The Circle Nephrostomy Tube: An Attractive Nephrostomy Drainage System Following Complex Percutaneous Nephrolithotomy
Objective
To describe our experience with the circle nephrostomy tube (NT) (Cook Medical), a drainage system uniquely designed for use after multiple-access percutaneous nephrolithotomy (PNL).
Methods
A retrospective review of 1317 consecutive patients undergoing 1599 PNLs at IU Health Methodist Hospital was performed. All multiple access cases utilizing circle NTs were reviewed and analyzed. The method of insertion of circle NT was demonstrated.
Results
A total of 1843 accesses were obtained in 1599 renal units (RUs): 380 upper pole, 129 interpolar, and 1334 lower pole. Multiple accesses in this series were required in 282 RUs (17.6%). Following multiple-access PNL, circle NTs, Cope loop, and reentry Malecot NTs were inserted in 91 RUs (32.3%), 208 RUs (73.8%), and 31 RUs (11%), respectively. None of the patients who had circle NT experienced clogging, dislodgement, or obstruction of the tube. The cost of circle, Cope loop, and Malecot NTs are 121.73 USD, 95.20 USD, and 81 USD, respectively.
Conclusion
Circle NTs are easy to insert, secure, cost-effective compared with inserting two NTs. Circle NTs provide excellent drainage and facilitate secondary procedures
Fistule carotido-caverneuse post-traumatique
Introduction : La fistule carotido-caverneuse (FCC) est une complication rare, mais grave des traumatismes craniofaciaux pouvant engager le pronostic fonctionnel oculaire et le pronostic vital. elle rĂ©alise une communication anormale entre le systĂšme artĂ©riel carotidien et le sinus caverneux.Buts : Rapporter un cas de FCC directe post-traumatique et Ă©tudier les aspects cliniques, diagnostiques et thĂ©rapeutiques de cette pathologie.Observation : Nous rapportons un cas de FCC apparue dans les suites dâun traumatisme craniofacial et survenue chez un homme de 25 ans ayant Ă©tĂ© victime dâun accident de la voie publique. Le diagnostic a Ă©tĂ© suspectĂ© devant lâapparition, au 19Ăšme jour dâhospitalisation, dâune exophtalmie unilatĂ©rale gauche pulsatile associĂ©e Ă un important chĂ©mosis et Ă une pupille arĂ©flectique. Une artĂ©riographie cĂ©rĂ©brale pratiquĂ©e 9 jours aprĂšs la constatation de lâexophtalmie a objectivĂ© une large FCC gauche. Une embolisation au moyen de deux ballonnets intravasculaires largables et de lâinjection de colle biologique a Ă©tĂ© rĂ©alisĂ©e au mĂȘme temps sans incidents permettant dâobtenir lâocclusion complĂšte de la fistule. LâĂ©volution a Ă©tĂ© marquĂ©e par la rĂ©gression de lâexophtalmie et du chĂ©mosis et par lâamĂ©lioration partielle de lâacuitĂ© visuelle.Conclusion : Le traitement des FCC est urgent et est principalement basĂ© sur la neuroradiologie interventionnelle. en effet, lâangiographie cĂ©rĂ©brale constitue lâexamen clĂ© et possĂšde un double intĂ©rĂȘt diagnostique et thĂ©rapeutique.Mots clĂ©s : fistule carotido-caverneuse, traumatisme craniofacial, artĂ©riographie cĂ©rĂ©brale, embolisation
Predictors of Enucleation and Morcellation Time During Holmium Laser Enucleation of the Prostate.
Objective
To examine predictors of enucleation and morcellation times within a large cohort of men undergoing holmium laser enucleation of the prostate (HoLEP) for benign prostatic hypertrophy.
Materials and Methods
Preoperative, perioperative, and postoperative clinical characteristics were available from men treated with HoLEP between 1998 and 2013 at Indiana University Health Methodist Hospital. Stepwise linear regression was performed to determine clinical variables which are associated with enucleation and morcellation times.
Results
We identified 960 patients who underwent HoLEP. Average (range) enucleation time was 65.7 (11-245) minutes and morcellation time was 19.7 (3-260) minutes. History of anticoagulation was associated with a small decrease in enucleation time (P = .013) whereas increasing HoLEP specimen weight was associated with increasing enucleation time (P <.001). History of intermittent catheterization, urinary tract infections (UTI), presence of dense prostatic tissue (colloquially referred to as âbeach ballsâ), and increasing specimen weight were associated with increasing morcellation time (P <.05 each). Having HoLEP performed by a less experienced urologist was associated with longer enucleation and morcellation times.
Conclusion
Prostate volume is significantly associated with increased enucleation and morcellation times during HoLEP. Additionally, history of UTI and clean intermittent catheterization (CIC) is associated with modest increases in enucleation and morcellation times. Dense enucleated prostate tissue significantly impacts the ability to morcellate effectively. Increasing surgeon experience can significantly improve both enucleation and morcellation efficiency
Renal cell carcinoma in children: Case report and literature review
Renal cell carcinoma is infrequent in children; consequently it is important to communicate its diagnosis and follow up. The behaviour of this type of tumor is better characterized in adults and in this setting the treatment of choice is surgical resection. However, the place of chemo- and radiotherapy has not been well defined. Here, we present a 9-year-old boy with renal cell carcinoma demonstrating only hematuria without any pathological physical examination findings. The mass was described by abdominal ultrasonography and computed tomography in the left kidney. After the left nephroureterectomy, the patient was given no adjuvant therapy
Comparison of Perioperative Outcomes Between Holmium Laser Enucleation of the Prostate and Robot-Assisted Simple Prostatectomy
Objectives: To compare perioperative outcomes for patients undergoing holmium laser enucleation of the prostate (HoLEP) and robotic-assisted simple prostatectomy (RSP) for benign prostatic hypertrophy (BPH).Methods: Patient demographics and perioperative outcomes were compared between 600 patients undergoing HoLEP and 32 patients undergoing RSP at two separate academic institutions between 2008 and 2015.Results: Patients undergoing HoLEP and RSP had comparable ages (71 vs 71, pâ=â0.96) and baseline American Urological Association Symptom Scores (20 vs 24, pâ=â0.21). There was no difference in mean specimen weight (96âg vs 110âg, pâ=â0.15). Mean operative time was reduced in the HoLEP cohort (103 minutes vs 274 minutes, pâ<â0.001). Patients undergoing HoLEP had lesser decreases in hemoglobin, decreased transfusions rates, shorter hospital stays, and decreased mean duration of catheterization. There was no difference in the rate of complications Clavien grade 3 or greater (pâ=â0.33).Conclusions: HoLEP and RSP are both efficacious treatments for large gland BPH. In expert hands, HoLEP appears to have a favorable perioperative profile. Further studies are necessary to compare long-term efficacy, cost, and learning curve influences, especially as minimally invasive approaches become more widespread
Clinical Significance of G6PD Variants among Palestinians
Conclusion: We conclude that children with G6PD A-deficiency are also susceptible to AHA, but demonstrate in direct comparison within this same population that G6PD Mediterranean and G6PD Cairo are more severe forms of deficiency than G6PD Aâ. Further, we show that the heretofore poorly studied G6PD Cairo may be associated with lowâlevel, chronic hemolysis. This study illustrates favism is a significant public health problem in Gaza due to fava beans as a staple in the diet and the coexistence of polymorphic G6PD deficiency variants in the society. Favism is an easily preventable and manageable genetic disorder with the proper awareness, intervention and education programs
Surfaces roughness effects on the transmission of Gaussian beams by anisotropic parallel plates
Influence of the plate surfaces roughness in precise ellipsometry experiments
is studied. The realistic case of a Gaussian laser beam crossing a uniaxial
platelet is considered. Expression for the transmittance is determined using
the first order perturbation theory. In this frame, it is shown that
interference takes place between the specular transmitted beam and the
scattered field. This effect is due to the angular distribution of the Gaussian
beam and is of first order in the roughness over wavelength ratio. As an
application, a numerical simulation of the effects of quartz roughness surfaces
at normal incidence is provided. The interference term is found to be strongly
connected to the random nature of the surface roughness.Comment: 18 pages, Journal of Physics D: Applied Physics, volume 36, issue 21,

Cardiovascular disease management in people with diabetes outside North America and Western Europe in 2006 and 2015
Aim: Optimal treatment of cardiovascular disease is essential to decrease mortality among people with diabetes, but information is limited on how actual treatment relates to guidelines. We analysed changes in therapeutic approaches to anti-hypertensive and lipid-lowering medications in people with Type 2 diabetes from 2006 and 2015.
Methods: Summary data from clinical services in seven countries outside North America and Western Europe were collected for 39Â 684 people. Each site summarized individual-level data from outpatient medical records for 2006 and 2015. Data included: demographic information, blood pressure (BP), total cholesterol levels and percentage of people taking statins, anti-hypertensive medication (angiotensin-converting enzyme inhibitors, calcium channel blockers, angiotensin II receptor blockers, thiazide diuretics) and antiplatelet drugs.
Results: From 2006 to 2015, mean cholesterol levels decreased in six of eight sites (range: â0.5 to â0.2), whereas the proportion with BP levels > 140/90 mmHg increased in seven of eight sites. Decreases in cholesterol paralleled increases in statin use (range: 3.1 to 47.0 percentage points). Overall, utilization of anti-hypertensive medication did not change. However, there was an increase in the use of angiotensin II receptor blockers and a decrease in angiotensin-converting enzyme inhibitors. The percentage of individuals receiving calcium channel blockers and aspirin remained unchanged.
Conclusions: Our findings indicate that control of cholesterol levels improved and coincided with increased use of statins. The percentage of people with BP >Â 140/90Â mmHg was higher in 2015 than in 2006. Hypertension treatment shifted from using angiotensin-converting enzyme inhibitors to angiotensin II receptor blockers. Despite the potentially greater tolerability of angiotensin II receptor blockers, there was no associated improvement in BP levels.Centro de EndocrinologĂa Experimental y Aplicad
