Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study compare the efficacy of conventional photodynamic (PDD) guided transurethral bladder tumor resection in the operating theatre with outpatient PDD guided laser destruction of bladder tumors through flexible cystoscopes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A prospective randomized two-part clinical trial comprising patients with recurrent pTa low grade bladder tumors.

Study objectives and purpose:

* 1st Objective: To evaluate whether small pTa bladder tumours can be removed with diode laser in an outpatient department with similar efficacy as by TUR-BT resection in the operating theatre.
* 2nd Objective: To evaluate the patients experience of symptoms during laser treatment in the outpatient department (OPD) using quality of life (QOL) questionnaires (symptom evaluation) and Visual Analog Scale Score (pain evaluation).
* 3rd Objective: To evaluate whether patients prefer standard transurethral bladder tumor resection (TUR-BT) in the operating theatre (OT) or laser treatment in the OPD.
* 4th Objective: To evaluate the safety after laser treatment in the OPD.

Efficacy:

* 1st Endpoint: Proportion of patients with no tumor tissue in the bladder after 4 months and 12 months.
* 2nd Endpoint: Visual Analog Scale Score (pain evaluation) in patients having tumor removed by laser in the OPD.

General urinary problems and QOL one week after the laser treatment. The Danish validated questionnaire (QLQ- BLS24) from EORTC will be used.

* 3rd Endpoint: Patients preference for either OPD laser treatment procedure or TUR-BT in the OT as inpatient procedure.
* 4th Endpoint: Character and severity of adverse events in relation to the outpatient treatment.
