Three-dimensional ultrasonography of the urinary bladder: preliminary experience of assessment in patients with haematuria.

OBJECTIVE: To assess the value of three-dimensional (3D) vs two-dimensional (2D) ultrasonography (US) in the diagnostic evaluation of the urinary bladder in patients with haematuria. PATIENTS AND METHODS: In all, 42 patients with painless haematuria and/or irritative voiding symptoms were examined with 2D- and 3D-US. US was done with an Acuson Sequoia unit (Siemens Medical Sol. Mountain View, CA, USA) and the Perspective(R) 3D technique, to assess the presence of bladder lesions, including bladder cancer, bladder wall hypertrophy with trabeculation and diverticula, mucosal bladder folds or re-growth of the prostate mimicking a bladder tumour. The imaging findings were compared with cystoscopy and/or bladder biopsy. RESULTS: In 21 of the 42 patients (50%) cystoscopy with bladder biopsy revealed bladder cancer. Overall, 3D-US gave a correct diagnosis for 36 of 42 patients (86%). All 21 bladder cancers were correctly diagnosed, and 15 (71%) of the 21 benign bladder lesions were correctly identified. By contrast, 2D-US findings gave suspected bladder cancer in all patients. CONCLUSIONS: 3D-US is significantly more accurate than standard 2D-US in the diagnostic evaluation of patients with haematuria. Thus, this diagnostic technique might be useful for routine evaluation of the urinary bladder.

Assessing health care needs and clinical outcome with urological case complexity: a study using INTERMED.

Urinary tract symptoms and, particularly, urinary incontinence are often chronic and complex conditions that cause diagnosis, treatment, and management problems. In many cases, psychosocial factors contribute to the development of a chronic condition. The authors investigated whether INTERMED, an instrument for assessing case complexity and health care needs, was able to identify such complex cases, to estimate the amount of comorbidity, and to predict clinical outcome for 31 consecutive patients suffering from urinary tract symptoms. To assess clinical outcome, the authors used the American Urologic Association Symptom Score, the Brief Symptom Inventory, and the Hospital Anxiety and Depression Scale. On the basis of the patients' INTERMED scores, the authors distinguished between low-complexity patients (INTERMED score <21, N=25, 80.6%) and high-complexity patients (INTERMED score >or=21, N=6; 19.4%). Low-complexity patients had fewer depressive and anxiety symptoms, less distress, and better clinical outcome at their 3-month follow-up than high-complexity patients. The data confirmed the ability of the instrument to detect patients at risk of complex urinary tract symptoms and to predict clinical outcome.
