Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The investigator's hypothesis is that smoking induces inflammation in the bladder wall. This may predispose to the development of Interstitial cystitis(IC) / bladder pain syndrome(BPS). Previous research has linked one the Platelet Activating Factor - PAF to interstitial cystitis. The investigators will study a limited number of patients to determine whether PAF is stable in urine and whether special precautions (for example - immediate freezing in liquid nitrogen) is necessary for accurate measurement of PAF in the urine. Patients who are presenting for an office visit will be asked to donate at least 50 ml of urine. A separate group of patients who are scheduled for surgery, are also being asked to donate around 25 ml of urine during surgery. No patient data other than group assignment, whether they smoke or if they have or not have interstitial cystitis will be recorded.
