Female stress and urge incontinence in family practice: insight into the lower urinary tract.

As many as 25% of all women are affected by urinary incontinence, but only a few are treated. This frequent, often medically unrecognised, condition occurs in women of all ages. The continence mechanism is based on bladder detrusor control, intact anatomical structures in and around the urethra, correct positioning of the bladder neck and a comprehensive innervation of the lower urinary tract. Age and childbearing are established risk factors for the development of urinary incontinence, but other factors are currently suggested. The evaluation of urinary incontinence should include history, gynaecological examination, urine test, frequency-volume diary and a pad-weighing test. Female urinary incontinence can be treated in general practice by simple means, e.g. pelvic floor muscle training, bladder training, electrostimulation, drug therapy, or a combination of these approaches. This review updates the knowledge of the continence mechanism and summarises the epidemiology, risk factors, assessment and treatment of urinary incontinence in general practice.
