External Urethral Meatus Stone in Women with Urinary Retention: A Rare Case Report

Ureteral stones are commonly found in the kidneys, ureters, and bladder, whereas urethral stones are rare, accounting for less than 1% of all urinary tract stone cases. The prevalence is approximately 7 cases per 100,000 individuals, with a significantly higher occurrence in men, at a male-to-female ratio of 13:1. This research aims to report a rare case of urethral stone in a female patient and evaluate the effectiveness of manual stone extraction with local anesthesia as a minimally invasive treatment option. This research employs a case research approach by analyzing the clinical presentation, diagnostic findings, and treatment outcomes of a 55-year-old woman who presented at the emergency department with acute urinary retention lasting two hours, accompanied by genital pain. Physical examination revealed no abnormalities in the abdomen, but a stone was identified at the external urethral meatus. The patient underwent manual stone extraction under 2% lidocaine local anesthesia using nalfuder. The procedure involved fragmenting the stone into smaller pieces before complete removal, successfully restoring normal urination. The findings emphasize the rarity of urethral stones in female patients and highlight acute urinary retention as a key clinical manifestation. The successful outcome of manual extraction with local anesthesia demonstrates its efficacy as a minimally invasive approach, offering valuable insights for improving the management of urethral stones. This research contributes to the medical literature by supporting manual extraction as an effective and less invasive alternative in appropriate cases.
