Invasive fungal bezoar requiring partial cystectomy

A 67-year-old man developed dysuria and position-dependent obstructive voiding symptoms after undergoing holmium laser ablation of the prostate (HOLAP) for benign prostatic hypertrophy. A large fungal (candidal) ball adherent to the bladder wall was removed by loop excision, but the bezoar recurred in 2 weeks despite systemic fluconazole and intravesical amphotericin B. A second attempt at endoscopic removal with ultrasonic lithotripsy, endoscopic graspers, and fulguration was also unsuccessful. The patient underwent open partial cystectomy to remove his invasive fungal bezoar. Convalescence was unremarkable. Urinalysis, culture, and follow-up cystoscopy after partial cystectomy demonstrated successful definitive treatment of the fungal ball.
