Objective To correlate the cystoscopic appearance of recurrent papillary bladder tumours with the histology after transurethral resection, and thus ascertain whether cystoscopy can reliably identify low‐grade, noninvasive papillary tumours suitable for outpatient fulguration. Patients and methods In all, 150 recurrent papillary tumours of the bladder identified at outpatient flexible cystoscopy were classified as either low‐grade and noninvasive (TaG1), high‐grade and noninvasive (TaG3), or invasive (T1G3) tumours, and correlated with urine cytology and histology of tumour stage and tumour grade after transurethral resection. Results Cystoscopy classified 84 of the 150 papillary tumours as TaG1 and 66 as either TaG3 or T1G3. Cystoscopy correctly predicted the histology of 78 of 84 (93%) TaG1 tumours, 71 of 72 (98%) TaG1 tumours associated with a negative urine cytology, and 92% of TaG3 or T1G3 tumours. Conclusions A skilled urologist can identify noninvasive, low‐grade recurrent papillary bladder tumours on follow‐up cystoscopy that do not require biopsy and that may be treated by outpatient fulguration alone.
