Objective To analyze the typical clinical manifestations and imaging characteristics of renal pelvic carcinoma.Methods The clinical data in 69 cases of renal pelvic carcinoma verified by postoperative pathology in this department of the hospital from July 2013 to November 2016 were retrospectively summarized to analyze its typical clinical manifestations,imaging features and treatment regimens.Results All the cases were hospitalized due to hematuria and presented gross hematuria.The detectable rate of B-ultrasonic examination was 71.43 ％,which of computed tomography urography(CTU) was 84.21％ and which of intravenous urography(IVU) + kidney ureter bladder(KUB) was 70.27 ％,which of retrograde pyelography(RP) was 90.32 ％,which of flexible ureteroscope(FU) was 91.67 ％,the pathological detection rate of biopsy tissue by this method was 58.33 ％ and detection rate of fluorescence in situ hybridization was 79.07 ％.Sixty-nine cases all were performed the retroperitoneal laparoscopy combined with hypogastric incision renal pelvic carcinoma radical operation,postoperative pathological examination verified renal pelvis carcinoma.Conclusion Flexible ureteroscope examination has the highest definite diagnosis rate of renal pelvic carcinoma,but the pathological positive rate of biopsy tissue by this method is not ideal;the definite diagnosis rate of RP and CTU were secondary,urinary system B-ultrasonic examination,FISH and KUB+IVP can serve as the preliminary screening and postoperative re-examination means of renal pelvic carcinoma.
