Extravaginal neonatal testicular torsion, although it is rare, is being recognized with increasing frequency. Furthermore, bilateral neonatal torsion is very uncommon. Because of the seriousness of the outcome due to the risk of future anorchia, this condition that requires prompt recognition and careful decision making. We experienced a case in which the patient had bilateral neonatal testicular torsion and the patient showed bilateral necrotized testes during operation. However, the histopathologic findings during operation showed a small intact portion only in the left testis. Right orchiectomy and left orchiopexy were performed, and the left testis was saved. We report here on this case with a review of the literature.

Many studies have cited occurrences of severe and long-lasting emotional disturbances of almost every kind after surgical procedures, particularly due to the sedatives or narcotics which were administered to control the post-operative pain. In order to control this post-operative pain, pediatric caudal analgesia was performed in 15 infants and children from the age 2 months to 6 years, who were to undergo lower abdomen, perineum and lower extremity surgery. They were induced with inhalation anesthoeia, using nitrous oxide, oxygen and halothane by mask before and during the block. Following the block, infants and children were turned to supine position and the initial concentration of halothane was reduced. All cases were given 10mg/kg of 1% solution of lidocaine. On examination of the level of the analgesia, 13 out of 15 cases had spread higher level than T10, with effective block for surgical procedures. The identification of the sacral cornu is easy and technical failureis lees in comparison than with the lumbar epidural block for infants and children. Thus we can perform this block successfully for infants and children without any complications or accidents. It is especially helpful in the management of postoperative cases due to the effect in control of the postoperative pain. Thus it gives satisfaction to their parents, nurses and doctors. Despite no follow-up study on postoperative emotional reactions, it was considered that there were minimal occurrences of emotional and behavioral sequelae following the hospital and surgical experiences.

A large number of terms has been applied to this clinical and pathophysiologic complex, all of which are encompassed by the designation ARDS. The use of this term,however, should not obscure the fact that the initial insults and mechanisms of lung injury vary and that therapy should be directed not only toward the secondary alterations in pulmonary function but toward the initiating event or events as well. In therapy, the use of continuous positive-pressure ventilaion(CPPV) incorporating PEEP has a well-documented role in the management of patients with ARDS. The veneficial effect of this pattern of ventilation is mainly attributable to the increase in FRC that it produces. As previously discussed, several factors combine to reduce lung volumes in patients with ARDS. Positive end-expiratory pressure overcomes threade by producing a constantly positive distending pressure across the walls of airways and alveoli; this reestablishes their patency and increases FRC. We report a case of ARDS after operation for Vesico-cervical fistula developed in a 34 years old woman and the relevant literature has been reviewed.

PURPOSE: We assessed the accuracy of urinary detection by visualization compared with a method using the urethral channel of a transurethral, three-channel urodynamic catheter. MATERIALS AND METHODS: This was a case series of 52 patients presenting with stress urinary incontinence over 2 years. Patients underwent video-urodynamic studies in both the supine and the erect positions by use of two techniques for measuring leak point pressure (LPP) by one examiner. LPP was determined as the intravesical pressure simultaneous to the starting point of urethral pressure changes through the urethral channel of a urodynamic catheter (LPP-ure) and then by visualization (LPP-vis) during different events. We also measured the time related to the provocations and the time to mark the leakage on the urodynamic machine by the examiner. RESULTS: The LPP-ure values (cough supine: 42.1+/-18.7, cough erect: 42.1+/-21.8, Valsalva supine: 42.2+/-23.3, Valsalva erect: 41.0+/-22.6 cmH2O) were significantly lower than the LPP-vis values (89.9+/-29.4, 97.4+/-30.4, 70.6+/-25.2, and 74.4+/-32.6 cmH2O, respectively, all p<0.001). Whereas the actual leakages happened during the pressure increases, urodynamic recording by visualization was done after those increases had finished. CONCLUSIONS: The use of visualization as a urinary detection method entails potential errors that cannot be adjusted for on that time scale. Our results emphasize the need to standardize the methodologies used for urinary leakage detection, because this measurement is closely related to the accuracy of measurement of leak point pressure.

PURPOSE: We have previously demonstrated that increased urethral resistance was more prominent in diabetic rats than in controls. This may result from a compressive obstruction such as damage of the urethral nerve containing nitric oxide. Another possible cause for urethral obstruction could be a constrictive obstruction such as a periurethral fibrosis. In the present study, we investigated the changes in the expression of nitric oxide synthase(NOS) isoforms(compressive obstruction) and collagen subtypes (constrictive obstruction) in the urethral tissues of non-insulin dependent diabetic rats. MATERIALS AND METHODS: Thirty-six male Sprague-Dawley rats(18 diabetic rats and 18 control rats), bred from birth, were included in this study. Diabetes mellitus was induced by intraperitoneal administration of streptozotocin(90mg/kg) on the second day after birth. Urethral tissues were harvested at 12, 24 and 36 weeks after induction of diabetes and were stained for neuronal NOS(nNOS) and Masson trichrome. We also performed reverse transcriptase-polymerase chain reaction or Western blot analysis to evaluate mRNA or protein expression of NOS isoforms and collagen subtypes in the urethral tissues. RESULTS: Immunohistochemical staining and Western blot analysis of nNOS revealed that the immunoreactivity and nNOS expression in the urethra was lower in the diabetic rats than in the controls. The Masson trichrome staining showed that there was urethral fibrosis in the diabetic rats. The mRNA or protein expression of collagen subtypes, especially type I collagen, were higher in the diabetic rat urethra than in the controls. CONCLUSIONS: These data suggest that the increased urethral resistance in diabetic rats may be attributable to a decrease in the urethral nNOS expression and an increase in collagen content. Urethral dysfunction as well as a cystopathy may play an important role in the pathogenesis of diabetes- induced voiding dysfunction. (Korean J Urol 2007;48:1050-1057)

BACKGROUND/AIMS: Choledochal cyst is an unusual but serious condition which most commonly affects Oriental people. And it is an unusual entity that has increasingly been encountered by ultrasonography and computed tomography scan, even if the symptoms are variable. METHODS: We reviewed 23 patients with choledochal cyst who were treated at the Department of Internal Medicine, Pusan Paik Hospital from April, 1986 to April 1995. RESULTS: 1) Age ranged from 14 years to 73 years, and sex ratio was 1:1.4 in male vs female. 2) The durations of symptoms varied from 4 days to several years. 3) The major clinical symptoms were right upper quardrant pain in 19 cases, jaundice in 4 cases, abdominal mass in 2 cases. One case had all of above three symptoms. 4) The diagnostic tools were ultrasonography(USG) in l7 cases, ERCP in 11 cases, abdominal CT in 11 cases, PTC in 6 cases and oral GB in 1 case. The eight cases(61.5%) were confirmed as anomalous junction of the pancreaticobiliary ductal system(AJPBS) among the 13 cases who had performed ERCP. 5) The choledochal cysts were classified into type I to V according to the classification of Todani; Fifteen cases were type I, six cases type IVa, one case was type II and one case was type V, respectively. 6) Excision of choledochal cyst and Roux-en-Y hepaticojejunostomy was performed in 10 cases, and choledocho-jejunostomy in 4 cases, and Whipple's operation in 2 cases. 7) The associated diseases were CBD stone in 8 cases, cholecystitis in 6 cases, intrahepatic stone in 2 cases, GB cancer in 1 case, and colon cancer in 1 case. CONCLUSIONS: ERCP should be used when choledochal cyst is suspected by USG, aiming at demonstrating both AJPBS and enabling the morphologic classification. In addition, Surgical procedures including the excision of choledochal cyst and Roux-en-Y hepaticojejunostomy may be effective to reduce mortality and morbidity related to complication of choleclochal cyst.
