“…Recently, laparoscopic partial cystectomy and robot-assisted partial cystectomy excision have been successfully applied for bladder leiomyoma treatment [5,21,22]. Silva-Ramos et al [23] performed a pooled analysis of 90 leiomyoma cases. Laparotomy was performed in 56 patients (62.2%), with enucleation in 29 (32.2%), partial cystectomy in 25 (27.8%) and cystectomy in 2 (2.2%).…”

Objectives: To investigate the feasibility and initial surgical outcomes of transurethral enucleation for 6 patients with bladder leiomyoma. Materials: Six patients (mean age 50.2, range [34–67]) with bladder leiomyoma underwent transurethral enucleation. In each case, the resectoscope was inserted into the bladder. A resecting loop was used to incise the urothelium along the surgical margin of the bladder tumor, and a push was given through the resecting loop to further separate the tumor until it was shelled off the bladder wall. The intact mass was then cut into pieces and flushed out. After the operation, irrigation therapy was given. Results: Surgery was performed successfully in all 6 patients. The mean size of the tumor was 3.9 cm (1.8–6.7 cm). The mean operation time was 60 min (30–100 min). The mean follow-up period was 14.8 months (2–30 months), and no evidence of recurrence was found in all cases. Conclusion: Transurethral enucleation is a safe, reliable, and effective surgical technique for selected patients with well-encapsulated tumors and is well suited for further pathological diagnosis and radical treatment.

“…Leiomyomas can remain asymptomatic for many years, reaching considerable size, unless they affect the normal function of the lower urinary tract [9]. Endoluminal tumors are symptomatic, presenting with urinary tract infections, hematuria, irritative symptoms (especially at the bladder neck), or obstructive symptoms, causing even acute bladder outlet obstruction secondary to a ISSN 1944-5792 (print), ISSN 1944-5784 (online) valve effect [5,6,9,10], as in our case. Intramural and subserosal tumors are, in general, asymptomatic and the diagnosis is incidental.…”

“…Nevertheless, imaging tests add important data that suggest the benign nature of these tumors, like the presence of a well-circumscribed lesion with homogeneous density, poor enhancement with contrast media, and normal, perivesical fat. There is no test that allows us to differentiate a leiomyoma from leiomyosarcoma; therefore, pathologic diagnosis is mandatory [5]. Leiomyomas are firm and rubbery in consistency, appear as whitish-gray, round to ovoid nodules with a spiral appearance of smooth-muscle fibers, and eosinophilic cytoplasm with less than 2 mitotic figures per high-power field.…”

“…Therefore, it can arise in any organ that contains this tissue. The most common localizations are the skin, womb, retroperitoneum, and genitourinary and gastrointestinal tracts [5,7,9]. In the genitourinary tract, it is most frequent in the kidney and bladder, especially at the trigone and bladder neck [7,9,10].…”

“…All samples obtained with a Tru-Cut needle and transurethral resection (TUR) were diagnostic, whereas the cold-cup biopsy samples showed a 50% false negative. Fine-needle aspiration biopsy was the least useful diagnostic tool [5].…”

Leiomyoma represents the largest subgroup of benign mesenchymal tumors that may arise anywhere within the genitourinary tract. Usual presenting symptoms include voiding symptoms such as obstruction and irritation. It can be diagnosed by careful physical examination assisted with ultrasound and endoscopic evaluation, but the confirmatory diagnosis is always histological. Bladder-conservative surgery is usually contemplated as the treatment of choice, be it transurethral resection or open surgery. This can include partial cystectomy due to the benign nature of the disease. Although the occurrence of this tumor is rare, it should be suspected with any urinary bladder tumor presenting with benign features. The prognosis is good with bladder preservative protocols.

Introducción Los leiomiomas son tumores benignos de músculo liso y pueden encontrarse en cualquier parte del tracto urinario, la mayoría se origina en la vejiga. Se presentan más en mujeres y deben ser considerados como diagnóstico diferencial en cualquier tumor de vejiga. El objetivo de este trabajo es reportar el caso de una paciente con un hallazgo incidental de leiomioma de vejiga y de localización infrecuente; además de considerarse una patología poco frecuente. Reporte de caso Paciente femenina de 40 años, ingresa por urgencias con cuadro de dolor abdominal en fosa iliaca derecha, valorada por cirugía general que realiza una presunción diagnóstica de apendicitis aguda y solicita estudios complementarios que evidencian proceso inflamatorio apendicular vs mucocele apendicular en la tomografía axial computarizada (TAC), por lo que se decide realizar apendicectomía por laparoscopia. Durante el procedimiento se evidencia lesión nacarada irregular dependiente de la cúpula vesical, por lo que se procede a interconsultar durante el procedimiento con el servicio de urología. El urólogo realiza cistoscopia sin evidencia de lesiones endoluminales. Se realiza excisión de la lesión junto con apendicectomía, sin complicaciones. La patología reporta leiomioma de vejiga. Discusión y Conclusiones Los leiomiomas de vejiga son tumores benignos poco frecuentes. Por tratarse de una patología que infrecuentemente presenta síntomas, puede hallarse incidentalmente y debe ser tenida en cuenta como diagnóstico diferencial en presencia de masas vesicales. Las imágenes son de gran ayuda diagnostica, sin embargo, será la histopatología quien aporte el diagnóstico definitivo. El tratamiento podrá variar de acuerdo al tamaño y localización del tumor.
