In absence of standardised criteria diagnosis of lower urinary tract dysfunction is difficult in women. Comprehensive urodynamics including pressure-flow study, urethral pressure profilometry, EMG as well as video coordination (or separately done MCUG) are often required. pelvic floor dysfunction (so called dysfunctional voiding), bladder neck obstruction and urethral stricture are differential diagnoses. initial treatment of dysfunctional voiding includes behavioural modification, pelvic floor relaxation exercises, medications, treatment of constipation. further treatment includes inj Botox into sphincter and sacral neuromodulation.
