Primary bladder carcinoma presenting during pregnancy in 3 cases.

We report 3 cases of primary transitional cell carcinoma of the bladder presenting during pregnancy. Only 10 such cases have been reported in the literature. Patient age ranged from 23 to 24 years at 15 to 24 weeks of gestation. Only 1 of the 3 patients presented with gross hematuria and this was initially mistaken as vaginal bleeding. Initial diagnosis in all cases was made with sonography. Diagnosis then was easily confirmed by cystoscopy and treatment was uneventful. Transurethral resection did not present a problem. All patients had single papillary superficial tumors (stage Ta, grades 1 and 2). Pregnancy was not affected in any case. Diagnosis and prompt treatment are emphasized.
