title: Day case hematuria diagnostic service: use of ultrasonography and flexible cystoscopy.
abstract: OBJECTIVE
  To assess the efficacy of a day case diagnostic service employing ultrasonography and flexible cystoscopy in the evaluation of patients presenting with painless gross hematuria.
  
  
  METHODS
  From July 1994 to June 1997 a prospective study was conducted for 312 consecutive patients presenting with painless gross hematuria. They were evaluated in a day case diagnostic service setting, where ultrasonography and flexible cystoscopy were performed together with other laboratory investigations. Intravenous urography was subsequently performed for possible additional diagnostic information.
  
  
  RESULTS
  Eighty-one urinary malignancies were detected in 78 patients; 51 were carcinoma of the bladder, and the next most common was renal cell carcinoma (n = 15). Definitive diagnoses were made in 68 patients and an abnormality was noted in 9 other patients after the day case workup. The day case diagnostic workup has led to highly selective use of computed tomography scans with high diagnostic yield; intravenous urography only added important diagnostic information, not available from the earlier workup, in 9 patients.
  
  
  CONCLUSIONS
  Day case diagnostic service is a feasible arrangement. By combining ultrasonography and flexible cystoscopy, most carcinomas were diagnosed and abnormalities detected. Such a service enhances rapid completion of diagnostic workup, and operations for surgical conditions can be scheduled more promptly.
