Kidney biopsy

A biopsy is a small sample of tissue taken from any area of the body so it can be examined under a microscope. A sample of kidney tissue may be taken using an endoscope (a thin, flexible tube with a bright light and camera). This page from Great Ormond Street Hospital (GOSH) explains the kidney biopsy procedure and what to expect when your child comes to GOSH to have one. 

Bronchoscopy, bronchogram and optical coherence tomography studies

This page from Great Ormond Street Hospital (GOSH) explains about bronchoscopy and bronchogram (B&B) studies and also the optical coherence tomography (OCT) study, which can be carried out during the same procedure. It explains why these may be suggested and what to expect. This combination of tests is carried out in the Interventional Radiology department. 


A splenectomy is an operation to remove the spleen. It can be carried out using keyhole surgery or traditional open surgery. Most splenectomies at GOSH are carried out using keyhole surgery.
