Transurethral resection of a bladder trigone leiomyoma: a rare case report

BackgroundBladder leiomyomas are rare and benign tumors of the bladder. They account for 0.43% of all bladder tumors, and only 250 cases have been reported in English literature. Based on the size and localization of the lesion, their symptoms vary considerably. Women seem to be more affected, and obstructive symptoms predominate. Surgical treatment is almost always highly effective, leaving a low recurrence rate.Case presentationWe present a clinical case of a 52-year old man with macroscopic hematuria and obstructive lower urinary tract symptoms due to a large bladder trigone leiomyoma. CT and MRI showed a well-defined large bladder leiomyoma and cystoscopy established the initial findings. The patient underwent successful transurethral resection of the lesion, and pathology findings confirmed the diagnosis.ConclusionsThis case report demonstrates that transurethral resection of a large bladder trigone leiomyoma is a feasible and successful procedure. Long term follow-up proves that there is neither scarring distortion of the bladder trigone area nor damage in the ureteral orifices, even though there was a thorough removal of the trigone wall.
