  • Dysuria


Many urological conditions are diagnosed and treated with the use of endourology procedures. Unfortunately, dysuria is a common patient complaint following these procedures. Intraurethral lidocaine instillation is regularly used prior to office-based endourology procedures to alleviate dysuria, as well as, discomfort during the procedure.. Studies have confirmed that office-based procedures using intraurethral lidocaine have resulted in less patient reported dysuria. Many endourology procedures are done under general anesthesia such as urinary stone treatments or resection of bladder tumors. There is a paucity of data regarding the use of intraurethral lidocaine at the conclusion of these procedures evaluating patient reported dysuria. We have designed a prospective, randomized, placebo controlled trial to evaluate the role of intraurethral lidocaine instillation following endourology procedures in the anesthetized patient.


Inclusion Criteria: Adult patients, age 18 and older scheduled to undergo endourologic procedure to include ureteroscopy, rigid diagnostic cystoscopy, bladder biopsy, laser lithotripsy, cystolithalopaxy, and transurethral resection of bladder tumor in the operating room under general anesthesia. Exclusion Criteria: active urinary tract infection, current dysuria symptoms, pregnant females, urethral stricture disease, indwelling foley catheter, and history of pelvic radiation
