چکیده
BACKGROUND Hydronephrosis (HN) or calycial dilatation is the most common prenatal urologic abnormality. The aim of this study was to identify the possible changes in demographic and clinical manifestations of infantile HN in previously and recently diagnosed patients. METHODS 193 children with infantile HN admitted to Ali-asghar Children's Hospital in two different periods (group 1; 1997-2003, and group 2; 2005-2011) were evaluated in this cross-sectional study. Variables such as time at diagnosis, gender, clinical manifestations, etiology, laterality, grade, and associated anomalies were also evaluated. RESULTS The mean age at diagnosis was 32.3± 42.6 (group 1) and 21.4± 36.4 (group 2), respectively. 69.8% of patients were males. 75% of prenatally diagnosed patients were asymptomatic. Urinary tract infection was the most common symptom, followed by pain, hematuria, and decreased renal function. Obstruction in ureteropelvic junction was the most common etiology, accounting for 39.6% of all patients. Neurogenic bladder, vesicoureteral reflux, nephrolithiasis, and ureterovesical junction obstruction were the other common etiologies. 55.5% of all patients had unilateral HN, which was more common on the left side. No significant difference documented between two groups of patients, except for mild HN (23.7% vs. 39%), which was more common in newly diagnosed patients (p= 0.001). CONCLUSION There was no changing trend in demographic and clinical manifestations of infantile HN. However, the severity of infantile HN has been decreased significantly in recently diagnosed patients.

متن کاملUltrasonography by emergency physicians in patients with suspected ureteral colic.
We performed a prospective study of patients with suspected ureteral colic to evaluate the test characteristics of bedside renal ultrasonography (US) performed by emergency physicians (EPs) for detecting hydronephrosis, and to evaluate how US can be used to predict the likelihood of nephrolithiasis. Thirteen EPs performed US, recorded the presence of hydronephrosis, and made an assessment of th...
متن کاملQuantitative analysis of infantile ureteropelvic junction obstruction by diuretic renography.
Infantile hydronephrosis detected by ultrasonography poses a clinical dilemma on how to treat the condition. This article reports a retrospective study to evaluate infantile hydronephrosis due to suspected ureteropelvic junction (UPJ) obstruction by means of standardized diuretic renography and to speculate its usefulness for quantitative assessment and management of this condition. Between Nov...
متن کاملIn Response to “Sensitivity of Emergency Bedside Ultrasound to Detect Hydronephrosis in Patients with Computed Tomography-proven Stones”
INTRODUCTION Non-contrast computed tomography (CT) is widely regarded as the gold standard for diagnosis of urolithiasis in emergency department (ED) patients. However, it is costly, time-consuming and exposes patients to significant doses of ionizing radiation. Hydronephrosis on bedside ultrasound is a sign of a ureteral stone, and has a reported sensitivity of 72-83% for identification of uni...
