Abstract

Objective The aim of this work was to assess the value of multislice computed tomography (CT) urography in patients presenting with obstructive uropathy. Background Obstructive uropathy is a structural impedance to the flow of urine anywhere along the urinary tract. Multidetector computed tomography urography (MDCTU) has the advantage of being able to detect not only the level of obstruction but also its cause, including urinary stones, pelviureteric junction stenosis, ureteric strictures, ureteric injury, retroperitoneal fibrosis, and pelvic masses. Patients and methods This study included 30 patients of variable ages, complaining of urinary tract obstruction manifestations referred from urology and urosurgery clinics. MDCTU was performed for all patients. Results Causes of obstructive uropathy as detected by MDCTU were as follow: 14 (46.6%) cases caused by urinary tract stones, four (13.3%) with urinary bladder masses involving ureteric orifices, three (10%) with pelviureteric junction obstruction (PUJ) obstruction, three (10%) with compression of ureters, three (10%) with ureteric injuries, two (6.6%) with bladder neck obstruction, and one (3.3%) case with ureteric stricture. Conclusion MDCTU enabled an accurate diagnosis of the level of obstruction and its etiology, including nephroureterolithiasis, pelviureteric junction stenosis, ureteric strictures, ureteric injury, retroperitoneal fibrosis, and pelvic masses.
