[Primary adenocarcinoma of the ureter associated with hypocalcemia: report of a case].

A case of primary adenocarcinoma of the ureter, associated with severe hypocalcemia in a 73-year-old man is reported. The patient had undergone left nephrectomy for pyonephrosis due to a ureteral stone, 29 years previously. On November 4, 1986, he visited the hospital with dysuria and overflow incontinence as the chief complaints. He was admitted with suspicion of prostatic carcinoma, but prostatic stones and chronic prostatitis were proven. However, urine cytology showed adenocarcinoma cells, and a ureteral tumor was found at the right ureterovesical junction. On December 10, right partial ureterectomy, total cystectomy and right ureterocutaneostomy were performed. Moderately differentiated, invasive adenocarcinoma was found at the right ureteral end, 1.5 cm in length and in part poorly differentiated transitional cell carcinoma was present continuously to the adenocarcinoma. Hypocalcemia was cured easily with activated vitamin D3. The patient, 9 months after the operation, is apparently free of the ureteral tumor.
