Hanging Bladder calculi Secondary to Misplaced Surgical Suture

Bladder calculi, a rare condition in the pediatric population, occur most commonly as a result of either migration from the kidney or urinary stasis in the bladder. we report the case of a 3-year-old boy with recurrent urinary tract infections (uti) secondary to bladder calculi formation on the sutures from a previous herniorrhaphy.a 3-year-old boy with previous history of herniorrhaphy presented with recurrent episodes of urinary tract infection, resistant to antibiotic therapy. physical examination was unremarkable. ultrasonography (us) showed an echogenic fixed intra-luminal lesion in the bladder. cystoscopic evaluation was performed and confirmed presence of calculi forming around several permanent silk sutures fixed to the bladder wall. the patient undergone cystotomy and the calculi were resected. the stone analysis revealed 80% uric acid calculi. the final diagnosis was of bladder calculi due to remnant suture from past herniorrhaphy.
