy

Over 60,000 ureteroscopies are performed annually in the UK. During these procedures radiation is used and there are concerns regarding the cumulative dose during a surgeon’s career. Common ways to minimise the dose to the theatre team are wearing lead...

Do adult men with untreated ventral penile curvature have adverse outcomes?

The history of ventral penile curvature if untreated in childhood is not known. The authors tried to assess this by performing an online survey of adults who had untreated ventral penile curvature using a Facebook advertised survey. Their outcome measures...

Glans size is an independent risk factor for urethroplasty complications after hypospadias repair

In this analysis, prepubertal patients undergoing hypospadias repair over a four-year period had caliper measurement of glans width taken perioperatively. Multivariate logistic regression analysis was carried out for complications while adjusting for patient age, meatus position or type of repair....

Liquid paraffin versus lidocaine

Topical anaesthetics have been used in urology since 1884, when Pease described using “cocaine in a sensitive urethra with charming results”. Since 1949, 2% lidocaine has been increasingly used intraurethrally for cystoscopy and other procedures. This article is a pilot...

Accuracy of orchidometry in boys with varicocele

The management of adolescent varicocele remains controversial. One issue that remains unresolved is that of testicular size determination pre and post any form of conservative or surgical option. These authors compared the results of using a Rochester orchiometer and ultrasound...

A new treatment algorithm for ureteral fibroepithelial polyps in children

Fibroepithelial polyps are rare in the urinary tract (found in 0.5% of all paediatric pyeloplasties and 5% of all cases of paediatric ureteral obstruction). The advent of ureteroscopy in paediatrics has increased the identification and treatment of these. This paper...

Bladder cancer outcomes in patients with spina bifida

These authors carried out a systematic review using PubMed and a number of terms to pick up studies with an underlying diagnosis of myelomeningocele and bladder cancer, with exclusions of cord injury, tuberculosis, schistosomiasis, or prior ureterosigmoidostomy. Their aim was...

Hypospadias surgery complication rates

These authors identified all children undergoing NHS hypospadias surgery between 1999 and 2009 in England using the hospital episode statistic database and looked at repair types and complications. High-volume centres (24/75) were classified as such if they did more than...

Non-antibiotic options for recurrent UTI

Recurrent urinary tract infection (UTI) imposes a heavy burden on health services. By definition recurrent UTI is two infections in six months or three in one year. The annual incidence of single UTI is 30 per 1000 women. The Scottish...

Cystolithotripsy using the holmium laser: evolving uses for the laser lithotrite

This small prospective study examined 20 patients who were undergoing laser cystolithotripsy for bladder stones. Laser lithotripsy was performed using either a 365 or 550µm holmium:YAG laser fibre with a power setting of 1.0J and a frequency of 10Hz. Stone...
