Implementation of a clinical practice guideline for assessment and management of renal colic in the emergency department.

Introduction: Renal colic is a common emergency department (ED) presentation. Variations in assessment and management of suspected renal colic may have significant implications on patient and hospital outcomes. We developed a clinical practice guideline to standardize the assessment and management of renal colic in the ED.

Is Size All That Matters? New Predictors of Complications and Bleeding in Renal Angiomyolipoma.

Purpose: Renal angiomyolipoma (AML) is the most common benign renal tumor. Whilst generally asymptomatic, they can cause life-threatening bleeding. Selective angioembolization (SAE) may be used to treat large symptomatic and asymptomatic AMLs.

Anatrophic nephrolithotomy and pyelolithotomy for dual staghorn calculi in bifid collecting system.

A bifid ureter is an atypical anatomical variation that occurs with an incidence of 1-10%. This anomaly is in a continuum of duplex collecting systems and most commonly involves a common distal ureter. This is usually asymptomatic and is predominantly an incidental diagnosis, nevertheless, is a potential risk factor for urolithiasis formation.

A prospective multicentre phase III validation study of AZGP1 as a biomarker in localized prostate cancer.

Background: Prostate cancers (PCs) with similar characteristics at the time of diagnosis can have very different disease outcomes. Conventional biomarkers of PC still lack precision in identifying individuals at high risk of PC recurrence. While many candidate biomarkers are proposed in the literature, few are in clinical practice as they lack rigorous validation.

Papillary Renal Cell Carcinoma Seeding along a Percutaneous Biopsy Tract.

We report a case of tumour seeding caused by percutaneous biopsy of a papillary renal cell carcinoma detected on pathological assessment of the partial nephrectomy specimen in a 50-year-old male. Whilst percutaneous biopsy of renal masses is considered to be safe and can be a valuable tool in the assessment of certain renal lesions, it is not without risks. This rare complication should be taken into consideration before contemplating its use in a patient.
