The patient was 17 years old and came to our hospital one month ago because of urethral fistula. Five years ago, the patient underwent urethroplasty for hypospadias, after which he developed urethral fistula, and had his urethral fistula repaired twice in provincial hospitals, which was unsuccessful and brought great pressure to the patient and his family. After discussion in the department, it was decided to perform the third urethral fistula repair. Considering the patient’s history of multiple surgeries, the local scar is serious, poor blood circulation, easy to re-operation failure, and the patient is different from children, the urethral secretion is more, which also increases the risk of surgical failure. During the operation, the scar was fully excised, sutured finely, and the urethra was made tubeless at the risk of urethral stenosis. The patient recovered well and was discharged from the hospital. During the same period, the department performed posterior urethral anastomosis + partial pubic bone chiseling for a patient with complicated urethral stricture. This patient had pelvic fracture and posterior urethral stenosis due to trauma, and had undergone pelvic fracture fixation and posterior urethral anastomosis in a local hospital, and still had difficulty in urination after the operation. Firstly, ultrasound-guided suprapubic cystocentesis was given to control the urinary tract infection. Later, urethrography and soft microscopy were performed, which confirmed the posterior urethral stenosis with pseudotunnel formation. After discussion in the department, Associate Professor Zhang Dongqing and Attending Physician Zhou Changjang decided to perform posterior urethral anastomosis again. During the operation, the proximal end of the urethral stenosis was repeatedly confirmed by soft microscope through the vesicostomy port to avoid entering the pseudotunnel. The urethral stenosis section was long, about 3cm, with severe scarring, which made the anastomosis difficult, so the patient was given a thorough scar removal, attention to the protection of the rectum, and chiseling part of the pubic bone to perform a tension-free anastomosis of the urethra. After the operation, the patient recovered well and urinated freely. Common urethral diseases include urethral stricture, hypospadias, and urethral fistula, etc., which have been a difficult problem for urologists because of the high failure rate of surgery and many complications.
