Secondary bladder cancer following upper tract urothelial cancer
Upper tract urothelial carcinoma (UTUC) comprises <5% of all urothelial cancers. A certain proportion of patients with UTUC will develop secondary bladder urothelial cancer (BUC). This paper has retrospectively examined records obtained from several cancer USA population-based registries of more...
Predicting bone scan positivity in non-metastatic CRPC
There is evidence that suggests that early treatment with chemotherapy, immunotherapy or hormone therapy leads to a better response in patients with asymptomatic metastatic castrate resistant prostate cancer (CRPC). This study aimed to predict bone scan positivity in patients with...
Rectal swab testing before prostate biopsy
This study explored the real terms value of rectal swab testing and targeted antibiotic prophylaxis in patients undergoing transrectal ultrasound prostate biopsy in view of increasing bacterial resistance to fluoroquinolones (17.6% in North America, 40% in Hong Kong). The authors...
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...Seminal vesicle calculi

Does stable or decreasing hydronephrosis on ultrasound lead to stable or improved function on diuretic renography?
Antenatal hydronephrosis is noted in approximately 1% of all pregnancies. Persistent renal obstruction may lead to progressive loss of renal function. Renal ultrasound (USS) is the preferred modality for diagnosis and monitoring of paediatric hydronephrosis as it is non-invasive, non-ionising,...
