ABSTRACT
Fungal bezoars (fungal balls) are rarely reported in the upper or lower urinary tract. They can be the cause of severe morbidities such as urinary tract obstruction, renal failure and fungaemia. Hereby, we present a rare case of a male patient who underwent transurethral resection of bladder tumour (TURBT), and during his postoperative period, he was diagnosed with bladder fungal bezoars adherent to his resection area. The fungal bezoars were covering an extended area of the right lateral bladder wall, including the right ureteric orifice and causing right urinary tract obstruction. Those findings were manifested only after a relooked cystoscopy and histological evaluation.We aim to present a rare example of fungal bezoars mimicking other pathologies in the urinary tract and review the current literature for similar documentation. We underline the necessity of follow-up examinations for urologists performing TURBT surgeries, including urinalysis, imaging modalities and cystoscopy.

We presented an extremely rare entity of 'hybrid' oncocytoma and collecting duct (Bellini) carcinoma. The intratumoural coexistence of benign and malignant cells may lead to false diagnosis and suboptimal treatment of an aggressive tumour. Diagnosis may be challenging if only based on imaging modalities. Even the established value of targeted renal biopsy may be questioned in such scarce cases. Consequently, active surveillance for small renal tumours shall not considered a widely safe management.
