Abstract
BackgroundBladder tumours are rare in children, with only 0.38% of cases occurring in the first two decades of life. ObjectiveTo describe a long-term follow-up series of nine urothelial bladder tumours in children. Patients and methodsWe carried out a retrospective study covering the period from 1988 until 2005. We found that during this time, urothelial tumours had been diagnosed at our centre in eight patients (9 tumours) younger than 18 years old who reported an episode of haematuria. Diagnosis was attained through renal and bladder ultrasound in 85% of patients, and through cystoscopy under anaesthesia in 15%. All cases were treated by means of transurethral resection of the bladder, with ensuing follow-up using renal and bladder ultrasound and urinary cytology. MeasurementsPatients characteristics and outcome are evaluated. ResultsSingle exophytic tumours were present in seven (87.5%) of the patients, located either in the lateral wall or in the trigone; one patient showed two small tumours. The pathology was as follows: two G1Ta, one G1T1, one G2T1, and five G2Ta. There were no recurrences. ConclusionsTransitional cell carcinoma in childhood is of low grade and low aggressiveness. It has a good prognosis and recurrences are infrequent. We suggest performing a urinary cytology/cystoscopy every 6 months the first 2 years and urinary cytology/bladder ultrasound once a year.
