A prospective study was performed radiologically to how the incidence and the degree of vesicoureteral reflux in patients with double-J stent. In this study, involved were 52 renal units of 50 patients without vesicoureteral reflux before double-J stent insertion. Voiding cystourethrography was done a week and four weeks after the stent insertion. In patients with vesicoureteral reflux caused by the stent insertion,voiding cystourethrography was repeated 3days after the stent removal to how the persistence of the reflux. Vesicoureteral reflux occurred in 26 of 52 renal units (50%) one week after the stent insertion. The reflux was grade I/II in one renal unit (4%), grade II or III/III in 25 renal units (96%) according to padding system defined arbitrarily by us. The reflux persisted until 4 weeks after the stent insertion in 25 renal units except a renal unit. In 60 or more-year-old male patients, 10 of 12 renal units (83%) showed the reflux, contrast to 5 of 14 renal units (36%) in the remained male patients (p=0.01). There was no difference in the incidence of the reflux by size of the stent, age, sex, and underlying disease. The reflux in stented state disappeared in all the patients after the stent removal. From these we concluded as follows. Vesicoureteral reflux occurred in 50 percent of renal units in patients with double-J stent, and the grade of the reflux was high. It was more common in aged male patients,which suggested close relation between the occurrence of the reflux and the intravesical pressure on voiding in stented patients. After the stent removal the reflux disappeared. Therefore long term indwelling of the stent seemed to have no harmful effect on antireflux function of vesicoureteral unit.

Stone in the enlarged prostatic utricle is relatively rare and usually secondary to cystic dilatation of the utricle. Irritative lower urinary tract symptoms are the most common presenting complaint. Recently we experienced a enlarged prostatic utricle containing multiple stone and reviewed literature briefly.

A 28-year-old man presented with ataxic gait, left side hearing loss and vertigo, symptoms which had first appeared four months previously. MRI showed a 3X4cm mass in the left cerebellopontine angle. The tumor was totally removed via the suboccipital route; During removal, the distal part of the nerve root from which the tumor arose was stimulated and confirmed to be a spinal accessory nerve. Immediately after surgery, the patient's hearing returned and the other symptoms improved rapidly. Histologic examination showed that the tumor was a schwannoma.

PURPOSE: Several published policy statements have warned against the risks associated with trampoline use and recommended safety guidelines. However, few studies have focused on trampoline-related injuries in Korea. This study aimed to assess the incidence and characteristics of pediatric trampoline-related injuries presented to Ulsan University Hospital. METHODS: We retrospectively reviewed the medical records of children aged <16 years with trampoline-related injuries who visited our Emergency Department between 2008 and 2017. RESULTS: Over the 10-year period, 178 trampoline-related injuries were reported, which represented a significant increase (P=0.016). Most (87.6%) of the injuries occurred during the last 5 study years, and a rapid increase in injuries was observed in children aged <6 years. Lower extremity injuries (62.4%) were the most common, followed by injuries of the upper extremities, head and face, and trunk, including injuries to the neck and spine. Sixty-seven children (37.6%) had fractures, and proximal tibia fractures were the most common. Fractures were significantly more common in younger children (<6 years old) than in older children (P=0.026). CONCLUSION: In Korea, the mechanism of trampoline injury is similar to that of injuries incurred in indoor trampoline parks but is characterized by smaller spaces and multiple users. Trampoline use and the incidence of trampoline-related injuries in children aged <6 years are increasing rapidly. Prohibiting the use of trampolines for children aged <6 years, restricting simultaneous use by multiple children, and ensuring adult supervision should be strictly emphasized. Public awareness and policy guidelines are needed to reduce the incidence of trampoline-related injuries.

We reviewed 15 cases of necrotizing fascitis of the male genitalia. The clinical courses could be divided into two different types. In about one half of the patients the symptoms and signs progressed slowly within 122 weeks and in the remained they progressed rapidly. In the former, the prodromal signs were noted, usually low abdominal and inguinal pain. In 8 of fifteen patients, the locations of infectious focus were difficult to determine. The diagnosis were made after the development of scrotal necrosis in all of the cases. There were no differences in the causative pathogens comparing to 1hose of previous reports. The common underlying diseases were liver cirrhosis and diabetes. Hypoalbuminemia and leukocytosis were found in all. Of course, the strategy of treatment is same between two types, we would like to propose to use the term Fourier`s gangrene, a specific form of necrotizing fascitis, only to whose clinical course in acute and the location of primary infecious foci are obscure.

The spontaneous axon regeneration of damaged neurons is limited after spinal cord injury (SCI). Recently, mesenchymal stem cell (MSC) transplantation was proposed as a potential approach for enhancing nerve regeneration that avoids the ethical issues associated with embryonic stem cell transplantation. As SCI is a complex pathological entity, the treatment of SCI requires a multipronged approach. The purpose of the present study was to investigate the functional recovery and therapeutic potential of human MSCs (hMSCs) and polymer in a spinal cord hemisection injury model. Rats were subjected to hemisection injuries and then divided into three groups. Two groups of rats underwent partial thoracic hemisection injury followed by implantation of either polymer only or polymer with hMSCs. Another hemisection-only group was used as a control. Behavioral, electrophysiological and immunohistochemical studies were performed on all rats. The functional recovery was significantly improved in the polymer with hMSC-transplanted group as compared with control at five weeks after transplantation. The results of electrophysiologic study demonstrated that the latency of somatosensory-evoked potentials (SSEPs) in the polymer with hMSC-transplanted group was significantly shorter than in the hemisection-only control group. In the results of immunohistochemical study, beta-gal-positive cells were observed in the injured and adjacent sites after hMSC transplantation. Surviving hMSCs differentiated into various cell types such as neurons, astrocytes and oligodendrocytes. These data suggest that hMSC transplantation with polymer may play an important role in functional recovery and axonal regeneration after SCI, and may be a potential therapeutic strategy for SCI.

Lymphatic filariasis due to Brugia malayi infection was endemic in several areas of South Korea. The infection was controlled, or disappeared, in most areas, with the exception of the remote southwestern islands of Jeonranam-do, including the Heugsan Islands. To discover its current situation, a small-scale survey was performed on the Heugsan Islands in September 2000. A total of 378 people, 151 male and 227 female, living in 8 villages (6 on Daeheugsan-do, 1 on Daejang-do, and 1 on Yeongsan-do) were subjected to a night blood survey for microfilaremia, and physical examination for elephantiasis on the extremities. There were 6 (1.6%) microfilaria positive cases, all in females aged 57-72 years, and from only two villages of the Daeheugsan-do area. There were 4 patients with lower leg elephantiasis, but they showed no microfilaremia. The results show that a low-grade endemicity of filariasis remains on the Daeheugsan-do.
