A cross sectional study to assess the need of urodynamic studies in lower urinary tract patients attending an urogynaecology clinic

Background Urodynamic studies are gold standard to objectively diagnose lower urinary tract symptoms and dysfunction Aims and

Objectives To correlate clinical symptoms of lower urinary tract with urodynamic study to know whether urodynamics is really required routinely in patients with lower urinary tract symptoms (LUTS).

Methods The study was conducted at Century hospital Hyderabad and Dr Lalitha’s urogynaecology clinic Hyderabad, India during 15 days; from 2 September 2015 till 16 September 2015 with 48 patients. All cases coming to urogynaecology clinic who were taken up for urodynamic study were included. Statistical analysis was done by  student’s t test with p<0.05 considered statistically significant.

Results Total patients with urinary frequency were 13 out of which 7 (53.84%) had cystometric capacity of less than 200ml. Out of 16 patients with urgency and urge incontinence 10 (62.50%) had high detrussor pressure during voiding. 50% patients had max cystometric capacity <200ml. Out of 7 patients with SUI (stress urinary incontinence) only one had genuine stress incontinence; all oth-ers had mixed incontinence with either raised EMG or raised Pdet. Out of 15 patients with com-plaints of voiding dysfunction 14 (93.33%) had low flow rate that is Qmax <15ml/sec. Out of 15 patients 2 had features of DSD (detrussor sphincter dyssynergia). Total 6 patients had raised EMG as cause for difficult voiding.

Conclusions Detrusor sphincter dyssynergia as a cause of dysfunctional voiding is diagnosed using urodynamic study with EMG. Urodynamic study is important and useful tool to evaluate female lower urinary tract symptoms and unnecessary delay in doing a detailed urodynamics should be avoided.
