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.

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.

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.

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.

Case Presentation: We present the case of a 79-year-old Caucasian man with a six-month history of irritative symptoms of the prostate (urgency, frequency and nocturia) and difficulty initiating urination that progressed to urinary retention and the use of a urinary catheter.

Quantification of fractal dimension and Shannon's entropy in histological diagnosis of prostate cancer.

Background: Prostate cancer is a serious public health problem that affects quality of life and has a significant mortality rate. The aim of the present study was to quantify the fractal dimension and Shannon's entropy in the histological diagnosis of prostate cancer.

Methods: Thirty-four patients with prostate cancer aged 50 to 75 years having been submitted to radical prostatectomy participated in the study.
