Cystoscopic Suction Diathermy for the Treatment of Superficial Bladder Tumours

Abstract

The treatment of superficial bladder tumours (Ta, T1) is a time-consuming exercise for urological surgeons and patients. A method of treating the tumours, whether primary or recurrent, by endoscopic suction diathermy has been developed. The technique significantly reduces the amount of tumour debris within the bladder during treatment as well as the amount of diathermy employed. By removing the free tumour cells in the irrigation fluid the risk of tumour cell implantation may be kept to a minimum.

Upper Quadrant End Ureterostomy as Urinary Diversion for a Solitary Kidney in a Case of Extensive Urothelial Tumours

“…Patient's anterior abdomen showing the position of the future diathermy damage to the gastrointestinal tract. Direct rigid ureteroscopy in the course of this procedure revealed several tiny upper ureteric tumours which were treated by combined suction and diathermy (Bunce et al, 1991). Histology of these tumours showed pT1 G2 transitional cell carcinoma.…”

The Treatment of Superficial Bladder Tumours under Local Anaesthetic Using Suction Diathermy Electrodes

“…More recently, diathermy of small lesions without anaesthesia through a flexible cystoscope has been used with only mild patient discomfort [5]. Suc tion diathermy electrodes have recently been introduced to treat superficial bladder tumours through a standard cystoscope [6], These electrodes allow for controlled suc tion to be applied to tumours with or without diathermy and have significant advantages over the standard electrosurgical techniques for treating small papillary lesions. The majority of the tumour fronds of superficial tumours are friable enough to be removed by suction alone, dia thermy only needed to free more adherent portions and to treat the tumour base adequately.…”
