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: 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 > or =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.

PURPOSE: We evaluated the influence of urinary stone components on the outcomes of ureteroscopic removal of stones (URS) by electrohydraulic lithotripsy (EHL) in patients with distal ureteral stones. MATERIALS AND METHODS: Patients with a single distal ureteral stone with a stone size of 0.5 to 2.0 cm that was completely removed by use of EHL were included in the study. Operating time was defined as the time interval between ureteroscope insertion and complete removal of ureteral stones. Ureteral stones were classified into 5 categories on the basis of their main component (that accounting for 50% or more of the stone content) as follows: calcium oxalate monohydrate (COM), calcium oxalate dihydrate, carbonate apatite (CAP), uric acid (UA), and struvite (ST). RESULTS: A total of 193 patients (131 males and 62 females) underwent EHL. The mean operating time was 25.1+/-8.2 minutes and the mean stone size was 1.15+/-0.44 cm. Calcium oxalate stones accounted for 64.8% of all ureteral stones, followed by UA (19.7%), CAP (8.3%), and ST (7.2%) stones. The mean operating time was significantly longer in the UA group (28.6+/-8.3 minutes) than in the COM group (24.0+/-7.8 minutes, p=0.04). In multivariate analyses, the stone size was negatively associated with the odds ratio (OR) for successful fragmentation. UA as a main component (OR, 0.42; 95% confidence interval, 0.20 to 0.89; p=0.023) was also found to be significantly important as a negative predictive factor of successful fragmentation after adjustment for stone size. CONCLUSIONS: The results of the present study suggest that successful fragmentation by URS with EHL could be associated with the proportion of the UA component.

PURPOSE: To evaluate effect of modified arthroscopic pull-out suture technique which used number 5-nonabsorbable suture material for tibia intercondylar eminence comminuted fractures. MATERIALS AND METHODS: There were 21 cases of tibia intercondylar emimence fracture which arthroscopic treated at our hospital between 1999 and 2004. However the study population only included 12 cases in which a number 5-nonabsorbable suture material (Ethibond No. 5) was used for tibia intercondylar eminence comminuted fractures and minimum 1-year follow-up has gone. The average follow-up period was 18.5 months (range, 12 to 42 months). Lachman test and KT-2000 athrometer test were evaluated at the pre-and post-operation. Clinical results of all patients were evaluated with the Meyers and Mckeever 's criteria. RESULTS: In all 12 cases, the normal range of motion and sports activities were recovered at the final follow-up. When tested for anterior instability with KT-2000 arthrometer, there were no different between normal knee and operated knee. Clinical results by Meyers and Mckeever's criteria were excellent in 10 patients and good in 2 patients. CONCLUSION: We obtained early mobilization and stable fixation in modified arthroscopic pullout suture technique for tibia intercondylar eminence comminuted fractures. Patients can early return to his job. This technique seems to be one of the effective operative techniques for treatment of tibia intercondylar eminence comminuted fractures.

Objective:
To investigate the incidence and survival outcomes of ovarian carcinosarcoma in Korea between 1999 and 2018.
Methods:
Patients diagnosed with ovarian carcinosarcoma between 1999 and 2018 were identified from the Korea Central Cancer Registry (KCCR) and their information was collected. Age-standardized incidence rates (ASRs), annual percent changes (APC), and relative survival rates of ovarian carcinosarcoma were calculated and compared to those of epithelial ovarian cancer.
Results:
According to the KCCR, 458 cases of ovarian carcinosarcoma were detected, and accounted for 1.5% (458/30,679) of all epithelial ovarian cancers in Korea between 1999 and 2018. The ASR of ovarian carcinosarcoma between 1999 and 2018 was 0.064 per 100,000 women. The incidence rate of ovarian carcinosarcoma increased during the study period, with an ASR of 0.029 per 100,000 in 1999 and 0.073 per 100,000 in 2018. The APC of ovarian carcinosarcoma during 1999–2018 was 5.86 (p<0.001). The median overall survival (OS) of patients with ovarian carcinosarcoma was 39 months, and the 5-year OS rate was 42.5%.Among ovarian carcinosarcomas, patients with localized stages showed better clinical outcomes than those with regional or distant stages (5-year OS, 60.8%, 57.9%, and 32.8%, respectively; p<0.001). In addition, younger (<50 years) patients showed better OS than older (≥50 years) patients (5-year OS, 52.6% vs. 40.2%; p<0.001).
Conclusion
Our nationwide registry-based study demonstrated that the incidence of ovarian carcinosarcoma increased from 1999 to 2018 in Korea. Patients with advanced-stage disease and older age (≥50 years) had poorer survival outcomes.

Purpose:
The optimal treatment for patients with stage III non-small cell lung cancer (NSCLC) remains controversial. This study aimed to investigate prognostic factors and clinical outcome in stage III NSCLC using real-world clinical data in the Korean population.
Materials and Methods:
Among 8,110 patients with lung cancer selected from 52 hospitals in Korea during 2014-2016, only patients with stage III NSCLC were recruited and analyzed. A standardized protocol was used to collect clinical information and cox proportional hazards models were used to identify risk factors for mortality.
Results:
A total of 1,383 patients (46.5% had squamous cell carcinoma and 40.9% had adenocarcinoma) with stage III NSCLC were enrolled, and their median age was 70 years. Regarding clinical stage, 548 patients (39.6%) had stage IIIA, 517 (37.4%) had stage IIIB, and 318 (23.0%) had stage IIIC. Pertaining to the initial treatment method, the surgery group (median survival period: 36 months) showed better survival outcomes than the non-surgical treatment group (median survival period: 18 months, p=0.001) in patients with stage IIIA. Moreover, among patients with stage IIIB and stage IIIC, those who received concurrent chemotherapy and radiation therapy (CCRT, median survival period: 24 months) showed better survival outcomes than those who received chemotherapy (median survival period: 11 months), or radiation therapy (median survival period: 10 months, p<0.001).
Conclusion
While surgery might be feasible as the initial treatment option in patients with stage IIIA NSCLC, CCRT showed a beneficial role in patients with stage IIIB and IIIC NSCLC.

We report here on a rare case of primary malignant melanoma of the female urethra. A 69-year-old female presented at our hospital with a several month history of dysuria, poor stream, gross hematuria, intermittent blood spots, and a painful mass at the external urethral meatus. The physical examination revealed a soft, small, chestnut-sized lesion through the urethral orifice. The mass was tan colored, ulcerated, covered with necrotic tissue, and protruded from the external urethral meatus. The mass was removed by wide local excision under spinal anesthesia. The pathological diagnosis was malignant melanoma of the urethra. Computed tomography of the abdomen as well as a whole-body bone scan showed no evidence of metastasis. The patient has been free of disease for 6 months postoperatively. We discuss the clinicopathologic features and treatment of this tumor.
