An unusual cause of painful ejaculation in a young patient: Zinner syndrome.

Introduction: and importance: Zinner syndrome is a rare congenital malformation of the seminal vesicles and the homolateral upper urinary tract. While the majority of patients remain asymptomatic and are discovered incidentally, others present symptoms such as micturition or ejaculatory difficulties, or pain. We report a case of Zinner syndrome in a 32-year-old patient with painful ejaculation and discuss the diagnosis and treatment difficulties. Case presentation: A 32-year-old married patient was consulted for pelvic pain associated with painful ejaculation that had been evolving for six months. The clinical examination was normal. Routine laboratory studies of blood and urine were normal. The patient was explored by ultrasound which showed the absence of the right kidney and the presence of a 7 cm right lateral prostatic cystic mass. On MRI, the right kidney was not visualized. Multiple cysts were seen in the right seminal vesicle. Surgical excision of the cyst by laparotomy was performed. The patient had an uneventful recovery and was discharged on the third postoperative day. Clinical discussion: Congenital malformations of the seminal vesicles are often associated with those of the ipsilateral upper urinary tract, as the ureteral and seminal vesicle buds originate from the mesonephric duct. The syndrome often occurs in the second and third decades of life, especially after the onset of sexual activity. The most common symptoms were dysuria, perineal pain, epididymitis, and painful ejaculation. Diagnostic modalities include ultrasound, MRI, and cystoscopy. In patients with symptoms, the therapeutic management of the cyst includes ultrasound-guided aspiration and laparoscopic or open surgical excision. Conclusion: Seminal vesicle cysts associated with homolateral renal agenesis or hypoplasia are a rare urologic anomaly. The treatment depends on the patient's symptoms. surgical excision of seminal vesicle cysts may be needed for large cysts causing obstructive symptoms.
