Final answer:
Urethral meatal stenosis is corrected by a procedure called urethroplasty, which provides a more permanent solution to the narrowing by reconstructing or repairing the urethra.
Step-by-step explanation:
Urethral meatal stenosis is corrected by a procedure known as urethroplasty. This surgical technique involves the reconstruction or repair of the urethra to alleviate the narrowing or obstruction, hence restoring normal urinary function. Alternative procedures, like urethrotomy, involve making an incision in the urethra to relieve the stricture, but urethroplasty typically provides a more permanent solution to the problem. Ureteroscopy is a procedure where a scope is passed up through the urethra and bladder into the ureter and is primarily used for diagnosing or treating stones rather than strictures. Lastly, urethrectomy, which is the removal of all or part of the urethra, is not a treatment for stenosis and is typically performed for severe urethral disease or cancer.
