Urinary retention in the females is not uncommon, but the results of management have usually not been satisfactory. In the past 7 years, 47 female patients with recurrent urinary retention (mean age: 65.4 years old) have been seen here. The underlying diseases of these female patients were post-operative complications, spine compression fracture, cervical cancer, cerebral vascular accident, diabetes mellitus and psychiatric diseases. Complete history taking, physical examinations (especially neurological examinations), initial catheterizing volume, and urodynamic studies were performed for evaluation of bladder function. The patients were further classified as Group A: normal detrusor contraction in cystometrogram(CMG) with simultaneous relaxation of electromyaogram(EMG); Group B: normal detrusor function in CMG with no relaxation or increased activity in EMG; Group C: no active detrusor contraction detected in CMG with good compliance: Group D: poor compliant bladder with no active detrusor function. The primary management of recurrent urinary retention is modifed intermittent catheterization program(ICP): three times to four times a day and Foely catheterization in the night. Normal voiding is defined as spontaneous voiding with residual urine less than 100 ml in two consecutive examinations. All the Group A patients could void normally; 50% of Group B patients and 57% of Group C patients could void normally after the above management. However, none of Group D patients could void normally in spite of ICP training. Initial catheterization volume was an important factor in predicting the time necessary for ICP training. For patients with no evident neurologic deficit, the mean time of ICP training was 5.4 days for initial retention volume less than 600 ml; and 13.5 days for a volume greater than 600 ml. Most(70%) of the female urinary retention could be managed simply by ICP training. Urodynamic study is helpful in predicting the results of training. Alpha-adrenergic blockers were used to prevent post-operative urinary retention according to many reports, but the awareness of physicians and nurses to signs of urinary retention may be even more important in the prevention and early treatment of female urinary retention.
