Ultrasound as an alternative to intravenous urography in prostatism

Is Pre‐operative Imaging of the Urinary Tract Worthwhile in the Assessment of Prostatism?

“…Jensen et al (1988b), in a urodynamic study, showed that PMRV had no predictive value for post-operative outcome. No previous imaging study has examined the value of imaging PMRV in predicting the need for or the outcome of operation, although Fidas et al (1987) commented that knowledge of a large residual volume may influence surgical management. Powell et al…”

“…Patients in acute retention and those with haematuria were excluded. All patients presenting to the urologists with uncomplicated prostatism underwent routine imaging; this included ultrasound of the urinary tract with a full bladder, ultrasound estimation of the bladder volume immediately after micturition (calculated as 0.6 x oblique length x height x width) and plain films of the abdomen and pelvis (KUB) as proposed by Fidas et al (1987). All ultrasound examinations were performed by radiologists, usually of consultant grade, although some were performed by registrars and senior registrars under consultant supervision.…”

“…We suggest that no routine pre-operative imaging need be performed in patients presenting with Imaging of the urinary tract in patients presenting with prostatism is controversial and several workers (Bruskewitzet al, 1982;Fidas et al, 1987;de Lacey et al, 1988;Timoney et al, 1989) have questioned the need for intravenous urography or ultrasonography to detect abnormalities of the renal tract or assess PMRV. Jensen et al (1988a) suggested that a Q max > 15 ml/s indicated the likelihood of a poor post-operative outcome.…”

The Value of Ultrasound Scanning of the Upper Urinary Tract in Patients with Bladder Outlet Obstruction

“…In the assessment of bladder outlet obstruction, ultrasound has often been contrasted with intravenous urography (Matthews et al, 1982;Lilianfield et al, 1985;Fidas et al, 1987;Stavropoulos et al, 1988). Ultrasonography of the bladder is cheap, safe and reliable and can be carried out in the urological department, but few studies have been made of its value in assessing the upper urinary tract.…”

Ultrasonography and Doppler studies in the diagnosis of renal obstruction

“…3), and retroperitoneal fibrosis or malignancy [6]. The sensitivity of US in detecting collecting system dilatation caused by obstruction has led to its adoption as the first renal imaging method in a variety of clinical settings, particularly in patients with renal failure [4], prostatism [7], or pelvic tumours, and in transplanted kidneys.…”
