Congenital stenosis of a ureteric orifice causes cystic enlargement of the intramural portion of the ureter. This is termed ureterocele (Bailey and Love, 1959).We have been unable to find any previous report of the demonstration of ureterocele by grey-scale ultrasound and record here the findings in a case where ultrasound was instrumental in establishing the diagnosis.During investigation for prostatism on a 75-year-old man, routine intravenous urography revealed a right sided hydronephrosis and a collection of contrast in the region of the lower end of the right ureter (Fig. 1). A possible lucentfilling defect was identified within this collection of contrast. Concentration of the contrast medium in this region and in the bladder was poor owing to dilution by retained urine. It was considered likely that a right ureterocele was present and grey-scale ultrasound examination was performed to confirm the diagnosis.The patient was examined in a supine position using a Nuclear Enterprises Diasonograph NE 4200 with grey-scale display and 2.5 MHz 19 mm transducer.The ultrasound scan (Fig. 2) clearly outlined a ureterocele and the lower portion of the dilated ureter was also shown. Multiple echogenic structures were noted within the ureterocele and probably confirm the radiological impression of calculi here. In addition, a posterior bladder diverticulum containing a calculus was also noted (Fig. 2) The prostate was confirmed to be enlarged.These findings were not confirmed at surgery since the patient died of unrelated disease shortly after these investigations. |
