## Abstract

The present invention describes a method for performing a prostate surgical treatment, said method comprising: arranging a catheter 1 inside of a urethra of a patient and anchored against the bladder neck of the patient subsequent to the filling of the balloon stopper unit 5 with a fluid when the balloon stopper unit 5 is arranged inside of the bladder of a patient; said method also comprising injecting at least one anesthetic agent and adrenaline or injecting botulinum toxin (Botox) and/or penicillin to the prostate via the injection tube 9 and the hollow tip 10 at an intended position of the prostate. Moreover, the present invention also refers to a kit comprising a catheter 1 according to the present invention and one or more syringe(s) 1000 containing adrenaline and at least one anesthetic agent and/or at least a syringe 1000 or vial containing botulinum toxin (Botox) and/or penicillin.

## Claims

### Claim 1

A method for performing a prostate surgical treatment, said method comprising:
arranging a catheter comprising:
an introduction unit with a top, said introduction unit also comprising a drainage lumen hole for drainage of a urinary bladder;
a balloon stopper unit in connection with and thus possible to fill via a balloon inflation connection and balloon filling tube arranged inside of the introduction unit, wherein filling of the balloon stopper unit with a fluid is intended when the balloon stopper unit is arranged inside of the bladder of a patient to provide for a stopper function of the balloon stopper unit against a bladder neck of the patient;
an injection connection connected to an injection tube arranged inside of the introduction unit, which injection tube extends in a hollow tip arranged to be provided to extend from the introduction unit; and
a drainage outlet;
inside of a urethra of a patient and anchored against the bladder neck of the patient subsequent to the filling of the balloon stopper unit with the fluid when the balloon stopper unit is arranged inside of the bladder of a patient,
injecting at least one anesthetic agent and adrenaline to the prostate via the injection tube and the hollow tip at an intended position of the prostate; and
changing the position of the hollow tip in the prostate to enable at least injection of said at least one anesthetic agent at different positions in the prostate; and
injecting both at least one anesthetic agent and adrenaline to one first half of the prostate, then removing the catheter from the patient and performing trimming of that first half of the prostate in a transurethral resection of the prostate (TURP) surgical treatment, then inserting the catheter again into the patient and injecting both at least one anesthetic agent and adrenaline to a second half of the prostate, then removing the catheter from the patient again and performing trimming of that second half of the prostate.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising injecting at least one anesthetic agent to the prostate via the hollow tip and injecting adrenaline to the prostate via the hollow tip during at least a first phase of the method, wherein at least the injecting of adrenaline to the prostate is performed sequentially.

### Claim 3 (depends on 2)

The method according to claim 2, further comprising injecting both at least one anesthetic agent and adrenaline, sequentially to different parts of the prostate.

### Claim 4 (depends on 3)

The method according to claim 3, further comprising injecting both at least one anesthetic agent and adrenaline sequentially to at least four different squares of the prostate.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising changing the position of the hollow tip in the prostate to enable injection of at least one anesthetic agent and adrenaline at different positions in the prostate.

### Claim 6 (depends on 1)

The method according to claim 1, further comprising injecting both at least one anesthetic agent and adrenaline to one part of the prostate, then supplying heat to the surface of the prostate at a corresponding position to that part of the prostate, then injecting both at least one anesthetic agent and adrenaline to another part of the prostate and then supplying heat to the surface of the prostate at a corresponding position to that other part of the prostate.

### Claim 7 (depends on 2)

The method according to claim 2, further comprising a sequence of injecting both at least one anesthetic agent and adrenaline to a volume of the prostate and then performing trimming in a transurethral resection of the prostate (TURP) surgical treatment or a heat treatment of a corresponding surface of the prostate within a time frame of maximum 25 minutes, and then performing yet another similar sequence to another volume of the prostate.

### Claim 8 (depends on 1)

The method according to claim 1, wherein the method involves means for locating the hollow tip.

### Claim 9 (depends on 8)

The method according to claim 8, wherein said means for locating is an external means.

### Claim 10 (depends on 1)

The method according to claim 1, further comprising injecting one or more cytostatic agents to the prostate.

### Claim 11 (depends on 1)

The method according to claim 1, further comprising injecting at least one of botulinum toxin (Botox) or at least one antibiotic agent to the prostate.

### Claim 12 (depends on 11)

The method according to claim 11, wherein injecting at least one of botulinum toxin (Botox) or at least one antibiotic agent to the prostate is performed as a treatment of prostatitis.

### Claim 13 (depends on 11)

The method according to claim 11, wherein said at least one antibiotic agent is penicillin.
