[A Case of Metachronous Rupture of Right Testis and Right Epididymis].

The patient was a 15-year-old male. Four months prior to his visit to our department, he was hit in the right scrotum by a baseball, which caused right scrotal swelling and pain. He visited a urologist who prescribed analgesics. During follow up observation, right scrotal hydrocele appeared and a puncture procedure was performed two times. Four months later, while climbing a rope for strength training, his scrotum became entangled by the rope. He immediately felt right scrotal pain and visited a urologist. Two days later, he was referred to our department for a thorough examination. Scrotum ultrasound revealed right scrotal hydroceles and swollen right cauda epididymis. The patient was treated conservatively with pain control. The next day, the pain did not improve, and surgery was decided since testicular rupture could not be completely ruled out. Surgery was performed on the third day. The caudal portion of the right epididymis was injured approximately 2cm, the tunica albuginea had been ruptured and the testicular parenchyma had escaped. The surface of the testicular parenchyma was covered with a thin film, suggesting that 4 months had elapsed since the tunica albuginea injury. The injured area of the epididymis tail was sutured. Subsequently, we removed the remaining testicular parenchyma and restored the tunica albuginea. Twelve months postoperatively, right hydrocele and testicular atrophy were not observed.
