title: [Symptom of asymmetric bladder filling defect in the presence of ureteral prevesical calculus].
abstract: Examining descending cystograms in 357 patients with renal colic caused by calculi in the ureteral prevesical portion revealed that 34 (9.5%) had the asymmetric bladder filling defect which was ipsilateral to the calculus. In 11 patients with the calculi strangulating in the ureteral ostium, the outlines of filling defect took the form of a rim around the calculus. Echography provides direct ultrasonic evidence for a calculus in 186 (52%) patients and the asymmetric shape of the bladder only in 1 patient. The described symptom caused by urinary detrusor spasm and, in some cases, by perifocal tissue edema at the site of the ureteral ostium with its strangulated calculus may serve as indirect evidence for a lower ureteral calculus.
