DISCUSSION Significant postvoid residuals can result in symptoms of urinary frequency, nocturia, overflow incontinence, and recurrent urinary tract infections. Measurement of this residual volume is important to rule out both neurologic abnormalities and/or obstructive voiding disorders. In managing patients with prostatic gland enlargement, it is very useful in the initial assessment and monitoring of clinical [...]
The variables L, T, Dt, and Dl were considered in estimating the actual bladder volume. The relationship between the volume and these variables was examined. The scatter plots of volume against each of the variables revealed curvilinear relationships (Figure 2).
Fifty-four consecutive patients with symptoms and clinical signs of prostatic gland enlargement had transabdominal ultrasonography at the Department of Radiology, University of llorin Teaching Hospital, llorin, between January and August 2001. Of these, two were excluded from the study, as bladder catheterization was impossible due to concomitant urethral stricture. Patients with in-dwelling bladder catheters due [...]
INTRODUCTION Significant postvoid residual (PVR) urine volume is a frequent manifestation of benign prostatic hyperplasia. Assessment of this volume forms an important routine investigation, as serial measurements may indicate clinical progress. Bladder catheterization is, however, widely regarded as the gold standard of measurement. Nevertheless, it carries the risk of infection and trauma to the urethra. [...]
