Brief Summary

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

En bloc resection of bladder tumors (ERBT) may improve staging quality and perioperative morbidity and influence tumour recurrence

Detailed Description

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

Modern laser technology has led to new alternatives to conventional TURBT (cTURBT). The advocates of ERBT have three goals: to improve resection quality, lower perioperative complication rates, and decrease recurrence rates at resection sites. The present study is the first to compare the results of laser and electric en bloc resection of bladder cancer with respect to the aforementioned goals.

the investigators aim to compare the clinical outcome in the form of safety and efficacy between Holmium and bipolar transurethral en bloc resection of urinary bladder tumors.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

After obtaining informed consent, patients will be randomized with a 1:1 ratio using sealed envelopes that will be prepared by the department's ethical committee into 2 groups, group 1 represent the Holmium en bloc resection procedure while group 2 represents bipolar en bloc resection. Patients will be blinded to the type of intervention as well as the data collector and the statistician.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Holmium en bloc resection

Holmium en bloc resection procedure will be done under either general or spinal anesthesia, using a Holmium laser device (Cyber Ho, Quanta device, Milano, Italy). We will use a 30-40-watt power, 1-2 joules and 20-30 MHz frequency

Group Type EXPERIMENTAL

Holmium versus Bipolar en bloc transurethral resection

Intervention Type PROCEDURE

After obtaining informed consent, patients will be randomized with a 1:1 ratio using sealed envelopes that will be prepared by the department's ethical committee into 2 groups, group 1 represent the Holmium en bloc resection procedure while group 2 represents bipolar en bloc resection. Patients will be blinded to the type of intervention as well as the data collector and the statistician.

Intervention: all procedures will be done by an expert surgeon who performed over 50 cases of en bloc urinary bladder tumor resection with each energy source. In group A, Holmium en bloc resection procedure will be done under either general or spinal anesthesia, using a Holmium laser device (Cyber Ho, Quanta device, Milano, Italy). We will use a 30-40-watt power, 1-2 joules and 20-30 MHz frequency for Group A and bipolar en bloc resection for Group B. A 550 nm flexible laser fiber will be used in group A and a bipolar resection loop for group B.

Inclusion Criteria

* Adult patients of both sexes presented with urinary bladder tumor aiming for complete resection as diagnosed by Ultrasound with or without CT prior histopathological assessment.

Exclusion Criteria

* Patients with signs of extravesical tumor extension where complete resection will not beneficial or unable to proceed to complete resection due to huge tumor burden either huge single tumor more than 5 cm or multiple tumors that are not candidate for complete resection.
