Summary

Lower urinary tract leiomyomata are rare, benign tumors. Imaging can differentiate them from malignant masses, and treatment is only needed for symptom relief, not tissue confirmation.

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Area of Science:

  • Urology
  • Pathology
  • Oncology

Background:

  • Leiomyomata are rare benign tumors originating from smooth muscle.
  • Lower urinary tract leiomyomata can cause obstructive voiding symptoms.

Purpose of the Study:

  • To review experience with lower urinary tract leiomyomata.
  • To determine if presentation, exam, and imaging can stratify treatment.

Main Methods:

  • Retrospective review of 13 female and 10 male patients (1995-2008).
  • Focus on clinical presentation, cystoscopic findings, imaging, and operative approaches.

Main Results:

  • Symptomatic patients had larger lesions, were more likely female, or had midline/bladder neck lesions.
  • Cystoscopy revealed submucosal polypoid lesions without mucosal involvement.
  • No recurrences were observed after complete excision.

Conclusions:

  • Lower urinary tract leiomyomata are benign and distinguishable from malignant lesions via imaging.
  • Resection is indicated solely for symptom relief, not for diagnosis.
  • Conservative management is prudent for asymptomatic, benign-appearing lesions.
