Study summary

Biological behabiour of low grade bladder cancer tumors is well known. They have a very high rate of recurrences during their follow up but very low (less than 1%) risk of progression.

Until now, the gold standard of any bladder recurrence for this patients is performing an immediate transurethral ressection of the tumor.

This surgery has risk of complications and, due to the low risk of these subgroup of tumors, sometimes it becomes an overtreatment for the patients.

This is the reason why new conservative or less invasive surgeries are proposed to follow up and treat these patients.

Study arms

  • No intervention
    Active surveillance

    After a recurrence in patient with previous low grade bladder cancer tumor, strict follow up with cystoscopy and cytology, avoiding immediate surgery

  • Active comparator
    endoscopic fulguration

    After a recurrence in patient with previous low grade bladder cancer tumor, fulguration under local anesthesia and sedation will be performed using a flexible cystoscope and a monopolar electrode

    Procedure: Endoscopic fulguration

Interventions

  • ProcedureEndoscopic fulguration

    already included. WE will use Storz monopolar device for fulguration
