Brief summary

Kidney biopsy is an important test to diagnose and monitor many kidney conditions. It is performed with ultrasound to allow continuous vision of the biopsy needle passing into the kidney. This requires the operator to hold the ultrasound probe with one hand whilst manipulating the biopsy needle with the other, which can be difficult for newcomers. A needle guide attached to the ultrasound probe ensures the needle and ultrasound probe are always aligned to provide optimal images of both the kidney and needle simultaneously. Junior doctors will be randomly assigned to perform an ultrasound guided kidney biopsy in a synthetic model, with or without the aid of a needle guide. The impact of the needle guides will be assessed according to safety and adequacy as well as user feedback, to determine which method is superior for teaching this skill to junior doctors.

Interventions

This trial is designed to compare the two methods of performing renal biopsy - either using an ultrasound probe needle guide or freehand - for the teaching of junior doctors. The intervention will be the use of the ultrasound probe needle guide. This will be performed on a simulation mannequin. The training to use the ultrasound probe needle guide will be in the form of a single 15 minute presentation including video demonstration. This demonstration will undertaken by a renal physician experien
