- 1. UDS ASSISTANT A Software for Urodynamic Semi-Automated
Diagnosis
2. Why a Software ?
- In recent years the role of urodynamics in the assessment of
lower urinary tract dysfunctions has become contentious
- Often the literature is contradictory and lacks adequate
evidence, rendering meaningful conclusions difficult
- In an attempt to overcome these shortcomings the International
Continence Society (ICS) has published a number of standardization
reports to guide clinical and research activity .
3. ECG Automated Diagnosis
- Electrical spikes & segments
- Pressure spikes & segments
4. Algorithms Sources-I
- An international urogynecological association
(IUGA)/international continence society (ICS) joint report on the
terminology for female pelvic floor dysfunction
5. Algorithms Sources -II 6. Display 7. Single vs multichannel

Algorithms Rationale 12. Flowmetry Analysis Siroky - male < 50
yrs Bristol - male > 50 yrs Liverpool - female 13. Male Free
Flow Predictive Value
- Unobstructed Qmax >15ml/s
- ( Warning: 50% may be obstructed High Pressure / High
Flow)
- Equivocal Qmax10 to15 ml/s
- ( Warning:70% may be obstructed ; 30% may be unobstructed
DU
- Obstructed Qmax 200ml check upper tract for dilation
16. Filling Phase (Cystometry) Analysis
- ( clinically< 15 cm H20 significant contractions)
- ( early sensation < 100mlwhithout contractions )
- ( > 10 cmH20 at cystometric capacity)
17. PRESSURE/ FLOW ANALYSIS-Male ICS Nomograms
- between 60 and 90 cm H20Equivocal
- 50 yrs 63. LiverpoolNomogram Female 64. Male Free Flowmetry
Predictive Value
- Should all patients with LUTShave pressure-flow studies?

- The purposeof the software is just to give some skill in
interpreting the findings
- The software doesnt substitute in any way the clinical
experience
- To get the best from a urodynamic investigation, it is
necessary to understand the patients complaint and distinguish
clinically significant findings from equipment malfunction.
- The software may ensure consistency between all who carry out
urodynamics
- Once validated , it may be an instrument for the assessment of
clinical reliabilty ofcurrent urodynamic tests
78. Future Software Developments
79. Urodynamics in Pediatric Age
- Flowmetry( Liverpool Nomogram )
- Bladder Capacity ( Age x 30 + 30)
- 6 years old boy : 6x30+30 = 210 ml
