Anterior lumbar spinal surgery involves making an incision through the abdomen of the patient in order to access the spine. During this process, several internal structures are pushed aside in order to gain access. One of these structures is the ureter, whose function is to drain urine from the kidney to the bladder. One potential complication that can arise from this is dilation of the kidney - known as hydronephrosis. The aim of this study is to identify whether hydronephrosis after Anterior Lumbar Interbody Fusion (ALIF) is complication, in order to bring this to the attention of health care professionals when considering this kind of surgery.
A total of 40 patients who have had ALIF surgery will be invited to have an ultrasound scan of their kidney on the side where the operation was performed (where the scar is). Should hydronephrosis of this kidney be detected, the investigators will go on to scan the second kidney. Should hydronephrosis be detected the patient will be given a letter to take to their General Practitioner (GP) advising them to be referred to a Urologist.

This study focuses on the relationship between prophylaxis antibiotics and frequency of urinary tract infection in children diagnosed with antenatal hydronephrosis. Hydronephrosis is the m...
It has previously been found that there is no correlation between degree of hydronephrosis and presence of reflux; however this is oftentimes the criteria physicians use to obtain a VCUG.
An Emergency Department Targeted Ultrasound (EDTU) is an ultrasound examination performed by an emergency department physician, instead of a radiologist or ultrasound technician. EDTU is i...
The purpose of this study is to detect new urinary biomarkers that can be used as predictors on renal function in congenital hydronephrosis caused by unilateral ureteral obstruction (UUO) ...
Primary objective was to determine efficacy of Alfuzosin in the treatment of children and adolescents 2-16 years of age with newly diagnosed or progressive hydronephrosis due to elevated d...
Renal ultrasound (US) accurately identifies hydronephrosis, but is less sensitive than computerized tomography (CT) for the detection of ureterolithiasis. This study investigated whether the presence ...
Long-term evolution of residual hydronephrosis after successful pyeloplasty is not common. In this report, we have studied new ultrasound parameters, and have investigated the frequency of residual hy...
An 8-month-old neutered male ferret was presented for vaccination and preventive treatment for adrenal gland disease. Abdominal ultrasound revealed severe bilateral hydronephrosis and hydroureter. Exc...
Hydronephrosis is the one of the most common congenital abnormalities of urinary tract. The left kidney is more commonly affected than the right side and is more common in males.
Risk factors for urinary tract infection (UTI) in children with prenatal hydronephrosis (PNH) are not clearly defined. Our study aim was to describe incidence and identify factors associated with UTI ...
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.

Cancer or tumors of the URETER which may cause obstruction leading to hydroureter, HYDRONEPHROSIS, and PYELONEPHRITIS. HEMATURIA is a common symptom.
Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.
