A penile fracture is an injury caused by the rupture of the tunica albuginea. We report an uncommon case of penile fracture with the complete urethral rupture in a 48-year-old man who sustained the injury during the sexual intercourse. He presented with acute penile pain, swelling on the ventral aspect of the penile shaft and the inability to pass urine associated with urethral bleeding. Retrograde urethrography revealed the complete obstruction of the urethra. Exploration and repair of the penile fracture with the urethra rupture were performed. The patient recovered successfully with good erectile and voiding function.

Purpose: The objective of this study were to evaluate the location of ureteral stones and the diameter of the ureter in patients with renal colic. Materials and Methods: We retrospectively reviewed the records of 95 consecutive patients who presented to the emergency department with renal colic in whom urinary stones were diagnosed by computed tomography between January 2009 and August 2009. The size and location of the stones were investigated. The length and diameter of unaffected ureters were also measured. Results: The mean size of the stones was 4.87±3.49 mm (range, 0.9-22 mm). Stones were located at ureterovesical junction (UVJ) in 44 cases (46.3%), proximal ureter in 29 (30.5%), distal ureter in 16 (16.8%), ureteropelvic junction (UPJ) in 5 (5.2%), and the ureter crossing external iliac vessel (UEIV) in 1 case (1%). The mean length of the ureter was 226.8±20.8 mm (range, 175-286 mm). The mean diameter of the ureter was 3.40±0.61 mm (range, 1.9-5.3 mm). The mean diameter of the UEIV was 3.28±0.59 mm (range, 2.2-5.3 mm). Conclusions: The UPJ and UEIV were not common sites of ureteral stones. The smaller the stones, the closer to the UVJ that the stones were located. Spontaneous passage of the stones was most frequently observed for stones in the UVJ. The UEIV was not significantly narrower than the other parts of the ureter.

본 연구는 레진 시멘트의 색 안정성을 평가하여, 레진 시멘트의 변색에 의한 심미 수복물의 실패의 가능성을 평가하고자 시행하였다. 4종의 이원중합형 레진 시멘트인 Panavia-F (PA; KURARAY), Duolink (DL; BISCO), Variolink II (VL; Ivoclar Vivadent),및 RelyX Unicem (UC; 3M ESPE)과 1종의 자가중합형 레진 시멘트인 Resiment Ready-Mix (with fluoride) CE (RM: j.l.Blosser)를 사용하였으며 , 대조군으로 복합레진 Gradia Direct (GD; GC)과 복합 레진 인레이용 Tecera Dentin A3 (TE; Bisco)를 사용했다. 각 재료 당 직경 6.5 ㎜, 두께 4.5 ㎜의 디스크형 시편 10개를 제작하였다. 중합 후 시편은 분광색채계측기인 Spectrolino (GretagMacbeth)를 이용해 CIE L^(*)a^(*)b^(*)값을 측정하고 가속시험을 위해 빛이 차단된 refrigerated bath circulator에서 60 ℃ 증류수에 30일간 보관 후에 색 측정을 시행하고, 시험 전 후의 색차를 계산하였다. 가속 시험 후 L^(*) 값은 감소하는 앙상을 보였고, a^(*) 값은 증가하는 양상을 보였지만 유의한 차이는 없었다. 반면 b^(*) 값은 유의하게 증가하였다 (p<0.05). TE가 15일과 30일 모두에서 가장 적은 색변화 (p < 0.05)를 보인 반면 GD는 15일 가속 실험 후 큰 색변화를 보였다. 30일 가속 실험 후 PA, VL, RM, DL 그리고 UC 순으로 ΔE^(*)값이 커졌으며 (p < 0.05), 30일 후 모든 레진시멘트들은 육안으로 변색을 인지할 수 있는 3 이상의 ΔE^(*) 값을 보였다. The purpose of this study was to evaluate the color stability of resin cements with accelerated test. Four dual curing resin cements: Panavia-F (KURARAY), Duolink (BISCO), Variolink-II (Ivoclar Vivadent), and RelyX Unicem (3M ESPE) and 1 self curing resin cement: Resiment CE (j. 1. Blosser) were used in this study. In control group, Gradia Anterior (GC) composite resin and Tescera Dentin (Bisco) indirect composite were used. Ten disk shape specimens were made from each resin cement. The specimens were subjected to an accelerated aging process in a refrigerated bath circulator at 60 ℃ for 15 and 30 days. Spectrophotometric analyses were made before and after 15 days and 30 days of accelerated aging time. The color characteristics (L^(*), a^(*), b^(*)) and the color difference (ΔE^(*)) of the specimens before and after immersion were measured and computed. Regardless of type of the resin cements, L^(*) value was decreased and a^(*) value was increased, but there were no significant difference. But b^(*) value was increased significantly (p < 0.05). Tescera inlay showed least color change (p < 0.05), but Gradia showed notable color change after 15 days. After 30 days on accelerated aging, ΔE^(*) value was increased (Panavia-F < Variolink-II < Resiment CE < Duolink < Unicem) (p < 0.05), but there were no significant difference among Panavia-F, Variolink-II, and Resiment CE groups. After 30 days of accelerated aging, ΔE^(*) value of all resin cements were greater than 3.0 and could be perceived by the human eye.

Colossal magnetoresistance is closely related to (but is not) the abrupt change of electrical resistivity in the vicinity of Curie temperature, which is caused by the temperature dependent paramagnetic-ferromagnetic phase transition and concurrent change of electrical conducting mechanism. A resistivity-temperature equation is presented to fully describe the overall behavior, especially the abrupt change. The main ingredients of the equation are a simple effective media theory and a function for the temperature dependent fraction of ferromagnetic phase. The model fits very well to the measured resistivity-temperature curve of La_(0.7)Ca_(0.3)MnO₃.

Purpose: Hysterectomy, regardless of the surgical technique, increases the risk of having to undergo stress urinary incontinence surgery later in life. Furthermore, transvaginal hysterectomy may cause some changes in the normal architecture and tension of the tissues surrounding the pelvic floor, and this may also cause some changes in the continence mechanisms of the bladder and urethra. We investigated if there are any adverse effects of concomitant vaginal hysterectomy on the outcomes of a tension-free vaginal tape procedure. Materials and Methods: The outcomes of the tension-free vaginal tape (TVT)/transvaginal total hysterectomy(VTH) group were compared with that of the TVT group in terms of cure and improvement of incontinence, satisfaction with the procedure and the complications. The preoperative evaluation included history taking, physical examination and stress tests and determining the stress-related leakage, the emptying ability, the anatomy, the protection and the inhibition(SEAPI) scores. The outcomes were evaluated at over one year after operation. Results: The cure and improvement rates were 77.5% and 15% in the TVT group, and 88.9% and 7.4% in the TVT/VTH group, respectively, without any statistical difference between the two groups. The rates of patient- satisfaction with the procedure were similar in two groups. There were no serious or long term complications related to the procedure except for a case of local hematoma in the hysterectomy site, which was controlled conservatively. Conclusions: Our findings suggest that a TVT operation can be done simultaneously with vaginal hysterectomy with similar results as those of TVT operation only. In addition, it is thought that the simultaneous TVT operation in a patient who is undergoing hysterectomy and has urinary stress incontinence deserves to be recommended in a positive light.

Purpose: We evaluated the influence of preoperative physical examination (PE) and urodynamic study (UDS) findings on objective postoperative bladder emptying, the subjective development of bladder storage symptoms, and patient-reported success of correction of stress urinary incontinence (SUI). Materials and Methods: From January 2007 to August 2008, a total of 159 female patients with SUI underwent transobturator midurethral sling surgery (TOT). The patients were selected for SUI, with no overactive bladder (OAB) symptoms, no detrusor overactivity (DO) on UDS, no pelvic organ prolapse, and no history of prior anti-incontinence surgery. Of these patients, 128 patients (aged 38-74 years; mean age, 51.8±7.1 years) with follow-up of at least 12 months were included in the analysis. All patients had PE and UDS findings, including Q-tip testing, free maximal flow rates (Qmax), filling cystometry, Valsalva leak point pressure, detrusor pressure at maximal flow, and maximal urethral closing pressure. The primary outcome was postoperative voiding dysfunction, defined as the subjective feeling of not empting one’s bladder completely and a postvoid residual ≥100 ml. A secondary outcome, "cure" of SUI, was defined as "a negative result on the cough stress test and no subjective complaint of urine leakage." We analyzed the preoperative parameters by univariate and multivariate regression for voiding dysfunction, de novo OAB, cure rate, and the patients’ satisfaction. Results: Patients with a preoperative Qmax < 15 ml/s (7 patients) had a tendency for postoperative voiding dysfunction compared with those with a Qmax 15 ml/s (15 patients) (35.0% vs. 13.9%, respectively; p=0.046). No other preoperative parameters had a statistically significant influence on postoperative voiding dysfunction. Receiver operating characteristic (ROC) analysis revealed that Qmax was a good predictor because the area under the ROC curve value of Qmax was 0.81 (95% CI: 0.73 to 0.89, p<0.001). The univariate and multivariate analysis of the preoperative PE and UDS parameters demonstrated that no significant differences and no independent risk factors were related to the postoperative de novo OAB, cure rate, or the patients’ satisfaction. Conclusions: These findings suggest that preoperative UDS results, especially Qmax, could be used to predict postoperative voiding dysfunction after the TOT procedure.
