ABSTRACT
We reviewed and analyzed l3 cases of inverted papilloma that we have experienced during the last 7 years. from 1984 to 1990. Twelve patients were males and one patient was a female and their ages ranged from 42 to 75 with a mean age of 57. Gross hematuria occurred in 12 cases and intermittent urethral obstruction was associated in 3 cases and urethral obstruction without hematuria occurred in 1 case. Urine cytology was negative in all cases, except the one which showed suspicious cytology for malignancy. Cystocopy revealed polypoid appearance in 12 cases and papillary in one. All of the masses were single and pedunculated with a stalk and were located mainly in trigonal area in 12 of 13 cases (92%). The diameter of the masses ranged from 1.0cm to 6.0cm. Transurethral resection was performed in all cases. There was no case of recurrence or malignant transformation during the follow-up period with a mean of 26 months. In conclusion, inverted papilloma is suspected by its peculiar predilection site and appearance without difficulty and controlled by transurethral resection alone. When it is completely resected, follow-up by benign neoplasm is considered to be sufficient.
