[Air quality and human health: PM10 and respiratory diseases]

In this paper a comparison between the air quality data collected in urban and rural areas is performed taking in account the PM10 levels allowed in the European Union and in the world and is related to the increase of respiratory diseases. The parameters considered are essentially due to the anthropogenic primary pollution: particulate matter PM10, benzene and toluene, CO and Polycyclic Aromatic Hydrocarbons.

Paranasal sinuses anatomic variants: 64-slice CT evaluation

AIM

The aim of the paper was to perform a 64-slice CT evaluation of the main anatomic variants of paranasal sinuses.

METHODS

From April 2005 to January 2006, 100 patients were chosen among all those that had undergone a paranasal sinuses CT examination. They were 45 women and 55 men, all aged between 18 and 70 years, mean age 46 years; they were all caucasian. This research has been conducted using a 64-slice Siemens Somatom Volume-Zoom multidetector Spiral CT. Para-nasal sinuses CT examination has been performed through a thin axial acquisition; the patient was lying on his back and the images were processed with multiplanar reconstruction (MPR). The anatomic variants considered in this study are: concha bullosa, Haller cells, uncinate process abnormalities, agger nasi cells, ethmoidal bulla, Onodi cell, middle turbinate curvature abnormalities.

RESULTS

In this research it has been noticed that 29% of patients are affected by concha bullosa, 5% by Haller cells and again 5% by uncinate process abnormalities; 52% are affected by agger nasi cells, 15% by ethmoidal bulla, 9% by Onodi cell and 11% by middle turbinate curvature abnormalities.

CONCLUSION

By using a 64-slice CT you can get a better quality of images in terms of spatial and temporal resolution. Osteomeatal complex structures are often featured by many anatomic variants. The most of the time, percentages are the same as recent researches have shown.

Preoperative integrated imaging in paediatric cochlear implantation

Sensorineural hearing loss affects one to two children out of 1000 born apparently healthy and 9% approximately of those born with the risk of different pathologies. The origin of premature deafness is unknown in 25% of children whereas it is genetic in some cases. Prevention and early diagnosis, possibly within six to eight months, aim to avoid deafness becoming a cause of disability. The aim of the present study was to establish the optimal preoperative assessment with a diagnostic imaging protocol involving the integrated use of CT and MRI in the selection of the candidates for cochlear implantation. Twenty children were assessed, divided into three different groups: A) those who had CT only; B) those who had only MR; C) those who had both CT and MRI. The purpose was to estimate diagnostic accuracy in preoperative planning and the role of imaging in the diagnostic protocol for children's deafness. The petrous pyramid was studied with a CT Picker PQ 6000 system to high resolution in the axial and coronal planes, and with an MR Intera Philips 0.5 T device by means of acquisition of sequences B-TFE T2 3D and MIP reconstructions on radial coronal plans. This study was completed successfully for morphological brain MRI examination to complete the diagnosis. The following abnormalities were found in six patients (30%): one case of incomplete partition (Mondini malformation); two cases of vestibular aqueduct enlargement; two cases with anomalous jugular bulb positioning; one case with cochlear ossification. In the remaining 70%: eight patients had no anatomical anomalies; CT and MRI imaging were normal in six patients with minor abnormalities disclosed at surgery (one case of the stapedial artery emerging from the promontory); three anatomical variants of the round window, and two abnormal course of the facial nerve). We emphasize the importance of integrated CT and MRI imaging in the study of children with sensorineural hearing loss. The combination of CT and MRI has been shown to be superior to either modality used alone in view of "risk-free" cochear implantation. High resolution computed tomography and magnetic resonance images obtained by B-TFE T2-weighted 3D sequences help the surgeon in planning the operation and predict operative difficulty and potential complications in paediatric cochlear implant candidates.

Evaluation of normal brain development by prenatal MR imaging

PURPOSE

The aim of this study was to describe the normal pattern of development and maturation of the foetal brain with respect to gestational age as assessed with magnetic resonance imaging (MRI) and to provide an overview of the possibilities of the technique.

MATERIALS AND METHODS

Foetal cerebral MRI was performed on 56 pregnant women between 19 and 37 weeks of gestation. Half-Fourier single-shot turbo spin-echo (HASTE), true fast imaging with steady precession (FISP), T1-weighted fast low angle shot (FLASH) two-dimensional (2D) and diffusion-weighted (DW) sequences with apparent diffusion coefficient (ADC) were obtained. Biometric parameters and developmental areas of the cerebral cortex were correlated to gestational age by using the Spearman rank correlation test.

RESULT

We found a negative correlation between the germinal matrix/biparietal diameter ratio and gestational age and a positive correlation between the germinal and cortical matrix when expressed as external intraocular diameter ratio (R=0.452, p=0.02). The cortical mantle was correlated with biometric parameters, such as the biparietal diameter and the frontooccipital diameter, and with gestational age. The interhemispheric fissure, the parietooccipital fissure and the sylvian fissure were detectable by the 22nd week. In the grey matter, the mean ADC values varied from 1.76 x 10(-3) mm(2)/s (at week 19) to 0.89 x 10(-3) mm(2)/s (at week 37), whereas in the white matter, the values varied from 2.03 x 10(-3) mm(2)/s (at week 19) to 1.25 x 10(-3) mm(2)/s (at week 37).

CONCLUSIONS

MRI provides a reliable valuation of brain maturation during pregnancy.

[Pulmonary physiopathology in scleroderma: study of respiratory function in 86 patients]

OBJECTIVE

To contribute to an early diagnosis of pulmonary involvement in scleroderma by evaluating the correlation between respiratory symptoms and functional respiratory data observed.

PATIENTS AND METHODS

86 patients affected by scleroderma, 76 women and 10 men, age 14-75, underwent lung function tests, blood gas sample, CO diffusing capacity in setting and supine position, respiratory drive measurement through P0.1 and evaluation of the respiratory muscles efficiency with Maximum Inspiratory Pressure (MIP).

RESULTS

Data obtained suggested us to divide our patients in four different groups: first group where both spirometric data and pulmonary diffusion were normal; a second group with a clear reduction of pulmonary diffusion likely due to the reduction of vascular bed; a third group where we observed a restrictive ventilatory impairment due to the reduction of the compliance and a reduction of the pulmonary diffusion likely related to interstitial damage; finally, a fourth group where beside a restricted spirometric outline we have detected a more accentuated reduction of pulmonary diffusion likely due to pulmonary hypertension. Moreover, our study has highlighted a progressive decrease of MIP and Maximum Voluntary Ventilation (MVV) shifting from the first to the fourth group, suggesting reduction of the muscular efficiency with an increase of P0.1 index of activity in the respiratory drive.

CONCLUSIONS

The results could explain the dyspnea often reported by the patients affected by scleroderma even without spirometric alteration.

[Possible effects of non invasive mechanical ventilation on respiratory drive and muscles]

OBJECTIVE

To evaluate whether long-term Non-Invasive Mechanical Ventilation (NIMV) might have an effect on respiratory drive and respiratory muscles strength, measuring mouth occlusion pressure (P0,) and maximal inspiratory pressure (MIP).

PATIENTS AND METHODS

20 consecutive patients with hypercapnic respiratory failure underwent measurements of dyspnea, respiratory drive and respiratory muscles strength before hospital treatment with NIMV; those patients who showed significant improvement of gas-exchange continued home ventilation for a period of four weeks, and were readmitted to hospital for re-evaluation of Borg's scale for dyspnea, P0,1 and MIP.

RESULTS

Data obtained show a mild reduction of P0,1 and a significant improvement of respiratory muscles strength, with satisfactory dyspnea relief.

CONCLUSIONS

We conclude that unloading respiratory muscles through mechanical ventilation results in better muscle performance in the long-term that could act, together with normalization of gas-exchange, on neuromuscular respiratory drive and contribute to dyspnea relief.

[First abdominal access in gynecological laparoscopy: which method to utilize?]

The choice of the technique to enter the peritoneal cavity, during a laparoscopy, depends on a lot of variables which hinder a standardized method and, actually, it appears impossible to show, with certainty, the best method to choose for the first abdominal access in gynecological laparoscopy. The preference for one or another technique depends on the operator experience, school and speciality of the surgeon, laparoscopical upgrading and the work environment; many surgical techniques are not yet used due the limits and fears of some surgeons to change the preference in first access approaching and for the lack of operating versatility by a method or another one. A review of the scientific literature, underlines that the major problems during the first laparoscopical abdominal access are two, vascular and intestinal and their percentage is variable. In this paper we describe the large range of methods for open and closed laparoscopy and for direct access, that permit to perform a first abdominal laparoscopical access, and their major possible problems.

Cobalt nano-particles modulate cytokine in vitro release by human mononuclear cells mimicking autoimmune disease

The use of particles from micro to nanoscale provides benefits to diverse scientific fields, but because a large percentage of their atoms lie on the surface, nanomaterials could be highly reactive and pose potential risks to humans. Due to their wide range of application, Cobalt nano-particles are of great interest both in industry and in life-science. To date, there are few studies on Co nano-particle toxicology. In this respect, this study aims at evaluating in vitro the potential interference of Co nano-particles on the production of several cytokines (IL-2, IL-4, IL-6, IL-10, IFNgamma and TNFalpha) by PBMCs, comparing their effects to those of Co micro-particles and Co solution (CoCl2). Cells were cultured in Opticell flasks with escalating concentrations (10-5, 10-6 and 10-7 M), of Co nano and micro-particles and CoCl2 or without metal. Cytokines were quantified in the supernatants using a human Th1/Th2 cytokine cytometric bead array. Co micro-particles showed a greater inhibitory effect compared to other Co forms. Its inhibitory activity was detected at all concentrations and towards all cytokines, whereas Co solutions selectively inhibited IL-2, IL-10 and TNF-alpha at maximal concentration. Co nano-particles induced an increase of TNF-alpha and IFN-gamma release and an inhibition of IL-10 and IL-2: a cytokine pattern similar to that detected in the experimental and clinical autoimmunity. On the basis of the obtained data, immune endpoints should be sought in the next series of studies both in vitro and in vivo in subjects exposed to cobalt nano-particles.

Surgical strategies in cervico-mediastinal goiters

AIM

We retrospectively studied clinical picture, diagnosis, treatment and complications of patients with cervico-mediastinal goiter who underwent surgery.

METHODS

Sixty-three patients underwent surgical treatment for cervico-mediastinal goiter in the last 10 years. Thirty-two patients (50.8%) had cervico-mediastinal goiter, 24 patients (33.3%) had mediastino-cervical goiter and 7 patients (11.1%) had mediastinal goiter. Forty-seven cases were prevascular goiters and 16 were retrovascular goiters. We performed total thyroidectomy in 25 patients, subtotal thyroidectomy in 31 patients and in 7 cases the resection of residual goiter. In 50 patients we used a cervical approach, in 12 patients the cervical incision was combined with median sternotomy (6 in total) and in 1 patient with transverse sternotomy.

RESULTS

Three patients (4.7%) died in the postoperative period (2 cardio-respiratory failure and 1 pulmonary embolism). The histologic study revelead 5 (7.9%) carcinomas. Postoperative complications were: dyspnea in 7 cases (11.1%), transient vocal cord paralysis in 5 patients (7.9%), temporary hypoparathyroidism in 6 patients (9.5%) and kidney failure in 1 case (1.6%).

CONCLUSIONS

Cervicotomy is the approach of choice but in some limited cases (carcinoma, thyroiditis, retrovascular goiter, ectopic goiter) the sternotomy should be performed. Postoperative mortality and morbidity is very low, independent of surgical techniques.

Peripheral blood gene expression profiling in rheumatoid arthritis

We carried out gene expression profiling of peripheral blood mononuclear cells (PBMCs) in 29 patients with active rheumatoid arthritis (RA) and 21 control subjects using Affymetrix U95Av2 arrays. Using cluster analysis, we observed a significant alteration in the expression pattern of 81 genes (P<0.001) in the PBMCs of RA patients compared with controls. Many of these genes correlated with differences in monocyte counts between the two study populations, and we show that a large fraction of these genes are specifically expressed at high levels in monocytes. In addition, a logistic regression analysis was performed to identify genes that performed best in the categorization of RA and control samples. Glutaminyl cyclase, IL1RA, S100A12 (also known as calgranulin or EN-RAGE) and Grb2-associated binding protein (GAB2) were among the top discriminators. Along with previous data, the overexpression of S100A12 in RA patients emphasizes the likely importance of RAGE pathways in disease pathogenesis. The altered expression of GAB2, an intracellular adaptor molecule involved in regulating phosphatase function, is of particular interest given the recent identification of the intracellular phosphatase PTPN22 as a risk gene for RA. These data suggest that a detailed study of gene expression patterns in peripheral blood can provide insight into disease pathogenesis. However, it is also clear that substantially larger sample sizes will be required in order to evaluate fully gene expression profiling as a means of identifying disease subsets, or defining biomarkers of outcome and response to therapy in RA.

[Urinary incontinence in postmenopausal period: clinical and pharmacological treatments]

Urinary incontinence is a common clinical problem in female sex and occurs especially in postmenopausal women; this disease, that represents an economical problem for society, begins in young age, arises in middle age and increases in women more than 65 years old. Studies carried out on etiological factors involved in urinary incontinence show that estrogens enhance the trophism and vascularization of the muscular and fascial support of the pelvic floor, the growth of fibroblasts and the collagen metabolism in the superficial fascia in postmenopausal women. The postmenopausal estrogenic deficit could be related to many urogenital problems, but many researches performed on the effects of estrogens in urogenital postmenopausal homeostasis and of hormonal replacement therapy in postmenopausal incontinent women, did not show conclusive findings; for this reason, even if many authors attributed to menopause a role of major risk factor for incontinence, a direct correlation has never been confirmed. The treatment of postmenopausal female incontinence may be clinical and pharmacological, and includes a first step therapy (bladder training, biofeedback techniques, electrical pelvic floor stimulation) and a second step therapy (pharmacological therapy, bladder devices and surgical operations). In this review the clinical and pharmacological treatments, their efficacy and their application in incontinent postmenopausal women are described.

[Benign tumors and pseudotumors of temporo-mandibular joint: radiologic aspects]

Benign tumors and tumor-like lesions that involve temporo mandibular joint are very rare. Those more frequent are osteochondroma, chondroma, osteoma, pigmented villonodular synovitis and synovial chondromatosis. The Authors report six cases of patients affected by these pathologies in which imaging, such as TC, MRI and/or ortopantomography have been useful to have a diagnosis.

[Spontaneous rupture of duodenum: case report and review]

Although rare, injuries of the duodenum increased in frequency during the past ten years. Careful attention must be paid to them, especially in blunt trauma of the abdomen and lower thoracic regions. Often they occur along with lesions of other related structures in polytraumatized patients. X-rays are the most important mean used in diagnosis. Early diagnosis and surgical treatment are conditio sine qua non for successful results. Complete intraoperative inspection of the duodenum, careful suture of the perforation and a correct placement of drainage are essential for the prevention of postoperative complications. If the duodenal wall had lost its vitality, a gastrojejunal or duodenojejunal anastomosis or gastrostomy are performed; the duodenum is decompressed and drainage of the peritoneal cavity is established. In cases of associated injury of the pancreas or choledochus, the drainage of the extrahepatic bile duct is recommended. The Authors report a case of spontaneous rupture of duodenum in which all of the above mentioned procedures were used; they stress that only suspicion of a duodenum's rupture indicates an immediate laparotomy.

[Magnetic resonance and traditional radiology in the spine localizations of alkaptonuric ochronotic arthropathy]

AIM

To study the spine alterations in alcaptonuria with traditional radiology and magnetic resonance (MR), comparing the results of the two techniques.

PATIENTS AND METHODS

Five patients (4 males, 1 female, mean age 51 years) underwent the examinations. For the study with X-rays we performed anteroposterior and lateral scan and the images have been studied making reference to a radiographic score; it examines the alterations of the joint space and the presence of calcifications. MR scan, oriented in the three spatial planes, were performed using spin echo T1-weighted and spin echo T2-weighted sequences.

RESULTS

Both MR and X-rays pointed out, in the cases with known diagnosis, the typical alterations of the ochronosis: narrowing of the articular spaces, even osseous ankylosis, calcifications of the discs, osteophytosis, multiple disc protrusions and reactive sclerosis of the articular surfaces, evident above all to dorso-lumbar tract; nevertheless MR has been more accurate than X-rays for individualizing the lesions and recognizing alterations, such as the thickness of the anterior longitudinal ligament. In the case of new diagnosis, the MR is fundamental to recognize typical signs of the ochronotic arthropathy not well detected by X-rays.

CONCLUSIONS

Imaging techniques, first of all the MR, are essential in the differential diagnosis of ochronosis vertebral lesions with other articular diseases.

[Renal neoplasms and renal transplantation: current problems and future perspectives]

Primary carcinomas of the kidney can develop in renal transplantation in four sets of circumstances: (1) detected in the donor, (2) detected as a pre-existing neoplasm in the recipient prior to transplantation, (3) as de novo malignancies arising post-transplantation in the native kidneys of the recipient, (4) or in the graft. In Italy, any renal mass detected during harvesting does not allow the use of any organs for transplantation; however, several reports from other countries have already shown the safety and efficacy of transplanting kidneys with small (<4 cm), unifocal, subcapsular tumors, after resecting the lesion at the back table and verifying the negativity of the surgical margins; this strategy could also be evaluated in Italy to expand the donor pool. Acquired cystic kidney disease (ACKD) is commonly observed in uremic patients undergoing chronic hemodialysis (HD); numerous studies have reported an increased prevalence of renal cell carcinoma (RCC) in association with this nephropathy. The use of ultrasound, computerized axial tomography (CAT) and magnetic resonance imaging (MRI) has greatly improved the ability to detect renal tumors at earlier stages associated with ACKD and the morbidity and mortality rate, in either uremic or transplant patients. RCC in the transplanted kidney is rare and, when recognized, requires nephrectomy. However, a conservative approach with nephron sparing surgery has been reported for selected cases as a useful strategy to treat renal carcinoma in the allograft.

[Current surgical management in ovarian cancer recurrences]

Ovarian cancer is a tumor with a high trend of recurrence and this occurrence consistently increases the difficulty of the patient cure and reduces the efficacy of current treatments. The role of surgery in persistent or recurrent ovarian cancer is controversial and the type of surgery can be different according to the different stages and invasion of tumor; it can be a debulking surgery followed by chemotherapy (to eradicate the most part of ovarian cancer, leaving a minimal tumoral residue), an interval surgery (for advanced ovarian cancer stage in previously operated patients, followed by 2 or 3 inductive chemotherapy cycles and subsequently a cytoreductive redo surgery) and a cytoreductive secondary surgery, after optimal primary surgical treatment and minimal tumoral recurrence. In some cases it is possible either to perform a debulking surgery during a primary (after the conclusion of primary treatment) or a salvage or palliative surgery (to improve, after an acceptable time period, clinical symptoms in patients with progressive cancer or resistant to treatments). The aims of surgical therapy, to be performed in a patient with ovarian cancer relapse, are to reduce, as much as possible, the tumour size, to increase the quality of life and to increase the survival time; in this review different surgical techniques to be carried out in each case, selected for disease staging, for tumour cells kinetic and for surgical goals, are discussed.

Serum levels of chitotriosidase as a marker of disease activity and clinical stage in sarcoidosis

BACKGROUND

Sarcoidosis is a systemic granulomatous disease characterized by T-lymphocyte activation and lymphocyte migration into involved organs, usually the lungs. The amounts of a number of biochemical markers, such as angiotensin converting enzyme (ACE) activity, increase in the serum of patients with sarcoidosis. Chitotriosidase is an enzyme secreted by activated macrophages able to catalyze the hydrolysis of both chitin and chitin-like substrates. Chitotriosidase is involved in defense against, and in degradation of chitin-containing pathogens such as fungi, nematodes, and insects.

METHODS

Forty-three patients affected by chronic sarcoidosis, in active (23 patients) or inactive (20 patients) phase, were studied. Serum levels of chitotriosidase and ACE activity were evaluated and compared with those of 32 healthy subjects. Serum chitotriosidase concentration and ACE activity were also correlated with radiographic stage of disease.

RESULTS

Individuals with chronic sarcoidosis have higher serum chitotriosidase concentrations and ACE activity than those of normal subjects. Sarcoidosis patients in the active phase of the disease had significantly higher chitotriosidase and ACE levels than those in the inactive phase. In contrast to serum ACE activity, a significant relationship between serum levels of chitotriosidase and the four radiographic stages of the disease was observed.

CONCLUSION

Although the data need to be validated by further investigation, the observations made in this study seem to indicate that serum chitotriosidase concentrations may be a useful marker for monitoring sarcoidosis disease activity and prognosis.

Characterisation of the TAPIRO BNCT thermal facility

Dosimetry and spectrometry measurements have been carried out in the thermal column of the research fast reactor RSV-TAPIRO (ENEA-Casaccia, Rome) in order to investigate its suitability for irradiation of cells or mice, with a view to research in the interests of boron neutron capture therapy (BNCT). The thermal column consists of a graphite moderator (40 cm thick) containing a lead shield (13 cm thick) in order to shield reactor background. The irradiation volume, inside this structure, has cubic shape (18 x 18 x 18 cm3). Besides measurements of fluence and dose rates in air or in phantom performed with thermoluminescence dosemeters (TLDs) and using the activation technique, dose and fluence profiles have been generated using a method based on gel dosemeters analysed with optical imaging. To check the consistency of the results, spectrometry measurements in the same irradiation volume have been performed by means of bubble detectors.

[In vitro and in vivo effects of cefodizime and ceftriaxone on oxygen-dependent killing of neutrophils of elderly patients with exacerbation of chronic bronchitis]

The immunomodulating activity of some chemotherapeutic agents, is particularly interesting. Our study has evaluated the in vitro and in vivo effects of two third generation cephalosporins: cefodizime and ceftriaxone, on the chemiluminescence of polymorphonuclears of 20 elderly patients affected by acute exacerbation of bronchitis. Twenty healthy patients have been also evaluated in vitro. Antibiotics have been used in vitro at the concentration of 50 g/ml while in vivo a group of 10 patients have been treated with cefodizime (2g/daily in 2 divided doses), another group of 10 patients with ceftriaxone (2g/daily as a single dose); in both groups the antibiotic treatment was given for 7-10 days. A significant potentiation of chemiluminescence has been shown in both groups of patients treated in vivo; whereas the preincubation in vitro of the polymorphonuclear suspension, both in healthy patients and in elderly bronchopathic ones, with antibiotics, has not changed the activity of oxygen dependent killing. Finally, we believe that bactericidal properties of the antibiotic still remain now the most important criteria of choice in order to assure effective control of infections.

[Hepatitis C virus infection mimicking hemorrhagic fever: a case report]

Acute C hepatitis, compared with hepatitis A or B, may sometimes be associated with extrahepatic manifestations of a haematologic nature. The first case of hepatitis associated with aplastic anemia was reported by Lorenz in 1955. We observed a patient who developed acute hepatitis, associated with febrile purpura: pancytopenia was present, but not aplasia. This association is frequent in Flavivirus-related infections, like Dengue and Yellow Fever, and principally affects children and young people. HCV belongs to the Flavivirus family and so in this case clinical signs may have developed as a consequence of HCV infection.

[Isolated jejunal rupture after closed thoraco-abdominal trauma]

INTRODUCTION

Short bowel disruption following blunt abdominal trauma is rare and hard to diagnose and to treat. Death rate depends both on timing of surgical procedure and on associated lesions.

MATERIAL AND METHODS

We show a case of short bowel isolated lesion following fall from mountain bike, III degree in O.I.S. Classification. Abdominopelvic US and helicoidal CT scan were performed, reveling pneumoperitonaeum due to hollow viscus disruption. Surgical procedure was performed within five hours from trauma.

RESULTS

No complications occurred in postoperative period. Upper alimentary tract X-ray proved a regular transit, without any fistula. Patient was discharged on 13th day.

CONCLUSION

Laparotomy must not be delayed if there is any doubt about bowel conditions: it's demonstrated that timing of surgical procedure is related to prognosis. If haemodynamic status of the patient allows, careful abdomen CT evaluation is mandatory; adequate nutritional support in postoperative period is also very important.

[Stress urinary incontinence: an overview on actual surgical trends]

Stress urinary female incontinence (IUS) is an unpleasant symptom describing a loss of urine during physical exertion; genuine stress incontinence (GSI) is a socially unacceptable, involuntary loss of urine in absence of detrusor activity from the urethra associated with sudden cough or strain. The incidence of IUS is less than 10% in reproductive-age women but may approach 10-20% in postmenopausal women. The IUS pathophysiology is connected with two specific mechanisms: the urethral-bladder sliding out of anatomical area involves the normal system of endobladder/intraabdominal pressures, with a loss of urine; the second mechanism involves the damaged urethral sphincteric function, with a reduction of the urethral closure pressure and a urinary loss after minimal physical stimulation. The IUS medical therapy is troublesome and often inefficient, and the only approved effective measures are the surgical procedures, actually reserved for cases of unsuccessful medical therapy; surgical treatments can be classified according to the access as: vaginal, abdominal, associated and complex. They intend to reposition the urethral-bladder sliding in its normal intra-abdominal position, to allow equal transmission of increased intraabdominal pressure to the bladder and the proximal urethra. In the scientific literature there are more than one hundred surgical procedures for IUS correction, but the IUS surgical approach is anyway the actual gold standard therapy.
