This branch of urology deals with the management of benign and malignant diseases of the kidneys, ureters, bladder, and urethra that cause urinary tract obstruction. The most common benign conditions include lithiasis and strictures, while malignant ones include various cancers of the urinary tract. The urologists at our clinic, after evaluating the problem, are able to offer treatment, which may be conservative or surgical (endoscopic, laparoscopic, robotic, or open surgery).
