Ureteral stent insertion is a common procedure in the urologic field. Although the migration of ureteral stent is uncommon, it can be serious complication. We report the migration of Thermo-Expandable Stent (Memokath) from upper ureter to renal pelvis, and which was managed by surgical removal after failed rigid and flexible ureteroscopic manipulation.

Spontaneous intracranial hypotension is a syndrome caused by cerebrospinal fluid (CSF) leakage from the spinal dural sac. The most common symptom is a postural headache and other clinical symptoms may include nausea, vomiting, photophobia, diplopia, dizziness, and tinnitus. Usually, conservative treatments like hydration, bed rest, and administration of caffeine are recommended first, but epidural blood patch is regarded as the mainstay of treatment in the patients who do not respond to conservative therapy. Epidural blood patch was known that it provides the tamponade and seal of dural sac when performed at the leak site. Our patient was suspected the CSF leakage at cervicothoracic junction, but epidural blood patch was performed in lumbar level and the headache of patient was managed successfully for at least 1 year.

The classic presentation of renal cell carcinoma (pain, hematuria, and flank mass) occurs in a minority of patients and often is indicative of advanced disease. Common sites of metastatic renal cell carcinoma are lung, soft tissues, bone, and liver. Paranasal sinus is an unusual site for metastasis of renal cell carcinoma. One 73-year-old male presented to Soonchunhyang University Seoul Hospital with melena. Renal cell carcinoma with metastasis to duodenum was diagnosed by computed tomography (CT). He underwent right radical nephrectomy and Whipple's operation. Positron emission tomography/CT was performed postoperatively, and then metastasis to maxillary sinus was found by accident. He was treated with molecular targeted therapy (pazopanib hydrochloride 800 mg).

Congenital hyperinsulinism is the most frequent cause of severe, persistent hypoglycemia in infancy and childhood. It is caused by an inappropriate insulin secretion from the pancreatic beta-cells secondary to various genetic disorders. Recognition of this entity becomes important due to the fact that hypoglycemia is very severe and frequent and that it may lead to severe neurological damage in the infant manifesting as mental or psychomotor retardation or even a life-threatening events if not recognized and treated effectively in time. Hypoglycemias can be detected by seizures, fainting, or any other neurological symptoms in the neonatal period or later, usually within the first two years of life. Hypoglycemias must be rapidly and intensively treated to prevent severe and irreversible brain damages. Next, a treatment to prevent the recurrence of hypoglycemia must be set, which may include frequent and glucose-enriched feeding, diazoxide and octreotide. We report a case of congenital hyperinsulinemia in a 2 months old infant presenting as atonic seizure which has been treated with diazoxide.

Severe adenovirus pneumonia that causes acute respiratory failure can occur in infants, children, and immunocompromised patients. However, severe adenovirus pneumonia is rare in adults with a normal immune system. Adenovirus pneumonia may progress to acute respiratory failure in a few hours or a few days, and its clinical course cannot be predicted. In addition, the mortality rate is very high (range, 50% to 66%). However, the optimal treatment of adenovirus pneumonia has not been established. Herein, we report the successful treatment of acute respiratory failure due to adenovirus pneumonia with extracorporeal membrane oxygenation.

We presented a case of a 46-year-old man who attended the emergency department with right flank pain. Abdominal computed tomography showed dilated renal pelvis, ureter and distended bladder. Fluid collection was seen in retroperitoneal space and pelvic cavity. He had renal insufficiency. When a urethral catheter was inserted, 1,200 mL urine was drained. He was diagnosed with schizophrenia more than 20 years prior, and had been taking anti-psychotics. He had been living in a sanatorium. He had nocturnal enuresis and had worn an incontinence pad nightly for the last 10 years. His fluid consumption was 10 L/day. After placement of an indwelling urethral catheter for relieving voiding problems and restriction of fluid intake, fluid collection in retroperitoneal spaces and pelvic cavity was removed and renal insufficiency was recovered. After training of self-clean intermittent catheterization, he was discharged.

The synthetic, tension-free midurethral sling procedure using transobturator tape (TOT) was introduced in 2001. Since then, it has become a mainstream modality in patients with stress urinary incontinence. But, it has been reported to produce many complications such as mesh erosion, hematoma formation, and abscess. We experienced a case of abscess formation in the peritoneal cavity and left internal obturator muscle seven days after the TOT sling procedure, for which we performed a complete removal of mesh and a percutaneous drainage of the peritoneal abscess using 10.2-F drain-fix at the department of interventional radiology. To our knowledge, our case is one of the serious complications of the TOT procedure. Here, we report our case with a review of literatures.

We report a case of a 41-year-old man undergoing hemodialysis who presented with a sudden fever and dyspnea. He developed a severe pericardial effusion due to methicillin-resistant Staphylococcus aureus, which was identified in both blood and pericardial fluid cultures. He was successfully treated with intravenous vancomycin for 6 weeks. Although such cases are very rare in Korea, the current case describes a primary purulent pericarditis without any other potential infectious foci.

Vulvar carcinoma is a rare disease that accounts for 5% of gynecologic cancers. Sarcomas of the vulva are extremely rare, and account for only 1% to 3% of all vulvar malignancies. We report of a case of a 26 years woman with a vulva mass. Excision was done and histopathologic result showed rhabdomyosarcoma.
