Endourologists have always strived to decrease the morbidity of surgical procedures and improve patients’ quality of life. Endourology, initially defined as “the closed and controlled manipulation within the urinary tract,” has favorably encompassed all minimally invasive techniques, including laparoscopy, for the betterment of patients’ care. The field of urologic oncology is not an exception to this leading force of least invasiveness. Based on the principles of the oldest oncologic endoscopic surgery, namely, transurethral resection of bladder tumors, the endoscopic approach to superficial upper-tract transitional cell carcinoma has evolved for the past two decades.
