Loin pain haematuria syndrome
Loin pain haematuria syndrome is an uncommon but disabling condition which presents with recurrent severe loin pain and either microscopic or macroscopic haematuria. It predominantly affects young Caucasian females. The aetiology is unclear, but it seems to be most commonly initiated by glomerular bleeding. There are no defining features of the disorder on any investigation, and it is mostly termed a diagnosis of exclusion. A lack of a clear definition of the condition and uncertainty about the aetiology mean that this is still a poorly understood entity. A variety of medical and surgical treatments have been used with mixed results. The mainstays of treatment are effective analgesia management and involvement of a multidisciplinary team including psychological support.
