IVU, MCU , RGU, and Nephrostograms Tests

Uroradiology refers to radiology of the urinary tract. At NU Hospitals IVU, MCU, RGU, and Nephrostograms are the uroradiology tests performed.Uroradiology

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 into 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 on 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 the urethra. While you are passing urine in standing position, X-rays will be captured. In the 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 the bladder.

RGU or ASU (Retrograde or Ascending Urethrogram):

 RGU 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 the 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 the 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 is required in certain urological conditions are done at other places near to our Hospital.

Ultrasound Services : 

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 streamlined 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 the guide to image and guide biopsies in the prostate in males and pelvic organs in females. Broadband 4C probe with the guide to performing 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 the feasibility and working of Arterio-Venous Fistula (AVF) etc

COMPUTERIZED TOMOGRAPHY (CT) (or ‘computerized axial tomography’ (CAT) scan) : 

COMPUTERIZED TOMOGRAPHY (CT) uses a computer that takes data from several X-ray images of structures inside a human’s body and converts them into pictures on a monitor.

Tomography is the process of generating a 2-dimensional image of a slice or section through a 3-dimensional object. Similar to looking at one slice of bread within the whole loaf.

The Siemens Somatom Scope is a Whole Body CT Scanner with fast scanning speed, low dose, and excellent image quality providing a complete range of CT applications. It has many, advanced and newer features such as CARE Dose 4D, IRIS, SureView reconstruction algorithm and Adaptive Signal Boost technology which help reduce the dose, reduce noise and significantly improve image quality.

CT scanning generates cross-sectional images of the human body, which allows Radiologists to evaluate the internal organs in great clinical detail. Any abnormality is easily picked up on a CT Scan. It can also be used to generate 3D reconstructions, volume reconstructed images etc., which facilitate better understanding of clinicians.

Almost all organs can be scanned with a CT Scanner including:

  • Brain, Orbit, PNS and Neck.
  • Chest, Abdomen & Pelvis.
  • Joints and spine with 3D CT.
  • CT Angio: Brain, Carotid, Pulmonary, Aorta, Renal, and Peripheral.
  • CT Urogram.
  • Virtual Colonoscopy and Bronchoscopy.
  • Dental CT.

Computerized Tomography (CT) - uroradiology

Our CT SOMATOM Scope includes cockpit technology. Our CT most importantly enables us to comply with the NEMA XR-29 Smart Dose Standard and ensures a safer imaging experience for patients.

Our CT, SOMATOM Scope utilizes Siemens’ iterative reconstruction in image space (IRIS) technology, which accelerates image reconstruction while reducing noise and artifacts. It also includes Siemens’ fully assisting scanner technology (FAST) and combined applications to reduce exposure (CARE) applications that help reduce radiation exposure and standardize the CT imaging process.
