Syringocele in adult patient. Case report.

OBJECTIVE: To describe one case of syringocele in an adult patient. METHODS/RESULTS: We report the case of a 26 year old man who presented frequency, hematuria and fever during one year, mictional cystourethrography showed a syringocele. Treatment consisted in endoscopic surgery, with good results in the follow-up. CONCLUSIONS: The syringocele is a relatively infrequent entity, that is necessary to study in a young patient with voiding symptoms, accompanied or not of haematuria and fever. The diagnosis is based on the cystourethrography, and treatment consisted, usually, in endoscopic surgery.

[Metastasis in maxilar sinus as only manifestation of disseminate renal adenocarcinoma]. / Metástasis en seno maxilar como única manifestación de adenocarcinoma renal diseminado.

Paranasal sinuses and nose metastasis are very uncommon. About 50 have been reported. Renal cell carcinoma is the primary neoplasm which most frequently metastasizes in the nasosinusal region, followed by breast and lug. Symptoms are unspecific, but the epistaxis constitutes the most common sign due to the significant vascularizations of the tumor. Prognosis is poor. The survival rate fluctuates between 15-30% at 5 years. Surgery is the elective treatment.

[Intraocular metastatic renal carcinoma presenting as progressive unilateral blindness]. / Carcinoma renal metastásico intraocular. Ceguera unilateral progresiva como forma de presentación.

Clear cell renal carcinoma is the most common histological type, representing 70-80% of all renal carcinomas. Metastases are already present in about 25-30% of patients at the time of diagnosis of renal cell carcinoma. Ocular metastasis is extremely rare.

[Retroperitoneal cystic lymphangioma. A silent disease in adults]. / Linfangioma quístico retroperitoneal. Una patología silente en adultos.

Primary retroperitoneal tumours may arise from different structures as neural, mesodermal, urogenital ridge, or embryonic remnant tissues. Lymphangioma is a rare benign tumour of the lymphatic tissue. They result from a developmental failure of the lymphatic system. Although benign, they can compress and infiltrative vital structures. The size of the lesion is more important than its location to the symptomatology development. Intraabdominal and retroperitoneal lymphangioma are the rarest tumour, specially when occurring in adults. The tumour can occur at any age and most are asymptomatic. Preoperative diagnosis is facilitated by ultrasonography and computed tomography. In order to correctly diagnose of these neoplasms it is essential to carry on ultrasound and CT examination. Treatment of choice is always surgical and a complete extirpation should be performed, unless vital structures were are involved.

[Giant stone in a Bricker urinary diversion. Obstruction uropathy as the presenting form]. / Litiasis gigante en derivación urinaria tipo Bricker. Uropatía obstructiva como forma de presentación.

Bowel is used in urological surgery to replace the bladder, either as a conduit to drain urine to the abdominal wall as a urinary stoma or refashioned to form a substitute bladder. Many factors contribute to stone formation, being urinary stasis, mucus production and bacteriuria the most important. Metabolic changes induced by exposure of segments of the alimentary tract to urine promote struvite, calcium oxalate and calcium phosphate stone formation. Generally, the majority of patients with stones in a urinary diversion can be treated with minimally invasive techniques. Open surgical removal is considered when other modality of treatments cannot be accomplished safely and expeditiously.
