[The influence of combined surgery for bladder cancer and bladder-neck obstruction on the recurrence of bladder cancer].
A comparative retrospective study with follow-up survey was performed on 75 male bladder cancer patients, in order to investigate the relation between bladder carcinoma and bladder-neck obstruction, and effect of combined surgical treatment for both lesion on the recurrence of bladder cancer. All the bladder cancers were confirmed by cystoscopy and histopathological examination. The pathological findings included: 69 cases of transitional cell carcinoma, 5 cases of squamous cell carcinoma and 1 case of adenocarcinoma. All patients were treated by partial cystectomy and followed-up by cystoscopy and urine exfoliative cytologic examination. Thirty patients (group I) who had bladder cancer and bladder-neck obstruction received simultaneous partial cystectomy and cystauchenotomy were compared to 21 patients (group II) who had both lesions but received partial cystectomy only, and to 24 patients (group III) who had bladder cancer only and underwent partial cystectomy. Evaluation of recurrence of bladder cancer in each group showed that recurrence occurred in 6 patients (20%) in group I, 10 patients (47.1%) in group II, and 4 patients (16.6%) in group III. The data showed that partial cystectomy combined with cystauchenotomy in patients with bladder cancer accompanied by bladder-neck obstruction significantly decreased the postoperative recurrence of tumor in comparison with the group treated by partial cystectomy alone. It is suggested that the presence of bladder-neck obstruction may exert some effects on the genesis and postoperative recurrence of bladder cancer.
