method of standardization and optimization of the parameters at bladder distension Attempts to improve therapeutic efficacyin IC/BPS
Useful signs anf criteria in diagnostics of IC/BPS • Pelvic pain and dyscomfort • Frequent urination • Urge symptoms • Negative urine test • Exclusion of UTI • Presence of symptoms >3 months • Characteristic view at cystoscopy (in 70%) • Exclusion of all other bladder illnesses
Currentmethod of hydrodistension • Pelvic pain and dyscomfort • Frequent urination • Urge symptoms • Negative urine test • Exclusion of UTI • Presence of symptoms >3 months • Characteristic view at cystoscopy (in 70%) • Exclusion of all other bladder illnesses
Most important diagnostictool:HighPressureCystoscopy • Extension of visiblemucosaglomerulationsdependson: • level of intravesical pressure • time of dilation. • Standardization and optimization of theseparameters is urgentlyneeded.
Most important diagnostictool:HighPressureCystoscopy Issues at conventional hydrodilation Unreliable volume control • Vesico-ureteral (renal) reflux • Leakage through the urethra Uncertainties at pressure adjustment • Inaccurately defined zero level • Reference pressure must correspond with perivesical pressure • Adjustment of hydrostatic pressure is unexact NEW METHOD NEEDED
Improvedmethod:highpressureballoondilation of thebladder • Hyaluronate+ 2% Lidocainsolutionintothebladder • Balloonfilled upto 70cmH2O • Keeppressurefor 5 minutes • Quick collapse: ex vacuobleedings Standardized circumstances
After balloon dilation Unequivocal lesions visible Extended, deep coagulation (vaporization) of all mucosal glomerulations and ulcers Bladder catheter for 16-24 hours Adjuvant Hyaluronate + Lidocain instillations Repeated instillations weekly 2x for 2 weeks, weekly 1x for 4 weeks (8 times) Continuous follow up by questionaires and miction diary
Evaluation of pressure-volume relation: Always a bi-parabolic correlation! Suddenly decreasingpressure Bladderwallrupture !
Evaluation of pressure-volume relation: cysto-elastometric PC software
Use balloon dilation of the bladder instead of conventional hydrodilation Proved advantages: - no leakage - no v-u reflux - exact and reliable pressure controll - better visualisation of all mucosal lesion - simultaneous high pressure drug delivery Standardized parameters (pressure, time) Takehomemessage Summary of our experiences
