Colovesical Fistula in a Kidney Transplant Patient: A Fatal Outcome.

Colovesical fistula (CVF) is a rare but potentially serious condition characterized by abnormal communication between the colon and the bladder. This pathology can result from inflammatory diseases, malignancies, or previous surgical interventions, with a significant impact on the patient's quality of life. CVF is associated with high morbidity and mortality rates, particularly in immunosuppressed individuals, such as renal transplant recipients, due to their increased susceptibility to infections and surgical complications.

Combined Percutaneous and Endoscopic Ureterolithotripsy of Calcified Double J Stent.

In urological practice, the routine procedure of placing a double J stent aims to facilitate drainage of the upper urinary system. Despite its temporary nature and the necessity for timely removal, approximately 12% of these stents are retained in patients for extended durations due to various reasons. Forgotten ureteral stents can lead to complications that increase the morbidity and mortality of patients.

Public contracting of home respiratory care services through an electronic quasi-market model.

Respiratory diseases are becoming a major challenge in health systems as they cover expanding and diversified pathologies such as chronic obstructive pulmonary disease, chronic bronchitis, emphysema and other types increasing at a fast rate as it is the case of sleep apnoea. Nowadays, most of these pathologies can be treated by home respiratory care services using advanced medical equipment as well as efficient assistance and monitoring services supported by digital technologies. However, the implementation of home respiratory care services implies flexible public contracting of such services to achieve equity conditions of access and to cope with their technological nature, their continuous processes of innovation and their time dependent demand.

Partial Nephrectomy of Transplanted Kidney with Calyceal Fistula.

Kidney transplant is the established treatment for patients with chronic kidney disease but is associated with complications due to the complexity of the procedure. Calyceal fistulas are rare urological complications in transplants caused by arterial occlusion with segmental infarction of the graft. Treatment is based on the extension of the affected area and the clinical status of the patient.

Knee MR Using a Body Coil is Equivalent to CT in Measuring the TT-TG Distance: Removing the Systematic Bias.

 To compare magnetic resonance imaging (MRI) using a body coil with computed tomography (CT) in measuring the tibial tubercle-trochlear groove distance (TT-TG) and the patellar tendon-cartilaginous trochlear groove (PT-CTG) distances, and evaluate interrater reliability.  The study group consisted of 34 knees from 17 asymptomatic subjects with no history of knee pathology, trauma or surgery. A low-dose CT scan and an axial T1-weighted MRI sequence of the knees were performed with rigorous standardization of the positioning with full extension of the knees and parallel feet.

Anatomical variations and congenital anomalies of the ribs revisited by multidetector computed tomography.

As they are asymptomatic or have a nonspecific, anatomical variations of the ribs are usually detected as incidental findings on imaging studies. They may be isolated changes or can be related to anomalies or clinical syndromes. Such variations are easily overlooked on conventional radiography and computed tomography if they are not actively investigated, mainly because most indications for a chest X-ray studies aim to evaluate the lung parenchyma and mediastinal structures.

Inguinal hernia with ureter in patient with single kidney.

Inguinal hernias are a common disease in adults, but involvement of extraperitoneal structures is rare. This condition is usually asymptomatic and an incidental finding during the surgical correction of inguinal hernias, often resulting in iatrogenic damage. We present a rare case of left renal agenesis and right inguinal hernia, with the ureter being the only organ protruding as an inguinal hernia, diagnosed in the preoperative period.

Is hypogonadism the cause of penile self-amputation in a patient with prior testes self-mutilation?

Introduction: This paper presents a rare event of genital self-mutilation and few cases are reported in the literature.

Case Description: We report on a patient who performed partial self-penectomy 18 months after bilateral testicular amputation, as a form of self-mutilation.

Conclusions: The main hypotheses to explain the recurrence of self-mutilation would be hypogonadism.

Risk factors for acute renal failure in nephrectomized patients treated in a university hospital.

Background: New surgical techniques for nephrectomy mainly related to early diagnosis made possible by advances in imaging studies have been developed in recent decades. However, postoperative renal dysfunction is a constant concern because of the major problems faced by healthcare services and by the patients themselves. To assess risk factors for developing acute renal failure (ARF) in patients submitted to nephrectomy in a university hospital.

Association of Hypertension With Erectile Function in Chronic Peripheral Arterial Insufficiency Patients.

Background: Risk factors may influence the improvement or worsening of erectile dysfunction (ED). The aim of the current study was to evaluate the effect of systemic hypertension on ED in patients with peripheral arterial disease.

Methods: The effect of hypertension on ED was assessed in 125 consecutive patients in a cross-sectional quantitative study.

Incidental Diagnosis of Nonfunctional Bladder Paraganglioma.

Nonfunctional bladder paragangliomas may present clinical, radiology and pathological features similar to bladder cancer, so knowledge of this generally benign neuroendocrine neoplasm is of great importance to avoid misdiagnosis. We present the case of a patient with no clinical symptoms of paraganglioma and with radiological and cystoscopy examination results suggestive of urothelial carcinoma but with pathological diagnosis of paraganglioma.

Penile Replantation After Five Hours of Warm Ischemia.

Although a rare occurrence, this event may occur as a result of self-mutilation among individuals with psychiatric disturbances or due to work-related accidents, iatrogenic injuries or the actions of individuals motivated by jealously, rage and feelings of betrayal. In western societies, most penile amputations are the result of self-aggression during a psychotic episode, the treatment of victims involves resuscitation, stabilization and immediate psychiatric support. The amputated tissue must be preserved under hypothermic conditions.

Familial mixed nephrocalcinosis as a cause of chronic kidney failure: two case reports.

Introduction: Nephrocalcinosis consists of the deposition of calcium salts in the renal parenchyma and is considered the mixed form when it involves the renal cortex and medulla. The main etiological agents of this condition are primary hyperparathyroidism, renal tubular acidosis, medullary sponge kidney, hyperoxaluria and taking certain drugs. These factors can lead to hypercalcemia and/or hypercalciuria, which can give rise to nephrocalcinosis.

Nonalcoholic steatohepatitis on preoperative period of gastric bypass: lack of correlation with degree of obesity.

Background: Metabolic disorders have high correlation with severe forms of nonalcoholic fatty liver disease. However, there is no non-invasive method that promotes its proper stratification and biopsy remains the ideal diagnostic tool.

Aim: To evaluate the prevalence of this disease in obese in preoperative period of Roux-en-Y gastric bypass and metabolic factors correlated with liver histopathology.

Prostatic paracoccidioidomycosis with a fatal outcome: a case report.

Introduction: Paracoccidioidomycosis is a systemic mycosis in Latin America that can affect various organs. Few case reports of paracoccidioidomycosis affecting the prostate are found in the literature.
