A Rare Case Report of Infertility Due to a Giant Hair-bearing Urethral Stone in a Urethral Diverticulum

Urethral stones are rare, accounting for less than 1% of all urinary system stones.These stones may present with obstructive symptoms or remain asymptomatic.Hair-bearing urethral diverticula, which can form after surgical interventions such as hypospadias repair, are an uncommon cause of urethral stone formation.However, urethral stones leading to infertility are extremely rare.A 38-year-old male patient presented to the urology outpatient clinic with complaints of infertility.Physical examination revealed a palpable mass in the penoscrotal region.Further evaluations and imaging identified this mass as a urethral stone within a hair-bearing urethral diverticulum.The patient's history revealed a childhood hypospadias repair.Open surgery was performed for stone removal and diverticulectomy.Semen analysis at the six-month postoperative follow-up showed an improvement in semen volume from 1 ml preoperatively to 2.5 ml, reaching normal levels.Additionally, nine months after the procedure, the patient's spouse was confirmed to be pregnant.Long-term follow-up revealed no postoperative complications.This case highlights the importance of considering urethral pathologies in infertile patients with a history of urethral surgery.Such conditions can be effectively treated with open surgery, potentially restoring fertility.
