Urology, Lithotripsy & Urology Oncology
Joseph Motta, M.D., Division Chief
The Urology Center of Excellence treats urologic diseases and conditions that affect both male and female adult patients. Our center treats adrenal and kidney diseases, bladder conditions, prostate problems, medical and surgical management of stones and more. We offer less-invasive treatments for many conditions.
Stock Wave Lithotripsy
In this completely noninvasive form of treatment, an energy source generates a shock wave that is directed at a urinary stone within the kidney or ureter. Shock waves are transmitted to the patient either through a water bath, which the patient is placed in, or using a water-filled cushion placed against the skin. Ultrasound or fluoroscopy is used to locate the stone and focus the shock waves. The repeated force caused by the shock waves fragments the stone into small pieces. This procedure is most often performed under heavy sedation, although general anesthesia is sometimes used. Once the treatment is completed, the small stone particles pass down the ureter and are eventually urinated away. In certain cases, a stent may need to be placed up the ureter just before the procedure to help the stone fragments pass.
Certain types of stone (cystine, calcium oxalate monohydrate) are resistant to shock wave lithotripsy and usually require another treatment. In addition, larger stones (generally greater than 2.5 centimeters) may break into large pieces that can still block the kidney. Stones located in the lower portion of the kidney also have a decreased chance of passage.
Cystoscopy enables the doctor to take a direct look inside your bladder through a small camera inserted through the urethra. It is a common test used to look for causes of bleeding in the urine and some other bladder problems.
