ABSTRACT
Objective To investigate the effect of endoscopic management of upper tract urothelial carcinoma (UTUC),and evaluate the indication and clinical value of postoperative prophylactic pelviureteric instillation chemotherapy.Methods Patients who met the inclusion criteria included elderly patients,patients who could not tolerate radical surgery,patients with renal insufficiency or needed dialysis after removal of the kidney,patients with bilateral UTUC,patients with tumor≥3 cm in diameter but could be completely resectted under ureteroscopy who required to preserve renal function.Surgical procedure was successful.The ureteral stents were placed,and prophylactic ureteral infusion chemotherapy via the retrograde transvesical ureteric catheterisation was conducted 1-2 times one week at 2 days after surgery.40 milligram of pirarubicin hydrochloride or epirubicin hydrochloride was dissolved in 40 milliliter sterile water for the prophylactic infusion chemotherapy.These instillations were completed within 40 minutes.Results Totally,9 patients (3 males and 6 females) aged 60-86 years,mean age of (69.7±6.4) years,were enrolled in this study.The carcinoma of the renal pelvis was found in 2 cases and ureteral tumors in 7 cases.In pathological results,ureteral polyps was found in 1 case,papillary ureteral neoplasm with low malignant potential in 2 cases,urinary tract epithelial carcinoma in 4 cases (1 case with poorlydifferentiation,1 case with well-differentiation,2 cases with urinary tract epithelial cancer),and 2 cases were lack of pathological reports because of too few pathologic specimens.4 patients received adjuvant chemotherapy by instillation successfully,and lumbago,fever or other complications were not found.Patients were followed up for a mean period of 15 moths (4-31 months).Only 1 patient had recurrence of bilateral ureteral tumor 15 months after surgery,and no tumor recurrence was found in other patients.Conclusions Endoscopic management is a safe and effective in treating UTUC,which can preserve renal function by avoiding nephrorectomy in some patients.The instillation chemotherapy after endoscopic management is safe,which has a satisfactory effect,but further validation in a large clinical sample is needed.Patients with tumor resection under ureteroscopy who cannot obtain the pathology results need to be closely followed up.
