Kimball I. Cystoscopy and ureteroscopy are performed to diagnose and treat lesions of the lower urethra, prostate, and bladder and upper ureter and kidney urinary tracts.
Warmed irrigation fluids are used to improve visualization and to remove blood, tissue, and stone fragments. Because of ionization, they cannot safely be used for procedures involving monopolar electrocautery. However, these solutions can be used with newer, bipolar electrocautery. Sterile water has optimal visibility and is nonconductive. Nonelectrolyte solutions of glycine, sorbitol, and mannitol have good visibility and are nonconductive.
Near isotonicity minimizes hemolysis, although large volume absorption may cause hyponatremia see section 3. Anesthesia a. Placement of a rigid cystoscope particularly in males and distention of the bladder and ureters can be quite stimulating.
Two of these patients returned to theatre because bleeding problems; one, with abnormal renal vasculature, may have had a splenic infarct. Reprints and Permissions. Postoperative ventilation may be needed because of prolonged retraction of the lung that is causing contusion. Systematic review is a research method that pools the results from individual trials and can resolve conflicts in the literature. One of the most serious complications of spinal anesthesia is cardiac arrest [ 17 — 19 ]. Varying dose of Hyperbaric Bupivacaine. The median nerve is susceptible to neuropathy due to excessive stretching as it courses through the antecubital fossa.
Postoperative pain is minimal. If regional anesthesia is used, a T6 level is required for upper tract instrumentation, whereas a T10 level is adequate for lower tract surgery. GA can be effective with short-acting intravenous IV and inhaled anesthetics.
Transient muscle relaxation may be required. Lithotomy position is most common. Transurethral resection of the bladder TURB is performed to diagnose and treat lesions of the bladder anesthetic considerations are similar to TURP—see below. Muscle relaxation should be considered as inadvertent simulation of the obturator nerve, deep to the lateral bladder wall, may result in leg adduction, thus risking damage to the bladder.
This procedure uses a modified cystoscope resectoscope with a wire loop connected to an electrocautery unit for resection of tissue and coagulation of bleeding vessels. During surgery, large prostatic venous sinuses can be opened, which allow irrigant to be absorbed. The quantity of fluid absorbed depends on the following factors: a.
poimiboxmywac.ml Irrigant hydrostatic pressure, proportional to the height of the irrigant above the patient. Surgical technique: duration of exposed sinuses, irrigation flow rate, and cystoscope size. Varying dose of Hyperbaric Bupivacaine.
