A combined urodynamic and continence unit--a review of the first 19 years

We have completed a 19-year audit of all patients referred to the urodynamic/continence unit since its inception in 1972 and their subsequent clinical management; a total of 20,437 patients were referred, increasing from 51 in the first year to 1564 in 1990. Although the annual number of referrals has remained constant for the last 8 years, the need for more complex urodynamic assessment such as video-cystourethrography has increased from 5% (56/1164) in 1981 to 25% (385/1564) in 1990. The number of out-patient attendances to medical, physiotherapy and continence clinics has also increased over that period. We conclude that the number of referrals represents increasing recognition of the value of urodynamic assessment. Accurate diagnosis leads to more effective treatment, whether surgical, medical or conservative. Some methods of diagnosis are complex and suitable only for a tertiary referral centre.
