4.4 POTENTIAL COMPLICATIONS AND RISKS
The same complications and risks that exist for conventional or traditional
surgery exist for laser surgery. These include, but are not limited to, the
following:
Pain: Short-lived pain may occur immediately following endoscopic/
cystoscopic laser therapy and may persist for as long as 48 hours.
Fever and Leukocytosis: Immediately after laser therapy, the patient may
experience fever and leukocytosis, which are commonly associated with
tissue destruction. These generally resolve without treatment. Cultures may
be indicated to exclude the possibility of infection.
Bleeding: Patients may experience bleeding at the site of the laser therapy
during or after laser therapy. Post-treatment hemoglobin and hematocrit are
recommended to assess the severity of the bleeding.
Sepsis: Laser-ablated tissue may become infected after therapy. If a
question of sepsis exists, a culture should be taken and other appropriate
evaluations made.
Perforation: Perforation can occur as a result of excessive exposure to laser
radiation. Perforation can also occur from tumor erosion, or as a result of
any endoscopic/cystoscopic procedure. To clinically diagnose perforations,
patients must be closely monitored post-operatively through physical
assessment of clinical symptoms, hematology studies as deemed
appropriate, and radiography.
Other complications may include:
• Allergic reaction to
medication
• Ulceration
• Edema
• Chills
• Urethral stricture
• Delay in healing
• Sloughing
• Bladder neck
contracture
• Epididymitis
