Urodynamics are used to evaluate how your bladder and urethra work. They help to determine the cause of your urinary tract problem. The pressures in the bladder and urethra are measured during the study and are used to formulate the best plan for you.
After you have emptied your bladder into the special commode, small catheters will be placed into your bladder and into your vagina (or rectum). These special catheters measure the pressure in your bladder. Your bladder will be filled using the catheter in your bladder and you will be asked to cough and strain at different points during the filling.
Once your bladder is full, you will be asked to empty your bladder in the special commode again with the catheters in place. Most patients can void easily with the catheters in place since the catheters are so small.
This procedure lasts about an hour.
Cystoscopy is using a small telescope-like device, called a cystoscope, to look at the inside of your bladder and urethra.
Your urethra will be cleaned with an antibacterial soap and the cystoscope will be inserted through your urethra into your bladder.
Your bladder is filled with water and viewed carefully. After your doctor has examined your bladder, it is emptied and the cystoscope is removed. A sample of fluid may be sent to the laboratory for examination.
