Urinary retention is a common complication after abdominal surgery. Urinary retention causes infection and damage to the urinary system, prolonging hospital stays and increasing health care costs in the end. Because medical personnel tend to regard urinary retention as not being a serious problem, it is hard to find any method which decrease the postoperative urinary retention. There are few papers reporting the incidence and the factors which influence the postoperative urinary retention. The purpose of this study is to evaluate the incidence of postoperative urinary retention and to identify the factors which affect the postoperative urinary retention. We retrospectively reviewed 296 patients out of 338, who had been undergone laparotomy under spinal or general endotracheal anesthesia during a three month period from January to March 1998. We reviewed nursing, anesthetic and operative records. Among the 296 patients, male were 189(63.9%) and female were 107(36.1%). Postoperative urinary retention occurred in 71 patients(24%). The incidence rate was higher in female patients than in male (M : F=18% : 35%). Factors that in fluence the incidence of postoperative urinary retention were sex, duration of operation, the amount of fluid given the patient, preoperative history of dysuria, and preoperative insertion of a urinary catheter. Among those factors, preoperative urinary catheter insertion is the most effective preventive measure in lowering the incidence of postoperative urinary retention (Spearman correlation coefficient, r=-.462). Shortening the operation time and sparing the fluid which is infused during operation are important in preventing postoperative urinary retention. Preoperative urinary catheter insertion may be helpful in lowering urinary retention in those patients who have a possibility of postoperative urinary retention.

Although there are many peri-operative measures to reduce core temperature loss during operation, rapid drop has been experienced in the first sixty minutes following induction of general anesthesia. Recently, preoperative warming has been emphasized to prevent inadvertant hypothermia during operation. The purpose of this study is to find the effect of preoperative warming on reducing rectal temperature drop in surgical patients. With informed consent, 46 female adult patients, scheduled for total abdominal hysterectomy or salpingo-oophorectomy in the Seoul National University Hospital from September 3, 1996 to September 19, 1996 were divided into two groups. The variables of age and body surface were matched between the two groups as possible. Among them, 24 patients were preparatively covered up to the shoulders with a forced-air warming blanket(WARM TOUCHTM). set between 36-40degrees C for prewarming, and the other 22 patients(control group)were not before the induction of anesthesia. Rectal temperature was measured by mercury thermometer for rectum after admission to the operating room and by rectal probe which was inserted in the rectum just before the induction during the operation. The rectal temperature was monitored and recorded at every fifteen minutes for the first sixty minutes after the induction and each step during the surgery(intubation, surgical draping, peritoneum opening, one hour and the end of the operation) Collected data were analyzed by means of t-test, Repeated Measures Analysis of Variance with PC-SAS. The results of this study are as following. (1) There was no significant difference between the two groups in age, weight, height, room temperature, basal rectal temperature, operation time. (2) Temperature gradient of the rectal temperature in the warming group was less steeper than that in the control roup during the first sixty minutes after general anesthesia. (3) The rectal temperature measured at every fifteen minutes for the first sixty minutes and the end of surgery after the general anesthesia showed the difference between the two groups during surgery. (4) There was no rectal temperature difference during the intubation, however there was significant temperature difference between the two groups from draping to the end of surgery. In conclusion, prewarming of the surgical patient before induction resulted in increased the skin temperature and heat content, which relieved the dangerous core temperature drop which is potential to be provoked within one hour after induction of the surgical patients and kept the rectal temperature higher than that of the control group during surgery. The suggestions from this study shown below : First, further study is needed to find the preventive effect of the core temperature drop in the first sixth minutes after anesthetic induction by preoperative warming for gastrorectal, thoracic surgery patients who man have the core temperature drop during the operation. Second, in other to keep patient normothermia during the surgery, it needs to study whether using pre-and peri-operative warming can prevent hypothermia or not. Finally, the study of the peroperative warming effect on surgical patients' relaxation and thermal discomfort before the operation is needed because most patients in the case group said to have felt thermal comfort ; 'comfortable' and 'good'.

BACKGROUND: Malnutrition among inflammatory bowel disease (IBD) may arise from factors including inadequate dietary intake, malabsorption, and progression of disease. IBD has been reported an increased prevalence of low bone mass. The aims of the present study were to evaluate the nutritional status and to investigate the correlation between bone mineral density (BMD) and nutrient factors in patients with IBD. METHODS: A total of 41 subjects were classified into normal group (n=21) and malnourished group (n=20) by the subjective global assessment result. We surveyed the dietary habit, nutrient intake, and BMD. RESULTS: Subjects' average age was 36.7 years old, and included 26 ulcerative colitis and 15 Crohn's disease. The serum C-reactive protein (CRP) was significantly higher and serum calcium was significantly lower in the malnourished group. Lower bone density subjects were more in the malnourished group but no significant difference. Intake of energy, protein, carbohydrate, fiber, iron, sodium, potassium, zinc, vitamin B6, vitamin C and folate were significantly lower in the malnourished group. The BMD of malnourished group showed correlation with triceps skin fold thickness (TSF), CRP, dietary calcium, phosphorous, iron, animal iron, zinc and vitamin. CONCLUSIONS: The results suggested that adequate intake of nutrients is important to prevent bone loss and systemic education programs are need for IBD patients.

PURPOSE: With the development of bipolar device, which complement the weak points of conventional monopolar device, TURP became more appliable in large volume prostate. We evaluated the possibility and effectivity of bipolar TURP in large volume prostate by analysing treatment results. MATERIALS AND METHODS: Total 78 male patients who received bipolar TURP in our center between April 2004 and December 2006, were divided into two groups based on prostate volume (>75g = large volume prostate group, <75g = control group). We compared each of age, prostate volume, resection volume, operation time, IPSS, Qmax, change of serum Na+ & hemoglobin, and perioperative complications. RESULTS: There was no statistical difference between preoperative IPSS and postoperative IPSS between the both groups. In preoperative status, Qmax was statistically higher in small volumed prostate group. But, after bipolar TURP, Qmax of each group were significantly improved, and statistical difference between the two groups were disappeared. Patient age, prostate volume, resection weight, hemoglobin down, hospitalization day, catheterized duration were statistically higher in the large volume prostate group. But, in the clinical aspect, these differences were acceptable. Immediate postoperative hematuria and hypothermia were more frequent in large volume prostate group. Long term complication rates were almost the same in two groups, and there was no TUR syndrome in both groups. CONCLUSION: Transurethral resection of large volume prostate (>75g) using bipolar device is as effective as of general (<75g) prostate hyperplasia. Bipolar TURP can be another therapeutic option of large volume prostate, which in the past indicated open prostatectomy, to escape from higher surgical morbidity.

PURPOSE: Postoperative long-term follow-up studies after orchiopexy are rare as compared for other studies such as for histological changes and proper operative age. We analyzed the five-year long-term follow-up results after orchiopexy, expecting a proper prognosis of testicular growth. MATERIALS AND METHODS: A total of 57 patients were selected from a follow-up study in 211 boys who underwent orchiopexy between January 1999 and July 2001. Patients were divided in several categories(operation age, testis consistency, pre-operational position of the testis) and were analyzed by examination of the previous medical records, preoperative and postoperative testicular volume(measured by ultrasonography), follow- up history taking, and from a physical examination. RESULTS: For the 57 patients, 14 patients had bilateral and 43 patients had unilateral cryptorchidism. All of the cryptorchid testes were smaller than a normal testis in the unilateral group of patients as determined by testis ultrasonography. Sorting by operation age, only patients that received orchiopexy within two years from birth showed a significant recovery of testicular volume percentage(operated testis/normal testis x100%: in the unilateral group) at follow-up. Sorting by consistency, the patients with normal testicular consistency showed a significant recovery of testicular volume percentage(operated testis/normal testis x100%: in the unilateral group) at follow-up. Sorting by the preoperative position of the testis, the proximity of the testis to the scrotum was a significant factor for recovery of delayed cryptorchid testicular growth. CONCLUSIONS: Orchiopexy performed at less than two years from birth and the proximity of the testis to the scrotum were significant factors for recovery of delayed cryptorchid testicular growth. Consistency of a cryptorchid testis can be a meaningful factor for expectation of testicular growth by the establishment of an objective measurement for testicular consistency and studies for histological correlation.
Follow-Up Studies

PURPOSE: To evaluate functional MR imaging of the motor speech area with and without motor stimulation duringthe rest period. MATERIALS AND METHODS: Nine healthy, right-handed volunteers(M:F=7:2, age:21-40years) wereincluded in this study. Brain activity was mapped using a multislice, gradient echo single shot EPI on a 1.5T MRscanner. The paradigm consisted on a series of alternating rest and activation tasks, performed six times. Each volunteer in the first study(group A) was given examples of motor stimulation during the rest period, while eachin the second study(group B) was not given examples of a rest period. Motor stimulation in group A was achieved bycontinuously flexing five fingers of the right hand. In both groups, maximum internal word generation was achievedduring the activation period. Using fMRI analysis software(Stimulate 5.0) and a cross-correlationmethod(background threshold, 200; correlation threshold, 0.3; ceiling, 1.0; floor, 0.3; minimal count, 3),functional images were analysed. After correlating the activated foci and a time-signal intensity curve, theactivated brain cortex and number of pixels were analysed and compared between the two tasks. The t-test was usedfor statistical analysis. RESULT: In all nine subjects in group A and B, activation was observed in and adjacentto the left Broca's area. The mean number of activated pixels was 31.6 in group A and 27.8 in group B, adifference which was not statistically significant(P>0.1). Activities in and adjacent to the right Broca 's areawere seen in seven of group A and four of group B. The mean number of activated pixels was 14.9 in group A and 18in group B. Eight of nine volunteers in group A showed activity in the left primary motor area with negativecorrelation to the time-signal intensity curve. The mean number of activated pixels for this group was 17.5. Inthree volonteers, activation in the right primary motor area was also observed, the mean number of activatedpixels in these cases was 10.0. CONCLUSION: During the rest period, functional MR imaging of the motor speechcenter combined with motor stimulation was more effective than that without stimulation, and simultaneouslyprovided mapping of the primary motor area.

BACKGROUND: Recently, the diagnosis of non-alcoholic fatty liver disease (NAFLD) has been made more frequently, as the use of ultrasonography on health screening has been on the rise. The aim of this study was to elucidate the relationship between NAFLD and the metabolic syndrome defined by NCEP-ATP III criteria. METHODS: A total of 1,675 subjects, who attended for routine physical check?ups, were screened. Among those, 401 subjects were selected after excluding the subjects with either significant alcohol consumption, evidence of viral or toxic hepatitis, significant liver or renal dysfunction, or overt thyroid disease. NAFLD was diagnosed if the subjects had a "bright liver" on ultrasonographic examination. The diagnosis of metabolic syndrome was made according to the criteria of NCEP-ATP III established in 2001. RESULTS: The prevalence of NAFLD was 27.2%. Blood pressure, body weight, body mass index, waist circumference, and serum levels of total cholesterol, triglyceride, fasting glucose and liver enzymes were higher among the subjects with NAFLD than the control. The prevalence of obesity, IFG/DM, dyslipidemia and hypertension was higher in the NAFLD group. The prevalence of the metabolic syndrome was 19.2%, which was higher in the NAFLD group than the control group. The odds ratio of NAFLD for the metabolic syndrome was 6.458 (95% C.I. 3.178~13.124). CONCLUSION: NAFLD was closely associated with the metabolic syndrome regardless of the presence of obesity.

Inflammatory myofibroblastic tumor (IMT) of the urethra is a tumor composed of myofibroblasts and a mixed inflammatory infiltrate that rarely undergoes malignant transformation. The etiology and the biologic behaviors of IMTs are still unknown. Extensive pathologic examination is important to prevent misdiagnosis and the need for long-term follow up is emphasized. Recently, we experienced a case of a inflammatory myofibroblastic tumor of the urethra in a young female. To our knowledge, this is the first documentation of such an entity in published reports. So we present our experience with a review of literature.
