Pref ace   
 We have written this clinical companion for medical students and junior doc-
tors who have told us over the years that renal medicine is ‘too diffi cult’ and 
not always well covered in textbooks. We suspect this may be a consequence 
of a tendency to concentrate on mechanisms as a prerequisite for understand-
ing disease and we have made a conscious decision to avoid this approach. 
Renal physiology and pathophysiology are undoubtedly interesting but they 
are also complex and a  detailed  knowledge of what happens inside the renal 
tubule is probably not necessary to assess, investigate and manage a patient 
with acute kidney injury or chronic kidney disease. 
 We have also made a conscious decision to divide the text into bite size 
chunks using a Q and A format. We have done this partly because we have 
found this approach works when teaching and partly because there is so much 
more to learn than there was 20–30 years ago. With this approach in mind we 
have divided our material into six sections. We start with the physiology that 
it helps to know and go on to assess GFR, proteinuria and haematuria. We 
include a section on electrolyte and acid-base disorders next as nephrologists 
are frequently asked for help in these areas. We devote considerable space to 
AKI and CKD because these topics are most likely to be encountered by 
general medical trainees. We then describe a miscellaneous group of renal 
topics including urinary tract infection and renal stones before tackling renal 
replacement therapy in a way that we hope will make clearer to non- 
nephrologists exactly what goes on inside dialysis and transplant units. We 
conclude with a series of appendices. We have always taught students that 
there are some things they need to know and some things they need to look 
up. The appendices are where medical students and junior doctors will fi nd 
material they don’t always need to carry in their heads. 
 We are grateful to a number of colleagues who have reviewed chapters for 
us, helped with illustrations or provided us with slides. In particular we would 
like to thank Alison Almond, Zeyad Bayaty, Lynn Carson, Louise Clark, 
Fiona Gardiner, Fiona Green, David Kipgen, Thalakunte Muniraju, Calum 
Murray, Sue Robertson, Subrata Saha, Ranjit Thomas, Abdul Wahab and 
Wayne Wrathall. We also acknowledge many other colleagues, especially 
John Firth and Roger Greenwood, whose lectures have stimulated us to

 consider different ways of approaching and teaching a  particular topic. Last 
but by no means least we thank our wives, Maytal and Karen, for their toler-
ance and patience during the many evenings we spent drafting and redrafting 
this book.
