A 3,500-gram leiomyoma of the bladder: case report on a 3-year follow-up after surgical enucleation

Transvaginal Resection of a Bladder Leiomyoma Misdiagnosed with a Vaginal Mass: A Case Report and Literature Review

Bladder leiomyoma is a rare benign tumor and it could be easily misdiagnosed with many other pelvic diseases, especially obstetrical and gynecological diseases; abdominal, laparoscopic, and transurethral resection of bladder leiomyoma have been reported. Herein, we present a case of bladder leiomyoma misdiagnosed with a vaginal mass preoperatively; the mass was isolated, enucleated from the bladder neck, and removed transvaginally; to the best of our knowledge, this is the first case of intramural leiomyoma of bladder neck that has been enucleated transvaginally only without cystotomy.

Transurethral resection of a bladder leiomyoma: A case report

Benign mesenchimal tumour of the human bladder is rare. Insulin potentiation therapy mimics malignant tumours both clinically and radiologically. We present a patient we treated with transurethral resection (TUR) only. A 27-year old male patient presented to our clinic with frequency, dysuria and recurrent urinary tract infections. Magnetic resonance (MRI) revealed an endovesical bladder mass of 7 × 8 cm. We performed TUR in the same session for both diagnosis and treatment. The diagnosis was endovesical leiomyoma. Six months to a year after the operation, the MRI did not reveal disease recurrence. Even though TUR is recommended for smaller and endovesical tumours, we believe larger intravesical tumours may also be managed by TUR.

Transvesical enucleation of multiple leiomyoma of bladder and urethra

Although bladder leiomyoma is rare, this is the most frequent nonepithelial benign tumor of the bladder. Symptoms and treatment depend on location and size of the lesion as well. The optional treatment is a total enucleation or partial cystectomy, although in biopsy proved cases watchful waiting is an option, surgery should be considered as the tumor grows or symptoms are observed. The etiology of bladder leiomyoma is unknown. Uterine leiomyoma is known to be estrogen responsive. The premenopausal women are prevalent in the fourth decade.

Robot-assisted laparoscopic excision of bladder wall leiomyoma

Leiomyoma is the most frequent nonepithelial benign tumor of the bladder, and only about 170 cases have been reported in the literature. Most bladder wall leiomyomas are found incidentally and can be clinically followed if imaging and biopsy findings are consistent with the diagnosis. Resection is usually performed for symptomatic or enlarging masses and is indicated if the diagnosis is in question. We demonstrate imaging characteristics, port placement, operative technique, and surgical pathologic findings of the first reported case of robot-assisted laparoscopic resection of a bladder wall leiomyoma.

Bladder leiomyoma with right hydronephrosis

The authors describe one female patient with leiomyoma of the bladder who presented with female pseudoprostate and right hydronephrosis. A computed tomography (CT) of the pelvis revealed a soft tissue mass, circumferential and heterogenous in appearance with some calcification inside the mass. Bladder leiomyoma might be one of the differential diagnoses with CT imaging findings of female pseudoprostate.

Bladder leiomyoma presenting as voiding dysfunction: a case report

Mesenchymal tumors of the urinary bladder are rare, and the majority of them are malignant. We report a case of leiomyoma of the urinary bladder presenting with symptoms of voiding dysfunction. We performed surgical resection of the leiomyoma and repair of the bladder. Small capacity of the bladder with right vesicoureteral reflux was noted in outpatient department follow-up. A review of the relevant literature is also provided.

Leiomyoma of the urinary bladder: a case report

Leiomyoma of the urinary bladder is a rare tumor and constitutes 35% of benign mesenchymal bladder tumors. Herein, we report a case of leiomyoma of the bladder. A 32-year-old female was incidentally found to have an abnormal bladder mass on abdominal ultrasound during work-up for infertility. Bimanual examination then revealed a mass on the right side near the bladder neck area. On cystoscopic examination, an external compression mass covered with normal bladder mucosa could be seen at the right lateral wall. Computerized tomography revealed a homogeneous solitary tumor protruding into the urinary bladder from the right lateral wall without enlarged lymph nodes. Magnetic resonance imaging showed an intraluminal round mass at the right aspect of the urinary bladder, leading to suspicion of an intramural neurogenic or mesenchymal tumor. Surgical exploration was performed via a lower midline incision and a 5.0 x 4.5 x 2.2 cm mass was excised. The pathologic diagnosis was leiomyoma of the bladder. We discuss the diagnosis and management of leiomyoma of the bladder and briefly review the literature.

Leiomioma de vejiga. análisis de agregación de 90 casos

INTRODUCTION

Bladder leiomyomas (BL) are rare. Most publications regarding these tumours are reports of isolated cases; therefore they don't allow an evaluation of diagnostic and treatment procedures.

MATERIAL & METHODS

We preformed a pooled analysis of 90 cases of BL reported in the literature.

RESULTS

Mean age was 45.3 (19 to 85 years), 68 (75.6%) were women. Filling symptoms were the most frequently reported (50%), followed by voiding symptoms (24.4%). Twenty four patients (26.7%) were asymptomatic. Tumours were endoluminal in 46 patients (51.1%), intramural in 27 (30%) and extravesical in 15 (16.7%). A laparotomy was performed in 56 patients (62.2%), with enucleation in 29 (32.2%), partial cystectomy in 25 (27.8%) and total cystectomy in 2 (2.2%). A transurethral resection was preformed in 27 (30%) and a transvaginal resection in 5 (5.6%). Two patients underwent conservative treatment. In 3 cases there were reports of recurrence and one patient got a vesicovaginal fistula.

CONCLUSIONS

Although BL are rare, when evaluating bladder tumours, imaging techniques can make suspect of this neoplasm. Surgical treatment of these tumours has a very high success rate. Usually an enucleation or a transurethral resection is sufficient to render the patient tumour free, avoiding a more iatrogenic surgery.
