Role of Ct Urography in Evaluation of Patients With Obstructive Uropathy: A Prospective Study of 50 Patients in a Urban Tertiary Care Hospital

Introduction: Obstructive uropathy is a relatively common clinical problem which if not treated timely can lead to irreversible renal damage. Therefore, accurate diagnosis is important for timely management. The purpose of present study is t Aim: o assess role Multidetector Computed Tomography (MDCT) urography in evaluation of obstructive uropathy. This prospective study was condu Materials and Methods: cted on 50 consecutive subjects presenting with evidence of unilateral or bilateral hydronephrosis and who were referred for CT urography for detection of site and cause obstruction. Out of 50 subjects, urinary obstruction was unilateral in 45 subjects ( Results: 90%) in our study. Only 5 subjects (10%) had bilateral urinary obstruction. Most common cause of urinary obstruction was urinary tract calculi which accounted for a total of 41 subjects (82%) (74 % had unilateral obstruction and 8% had bilateral urinary obstruction). Out of these, 9 subjects had calculi in the renal pelvis and 32 subjects had ureteric calculi. Second most common cause was urinary bladder masses which were causes of unilateral obstruction in 4 subjects (8%) and bilateral obstruction in 1 subject (2%). Other less common causes of urinary obstruction were PUJ obstruction in 2 subjects (4%) & ureteric stricture 2 subjects (4%) MDCT urography is very useful for complete evaluation of obstruc Conclusion: tive uropathy and allows rapid detection of level and cause of obstruction which is critical for timely and effective management.
