Objective: To highlight the pattern of patients with transitional cell carcinoma of the
urinary bladder with regards to age, sex, ethnic origin and histopathological classification.
Design: A ten year retrospective study.
Setting: Kenyatta National Hospital, Nairobi, Kenya.
Subjects: Fifty two patients who presented at Kenyatta National Hospital over the ten
year period with histologically proven transitional cell carcinoma of the urinary bladder.
There were 41 males and 11 females aged 27 to 84 years. The mean age was 57 years.
Results: The peak incidence was in the 60-69 years age group. The male to female ratio
was 4:1. The regional (provincial) distribution revealed Central and Eastern had 77%,
Rift valley had 6%, Nairobi, North Eastern, Western and Coast provinces had 2% each.
In the ethnic distribution; Kikuyus, Kambas and Merus were 77% while others were
17.3%. Transitional cell carcinoma was found in 67% of the patients, 60% had advanced
disease. Twenty nine percent were smokers while 25% consumed alcohol. The main
occupation was farming in 65%. The most Common clinical presentations were
haematuria 98% and lower abdominal pains in 71%. A total of 99,028 patients were
admitted to the surgical wards,transitional cell carcinoma patients represented only
0.6%.
Conclusion: Transitional cell carcinoma is a rare disease. At Kenyatta National Hospital
it only represented 0.6% of all surgical admissions during the study period. It accounted
for 67% of all bladder tumours an increase in incidence compared to previous studies.
It is common in males more than females, with a peak in the seventh decade. Majority
of the patients were from central Kenya. Alcohol, smoking and farming were the most
important risk factors. Haematuria was the most important presenting clinical feature.
Poor record keeping may have contributed to the low number of patients enrolled into
the study. There is need for a thorough prospective study to find out the actual
prevalence of bladder tumours.
