Urethral stent pipe used after hypospadias operation

Abstract

The invention discloses a urethral stent pipe used after a hypospadias operation. The urethral stent pipe includes an inner pipe, one end of the inner pipe is placed into the bladder of a child patient, the outer edge of the inner pipe is sleeved with a sleeve pipe which indwells in the urethra of the penis of the child patient after the inner pipe is removed, and several connection points are arranged between the inner pipe and the sleeve pipe. Based on this, the urethral stent pipe can pass through the full length of the urethra of the child patient under an anesthesia condition in the hypospadias operation simply by directly connecting the sleeve pipe with the glans penis of the child patient, one end of the stent pipe is placed in the bladder, the other end of the stent pipe is connected with an urine bag and retained, after the operation, the connection points are cut off at the later stage of wound recovery, the inner pipe is pulled out, only the sleeve pipe is retained at the urethra of the penis of the child patient, the situation is avoided that the urethral stent pipe and the glans penis needs to be connected after disconnection, and the pain of the child patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a urethral stent used after hypospadias surgery. Background technique [0002] Hypospadias is a common urinary system deformity in children, and its typical features are abnormal position of urethral opening, curvature of penis and abnormal distribution of foreskin. Almost all children with moderate to severe hypospadias require surgery. The key to the operation is to reconstruct a section of the urethra using the remaining urethral plate of the child. [0003] In the early stage of wound recovery after hypospadias surgery (about 7 to 10 days after surgery), it is necessary to indwell a full-length urethral stent in the urethra of the child. The primary purpose is to drain urine from the bladder and avoid urinary retention in the child (ie bladder Second, a large amount of urine is directly drained into the urine bag through the urethral stent, across the reconstructed ...
