Transitional cell carcinoma in untreated adult bladder exstrophy: A rare case report

Untreated adult bladder exstrophy is a very rare entity and has a higher risk of developing bladder cancer. A 41-year old man with acute kidney injury and bilateral hydronephrosis was consulted to Urology Division. Examination revealed bladder exstrophy with suspected malignancy. The incisional biopsy result showed transitional cell carcinoma which is the most common bladder cancer, but extremely rare in bladder exstrophy. Radical cystectomy and urinary diversion with double-barrel ureterocutaneostomy were conducted. Abdominal defect was closed with surgical mesh application and rotational skin flap. The patient was well recovered with improved quality of life.
