In study from January 2001 to December 2004 we prospectively performed 557 examinations in 356 patients with clinical suspicion for the presence of bladder tumor. All patiens underwent cystoscopy and sonography with transabdominal multifrequency probe (2-5 MHz) on 2102 Hawk (BK-Medical, Denmark) imaging system. All positive, suspicious or inconclusive endoscopic findings were histologically verified. Primary superficial urothelial carcinomas were diagnosed with sensitivity 85% and positive predictive value 100%. In reccurences sonography had sensitivity 52% and positive predictive value 90%. Sensitivity and positive predictive value of sonography in infiltrating tumors was calculated 96% 100% respectively. We recorded that transabdominal sonography is suitable noninvasive method for primary diagnosis in patients with bladder tumors and follow-up of patients after treatment of superficial urothelial carcinomas. Due to limited sensitivity ultrasonography cannot be single diagnostic method cystoscopy remains the gold standard. High positive predictive value allow indication of cystoscopy in general or spinal anesthesia in patiens with positive sonography without outpatient cystoscopy.
