Initial experience of transurethral enucleation of submucosal bladder leiomyoma / 中华泌尿外科杂志

ABSTRACT

ObjectiveTo evaluate the clinical effecacy and safety of transurethral enucleation of submucosal bladder leiomyoma.MethodsAnalyze retrospectively the clinical data of 6 patients (2 male,4 female) of submucosal bladder leiomyoma. The mean age was 59 years (range 32- 78). The clinical manifestations included dysuresia in 3 cases, irritative bladder in 1 case, gross hematuria in 1 caes, and no clinical symptoms in 1 case. The mean course was 23 months (range 1 week-4 years). All the bladder tumors were indicated by ultrasonography, CT scan and cystoscopy, while 4 cases of bladder filling defects were showed by intravenous urogram. Before the tranaurethral enucleation of the bladder tumor, a deep needle biopsy and pathological examination were carried out to confirm the diagnosis of bladder leiomyoma. For the relatively small lateral leiomyomas, holium laser enucleation was carried out, while for the big ones, resectoscope enucleation was used to remove the mass. Biopsys were performed after complete removal of the tumor.ResultsTransurethral enucleation of 6 cases of submucosal bladder tumors were successful without any postoperative complication. All patients regained normal urination, and lower urinary tract irritation was relieved obviously and hematuria disappeared. No tumor recurrence or metastasis was found during the follow-up of 4 to 158 months.ConclusionsCystoscopy and transurethral biopsy are the most important methods for the diagnosis of submucosal bladder leiomyoma. The transurethral enucleation is a feasible and safe surgical technique for such patients with excellent results.
