[Hematuria during pregnancy caused by bladder tumour. Report of 2 cases].

Tumours of the urinary bladder are rare in pregnancy. We report two such cases presenting with gross hematuria, but one of them was initially mistaken as vaginal bleeding. Patients age was 41 and 27 years old, at 26 and 18 weeks of gestation respectively. Diagnoses were made with cystoscopy and sonography. Tocolytics agents were employed. Both of the tumours were managed succesfully by transurethral electroresection. Raquianesthesia was employed in both. There were no adverse effects on the pregnacies. Transurethral resection is a safe procedure during pregnancy. The pathology diagnoses were inverted papilloma in the first case and papillary urothelial neoplasm of low malignant potential in the other one. The literature is reviewed.
