SONOGRAPHIC STUDY OF PATIENTS WITH URINARY TRACT INFECTION Mohamed Sabry Saliem; Tamer KamaI and Maha Salah Yousscf Paediatric, Radiodiagnosis and Clinical Pathology Departments, Benha Faculty of Medicine, Zagazig University ABSTRACT This study included 60 infants and children having urinary tract infection (UTI) With no history of previous attacks. They were picked up from the out-patient paediatric clinics of Benha Faculty of Medicine Hospital. They were subjected to careful history taking, thorough clinical examination, urine cultures and clony counts. Ultrasonographic scanning was done for all patients and those with abnormal findings were evaluated radiologically. Ultrasonography detected urinary tract abnormalities in 25 patients (41.67%), with obstructive changes in 16 patients (26.67%). The obstructive lesions demonstrated by ultrasonography were; uretral obstruction in 6 patients (10%), uretro pelvic obstruction in 4 patients (6.66%), renal stones in 3 patients (5%), uretro pelvic stones in 2 patients (3.33%) and uretro vesical stone in one patient (1.66%). Intravenous pyelography revealed that uretral obstruction was due to stricture or stone, 3 cases each (5%). The non obstructive lesions were urinary bladder stones in 4 patients (6.66%), renal stones in 2 patients (3.33%), unilateral duplication of renal pelvis and ureter in 2 patients (3.33%) and unilateral multi cystic kidney in one patient (1.66%). We concluded that the first diagnosed attack of UTI could be a sign of serious underlying pathology such as obstructive uropathy, so we recommend to use ultrasonographic scanning, being a safe and noninvasive technique in all cases of UTI as soon as diagnosed for a better management.
