ABSTRACT: A 52-year-old woman was referred to our institute for the evaluation of a tumor in her pelvic cavity. The tumor seemed to have arisen from the bladder or urethra, and bilateral iliac lymphadenopathy was seen. Her urethral mucosa looked intact according to the results of cystourethroscopy. Histopathological examination of the biopsy specimens showed clear-cell adenocarcinoma. She underwent radical cystourethrectomy with complete pelvic lymph node dissection and the construction of a bilateral ureterocutaneostomy. Macroscopically, the tumor had arisen from the trigone of the bladder, and histopathological examination of the tumor revealed adenocarcinoma exhibiting solid clear cells with glandular and papillary patterns. The tumor had infiltrated perivesical structure (pT3a), and metastases in multiple pelvic lymph nodes were recognized (pN3). Postoperatively, three courses of systemic combination chemotherapy with 5-fluouracil (FU) and cisplatin, along with a total of 45 Gy of irradiation during the second course of chemotherapy, were conducted. No evidence of the disease has been seen 28 months after the surgery.

ABSTRACT: A 59-year-old female was referred to our institute for urinary tract infection with septicemia, thrombocytopenia, and hyperglycemia. Plain abdominal X-ray and computed tomography (CT) showed emphysema at the left renal parenchyma and urinary tract along with the perirenal inflammatory changes. These findings suggested emphysematous pyelonephritis in the early phase of occurrence in a diabetic patient. Transurethral catheterization of the left ureter was immediately performed, and occluded cloudy urine was drained. Ureteral stent was left indwelt transurethrally for easy accession in case of occlusion. E. coli was cultured in drained urine. Administration of antibiotics, insulin, and anti-coagulant was performed, and drained urine became clear in several hours. General condition and laboratory findings were improved normally in a week, and CT did not reveal the emphysematous change of the left renal unit at the 11th hospital day.

ABSTRACT: A total of 110 patients were treated with primary transitional cell carcinoma (TCC) of the urinary bladder from 1990 to 2000. During the follow-up period, which was for at least two years, four patients (3.6 percent) had subsequent upper urothelial cancer at an average of 61.5 months after initial treatment of the bladder tumor. Two of the four patients received transurethral resection several times, and the remaining two patients underwent radical cystectomy for the initial bladder tumor. The histopathological findings of subsequent upper urothelial cancer were almost the same as those for the initial bladder tumor. One patient had accompanying carcinoma in situ (CIS) and the other had adenocarcinoma with TCC. Since 1) high grade, 2) multiple, 3) recurrent and 4) occupational bladder tumors, 5) concomitant CIS, 6) vesicoureteral reflux and 7) tumor invasion of the intravesical ureters have been reported to be risk factors for developing subsequent upper urothelial cancer, patients with bladder tumors who have these risk factors should be followed-up closely.
