Tests & Screenings

Detecting the source of your urological problem is one of the first steps in proper treatment. At Nacogdoches Medical Center, we offer a wide range of tests and screenings to properly diagnose a urological condition. See below for common diagnostic tests and screenings.

24-Hour Urine Collection

This procedure involves collecting urine in a special, refrigerated container for 24 hours. The information obtained from analyzing this urine can be used to diagnose a variety of kidney, urinary or other physical conditions.

Computer Tomography (CT OR CAT) Scan of the Kidney

A CT scan of the kidney is an imaging procedure that uses X-rays and computer technology to create multi-perspective images for diagnostic purposes.

Cystoscopy for Women

This is a procedure in which a flexible, lighted tube, called a cystoscope, is inserted into the urethra to visualize the inside of the bladder. It can also be used to irrigate, suction and biopsy the bladder.

Intravenous Pyelogram (IVP)

IVP involves injecting a dye into the arm. This dye flows through the kidneys, ureters and bladder and is visualized by X-ray to assess urinary system function.

Kidney Biopsy

This procedure involves removing a small piece of kidney tissue. The biopsied tissue can be tested for cancer and other conditions.

Kidney Scan

This procedure involves injecting a tracer substance into the arm and tracing its path through the kidneys, ureters and bladder via X-ray to assess urinary system function. This test is performed instead of an intravenous pyelogram (IVP) when the patient is allergic to the dye used for an IVP.

Kidney Ultrasound

This procedure uses sound waves and computer technology to form an image detailing the size, shape and blood flow of the kidneys.

Kidney, Ureter and Bladder (KUB) X-ray

A KUB X-ray provides an image of the abdominal region that includes the kidney, ureter and bladder. It is used to diagnose issues with the urinary system.

Prostate Biopsy

This procedure used to remove suspicious tissue from the prostate. During the biopsy, a fine needle is used to collect the sample.

Prostate/Rectal Sonogram

This is a procedure that uses ultrasound technology to help assess the size, shape and condition of the prostate gland as well as the rectum. A sonogram is often performed to check for signs of prostate cancer.

Renal Angiogram

Also referred to as arteriograms, this procedure is used to assess the blood flow of the kidneys. Arteriograms are X-rays taken of the blood vessels.

Renal Venogram

This procedure uses contrast dye as a diagnostic tool in order to provide physicians with information on the circulatory health of the kidneys. The contrast dye is used to better visualize the veins within the kidneys.

Retrograde Cystography

Retrograde cystography is a detailed radiology examination of the bladder. Contrast dye is placed into the bladder through the urethra and X-rays are taken to reveal how well a bladder empties.

Retrograde Pyelogram

This is a urologic procedure in which contrast dye is injected into the ureter to allow for better visualization of the kidneys and urethra. The contrast flows up the bladder to the kidneys, which is the opposite of normal urine flow.


This is a diagnostic tool used to determine if there is an obstruction to the flow of normal urine output. This procedure is noninvasive and is used to calculate the flow of urine overtime.
