Great River Urology diagnoses and treats conditions of the kidneys, bladder and urinary tract in men and women, and all organs of the male reproductive system. Urologic diseases and disorders include:
  • Abnormalities of urologic organs
  • Cancers of the bladder, kidney, penis, prostate, testicles and urethra
  • Infections of the bladder, kidney or urinary tract
  • Kidney stones
  • Male infertility
  • Male or female incontinence
  • Male sexual dysfunctions
  • Prostate problems, such as benign prostatic hyperplasia, prostatitis or enlarged prostate
  • Sexually transmitted diseases

Because the male urinary and reproductive systems overlap, and the female urinary system is very close to the female reproductive system, disorders in one system often affect the other. Treatments for urologic conditions range from medicine to surgery.


Diagnostic procedures

CT scan

Computed tomography produces 3-D X-ray images of organs to determine abnormalities.

Needle biopsy

Guided by an ultrasound image, a urologist uses a device to insert a series of small needles into the prostate gland to take samples for laboratory examination. A local anesthetic is used.


To diagnose conditions in the lower urinary tract, a urologist inserts a cystoscope - a thin tube with a light and a tiny camera on the end - into a patient's urethra to visually examine the urethra, bladder or, in men, prostate.

Prostate-specific antigen (PSA)

Male patients age 65 and older usually are screened for PSA, a protein produced in the prostate. This test determines how much of it is in the blood. A high PSA may indicate cancer.

Flow test

A patient urinates into a machine that measures how fast the urine comes out. A slow flow rate may indicate an obstruction. A painless ultrasound examination determines of the bladder emptied completely.

Treatment procedures

Treatment procedures are performed at Great River Medical Center unless noted otherwise. Treatments performed by Great River Urology include:

Bacillus Calmette-Guerin Treatment

In the clinic, live tuberculin bacteria are inserted into the bladder to stimulate the body's immune system to attack specific types of bladder tumors, preventing regrowth.


A urologist removes the prostate through an incision in the abdomen. The urologist also may remove some nearby lymph nodes so they can be tested for cancer. 

Catheter changes

It is important that patients who use urinary catheters have them changed in the clinic regularly because catheterization can cause infections and chronic inflammation.

 Sling procedure for bladder control

To treat male or female incontinence, a urologist uses a minimally invasive procedure to insert support under the urethra, returning the patient's anatomy to its normal position.

Extracorporeal shock wave lithrotripsy

This noninvasive procedure breaks up kidney stones, which form when minerals in the urine combine to create hard deposits in a kidney or the bladder. A urologist focuses a high-intensity sound wave on the stone to pulverize it so the tiny pieces pass from the body easily.

 Transurethral resection of the bladder

To remove bladder cancers, a urologist inserts a cytoscope through the urethra into the bladder. The physician may remove a tiny tumor with a biopsy forceps. Larger tumors require use of an electric "knife" that burns away the tumor.

Kidney stents

A urologist places a device called a stent in a kidney or ureter to open a blockage. After the blockage is resolved, the stent is removed in the clinic.

 Transurethral resection of the prostate

In this treatment for benign prostatic hyperplasia, a urologist inserts a specialized cytoscope called a resectoscope through the urethra into the prostate to remove tissue thatis blocking the urethra.


When a kidney must be removed, a urologist removes it through one large incision or a laparoscopic procedure with several small cuts.


In the clinic, a urologist uses one of several simple, effective procedures to cut the vas deferens, which prevents sperm cells from leaving the body.
