The widespread use of prenatal ultrasound results in an increased recognition of fetal hydronephrosis. To determine clinical characteristics and postnatal outcome of fetal hydronephrosis, we performed a retrospective study in children diagnosed as having fetal hydronephrosis between 1990 and 2001. 341 children with 427 dilated kidneys were included. Dilatation of the renal pelvis was caused by ...

Widespread use of fetal ultrasonography is accompanied by more frequent detection of antenatal hydronephrosis. Therefore, sonographic evaluation of neonates with a history of antenatal hydronephrosis is becoming more widespread. As an initial postnatal non-invasive imaging modality, ultrasonography is used to screen for persistence of hydronephrosis, determine the level and severity of obstruct...

Although Imperforate hymen is a rare condition, it is the most common obstructive anomaly of the female genital tract. The early diagnosis of this condition requires a high index of suspicion in newborns and in females without a history of menarche. Hydronephrosis is a known but rare complication of an imperforate hymen. Hereby we preset 2 cases of premenstrual adolescent with urinary retention...

Introduction: Hydronephrosis can be either unilateral or bilateral, often due to ureteropelvic junction (UPJ) or ureterovescial junction (UVJ) obstruction. UPJ and UVJ can coexist in the same ureter, varying in severity, and the presence of both can make appropriate diagnosis more difficult. As far as we know, there are no reports of concurrent bilateral UPJ and bilateral UVJ obstructions. Case...

This study was performed to validate the procedure of transarterial embolization of the renal artery (TAE-RA) using iohexol-ethanol solution in rabbits with unilateral experimental hydronephrosis and to evaluate the embolized kidney and contralateral normal kidney using B-mode ultrasonography and color Doppler ultrasonography. Experimental hydronephrosis was induced at 17 days after ligation of...

hydronephrosis occurs as a congenital or an acquired condition following obstruction of the urinary tract. in this study, a four month old male holstein calf with emaciation, growth retardation and a poor dry scruffy hair coat was examined because of remarkable distention of right abdomen. at necropsy, right kidney was hydronephrotic as a very big fluid-filled round pelvis with the presence of ...

OBJECTIVES To report the decline of renal function after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC) patients and to develop a nomogram to predict ineligibility for cisplatin-based adjuvant chemotherapy (AC). METHODS We retrospectively analyzed 606 consecutive Chinese UTUC patients treated by RNU from 2000 to 2010. We chose an eGFR of 60 and 45 ml/min/1.73 m(2)...

INTRODUCTION Supporting an "ultrasound-first" approach to evaluating renal colic in the emergency department (ED) remains important for improving patient care and decreasing healthcare costs. Our primary objective was to compare emergency physician (EP) ultrasound to computed tomography (CT) detection of hydronephrosis severity in patients with suspected renal colic. We calculated test characte...

Experimental hydronephrosis induced by partial ureteral obstruction at 3 wk of age causes hypertension and renal impairment in adult rats and mice. Signaling by Ephrin receptors (Eph) and their ligands (ephrins) importantly regulates embryonic development. Genetically modified mice, where the cytoplasmic domain of the EphA4 receptor has been substituted by enhanced green fluorescent protein (Ep...

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...
