STUDY DESIGN: A retrospective study. OBJECTIVES: To examine the radiologic and clinical results of patients classified as excessive translation and excessive angulation, treated by posterolateral fusion only, or posterolateral fusion with posterior lumbar interbody fusion in isthmic spondylolisthesis. SUMMARY OF LITERATURE REVIEW: Isthmic spondylolisthesis is usually treated by PLF only or PLF with PLIF. But it is not reported the clinical and radiologic results classified by translation type. MATERIALS AND METHODS: Patients who had received surgery for spondylolisthesis between January 2005 to January 2010, there were 56 for whom follow-up observations were possible for 2 years. According to the fusion methods and preoperative flexion-extension simple radiograph, we classified as excessive translation and excessive angulation by segmental instability and as PLF and PLIF by surgical methods. We examine the clinical results(Visual Analogue Scale, Oswestry Distability Index, operation time, blood loss, complication rate) and the radiologic results(reduction rate of slippage, change of segmental angle, reduction ratio of disc height, bone union). RESULTS: In radiologic results, excessive angulation(group II) did not show significant difference from excessive translation(group I) in terms of reduction rate of slippage, change of segmental angle, reduction ratio of disc height, bone union. But we found excessive translation-PLIF(group I-B) was better than excessive translation-PLF(group I-A) and excessive angulation-PLIF(group II-B) was better than excessive angulation-PLF(II-A) in terms of reduction ratio of disc height(P<0.05). In clinical results, both sides group did not show significant difference in operation time, blood loss, complication rate. CONCLUSIONS: In spondylolisthesis patients, excessive translation group(I) and excessive angulation group(II) did not show significant difference in radiologic results and clinical results. But both sides group showed the PLF with PLIF was better than the PLF only in terms of reduction ratio of disc height.

Behcet's disease is a multisystem disorder presented with recurrent oral and genital ulcerations as well as ocular involvement. The principal manifestations in the urinary system are glomerulonephritis, cystitis, epididymitis, orchitis, and genital ulcerations. Urethrovaginal fistula is an unusual complication. The primary lesion of the disease is a small vessel vasculitis with endothelial deposition of immunocomplexes, and consequent inflammatory and necrotizing process of the vascular wall. We experienced a 19-year-old woman with Behcet's disease, who had a large urethrovaginal fistula on the anterior vaginal wall. The size of fistula was 2x1cm. For this patient, we tried combining bulbocavernosus muscle and labial fat pad flap (Martius flap) urethral reconstruction. This operative method seemed to be safe and effective for the urethral defect with Behcet's disease.

Purpose:
We aimed to assess local tumor progression (LTP) rate and associated prognostic factors in 92 patients who underwent radiofrequency ablation (RFA) using saline-perfused electrodes to treat hepatocellular carcinoma (HCC) (≤ 5 cm).
Materials and Methods:
Total 92 patients with 148 HCCs were treated with RFA using salineperfused electrodes, from 2009 to 2015. We retrospectively evaluated technical success, technique efficacy, and LTP rates. Potential prognostic factors for LTP were perivascular tumor, subphrenic tumor, artificial ascites, tumor size (≥ 2 cm), and previous treatment of transarterial chemoembolization. Analysis was performed by lesion, rather than by person.
Results:
During follow-up period from 1 to 97.4 months, total cumulative LTP rates were 7.9%, 11.4%, and 14.6% at 1, 3, and 5 years, respectively. These values were significantly higher in the perivascular (35.1%; p = 0.009) and subphrenic group (38.9%; p = 0.002) at 5-year. We did not observe any significant difference in LTP according to other prognostic factors (p > 0.05).
Conclusion
RFA with saline-perfused electrode is a safe and effective treatment modality for HCC (≤ 5 cm), with lower LTP rates. Nevertheless, perivascular and subphrenic HCCs demonstrated higher LTP rate than other sites. It is imperative to note that perivascular and subphrenic location of HCC are associated with a high risk of local recurrence, despite the use of salineperfused electrodes.

The leiomyoma of the uterus is most common benign genital tumor in women of reproductive age but occurs in the vagina rarely and may be confused with a variety of vaginal tumors. A preoperative diagnosis is seldom made. Recently we experienced a case of vaginal leiomyoma arising in the anterior vagina wall and concomitant uterine leiomyoma, so we report this case with a brief review of literature.

PURPOSE: Laparoscopic surgery has become the standard method of radical nephrectomy within the urological community. We compared the safety and efficacy of different techniques for laparoscopic radical nephrectomy (LRN) in a single medical center. MATERIALS AND METHODS: Between June 2002 and August 2007, we performed LRN for renal cell cancer in 45 cases by a transperitoneal approach (TLRN), in 21 cases by a retroperitoneal approach (RLRN), and in 32 cases by a hand-assisted approach (HLRN), and the results of each approach were compared. Surgical results such as operative time, estimated blood loss (EBL), transfusion rate, hospital stay, complications, and pathologic results were reviewed retrospectively and analyzed by one-way ANOVA. RESULTS: There were no significant differences in demographic data among the 3 groups. The pathologic reports showed clear cell type in 97 cases and chromophobe type in 1 case. For each group (TLRN vs. RLRN vs. HLRN), the mean operative time was 207.9+/-57.06 vs. 211.8+/-52.85 vs. 184.4+/-49.43 minutes, respectively (p=0.03); the EBL was 135.0+/-29.40 vs. 153.8+/-45.59 vs. 183.4+/-89.25 ml, respectively (p=0.14); time to oral intake was 2.3+/-0.79 vs. 1.2+/-0.54 vs. 2.6+/-0.84 days, respectively (p<0.01); and the hospital stay was 6.7+/-0.77 vs. 5.4+/-0.73 vs. 8.2+/-1.51 days, respectively (p<0.01). There were no severe complications. The pathologic surgical margins were all negative. CONCLUSIONS: LRN can be performed efficiently and effectively with the transperitoneal, retroperitoneal, and hand-assisted techniques. Operators may select the technique for LRN according to their own preferences. In our experience, RLRN may protect the organ from injury and promote the recovery of lifestyle because of the early recovery of bowel movement.

PURPOSE: Gap junction intercellular communication(GJIC) is an important mechanism of the bystander effect in herpes simplex thymidine kinase/ganciclovir(HSVtk/GCV) gene therapy Therefore, we attempted to enhance the bystander effect in vitro by exogenous overexpressing connexin 37(Cx37) in cells to increase GJIC. METHODS: NIH3T3 cells were transfected with the Cx37 and HSVtk gene or the HSVtk gene alone by the calcium phosphate method, and we detected their expression from these cells by RT-PCR. GCV-mediated cytotoxicity and the bystander effect of each transfectant was then assessed and compared. RESULTS: Cells transfected with HSVtk became sensitive to low concentration of GCV. We found significantly increased cytotoxicity in HSVtk/GCV gene therapy after introduction of the HSVtk and Cx37 genes together compared with the cytotoxicity seen after introduction of the HSVtk gene in vitro. Co-expression of the HSVtk and Cx37 genes potentiates HSVtk/GCV gene therapy through the bystander effect. CONCLUSION: These results indicated that the increase of GJIC using Cx37 have potentiated the by stander effect of HSVtk/GCV therapy, and may be a new approach to improve response in suicidal cancer gene therapy.
