Patients and Methods: This was a retrospective study carried out from 2015 to 2019 on 32 patients with bladder tumors that were managed at the Centre medico-chirugical d’urologie in Douala, Cameroon. The relevant data were obtained from patients’ clinical records. Results: A total of 32 patients (25 men and 7 women) aged 29 - 75 years were included in this study. The mean age of the study participants was 58.63 ± 11.00 years. Among our study participants, there were 10 smokers (31.25%). Eight (25%) of them had occupational exposure while 2 (6.25%) had residential exposure to bladder cancer. Thirty (93.75%) presented with hematuria, 2 (6.25%) presented with recurrent urinary tract infections, and 1 (3.13%) presented with acute urinary colic. Nineteen (59.38%) of them were anemic, with 4 (12.5%) requiring blood transfusions. Twenty-seven (84.38%) of them had pedunculated tumors while 5 (15.62%) had sessile tumors. The tumor diameters ranged from 1 cm to 5 cm, with a mean diameter of 2.75 ± 1.22 cm. Complete resection was performed in 27 (84.38%) participants while partial resection was performed in 5 (15.62%) patients. The early single instillation of intravesical chemotherapy with mitomycin was performed in 8 (25%) patients. Only one (3.13%) patient had a postoperative complication, and seven (21.88%) patients experienced tumor recurrence and underwent a second TURBT. Two (6.25%) of the 32 patients died and 30 (93.75%) survived. Conclusion: TURBT is the gold standard method of managing bladder tumors. This procedure is at the same time diagnostic and therapeutic for tumors that do not invade the walls of the urinary bladder.展开更多
