BACKGROUND: Low mean arterial pressure (MAP) is a well-known risk factor for postoperative acute kidney injury (AKI), but probably it is not the sole hemodynamic parameter that can influence the development of renal failure. There are data in cardiac patients supporting the role of renal venous congestion in the development of AKI. The aim of our study was to determine a combination of factors best predicting the development of AKI. METHODS: Data were collected prospectively for adult patients admitted after major abdominal surgery to 9 Hungarian intensive care units...

The male pelvic floor muscles comprise a pair of compound muscle layers referred to as the levator ani. Studies have shown that pelvic floor muscle strength is affected by physical activity. This study aimed to assess male pelvic floor muscle strength through manometry of the external anal sphincter and evaluation of its association with physical activity level, BMI, and rectal pressure in healthy men. To assess physical activity level over the previous week, we used the International Physical Activity Questionnaire 8 (IPAQ)...

INTRODUCTION: Appropriate mechanical ventilation and prevention of alveolar collaps is mainly dependent on transpulmonary pressure TPP. TPP is assessed by measurement of esophageal pressure EP, largely influenced by pleural and intraabdominal pressure IAP. Consecutively, TPP-guided ventilation might be particularly useful in patients with high IAP. This study investigates the impact of large volume paracentesis LVP on TPP, EP, IAP as well as on hemodynamic and respiratory function in patients with liver cirrhosis and tense ascites...

The influence of intraabdominal pressure which is necessary to maintain the operating area during the surgery cannot be ignored especially on the kidneys. Many articles have reported the effect of intraabdominal pressure on normal kidneys. However, the influence of intraabdominal pressure on hydronephrosis kidneys is rarely studied. The aim of the present study was to clarify whether intraabdominal pressure tolerance is modified in various degrees of kidney hydronephrosis by evaluating oxidative damage and mitochondrial injuries...

The differential diagnosis of anuria in emergency department (ED) is broad. Secondary to intraabdominal mass pressure or infections, symptoms of micturation difficulties or disuria accompanying to back pain may arise with the interruption of sacral nerve stimulation. Here, we report a patient who admitted to ED with back pain and anuria and diagnosed acute appendicitis (AA) after advanced investigation despite of not to have any abdominal pain. A 36-year-old man admitted to our ED with a 6-h history of back pain and urination difficulty...

BACKGROUND: Hydrocolpos and hydrometrocolpos are rare malformations caused by accumulation of secretion due to congenital obstruction of the vagina. Hydro(metro)colpos may be isolated or can be combined with other malformations as part of a syndromic disorder. We report on a series of 20 cases with hydro(metro)colpos diagnosed prenatally, delineate the differential diagnoses, and illustrate the spectrum of associated malformations. SUBJECTS AND METHODS: This was a retrospective study involving 20 fetuses with hydro(metro)colpos at two large tertiary referral centers in Germany over an 18-year period (2000-2017)...

Midurethral mesh sling is the most performed incontinence procedure. This hypotheses propose knotless barbed suture could be positioned as a tension-free trans-vaginal sling under the mid-urethra without vaginal incision. Knotless suture sling support and stabilize mid-urethra when intraabdominal pressure increase. This procedure is designed to replace midurethral mesh sling operation, aiming at reducing complications. It is completed in a similar way with retropubic mesh sling procedure, and less invasive...

BACKGROUND: A mechanical intestinal obstruction (MIO) can generate intraabdominal hypertension (IAH) that is life threatening. The intestines are very sensitive to IAH since the low splanchnic perfusion causes intestinal hypoxia, local acidosis and bacterial translocations. This may lead to acute intestinal distress syndrome (AIDS). The identification of intestinal injuries during IAH and its correlation with clinical parameters as the abdominal perfusion pressure (APP), the gastric intramucosal pH (pHi) and lactic acid (Lc) are still unknown...

Risk of optic nerve injury after prolonged Trendelenburg's position Postoperative loss of vision due to acute ischaemic optic nerve injury is a rare complication following pelvic surgery. A steep Trendelenburg's position of the patient, high intraabdominal pressure and a long operative time in Trendelenburg's position are recognised risk factors associated with robot-assisted pelvic surgery. This manuscript presents the underlying pathophysiologic mechanism. Practical tips and tricks for prevention are discussed...

OBJECTIVE The gold standard for evaluation of ventriculoperitoneal (VP) shunt position, dislocation, or disconnection is conventional radiography. Yet, assessment with this modality can be challenging because of low image quality and can result in repetitive radiation exposure with high fluctuation in the radiation dose. Recently, CT-based radiation doses have been significantly reduced by using low-dose protocols. Thus, whole-body low-dose CT (LDCT) has become applicable for routine use in VP shunt evaluation...

BACKGROUND: Hyperthermic intraperitoneal chemotherapy (HIPEC) following cytoreductive surgery (CRS), performed using closed-abdomen technique (CAT), may affect intraabdominal pressure (IAP). High IAP may increase postoperative complications due to decreased venous return and hypoperfusion to vital organs. Elevated core body temperature (CBT) may cause multiorgan dysfunction. Low IAP or CBT could result in suboptimal HIPEC and potentially translate into early disease recurrence. The aim of the present study is to identify possible correlations between IAP or CBT and postoperative complications...

Although hysteroscopy is currently the undisputed gold standard for the examination of the uterine cavity in women with suspected endometrial cancer, it remains controversial as a procedure that can enhance metastasis spread. Endometrial cancer cells may shed during hysteroscopy and be passively transported with fluid flow into the peritoneal cavity. The paper presents the review of current knowledge regarding the risk of neoplasm metastases in women who had diagnostic hysteroscopy and the conditions that have to be met for the procedure to be safe...

BACKGROUND: Tracheal tube cuff pressures exceeding the perfusion pressures of the tracheal mucosa have been associated with complications such as sore throat, tracheal mucosa ulcers, tracheal rupture, and subglottic stenosis. Despite appropriate inflation, many factors can increase the tracheal cuff pressure during mechanical ventilation. This prospective observational cohort study was designed to test the hypothesis that during a clinical model of decreasing respiratory compliance, the pressure within the endotracheal tube cuff will rise in direct relationship to increases in the airway pressures...

In the surgical management of large incisional hernias, the main target is the closure of the abdominal wall defect on the midline without a dangerous increase in the intraabdominal pressure. In this setting, new intraperitoneal prosthesis and components separation techniques were proposed to solve this problem. Both solutions present some critical issues. A new surgical approach with a free lateral double layer prosthesis totally in polypropylene both sides (FLaPp® ) is proposed to overcome this problem. This is a retrospective cohort analysis study with a prospectively collected database from two different Italian hospitals...

BACKGROUND: The etiology of inguinal hernias remains uncertain even though the lifetime risk of developing an inguinal hernia is 27% for men and 3% for women. The aim was to summarize the evidence on hernia etiology, with focus on differences between lateral and medial hernias. RESULTS: Lateral and medial hernias seem to have common as well as different etiologies. A patent processus vaginalis and increased cumulative mechanical exposure are risk factors for lateral hernias...

Idiopathic intracranial hypertension (IIH), formerly known as pseudotumor cerebri, is a disease of elevated intracranial pressure that is thought to develop due to impaired CSF absorption related to elevated venous sinus pressure in the setting of increased intraabdominal and thoracic pressures. Symptoms can be disabling and, if left untreated, can lead to permanent visual loss. Previous treatments directed toward vision preservation include CSF diversion through shunting and optic nerve sheath fenestration...
