Abstract:
Objective To summarize the clinical features,diagnosis and treatment of autologous urologic neoplasms in renal transplant recipients.Methods A retrospective analysis on the clinical data of 25 renal transplant recipients was done in our center.The onset time of new neoplasms was between 29 to 72 months after transplantation,with an average of 48.2 months.Intermittent hematuria was the first symptom in 23 patients,and the rest two cases were diagnosed through routine examination. The pathological diagnoses of thee cases were renal carcinoma,which were treated by transperitoneal laparoscopic radical nephrectomy.Eight cases were diagnosed as having renal pelvic tumor,which was treated by radical resection for the renal pelvic carcinoma.Fourteen cases were diagnosed as having bladder cancer,which was treated by transurethral resection of bladder tumor (13 cases) or radical cystectomy (one case).All patients were subjected to surgical treatment.The dosage of MMF,CSA/Tacrolimus was decreased to 1/2-2/3 of their original dosage. Sirolimus was used in place of calcineurin inhibitors in four patients.Immunosuppressive regimes and adjuvant therapy were given after surgery treatment.Results Twenty-five patients were followed up for 12-84 months.Contralateral renal carcinoma combined with lung and chest multiple metastases occurred in one case after radical nephrectomy,who died after targeted therapy 6 months later.Two patients with lymph node metastasis died 14 months and 20 months after surgery respectively.The rest 22 patients were closely followed up,whose creatinine remained 98-163μmol/L.Conclusion More attention should be paid to patients with hematuria after renal transplantation to screen the autologous urinary neoplasms.Patients should be treated with surgical procedures,and immunosuppressive regimens should be adjusted postoperatively.
