[Bladder leiomyomas.]

Bladder leiomyomas are rare benign tumors; their common presentation are irritative and obstructive urinary symptoms. The treatment is complete surgical resection.

To present our experience in the diagnosis and the treatment of bladder leiomyoma.

A series of three clinical cases.

In our series, two patients were women and one was man. The mean age was 33 years. Two women presented with irritative urinary symptoms and palpation of a pelvic mass, and the man was asymptomatic. Ultrasound showed the presence of an adnexal mass with left hydronephrosis in a female patient, bladder tumor in another female patient and pelvic mass of unknown etiology in the male patient. CT scan and MRI demonstrated the bladder origin of the lesion. A biopsy confirmed a bladder leiomyoma. Surgical treatment was partial cystectomy in all patients, and in one of them, nephrectomy was performed. During follow-up, all patients were asymptomatic and without recurrence.

Imaging studies guide to diagnosis. Transurethral resection is recommended in lesions smaller than 3 cm. and enucleation or partial cystectomy in larger lesions. Prognosis is good.
