Unforeseen Encounters: Managing Intravesical Drains and Secondary Bladder Stones in Clinical Practice.

Urinary tract stones predominantly affect the kidneys and ureters, with bladder stones representing a smaller subset. Secondary bladder stones often arise from underlying pathologies such as bladder outlet obstruction, neurogenic bladder dysfunction, or the presence of foreign bodies within the bladder. We present a case of a 54-year-old male with a history of bladder stones and type 2 diabetes mellitus who presented with chronic urinary symptoms and penile swelling. Imaging revealed multiple bladder stones and a periurethral abscess secondary to a retained intravesical drain from a previous cystolithotomy. Surgical intervention included cystolithotomy, removal of the drain and stones, and management of associated urethral strictures. Postoperatively, the patient showed improvement in renal function and resolution of symptoms. This case underscores the importance of vigilant management during drain procedures to prevent complications like retained foreign bodies leading to stone formation and obstructive uropathy.
