giving excellent pictures and also an assessment of kidney function. For better images of the lower urinary tract, contrast agents can be instilled from below. This is usually done with a cystoscope placed in the bladder. Through the cystoscope, a small tube can be threaded into the ureter thr...
Standardized Analysis of Kidney Ultrasound Images for the Prediction of Pediatric Hydronephrosis Severitydoi:10.1007/978-3-030-87589-3_38Congenital hydronephrosis, which is the dilatation of the renal collecting system, is common in children, resolving in most and treatable in the remaining 25%. ...
- 《J Ultrasound Med》 被引量: 1发表: 2015年 Etiology of Hydronephrosis in adults and children:Ultrasonographic Assessment in 233 patients Objectives: Hydronephrosis (HN) is dilatation of the collecting system of the kidney due to obstruction of urine outflow. This study intended firstly, to i....
 Giant hydronephrosis owing to ureteropelvic junction obstruction is a rare condition characterized by the accumulation of more than 1000 ml of urine in the pyelocaliceal system. It could mimic the other benign cystic kidney disease or other cause
(B) Abdominal computed tomography. Persistent hydronephrosis despite ureteral stent placement in right kidney. (C) Abdominal computed tomography. Persistent hydronephrosis after exploratory laparoscopy and right oophorectomy. (D) Ultrasound of right kidney. (D1) Mild hydronephrosis prior to reduction of ...
(5-9 mm), moderate (10-15 mm), and severe (>15 mm).5Data recorded consisted of demographics and ultrasound-derived serial measurements of kidney size and pelvic diameter. Change in grade of hydronephrosis within each patient was defined by the status of the more severely affected kidney. ...
Eighteen-gauge Chiba needles were used to achieve renal access under ultrasound guidance. A Cook 0.38 guidewire was placed into the renal pelvis on the side of surgery. Fascial dilators were used for dilation over the guidewire, and an F24 Amplatz sheath was placed in the kidney. Renal access...
Hence the first postnatal ultrasound is preferably done between 5-7 d after birth[12,26,27]. The exceptions to this caveat are: (1) Suspected lower tract obstruction e.g., Posterior urethral valves; (2) Severe bilateral hydronephrosis with or without hydroureter; and (3) Solitary kidney ...
The risk of developing UTI is greater in children with dilated ureter than in children with dilation limited to the kidney. Thus, these patients should also be placed on antibiotic prophylaxis based on prenatal Us and continued until imaging studies are complete [1,8,9,53,55]. ...
The aim of the study was to determine if the degree of hydronephrosis on focused emergency renal ultrasound correlates with kidney stone size on computed tomography. A retrospective study was performed on all adult patients in the emergency department who had a focused emergency renal ultrasound and...
