Diagnosis of early renal pelvic cancer / 中国医师进修杂志

Objective To probe the most effective method for the diagnosis of early renal pelvic cancer. Methods Ultrasound, introvenus urogram (IVU), retrograde pyelography, CT, magnetic resonance urography and transurethral ureteropeyloscopy were performed, and the accuracy rate was evaluated. Results The accuracy rate of IVU, retrograde pyelography, CT, transurethral ureteropeyloscopy, MRU and ultrasound were 89%, 94%, 80%, 50%, 40% and 22% respectively. Conclusions IVU and retrograde pyelography are the common and necessary diagnostic methods for early renal pelvic cancer. Transurethral ureteropeyloscopy is an invasive method and used as a final method when other methods fail to identify the disease.
