PD24-08 WIRELESS IMPLANTABLE RECHARGEABLE BLADDER PRESSURE SENSOR: CYSTOSCOPIC IMPLANTATION AND AMBULATORY DATA COLLECTION

urodynamic testing is low despite positive urine dipsticks or positive urine cultures in asymptomatic patients. METHODS: This was a retrospective review of consecutive urodynamic studies performed over a 12-month period. Urodynamic evaluation was cancelled only if patients were symptomatic. The primary objective was to identify the rate of fUTIs after the study and its correlation with positive urine dipsticks prior to the study. Urine cultures were also obtained to assess if bacteriuria impacted the rate of fUTIs. Additional variables studied included gender, medical condition, method of bladder management, the presence of vesicoureteral reflux and hydronephrosis. Urodynamic test findingswere reviewed to assess the quality of the study. Fisher’s exact tests were performed to determine statistical significance. RESULTS: A total of 175 urodynamic studies were performed. There were no test cancellations. One febrile urinary tract infection was noted after the procedure. Urine dipstick was positive in 41% (72/175) before the procedure, of these 86% had a positive urine culture (62/72). 53% (93/175) had a negative urine dipstick, of these 25% (24/93) had a positive urine culture. There was no statistically significant correlation between a positive urine dipstick or urine culture and a post-test fUTI. The influence of gender, medical condition, method of bladder management, vesicoureteral reflux or hydronephrosis was not significant on the rate of fUTIs after the study. In children under 14 years of age, the median capacity fill was 96% of expected capacity for age. CONCLUSIONS: Neither a positive urine dipstick nor a positive urine culture predicted a febrile urinary tract infection after urodynamic evaluation. In asymptomatic patients these tests may be unnecessary before the study.
