Psychiatric issues in the "loin pain and haematuria syndrome".

The Loin Pain and Haematuria Syndrome is a relatively new diagnosis applied to the problem of persistent loin pain, often with haematuria, in the absence of identifiable explanatory organic pathology. Case reports have suggested a range of salient psychopathological features associated with the complaints of pain and haematuria, although the psychological factors have been largely neglected in understanding the aetiology or in approaches to management. The roles of illness behaviour, patterns of somatisation, and psychiatric disorder associated with chronic pain syndromes, need to be addressed, as do the patterns of medical and surgical response to these patients. The use of the term "syndrome" to describe these symptoms implies a degree of uniformity in clinical features and outcome that has not yet been substantiated. New surgical techniques have been developed such as renal denervation and renal auto-transplantation to treat the pain, with limited success. A review of this condition illustrates the frequent failure of medicine to apply multi-factorial biopsychosocial models to understanding the aetiology and management of unexplained physical symptoms. It also illustrates the failure of our current nosology and understanding of somatoform disorders to achieve application outside psychiatry.
