To determine the potential of transabdominal ultrasonography to demonstrate the presence or absence of bladder infiltration in patients with cervical carcinoma.
A descriptive study.
The oncology unit in a tertiary medical centre serving a black rural and urban population.
110 consecutive unstaged patients with histologically proven cervical carcinoma.
The findings-designated normal, suspicious or infiltration-on ultrasonography and cystoscopy.
Transabdominal bladder ultrasonography in this study had a sensitivity of 100%, a specificity of 76,5%, a positive predictive value of 60,4% and a negative predictive value of 100% compared with cystoscopy in the evaluation of the bladder for infiltration by cervical carcinoma.
Although not accepted as a staging procedure by the International Federation of Gynecology and Obstetrics, transabdominal bladder ultrasonography can be used as a triage for bladder infiltration by cervical carcinoma in a cost-effective way, referring only those patients with abnormal cystoscopic and biopsy findings.
