Double urethra is a very rare congenital disease. We observed and treated two cases of incomplete double urethra, one had ventral opening and stones, the other had subscrotal opening. And report with review of literatures.

This is a rare case of a mucosal melanoma, located in the urethra of a 59-year-old male. Malignant melanomas of the genitourinary tract are rare, representing <1% of malignancies in the genitourinary tract, and <0.1% of all melanomas. In the male genitourinary tract, the most affected sites are the glans penis and the distal urethra in the fossa navicularis. Urethral melanomas comprise 4% of all urethral cancers.

Graft substances such as skin, bladder and buccal mucosa have been used for urethral replacement when local epithelial tissue is not available. However, these subtances have been associated with meatal prolapse, stricture and fistula formation. We tried tunica vaginalis as a urethral graft in rabbitsA graft of tunica vaginalis was placed in the excised portion of the urethra in five experimental rabbits. After 6 weeks retrograde urethrograms revealed no strictures and a fistula formation in one rabbit. The histopathologic examination revealed that the tunica vaginalis was covered by the transitional epithelium of the urethra. The tunica vaginalis could be used as a urethral graft in animals with a fistula formation as a complication. (Author)

Leiomyoma of the female urethra is a very rare condition. A case of the leiomyoma arised from paraurethral area, between the urethra and vaginal wall in thirty seven-year-old female is presented. The weight of mass was 50g and 7X4x5cm. in size. That was enucleated surgically and confirmed as a leiomyoma histologically.

Duplication of the urethra is a rare congenital anomaly. It may be complete or partial, and each form has its distinctive anomaly, symptom complex, and treatment. Retrograde urethrography and voiding cystography were necessary to define the anatomy of duplication completely and accurately in each patient. I reported a case of complete patent duplication of the urethra in 34-year old male with the brief review of literature.

Leiomyoma of the female urethra is a rare entity. We experienced a case of leiomyoma in the female urethra recently. Forty-one-year-old woman admitted to the hospital with the chief complaint of a painless, protruded large mass outside the vaginal introitus. The mass was excised surgically and confirmed as a leiomyoma pathologically.
