Urethral and paraurethral leiomyomas in the female patient

A diagnostic approach of various urethral diseases using multimodal imaging findings: comprehensive overview

In clinical practice, urethral diseases are not as frequent as conditions affecting other components of the urinary system. Radiological imaging tests, such as retrograde urethrography, CT, MRI, and PET/CT, along with patient history, are crucial for accurately assessing relatively rare urethral lesions. This article aimed to provide a comprehensive overview of urethral lesions, from traumatic changes to neoplasms, and discuss the multimodal imaging findings of various urethral lesions that radiologists should know. To this end, the normal imaging anatomy of the urethra and a step-by-step approach that can be used in clinical practice have been presented to help in the systematic understanding of urethral lesions.

A urethral leiomyoma presenting with dysuria: A rare case report

RATIONALE

Leiomyoma is a benign smooth muscle tumor which is rarely found in urethra. We hereby report a case of a 44-year-old female who presented with complaints of dysuria.

PATIENT CONCERNS

A 44-year-old female patient presented to the urology outpatient clinic with symptoms of dysuria. The patient described the presence of a protrusion from the urethra during urination.

DIAGNOSIS

Urethral leiomyoma.

INTERVENTIONS

Physical examination confirmed a solid urethral mass. CT scan and USG reports indicated that the mass originated from the mid-urethra with vascularity at the base. We performed a complete resection of the urethral mass. The patient was discharged after 3 days of observation.

OUTCOME

During a follow-up after 1 month, the patient reported improved urinary flow and no occurrence of hematuria. The patient recovered well after discharge.

LESSON

Urethral leiomyoma is a rare benign tumor that is often misdiagnosed in clinical practice. Diagnosis requires careful clinical examination. Surgical removal usually works well. It is important to remember that in some cases of acute urinary retention, it can be caused by a complete obstruction of a mass in the urethra. Urologists should be more cautious and experienced in handling such cases.

Transvaginal excision of vaginal paraurethral leiomyoma: A video case report

INTRODUCTION AND HYPOTHESIS

Vaginal leiomyomas are uncommon benign tumors of the genital district that appear as a circumscribed, mobile, and nontender mass along the vaginal tube. The gold standard of vaginal leiomyoma management is surgical treatment. We aimed to present a clinical case of vaginal leiomyoma successfully treated throughout a transvaginal excision and layered repair.

METHODS

A 44-year-old woman was referred to our division for vaginal bulging symptoms and dyspareunia. Clinical examination revealed a 4-5 cm hard bulging mass in the anterior vaginal wall, below the urethra, compatible with vaginal leiomyoma. After proper counseling, the patient was admitted to transvaginal leiomyoma excision plus primary layered repair.

RESULTS

No surgical complications were observed. The indwelling catheter was removed the day after the surgery. The patient was successfully discharged home on postoperative day 1. The patient is currently asymptomatic and there are no signs of recurrence.

CONCLUSION

The procedure was successful in obtaining anatomical repair and relieving symptoms. This approach represents a valid procedure for the surgical management of this uncommon condition.

Long-term follow up of paraurethral leiomyoma: A case report and literature review

BACKGROUND

Paraurethral fibroid is a rare condition. To date, there is no unified protocol to guide long-term follow up in this condition. This study reviewed case reports and summaries published in the last 10 years and focused on the management plans and follow up of patients with paraurethral fibroids.

CASE PRESENTATION

We report the case of a 44-year-old woman who presented with urinary symptoms. Clinical examination and magnetic resonance imaging revealed an approximately 3 × 3 cm mass which was considered as a paraurethral fibroid. Complete surgical excision was performed. The patient was discharged with no postoperative complications. Histopathology confirmed the diagnosis of a benign leiomyoma.

CONCLUSIONS

Paraurethral fibroid is a rare condition which can be diagnosed with a high level of certainty based on clinical examination and imaging. A multidisciplinary team which includes experienced radiologists and urogynecologists or urologists who have the expertise to perform vaginal surgery with urethral reconstruction is essential for definitive management. Long-term follow up for expected possible complications is advisable. Further research with a larger number of cases is needed to recommend an evidence-based protocol for management of paraurethral fibroid.

Urethral Masses

Urethral and periurethral masses in women include both benign and malignant entities that can be difficult to clinically differentiate. Primary urethral carcinoma is rare and the optimal treatment modality may vary depending on the stage at presentation. Because cancer-free survival is poor, clinicians shouldhave a high index of suspicion when evaluating a urethral mass. Some benign-appearing urethral masses may be safely observed. Surgical resection is an effective option that should be used based on patient preference and symptoms, and for suspicious lesions.

What is this vaginal bulge? An atypical case of vaginal paraurethral leiomyoma. A case report and literature systematic review

AIM

Vaginal paraurethral leiomyomas are uncommon benign tumors of the female genitourinary tract. We report a case of anterior vaginal paraurethral leiomyoma. Furthermore, we performed a systematic review of the literature to provide information that can help the physicians in the diagnosis and management of women with this rare pathology.

METHODS

A case of anterior vaginal paraurethral leiomyoma in 53-year-old, primiparous, caucasian woman with history of pelvic pressure, vaginal bulging and overactive bladder symptoms, was described. Furthermore, a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement was performed between January 1, 2000 to Dec 30, 2019. Only articles that reported cases of vaginal or paraurethral leiomyoma (b) case series and case reports with literature review were included.

RESULTS

we screened a total 2281 records; 70 articles published from 2000 to 2019 were included.

CONCLUSION

Vaginal paraurethral leiomyoma is a rare benign tumor of the vagina with a wide spectrum of symptoms and good prognosis. The recurrence and transformation into malignant condition are rare. Histopathological examination is the gold standard for diagnosis, but MRI and US can be help to define the size and localization of the tumor. Management requires surgical vaginal excision in the majority of cases; however, abdominal approach could be considered when it is large and located high in the vagina.

Recurrence of urethral leiomyoma: A case report

Urethral leiomyoma is an infrequent benign tumor. Much more infrequent is recurrence. It has been described in exceptional cases. We report a rare case of a 46 year old woman who had a surgery for a urethral leiomyoma eight years ago. Now, she presents with nodulation in her vagina with no other symptoms. The patient underwent surgical excision of the tumor, and pathological examination revealed an recurrence of urethral leiomyoma.

A very large leiomyoma of the urethra: A case report

INTRODUCTION

Leiomyomas are benign mesenchymal tumours of smooth muscle origin. They are the most common uterine masses in women of reproductive age group and may be related to the hormonal status. Urethral leiomyomas are very rare. According to the literature, the mean diameter of the urethral leiomyomas is 3.7 cm.

CASE REPORT

We report a case of a very large leiomyoma of the urethra. A 40-year-old women woman was admitted to our department for a giant vaginal mass. She complained of haematuria, dysuria, recurrent urinary tract infections and dyspareunia. The physical evaluation demonstrated a 6 × 5.5 cm neoformation involving the distal tract of the urethra. The patient underwent an ultrasonography and then a magnetic resonance that suggested the diagnosis of leiomyoma. The neoformation was excised through a suburethral incision.

CONCLUSIONS

The patient was discharged after 3 days and no intraoperative and postoperative complications occurred. The Foley catheter was removed after a week. The patient was continent to urine, and at 6 months follow-up, the patient was symptom free and no recurrences occurred.

Paraurethral Leiomyoma in a 20 Year-old Woman: A Case Report

We present the case of a 20 year-old woman with a vulvar mass, found to be a paraurethral leiomyoma. She subsequently underwent supermedial-approach paraurethral mass excision, distal urethral reconstruction and cystourethroscopy. Paraurethral leiomyoma make up approximately five percent of urethral tumors. This case depicts the presentation and treatment of a paraurethral leiomyoma in one of the youngest women reported in the literature.

Imaging Diagnosis of Urethral Leiomyoma, usual Tumour at an Unusual Location

Leiomyomas are benign tumours of smooth muscle origin and are the most common uterine masses in females of reproductive age group. Extrauterine leiomyomas are also encountered occassionally and most commonly they involve the genitourinary tract. Leiomyomas arising from urethral smooth muscle are exceptionally unusual which can pose a diagnostic dilemma. Patients usually present with urinary complaints and an intraluminal soft tissue mass bulging from urethral meatus. We are presenting the imaging findings of leiomyoma of distal urethra presenting as a perineal mass with histopathological correlation.

Leiomyoma of the seminal vesicle: a rare case

Leiomyomas though common benign tumors of smooth muscle cells are extremely rare in the male genitourinary tract. We present a case of an elderly male who presented with complaints suggestive of urinary bladder outlet obstruction since 1 year. His evaluation showed it due to a tumour arising from the left seminal vesicle. Excision of the tumor was done which was diagnosed on histopathology as leiomyoma. A brief case report and review of literature is being presented.

Leiomyoma of the female urethra-a rare tumor: case report and review of the literature

Leiomyoma is a benign smooth muscle tumor which is rarely found in urethra. Only a handful of cases have been reported in the literature. We hereby report a case of urethral leiomyoma in a twenty-seven-year-old female who presented with intermittent hematuria. Mass was completely excised with a rim of normal tissue. Patient remained asymptomatic with no evidence of recurrence in followup.

Female Urethral Reconstruction

Female urethral strictures are rare; thus, the literature describing stricture management in women is sparse. Although urethral dilation continues to be performed at a high frequency in women despite lack of proven efficacy, this procedure is used for a variety of voiding complaints other than stricture. Hence, the long-term utility of dilation and urethrotomy for urethral stricture in women is unknown. This review describes the various urethroplasty techniques used in the management of female urethral stricture. Although grafts using a dorsal approach have been shown to be feasible in women, ventral flap techniques offer good long-term outcomes with minimal morbidity. Acute and delayed management of pelvic fracture-associated urethral distraction defects in women is also described. Unlike in men, immediate urethroplasty in women should be performed once the patient is hemodynamically stable.

Female urethral stricture disease

Female urethral stricture disease is a rare entity. The most common etiologies are traumatic injury, iatrogenic injury, and inflammatory disease resulting in periurethral fibrosis. Hallmark symptoms are frequency and urgency, and may also be dysuria, hesitancy, slow stream, incontinence, and recurrent urinary tract infections. Female bladder outlet obstruction is a difficult entity to define, and the subset representing stricture disease may also be elusive. The diagnosis of female urethral stricture disease is usually based on symptoms, meatal appearance, and difficult instrumentation of the patient. Other testing, such as urodynamics, voiding urography, or cystoscopy, may be helpful. Treatment options are conservative management with dilatation, endoscopic treatment, or open repair with various tissue flaps or grafts. Considerable controversy surrounds the efficacy of urethral dilatation in women with voiding dysfunction.

Benign masses of the female periurethral tissues and anterior vaginal wall

Due to their rarity, benign masses of the periurethral tissues and anterior vaginal wall are poorly understood. Arriving at the proper evaluation and treatment is challenging because many of these masses have similar presenting signs and symptoms, as well as overlapping differential diagnoses. The literature regarding these lesions mainly consists of level III evidence, mostly involving case reports and series. Clinical management has traditionally been based on established surgical principles and expert opinion. This review presents the pertinent embryologic and anatomic background for these benign masses, as well as other pertinent etiological processes. Furthermore, the most current evidence is reviewed regarding the differential diagnosis, evaluation, and treatment for each mass.

Leiomyomas of the female urethra and bladder: a report of five cases and review of the literature

Through the experience of five cases of leiomyoma developed in the female bladder and urethra with a review of the literature, we have made an effort to characterize the association of symptom with the size and location of the tumor and demonstrate an appropriate treatment. The study population was composed of patients who underwent surgery for bladder or urethral leiomyoma in our hospital from March 1990 to April 2005. Their medical records were reviewed retrospectively concerning the symptom, size and location of leiomyoma, the result of cystoscope and radiological examination, surgical method, pathologic report, complications, and recurrence. Four cases were diagnosed as urethral leiomyoma and one case as bladder leiomyoma. All patients with urethral leiomyoma were admitted for the chief complaint of a palpable tumor. When the tumor size was small, if it was located on the lateral side of the urethra, it was asymptomatic, but if located in the midline, it presented irritative or obstructive symptom. When it was big, if located on the lateral side, it presented irritative rather than obstructive symptom, and if located in the midline, it presented obstructive symptom. One case of bladder leiomyoma was discovered incidentally during ultrasonic exam. In all five cases, surgical removal was performed and complications or recurrence were not detected afterwards. Bladder and urethral leiomyomas are very rare and cause diverse manifestations from asymptomatic to irritative or obstructive symptom. It is presumed that the location and size of the tumor are associated with symptom. Unless it is the case with severe hemorrhage or obstructive acute renal failure, immediate surgery is not required. However, it is desirable to distinguish leiomyoma from malignant or other benign tumors by surgical biopsy or removal.
