Primary carcinoma of the renal calyx is extremely rare. The present study reported nephron sparing endoscopic treatment for primary carcinoma of the renal calyx. An 81-year-old female presented with a 1-year history of intermittent painless gross hematuria. Computed tomography and X-ray of the urinary tract were unable to definitively identify any lesion. Flexible ureteroscopic examination revealed a tumor with epicenter in the lower calyx of the right kidney, with additional involvement around the calyx. Biopsies were obtained and pathology revealed low-grade urothelial carcinoma. Considering additional co-morbidities, the patient elected to undergo endoscopic management with thulium laser. The present report described the feasibility of flexible ureteroscopic thulium laser resection for the treatment of renal calyx carcinoma.
