Urine Cytology as Seen in Uyo, Nigeria: How Relevant Is It to Medical Practice?

AIM

The aim of this study is to know the pattern of urine cytology (UC) requests seen in Uyo and how relevant they were to the management of the patients.

MATERIALS AND METHODS

This retrospective study was carried out in the Department of Pathology, University of Uyo Teaching Hospital. The extracted data from the cytology registers were analyzed using the Statistical Package for the Social Sciences version 17.

RESULTS

A total of 46 patients did UC during the period. The patients were aged between 21 years and 90 years, with a mean age of 56.89 ± 14.65. Thirty (67.4%) were male. The age group of 60-69 years accounted for most cases (37.8%). Suspicion of bladder cancer was the most common indication as it was seen in 28.9% ( = 13) of cases. Thirty-eight cases (84.4%) were referred from urology clinic, 2 each (4.4%) from general outpatient clinic, general surgery clinic, and from gynecology clinic. In 44.4% ( = 20) of cases, the cytological diagnosis was inflammatory smear, while the UC was normal in 24.4% ( = 11) cases. Malignant cells were seen in 11.1% of ( = 5) cases. Of the 13 cases that the indication was suspected bladder cancer, only four were positive for malignant cells and one was suspicious on UC. No malignant cell or suspicious cell was seen in any of the UC specimens from patients that had prostate cancer, lower urinary tract outlet obstruction with hematuria due to prostatic enlargement.

CONCLUSION

UC should not be requested for in prostatic diseases since the reports are always negative or at most inflammatory. The department should start using The Paris System of UC reporting to assist the managing physician/surgeon to take the best decision.
