Aims : Fournier gangrene is a rapidly progressive necrotizing fasciitis involving the genitalia. It can be treated with antibiotics and immediate debridement along with treatment of the predisposing condition. We evaluated the prognostic factors, clinical characteristics and treatment of patients of the Fournier gangrene. Methods : The subjects were 40 male patients diagnosed with Fournier gangrene who visited Wonkwang University Hospital, Iksan, Korea between January 1991 and December 2000. Their medical records were reviewed with respect to demographics, medical history, symptoms and signs, physical examination, laboratory data, bacteriology, extent of disease, clinical course, and therapy. The extent of disease was quantified for each patient using a modification of the diagram used to assess the extent of burns. Results : The average age was 55.3 years (range 29.6-92.8). Of the 40 patients, 11 died (36%) and 29 survived (64%). Anorectal infections were the underlying local disease most commonly associated with high mortality (75%). Although the most common associated illness was diabetes, it was not related to the prognosis (death rate: 20.0%). In contrast, the death rate was highest in chronic renal failure, reaching 50%. The mortality rate increased with the duration of symptoms before hospitalization. Patients with < 6% surface area involvement were more likely to survive. On admission, serum blood urea nitrogen (s-BUN) and serum creatinine were significantly higher in the patients who died. Conclusion : Survival is associated significantly with anorectal infection, chronic renal failure, the duration of symptoms before hospitalization, the extent of gangrene, and s-BUN and creatinine level on admission.
PurposeA seminal vesicle cyst in combination with ipsilateral renal agenesis is rarely encountered. We present cases of this disease entity with symptoms, which were treated with a laparoscopic approach as a minimally invasive surgical treatment.Materials and MethodsWe experienced 4 patients with seminal vesicle cysts and ipsilateral renal agenesis. The mean age was 45.8 years. Chief complaints were perineal pain and hematospermia. Seminal vesicle cysts and remnant ureters were excised by laparoscopic surgery with transperitoneal approaches.ResultsThe mean operative time was 133.8 minutes. The mean hospital stay was 6.8 days. There were no operative complications or transfusions.ConclusionIn our report, patients of congenital seminal vesicle cyst associated with renal agenesis are presented. Laparoscopy is considered a minimal invasive management of these combined anomalies, providing a good image and an easy approach.
PurposeUltrasound (US) is highly sensitive in the detection of renal masses. However, it may not be able to differentiate benign and malignant lesions in smaller masses. The purpose of this study was to determine the diagnostic efficacy of contrast-enhanced ultrasound (CEUS) for small renal masses.Materials and MethodsFrom January 2011 to December 2013, a total of 85 patients underwent CEUS for evaluation of renal masses. Of these patients, CEUS findings were retrospectively analyzed for small renal cell carcinoma (RCC) cases (n=38) and angiomyolipoma (AML) cases (n=11). The tumor echogenicity and enhancement patterns and degrees were evaluated. The diagnostic efficacy of CEUS in differentiating the two diseases was compared.ResultsOn CEUS, the findings of diffuse heterogeneous enhancement (observed in 78.9% of RCCs and 27.3% of AMLs, p=0.003), washout from hyperenhancement or iso-enhancement to hypoenhancement in late phase (73.7% of RCCs and 18.2% of AMLs, p=0.001), and perilesional rim-like enhancement (57.9% of RCCs and 9.1% of AMLs, p=0.006) were significantly different between AML and RCC cases. The corresponding sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 86.8% (33/38), 63.6% (7/11), 89.2% (33/37), 58.3% (7/12), and 81.6% (40/49), respectively.ConclusionsOur results suggest that the characteristic CEUS features could have diagnostic value in the evaluation of small renal mass. CEUS showed a higher diagnostic efficacy than conventional US for differentiating RCC and AML.
We investigated performance parameters of disposable flexible ureterorenoscopy (LITHOVUE) in patients with renal stones in a prospective, multicenter, observational study. Sixty two patients who underwent ureterorenoscopic surgery by LITHOVUE were included. Surgeons using a numerical scale, evaluated the maneuverability of the scopes and general perceptions of visibility related to the monitor and irrigation systems. General pain and fatigue scores were evaluated and compared to existing scopes. Mean patient age was 57.3 years and stone size was 15.4 mm. Clinical success of overall stone removal was 82.3%. Complications occurred in 4 cases of the Clavien classification grade I in a single case and II in 3 cases. Comparative parameters of maneuverability, perception of the monitor system and perception of the irrigation channel were 2.5, 2.5, and 3.0, respectively. The most favorable evaluation of physical strain was about ‘shoulder fatigue’ and ‘hand fatigue’. Unfavorable evaluations were recorded for ‘wrist stiffness’ and ‘thumb fatigue’. Maximal deflection angles of 270° were preserved in 53 cases (85.5%). No pre-stenting procedure and the longer operative time were significant predictors of poorly-preserved deflection angles <270°. LITHOVUE showed good maneuverability and perception scores for the monitor and irrigation systems. LITHOVUE received favorable evaluations on pain and fatigue scores.
Objective: To determine whether listening to music during transrectal ultrasound (TRUS)-guided 12-core needle prostate biopsy decreases anxiety, pain and dissatisfaction among patients and results in a more comfortable and better tolerated procedure. Patients and Methods: 76 male patients who underwent TRUS-guided prostate biopsy between March 2013 and June 2014 were randomized into the following groups: no music (group I, n = 38) or classical music (group II, n = 38) during the procedure. Before TRUS-guided prostate biopsy, lidocaine gel was instilled into the rectum. Patient anxiety levels were quantified using the State-Trait Anxiety Inventory. A visual analog scale (0-10) was used for self-assessment of satisfaction, discomfort and willingness among patients to have a repeat TRUS-guided prostate biopsy. Results: Demographic characteristics, mean age, procedure duration and procedure indications did not differ statistically between the two groups. The mean anxiety level and mean pain score of group II were significantly lower than those of group I (p = 0.001 and p = 0.003, respectively). Group II also had a significantly higher mean satisfaction score than group I (p = 0.007). Before the procedure, heart rate and systolic blood pressure were similar in groups I and II; however, after the procedure, levels were lower in group II than in group I (heart rate, p = 0.014; systolic blood pressure, p = 0.011). Conclusion: Listening to music during TRUS-guided prostate biopsy significantly reduced patients' feelings of pain, discomfort and dissatisfaction. Music can serve as a simple, inexpensive and effective adjunct to sedation during TRUS-guided prostate biopsy. We recommend playing music during TRUS-guided prostate biopsy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
