Article | 2015 | European Journal of Radiology84 ( 3 ) , pp.346 - 349

Background Laparoscopic cholecystectomy is the first step treatment in cholelithiasis. The purpose of this study was to establish a radiologic view on prediction of conversion from laparoscopic cholecystectomy to open surgery. Methods This study included 176 patients who had undergone laparoscopic cholecystectomy. Preoperative ultrasonographic findings were assessed and we gave points to each finding according to results from correlation analysis. After the scoring we investigated the relationship between ultrasonographic findings and conversion from laparoscopic cholecystectomy to open surgery. Results Scoring significantly predict . . .ed failure in laparoscopic approach (AUC = 0.758, P = 0.003,). Optimal cut off score was found to be 1.95 with 67% sensitivity and 78% specificity. Score > 1.95 was a risk factor for failure in laparoscopic approach [odds ratio = 7.1(95% CI,2-24.9, P = 0.002)]. There were 8 subjects out of 36(22%) with high score underwent open surgery while 4 out of 128 (3%) subjects with low score needed open surgery (p = 0.002). Negative predictive value of 128/132 = 97%. Mean score of whole study population was 1.28 (range 0-8.8) and mean score of subjects underwent open surgery was 3.6 while it was 1.1 in successful laparoscopic approach group (p < 0.001). Mean Age and BMI were similar between groups (p > 0.05). Sex of subjects did not affect the success of surgery (p > 0.05). Conclusion The contribution of preoperative ultrasonography is emphasized in many studies. Our study suggests quantitative results on conversion from laparoscopic cholecystectomy to open surgery. We believe that radiologists have to indicate the risk of conversion in their ultrasonography reports. © 2014 Elsevier Ireland Ltd. All rights reserved Daha fazlası Daha az

Is computed tomography necessary to determine liver injury in pediatric trauma patients with negative ultrasonography?

Kaya, U. | Cavus, U. Y. | Karakilic, M. E. | Erdem, A. B. | Aydin, K. | Isik, B. | Abacioglu, Serkan

Article | 2013 | EUROPEAN JOURNAL OF TRAUMA AND EMERGENCY SURGERY39 ( 6 ) , pp.641 - 646

Purpose Abdominal trauma is the third most common cause of all trauma-related deaths in children. Liver injury is the second most common, but the most fatal injury associated with abdomen trauma. Because the liver enzymes have high sensitivity and specificity, the use of tomography has been discussed for accurate diagnosis of liver injury. Methods Our study was based on retrospective analyses of hemodynamically stabil patients under the age of 18 who were admitted to the emergency department with blunt abdominal trauma. Results Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were significantly higher as a . . .result of liver injury. In the patients whose AST and ALT levels were lower than 40 IU/L, no liver injury was observed in the contrast-enhanced computed tomography (CT). No liver injury was detected in the patients with AST levels lower than 100 IU/L. Liver injury was detected with contrast-enhanced CT in only one patient whose ALT level was lower than 100 IU/L, but ultrasonography initially detected liver injury in this patient. Conclusions According to our findings, abdominal CT may not be necessary to detect liver injury if the patient has ALT and AST levels below 100 IU/L with a negative abdominal USG at admission and during follow-up Daha fazlası Daha az

Article | 2012 | Diagnostic and Interventional Radiology18 ( 3 ) , pp.277 - 281

PURPOSE This prospective, controlled clinical study aimed to assess the diagnostic values of detrusor wall thickness (DWT), postvoid residual urine volume (PVR), and prostate volume in men with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS During an 18-month period, a total of 243 males were included in the study. Three groups were assessed due to their International Prostate Symptom Score (IPSS): men with normal lower urinary tracts (n=51; control group), men with mild LUTS (n=60; Group 1), and men with moderate to severe LUTS (n=132; Group 2). DWT, bladder, and prostate volumes and PVR were measured by suprapubic ultr . . .asonography. DWT was measured when the bladder was full (DWT-1) and when it was empty (DWT-2). RESULTS The mean age for the study population was 60.0±0.6 years, while the mean IPSS for the whole group was 8.0±0.4. Both the bladder and prostate volumes in Group 2 were statistically significantly higher than the control group and Group 1. The mean DWT-1 values were significantly lower in the control group when compared to Groups 1 and 2. However, when study groups were compared with each other, no statistical significance was noticed (1.12 vs. 1.17 mm). In contrast, the mean PVR and DWT-2 values were significantly different in each group. There was a significant correlation between IPSS questionnaire results and all individual parameters. CONCLUSION Suprapubic transabdominal ultrasonographic assessment of the lower urinary tract in a noninvasive manner allows the clinician to assess LUTS severity in men without morbidity. Additional studies are necessary to provide further conclusions regarding this clinical procedure. © Turkish Society of Radiology 2012 Daha fazlası Daha az

Article | 2002 | Journal of Clinical Ultrasound30 ( 8 ) , pp.496 - 498

Migration of an intrauterine contraceptive device (IUD) to the urinary bladder is very rare. We describe a case in which transabdominal sonography demonstrated such migration of an IUD in a 30-year-old woman who sought treatment for pelvic pain and dysuria. The IUD had originally been inserted 10 years earlier, and the patient had given birth without complications 2 years before the onset of her symptoms. Cytoscopic examination confirmed the diagnosis and allowed removal of the IUD. © 2002 Wiley Periodicals, Inc.

Transrectal ultrasound-guided prostate biopsy: Current approach [Transrektal ultrasonografi eşliginde prostat biyopsisi: Mevcut yaklaşım]

Akduman B. | Crawford E.D.

Review | 2010 | Turk Uroloji Dergisi36 ( 1 ) , pp.25 - 32

Over the past decade, a significant number of modifications have been made to the technique for prostate biopsy. In this report, we reviewed the literature regarding transrectal ultrasound-guided prostate biopsy (TRUS-BX) in terms of the various techniques of prostate biopsy, number of cores, prophylactic antibiotic selection and use, patient preparation and pain-controlling techniques applied before the procedure. The proposed advantages/ disadvantages of transitional zone and seminal vesicle biopsies were also summarized. According to the literature, TRUS-BX rather than transperineal approach should be preferred as the technique o . . .f choice in most men undergoing a prostate biopsy. The laterally directed sextant biopsy and extended biopsy approaches decrease the false-negative rate that occurs with the conventional sextant biopsy approach. As a conclusion, considering the baseline biopsy protocol, the current advice is the use of an extended biopsy scheme (12 biopsy cores without transitional zone). Laterally directed biopsies from the anterior horn should be included. Repeat as well as saturation biopsies should include the transitional zone. Local anesthesia using transrectal ultrasound-guided lidocaine injection provides adequate periprostatic nerve blockage and is recommended to reduce the pain associated with prostate biopsy. Broad-spectrum antibiotic therapy should be administered to reduce the risk of infection Daha fazlası Daha az

Lumbar puncture or identification of the epidural space is technically more difficult in children. Prior obtained information regarding the distance from skin to the dura mater may be useful as leading to an increase in success. We studied the anatomy of the posterior lumbar spine at the L4,5 intervertebral space in 137 children, using ultrasonography. Children aged between 7 and 12 years in whom weight and height are in 3-97 percentiles (recommended for healthy Turkish boys and girls) were investigated. The measured distance from skin to dura mater was found significantly higher in girls (2.59 ± 0.44 cm) than boys (2.43 ± 0.46 cm) . . .(p<0.05). Prediction of the posterior dural depth at L4-5 level was obtained using single linear regression equation. All demographic variables correlated significantly with the dural depth in both sexes. In girls the skin-duramater distance achieved highest correlation ranks with weight and body surface area (BSA): 'dural depth' (cm) = 1.094 + [0.048 × weight (kg)], r = 0.79, p<0.01 and 'dural depth' (cm) = 0.337 + [2.119 × BSA (m2)], r = 0.76, p<0.01). We concluded that the distance between the skin and the dura mater at the level of L4,5 interspace could be predicted using a statistical model based on the age, weight, height or BSA of children aged between 7-12 years old Daha fazlası Daha az

We present the case of a 37-year-old woman with a history of 2 consecutive insertions of intrauterine contraceptive devices (IUDs) 3 years before she was referred to us for sonographic evaluation of lower abdominal pain. The first of the IUDs was presumed to have been expulsed spontaneously, and 3 months after insertion of the second device, the patient had begun experiencing lower abdominal pain. Medical treatment with antibiotics and spasmolytics had been unsuccessful. We performed transvaginal sonography, which revealed the presence of an IUD in the uterus and a 2-cm linear metallic echogenic area in the left ovary, believed to r . . .epresent another IUD. Anteroposterior radiography confirmed that there were 2 IUDs in the pelvis, and CT demonstrated 1 IUD in the uterus and another in the left ovary. The patient underwent laparoscopic removal of the ovarian IUD and was discharged in good condition. To our knowledge, this is the first report of migration of an IUD to the ovary detected on transvaginal sonography. We recommend consideration of this possibility during evaluation of women with unexplained chronic pelvic pain. © 2004 Wiley Periodicals, Inc Daha fazlası Daha az

Article | 2005 | Journal of the Turkish German Gynecology Association6 ( 1 ) , pp.49 - 51

A case of pelvic septic trombophlebitis, which is a rare complication of gynecologic surgery is presented. In the diagnosis of this clinical entity ultrasonography, computed tomography or magnetic resonance is helpful, but mostly diagnostic laparoscopy must be performed to make a definite diagnosis. In the treatment, antibiotics combined with low molecular weight heparins are the first choice. In this case report the diagnosis and clinical management of a rare postoperative complication; pelvic septic trombophlebitis is being discussed.

Purpose: The aim of this study was to evaluate the correlations between laboratory findings and ultrasonographic measurements of renal length and cortical thickness in patients receiving follow-up for chronic kidney disease (CKD). Methods: A total of 41 CKD patients (18 males and 23 females; mean age, 65.2 years; range, 42 to 85 years) with a low glomerular filtration rate who did not require renal replacement therapy were included in this prospective study. Patients were followed up with laboratory assays at bimonthly intervals and with ultrasonography performed twice a year. Renal cortical thickness, renal length, and estimated gl . . .omerular filtration rate (eGFR) values were compared using the paired-samples t test. Additionally, Pearson correlation analysis was conducted between renal length and cortical thickness measurements and eGFR values to assess kidney function. Results: At the beginning of the study and after 24 months, mean eGFR values of the 41 patients were 35.92 mL/min and 28.38 mL/min, respectively. The mean renal length was 91.29 mm at the beginning of the study and 90.24 mm at the end of the study. The mean cortical thickness was 5.76±2.05 mm at the beginning of the study and 5.28±1.99 mm at the end of the study. A statistically significant positive association was found between eGFR and mean renal length (r=0.66, Daha fazlası Daha az

Hepatic lipomas are extremely rare benign tumors. Because these lesions are asymptomatic, they are usually discovered incidentally. There is no risk of malignant degeneration. The imaging appearance of lipomas is characteristic. Computed tomography, magnetic resonance imaging, and sonographic findings of these lesions can help in characterization by allowing specific diagnosis. In computed tomography and magnetic resonance imaging, simple lipomas demonstrate fat attenuation or signal intensity and do not enhance after contrast material administration. A 46-year-old woman was admitted to the hospital because of dyspeptic symptoms. Li . . .ver ultrasound was suggestive of lipomas, whereas the diagnosis was confirmed by computed tomography and magnetic resonance imaging. In this presentation, we evaluated the effectiveness of ultrasonography, computed tomography, and magnetic resonance imaging in the diagnosis of lipomas.
