Fowler's syndrome (urethral sphincter relaxation disorder) is a disease characterized by urinary retention with abnormal electromyographic activity in young women [1].[2][3]
Presentation
Urinary retention is a relatively uncommon presentation in young women. Fowler's syndrome primarily presents in women under the age of 30 years. It is seen in about one third of women having complaints of urinary retention. The predominant complaint is the inability to urinate for a day or more with no urgency to urinate, in spite of a large bladder volume of more than 1 liters. Normally a person feels the need to urinate at a bladder volume of 400-500ml. The person usually has a progressively increasing lower abdominal pain. The condition can be associated with Polycystic ovary Syndrome and Endometriosis.
Alternatively, women with Fowler's Syndrome can present with impaired voiding, voiding difficulties with or without incomplete bladder emptying, may have increased urinary frequency and occasionally impairment in urination and increased frequency of urination, but rarely become incontinent.
Women with Fowler's Syndrome often find catheterisation extremely painful. [4] [5]
Cause
The exact cause of Fowler's syndrome is not yet known. A possible cause is an abnormality in muscle membrane, possibly due to a hormonally dependent channelopathy.[6] This may cause an excessive excitability of the external urethral sphincter which prevents the adequate relaxation of the muscle necessary for voiding .[7]
Diagnosis.
Women with Fowler's syndrome are often found to have an abnormally elevated urethral pressure profile, increased urethral sphincter volume and characteristically abnormal electromyography of the urethral sphincter [8]
Cystometrogram shows large bladder capacity and absence of sensations during the filling phase. The maximum urethral closure pressure (MUCP) is raised.[9] The diagnosis is done by testing the electromyographic (EMG) activity of external striated urethral sphincter. The usual findings are complex repetitive discharges without and with deceleration (decelerating bursts), suggesting an impairment in sphincter muscle relaxation.[10][6]
Treatment
Sacral neuro modulation is the commonly practiced treatment for restoration of normal micturition. This technique involves modulation of micturition reflex by stimulating S3 nerve root.[11][12]
History
This disease was described first by Fowler et al in 1985.[13]
