Urethral stricture after suburethral cleavage is a common complication, and the urethral stricture mostly occurs at the urethral meatus of the glans section and the urethral anastomotic stoma at the near end, and the urethral anastomotic stoma stricture is mainly caused by poor supply of formed urethral blood, and the anastomotic stoma is not subjected to inclined anastomosis and the like. The cicatrix is the most serious period about 1 month after the suburethral fissure operation, which can cause transient urethral stricture, and secondary urethral diverticulum is caused when the cicatrix is serious, and the urethral diverticulum is often accumulated with urinary calculus and is easy to cause urinary tract infection. For those with significant urethral strictures, early stage strictures within 3 months of surgery may be useful for urethral dilation. If the patient is not effective or serious, the urethral stricture is cut or the urethral fistulization is cut off at the stricture part, and the obstruction caused by the urethral stricture is relieved for 6 months, and then the urethral diverticulum is cut off for urethral repair operation.
The urethral dilatation is a conservative treatment method for treating urethral stricture after the urethral lower laceration operation, and the treatment is effective to relieve urethral stricture and prevent urethral diverticulum and urethral calculus from forming and urethral infection. Avoiding secondary operation to increase the pain of the child patient and aggravating the family economic burden of the child patient.
Existing urethral dilators are as follows: 02288382.7, name of utility model: the urethral dilator is characterized in that a filiform probe is designed into a soft hollow catheter, and a hard catheter core is arranged in the inner cavity of the hollow catheter according to the requirement. However, the utility model lacks the function of measuring the length of the urethral stricture, the diameter of the stricture and the distance between the stricture and the external orifice of the urethra, and also lacks the function of taking materials from the inflammatory secretion of the urethra and stones.
