[Necrotic bladder following radiotherapy for cervical carcinoma].

BACKGROUND

In contrast to proctitis, vaginitis and acute radiation cystitis are late complications of pelvic radiation therapy, rare, more severe and irreversible.

CASE DESCRIPTION: A 66-year-old patient presented with progressive renal failure ten years after radiotherapy for carcinoma of the cervix. Ultrasound investigation revealed a bilateral hydroutereronefrosis (grade 4), with narrowing of the ureterovesical junctions and a diffuse thickening of the urinary bladder wall. Biopsy of the bladder wall showed extended necrosis. The diagnosis was a necrotic bladder with bilateral ureteral stenosis without local symptoms. Lifelong renal urinary drainage was indicated.

CONCLUSION

Late obstructive urological complications, such as bladder necrosis and urethral obstruction, are rare following radiotherapy for cervical carcinoma. Ultrasound follow-up can contribute to the early detection of these complications and intervention can prevent further loss of renal function; however, this would not be cost-effective because of the low incidence rate and because these complications appear in the long term.
