AMBULANT FLEXIBLE CYSTOSCOPY FOR FOLLOW-UP OF Ta-TI UROTHELIAL CARCINOMA OF THE URINARY BLADDER: PAIN PERCEPTION AND COST EFFECTIVE.

Ambulant flexible cystoscopy is the standard procedure in the urological practice for follow-up of Ta-T1 urothelial carcinoma (UC) due to its ability to survey the bladder for a variety of indications. It is the principal means of diagnosis and surveillance of bladder tumors. The follow-up of patients treated for Ta-T1 UC is of great importance because of the high incidence of recurrence and progression of the disease, whereby patients with Ta-T1 UC undergo cystoscopy every three months. The aim of this study to evaluate the procedure of ambulant flexible cystoscopy in proper diagnostic follow-up of Ta-T1 UC, patient's acceptance in regard to pain tolerance, non-hospital stay and expenses. Twenty one patients (18 male and 3 female) were diagnosed before as Ta-T1 UC by rigid cystoscopy and transuretheral resection of bladder (TURB) lesion scheduled for follow up by flexible cystoscopy under local anesthesia using 20 ml 2% lidocain gel on an ambulatory bases. Comparison was done using a cohort of 32 patients who underwent the procedure of follow-up of Ta-T1 cystoscopy and TURB using rigid cystoscopy and resectoscope. Seventeen patients 80.9% (16 male and 2 female) proved to be bladder free from recurrent lesion, 4 patients {19.1 %} (3 males and one female) which revealed recurrent lesions in spite of that the urinary bladder was free in pelvic ultrasonography. Cold cup biopsy from the lesions sent for histopathological examination which revealed recurrence of the tumor in 3 patients (two patients with Ta and one patient T1. TURB was done to have complete resection in 4 patients, the histopathological examination revealed ulcerating mucosa and free lamina propria in 3 specimens, and T2 in the fourth specimen. Comparison between the 2 groups revealed more patient's acceptance for the flexible cystoscopy group as regard pain tolerance, non-hospital stay and expenses. Ambulatory flexible cystoscopy with 20 ml of 2% lidocaine gel anesthesia is tolerated well by patients, with advantage of no hospital stay in the regular follow up of Ta-T1 tumors, pain perception was accepted by all patient provided delayed cystoscopy after lidocaine-gel instillation.
