Uroradiology refers to radiology of the urinary tract. At NU Hospitals, IVU, MCU, RGU and Nephrostograms are the uroradiology tests performed.
IVU (Intravenous Urography): An IVU is a special x-ray series performed after an initial screening test, such as an ultrasound of the abdomen, has revealed the presence of some urinary abnormality in the urinary system. This series of special x-rays of your urinary system helps to visualize the entire urinary system. In this examination, a contrast injection is given through your vein in to the arm. This contrast is selectively absorbed by the kidneys and delineates the anatomy & function of the kidneys, ureter (tubes that connect the kidneys with the urinary bladder), & bladder. This helps your doctor to plan the course of management. With this test, it is also possible to assess approximately how well each kidney is functioning. Depending upon the findings on the x-rays, your doctor may prescribe further tests in order to obtain more details. The study will be carried out only after assessing the normal function of the kidney by way of a blood test called serum creatinine.
MCU (Micturating Cysto-Ureterogram): MCU is a special x-ray procedure performed to evaluate the bladder and the urethra in order to rule out any abnormalities in the bladder neck, narrowing of the urethra, or reflux of urine into the kidneys, etc. It is done only after basic blood & urine tests & ultrasound study of the urinary tract is completed. A suitable quantity of contrast medium is "injected" into the bladder through the suprapubic region or by a small tube inserted through urethra. While you are passing urine in standing position, X-rays will be captured. In case of female patient, who are pregnant / have a possibility of pregnancy, this procedure should not be done. This test also should not be done in case you have an active infection of bladder.
RGU or ASU (Retrograde or Ascending Urethrogram): is a special x-ray procedure performed to evaluate the urethra in order to rule out any abnormalities such as stricture (narrowing), etc. It is usually done in males. An RGU is conducted for patients with poor urinary stream, straining to pass urine, dribbling of urine, or injury to the genital region is suspected and after relevant investigations such as an ultrasound scanning, uroflowmetry tests. A local anesthetic solution is first introduced through the urinary outlet, in the reverse direction to the normal urine flow. Following this, the contrast medium is pushed by placing a catheter at the tip of the penis and this is captured on an x-ray film to document the findings. This test also should not be done in case you have an active infection of the urinary tract.
NEPHROSTOGRAM: Is a special x-ray procedure performed to evaluate the drainage of urine from the kidney, through the ureter into the bladder.Nephrostomy is a tube which is placed through the skin directly into the kidney to drain urine. The contrast medium is allowed to fill by gravity through the Nephrostomy tube and images are taken immediately and at 20 minutes to see if it drains into the bladder. This helps to doctor to plan the course of management by knowing the level of obstruction. This test also should not be done in case you have active infection of the urinary tract.
Certain specialized tests like CT (Computed Tomography) scan of the abdomen, MRI (Magnetic Resonance Imaging) of the abdomen, nuclear imaging tests like DMSA, DTPA, Bone scan, which are required in certain urological conditions are done at other places near to our Hospital.
Conventional ultrasound is in our hospital is done with LOGIQ P5 powerful system. It provides innovative technology and advanced features that set up to perform diagnostic imaging exams and the latest in ultrasound-guided procedures. The LOGIQ P5 offers the advanced technology and exceptional image quality needed for urology & nephrology practice. The LOGIQ P5 features, a variety of calculation packages, High Definition Speckle Reduction for image clarity, Cross X Beam Imaging for enhanced tissue / border differentiation in a stream-lined package, panoramic views. It also features a 15-inch high resolution LCD monitor, 3 active probes (4C, E8C & 12 L), an integrated hard-drive, transducer guides for renal and prostatic biopsies and procedures and DICOM software.
E8C urological endocavity transducer with guide to image and guide biopsies in the prostate in males and pelvic organs in females. Broadband 4C probe with guide to perform renal biopsies, Per Cutaneous Nephrostomy (PCN) access and procedures like perinephric and renal abscess / cyst aspirations. High frequency 12 L probe to perform vascular studies-penile Doppler, scrotal Doppler, peripheral arterial and venous studies, to assess feasibility and working of Arterio-Venous Fistula (AVF) etc
