Idiopathic hypertrophic spinal pachymeningitis (IHSP) is a rare inflammatory disease characterized by hypertrophic inflammation of the dura mater and various clinical courses that are from myelopathy. Although many associated diseases have been suggested, the etiology of IHSP is not well understood. The ideal treatment is controversial. In the first case, a 55-year-old woman presented back pain, progressive paraparesis, both leg numbness, and voiding difficulty. Initial magnetic resonance imaging (MRI) demonstrated an anterior epidural mass lesion involving from C6 to mid-thoracic spine area with low signal intensity on T1 and T2 weighted images. We performed decompressive laminectomy and lesional biopsy. After operation, she was subsequently treated with steroid and could walk unaided. In the second case, a 45-year-old woman presented with fever and quadriplegia after a spine fusion operation due to lumbar spinal stenosis and degenerative herniated lumbar disc. Initial MRI showed anterior and posterior epidural mass lesion from foramen magnum to C4 level. She underwent decompressive laminectomy and durotomy followed by steroid therapy. However, her conditions deteriorated gradually and medical complications occurred. In our cases, etiology was not found despite through investigations. Initial MRI showed dural thickening with mixed signal intensity on T1- and T2-weighted images. Pathologic examination revealed chronic nonspecific inflammation in both patients. Although one patient developed several complications, the other showed slow improvement of neurological symptoms with decompressive surgery and steroid therapy. In case of chronic compressive myelopathy due to the dural hypertrophic change, decompressive surgery such as laminectomy or laminoplasty may be helpful as well as postoperative steroid therapy.

Urinary incontinence is defined as the involuntary and inappropriate loss of urine to failure to emit normal responses as the bladder fills, or inability to reach the bathroom in sufficient time. This study was undertaken to estimate the incidence of urinary incontinence and to determine the correlates of urinary incontinence among women. Subjects of this survey consisted of 408 women, 26 to 83 years old in Incheon. The results of this study are as follows. 1. Of the subjects 50.7% reported urine loss once or twice per year and 28.5% reported incontinence on a regular basis at least once per month. 2. 40.5% of women reported small volume accidents of only 1 to 2 drops, 31.4% ; 1 t-spoon, 16.9% : 1 T-spoon, while 10.1% of women couldn't estimate the volume of urine loss. 3. The volume of urine loss was great enough to require a change of garment (undergarments or outer garments) in 73%. But only 3.8% of those used some type of pads. 4. 56.5% of incontinent women didn't talk about their urinary incontinence with other persons because they felt that urinary incontinence was shameful(38.4%), was not a disease(31.6%), was incurable in spite of treatment(27.4%) and was fearful of being uncured (2.6%). 5. Only 15.5% of urinary incontinent women had sought treatment. 6. The incidence of urinary incontinence was significantly higher in women who had more pariety and uterine-ovarian disease, older age, worrying about where toilets were when they visited new places or voiding anxiety, nocturia and frequency, but was significantly lower in women who had coffee intake. The incidence of urinary incontinence was not related to smoking and enuresis. The results indicate that urinary incontinence is common among young and middle-aged women. That few seek treatment for urinary incontinence suggests a need for more information about women's attitudes toward urinary incontinence and more attention to this problem by health care providers.

The surgical treatment of extensive urethral strictures remains a controversial topic; although techniques have evolved, there is still no definite method of choice. Since 1968, when Orandi presented an original technique for one-stage urethroplasty using a penile skin flap, the Orandi technique has become the most prevalently used one-stage procedure for anterior urethral strictures. We present a 20-year follow-up experience with one-stage reconstruction of long urethral strictures using a longitudinal ventral tubed flap of penile skin, with some important technical changes to Orandi's original technique to overcome the deficient vascularity caused by periurethral scar tissue. In 1997, a 55-year-old male patient complained of severe voiding difficulty and a weak urinary stream because of transurethral resection of the prostate due to benign prostatic hyperplasia. Another 47-year-old male patient had the same problem due to self-removal of a Foley catheter in 2002. In both patients, a urethrogram demonstrated extensive strictures involving the long segment of the anterior urethra. A rectangular skin flap on the ventral surface of the penis was used considering the appropriate length, diameter, and depth of the neourethra. The modified Orandi flap provided a pedicled strip of penile skin measuring an average of 8 cm. The mean duration of follow-up was 20.5 years. A long-term evaluation revealed stable performance characteristics without any complications.

가와사끼병은 전신성 혈관염을 일으키는 질환중의 하나로 여러 장기들을 침범할 수 있다. 신장증세로는 농뇨, 혈뇨, 단백뇨, 간질성 신염, 급성 신부전증, 용혈성 요독 증후군, 신반흔 등이 있다. 가와사끼병의 신장침범에 대한 병리기전은 아직 알려져 있지 않지만, 자가면역질환으로 인한 것으로 사려된다. 가와사끼병이 요로감염 이 후에 발병한다는 몇몇 보고들이 있었다. 하지만, 이미 보고된 논문들에 포함된 많은 요로감염 환자들은 신장방광 초음파, DMSA 스캔이나 배뇨중 요도방광조영술 등을 모두 받은 경우는 없었다. 이에 저자들은 급성 신우신염이 재발한 후 불완전 가와사끼병이 발생한 고도의 방광요관역류가 있는 8개월 남아를 보고하는 바이다. 급성 신우신염은 가와사끼병의 초기 증세일 수 있다. 그런 경우, 환아가 가와사끼병으로 확진되더라도 요로감염 진료지침에 따라 요로기형에 대한 이미지 검사를 시행할 필요가 있다고 생각한다.

Purpose: Urinary tract infection (UTI) is one of the common infectious diseases in children. Several imaging modalities can be used to confirm the presence of acute pyelonephritis (APN). Among them the 99mTcdimercaptosuccinic acid renal scan (DMSA scan) is used as a gold standard for diagnosis. Ultrasonography technology is evolving. Therefore, in this study, we investigated the sensitivity and specificity of Power Doppler ultrasonography (PDU) compared to the results from the previous study. Methods: There were 260 patients included in this study, aged between 1 and 12 months old. The patients were admitted to the Yeungnam University Medical Center between January 2008 and December 2015. All patients underwent both DMSA scan and PDU within 5days of admission. Voiding cystourethrography (VCUG) was performed in 195 patients with abnormal DMSA scan or PDU. Results: The diagnostic sensitivity of APN using PDU was 45.5% and specificity was 85.5% in 260 patients following detection of a defect on DMSA scan that was defined as APN. The diagnostic sensitivity and specificity of PDU for VUR were 65.5 % and 60.1%, respectively. The diagnostic sensitivity and specificity of DMSA scan for VUR were 95.7% and 14.1%, respectively. Conclusion: PDU has a high specificity but low sensitivity, so there are limitations in using it to replace a DMSA scan for the diagnosis of APN in children. DMSA scan and PDU have different sensitivity and specificity in diagnosis of VUR, respectively. Therefore, we suggest that the sensitivity and specificity of each test can be helpful in diagnosing APN and VUR when used in conjunction.

교차성 신전위는 두 개의 신장이 정중선의 같은 편에 나란히 위치하는 선천성 신장병이다. 대개 기형은 오른쪽에 있고 융합되어 있는 경우가 융합되지 않는 경우의 8배에 달한다. 교차성 신전위는 흔한 질환은 아니지만, 영아에서 복부에 낭성 종물이 만져지고 반대편에 신장이 없는 경우에는 고려해 보아야 한다. 다낭 형성 이상을 동반한 융합된 교차성 신전위는 대부분 초음파로 진단되므로 진단을 위해 더 이상의 검사가 필요하지 않은 경우가 많다. 그러나 방사선 동위원소를 이용한 신주사로 교차성 신전위의 기능여부를 파악해야 하고, 배설성 방광요로조영술로 방광요관 역류나 신우요관이행부의 협착이 있는지 확인해야 한다. 다낭 형성 이상을 동반한 융합된 교차성 신전위에 대한 연구는 거의 없는 실정으로 저자들은 발열, 복통을 주소로 내원한 3세 남아에서 초음파를 시행하여 다낭 형성 이상을 동반한 융합된 교차성 신전위 1례를 경험하였기에 보고하는 바이다.

Background: Contraction of anal sphincter muscle produces severe pain in perianal surgery postoperatively. Recent reports have indicated that effective and prolonged pain relief can be obtained by the injection of small doses of morphine into the subarachnoid space. We attempted to use this technique for perianal surgery and investigated postoperative pain control and its side effects. Methods: Forty five patients scheduled for hemorrhoidectomy and anal fistulectomy were studied to determine the minimal effective dose of intrathecal morphine for postoperative analgesia. In order to control the pain, 7 mg of 0.5% hyperbaric bupivacaine with 0.05 mg (group I), 0.1 mg (group II) and 0.15 mg (group III) of morphine hydrochloride was injected with a 25 gauge spinal needle into the subarachnoid space. We estimated the duration of analgesia until the pain score attained to above 3 in 10 cm VAS (visual analogue scale) and incidence of itching, nausea and vomiting by percentage, headache, backpain and respiratory depression by positive and negative. We also checked the time of self-voiding. Results: The mean time of analgesia was $10.3{\pm}1.54$, $19.7{\pm}2.22$ and $20.3{\pm}2.29$ hours in group I, II and III respectively. Urinary retention of group I, II and III after block persisted for an average of $20.3{\pm}2.31$, $21.2{\pm}2.51$ and $23.3{\pm}3.74$ hours. Nausea and vomiting were observed 33%, 53%, 67% and itching was observed 53%, 67%, 80% in group I, II and III respectively and respiratory depression did not occur in all groups. Conclusions: It is not necessary to use more than 0.1mg of intrathecal morphine in perianal surgery because analgesia is not prolonged and side effects are increased.
