Accidental insertion of double-J in the inferior vena cava in a patient with retroperitoneal fibrosis: a case report.

Background: Implantation of the double-J stent is a common procedure in urology. The function of this device is to maintain the flow of urine from the ureteropelvic junction to the urinary bladder when the ureter is blocked or partially blocked for some reason. Once in place, the stent may cause low back pain, hematuria, symptoms of urinary irritation, a reduction in labor capacity, infection and calcification which are side effects that are easy to manage. However, severe complications can occur, such as the insertion of the stent into the circulatory system, such as the vena cava, which, although uncommon, is one of the most severe and difficult to manage. This work reports the case of a patient with the accidental insertion of a double-J stent into the inferior vena cava. Case Description: An 80-year-old female patient with repeated urinary tract infections using a double-J stent due to stenosis of the right distal ureter distal presenting retroperitoneal fibrosis secondary to previous radiotherapy. The patient had Lynch syndrome, ovarian and uterine cancer, colorectal cancer, and nephrolithiasis. She had been submitted to multiple previous surgeries. Due to the possibility of viral infection by coronavirus disease 2019 (COVID-19), chest computed tomography was performed, which suggested the insertion of the double-J stent in the inferior vena cava, confirmed by abdominal computed tomography. As the distal end of the stent was within the bladder, the decision was made to remove the stent by cystoscopy, with the implantation of a new stent using fluoroscopic control for the confirmation of its trajectory. No intraoperative or postoperative complications occurred and the patient is currently in outpatient follow-up. Conclusions: Situations such as this require caution during the implantation of the drainage device, with the occurrence of resistance indicating the need to discontinue the procedure and perform a new assessment with imaging exams. No intraoperative or postoperative complications occurred and the patient is currently in outpatient follow-up.

Anxiety in candidates for radical prostatectomy in a university hospital.

OBJECTIVE: Metabolic changes caused by anxiety can interfere in both the surgery itself and the recovery process. One way to reassure the patient is to clarify how the procedure will be performed and discuss the possible complications. This study aimed to investigate the anxiety level of candidates for radical prostatectomy at a university hospital. METHODS: Thirty-four patients with a diagnosis of prostate cancer were studied prospectively. Data collection involved the administration of the Hospital Anxiety and Depression Scale and a radical prostatectomy knowledge test. RESULTS: The results showed that 94.1% of the patients reported having received clarifications from the physician or healthcare team regarding the surgery and 23.5% reported having received information on the probability of a medical error during surgery. The most cited postoperative complications were sexual impotence and urinary incontinence. A significant association was found between the total Hospital Anxiety and Depression Scale score and the complications cited (p=0.0004); patients who marked a larger number of possible complications had a higher Hospital Anxiety and Depression Scale score. CONCLUSION: The present study demonstrates that the explanations given by the multidisciplinary health team are not achieving their maximum potential in terms of lowering patient anxiety.

Sexual health education among undergraduate students of medicine.

BACKGROUND: Sexuality occupies a fundamental position in the lives of individuals and is related to general health. However, undergraduate curricula in medical courses address this topic in an incomplete manner. The aim of this study is to investigate sexual health education among undergraduate medical students. METHODS: A descriptive, cross-sectional study was conducted with students 18 years of age and older in the fifth and sixth years of the undergraduate course in medicine in 2018. Data were collected using a self-administered questionnaire addressing the teaching of sexual health in the first four years of the course and how knowledge on this topic affected their relationships with patients. RESULTS: A total of 125 students answered the questionnaire. Although the majority reported the teaching of sexual medicine during the undergraduate course, the classes were focused on reproduction (70%) and organic diseases (70%). A total of 52% of the respondents reported that the classes did not enhance their knowledge or confidence with regards to discussing the subject with patients. During routine care, the main difficulties the students faced in addressing the sexual health of patients were fear of offending the patient (53.8%) and insufficient knowledge on the subject (33.4%). CONCLUSIONS: The present findings demonstrate that knowledge of students regarding sexual health in undergraduate courses is insufficient, as evidenced by deficiencies in teaching and difficulties in addressing the subject with patients.

Anti-fibrotic effect of mycophenolate mofetil on Peyronie's disease experimentally induced with TGF-ß.

The aim of the present study was to evaluate the histological, histochemical, and stereological changes caused by mycophenolate mofetil (MMF) on the tunica albuginea of rat penises submitted to an injection of transforming growth factor beta (TGF-ß) for the induction of Peyronie's disease (PD). Twenty adult male Wistar rats were divided into four groups: Control group; TGF-ß group (TGF-ß injection); MMF-7d group (treated with MMF 7 days after induction with TGF-ß); and MMF-30d group (treated with MMF 30 days after induction with TGF-ß). The steorological evaluation included the relative volume of different types of connective fibres of the tunica albuginea. The histochemical analysis revealed the fragmentation and degradation of elastin in the tunica albuginea. This process was partially reversed in the MMF-7d group and a situation very close to normality was observed in the MMF-30d group. In the collagen III/collagen I ratio it was observed increase in this ratio in the TGF-ß (59.4 ± 5.53) and MMF-7d (49 ± 18.2) groups and a decrease in the MMF-30d group (28.7 ± 4), approaching normality. The injection of TGF-ß promoted fibrotic alterations in the penile tunica albuginea in Wistar rats corresponding to PD. In this model, MMF acts as a regenerating anti-fibrotic agent.

Is a differential diagnosis necessary in a patient with ureteritis cystica?

Ureteritis cystica is a rare urological disease with an undefined etiology. Despite the benign behavior, the differential diagnosis should be investigated, as other conditions the cause filling defects in the ureters may occur. We present a rare case of a patient with ureteritis cystica whose differential diagnosis was satisfactory.

Embolization in Patient with Hypovolemic Shock after Transobturator Sling Procedure.

The placement of a suburethral sling is standard treatment for stress urinary incontinence. The transobturator technique (TOT) emerged as an alternative to minimize the risks of the blind insertion of needles, leading to a lower rate of perforation complications compared with the retropubic approach. We present a case of injury to a branch of the left obturator artery following the placement of a urethral sling using TOT, followed by intense bleeding and hemodynamic instability, which was treated with embolization.

Sling de uretra média é o tratamento padrão para a incontinência urinária de esforço. A abordagem transobturatória (TOT) surgiu como alternativa para minimizar os riscos da inserção às cegas das agulhas com taxa de complicações perfurativas menores quando comparadas à abordagem retropúbica. Apresentamos um caso de lesão em ramo da artéria obturatória esquerda após sling TOT que evoluiu com sangramento intenso e instabilidade hemodinâmica, sendo tratado com embolização.

Does right-sided varicocele indicate a right-sided kidney tumor?

Varicocele is a dilation of the pampiniform venous plexus, mainly affecting the left side of the scrotum. In rare cases, however, the right side is affected. When this occurs, a retroperitoneal disease should be suspected, such as right-sided renal neoplasm. The present case report highlights the importance of right-sided varicocele in the diagnostic investigation of neoplasm of the right kidney.

Cake kidney drained though a single ureter in a patient with recurring urinary tract infection.

Cake kidney is a rare abnormality of the urinary tract. It is generally asymptomatic but can lead to renal and nonspecific systemic manifestations. This report describes a case of cake kidney drained through a single ureter diagnosed in a female patient with recurring urinary infection.

Spermatic cord paratesticular tumor: a rare case report.

Paratesticular tumors account for 5% of tumors originating in the scrotum. Angiomyofibroblastoma-like tumor is a rare benign mesenchymal soft tissue tumor found in the genital region in both sexes and is even rarer in the spermatic cord. The origin of this tumor remains the object of speculation, but it is believed to originate from perivascular mesenchymal cells. The purpose of the present case report is to expand knowledge on the histology of this rare paratesticular tumor.

Incidental finding of retrocaval ureter in a patient without hydronephrosis.

Retrocaval or circuncaval ureters are rare congenital anomaly, in which the ureter is located posterior to the inferior vena cava (IVC). Usually, patients present symptoms in the 3rd or 4th decade of life due to compression of the ureter by the IVC, with obstruction of the urinary flow and consequent hydronephrosis. Herein we report the case of a 62-year-old patient who underwent ultrasonography to investigate abdominal pain. The patient had bilateral renal lithiasis associated with urinary tract dilation with no obvious obstruction. Computed tomography of the abdomen demonstrated a retrocaval ureter without hydronephrosis.

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.

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. METHODS: Seventy-seven patients submitted to nephrectomy for benign and malignant diseases in a university hospital were evaluated in respect to preoperative and postoperative creatinine clearance. Demographic (gender, age), clinical (cancer, diabetes, high blood pressure, chronic kidney disease) and surgical (anesthesia time, open or laparoscopic surgery) variables were also analyzed. RESULTS: Of the 77 patients, 72 met the inclusion criteria. Of these, ten (13.8%) had a diagnosis of chronic renal failure (CRF), 30 (48%) had stage I ARF and one (16.1%) had stage II ARF. The anesthesia time, type of surgery (open or laparoscopy), total or partial nephrectomy, the side of the procedure, hypertension, diabetes, CRF, renal cancer, preoperative and postoperative creatinine concentrations were analyzed. Only the difference between preoperative and postoperative creatinine clearance was clinically significant (P<0.001). CONCLUSIONS: An altered preoperative renal function is a risk factor for the development of ARF in nephrectomized patients.

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. The ages of the patients ranged from 19 to 88 years old (mean: 59.82 ± 10.48 years). The only exclusion criterion was the amputation of one or both legs. The ankle-arm index was assessed and the international index of ED questionnaire was applied to all participants in the study. RESULTS: Of the 125 patients, 22 (17.6%) had mild (grade 1), 50 (40.0%) had moderate (grade 2) and 53 (42.4%) had severe (grade 3) ED. Hypertensive patients have more ED, with ED in hypertensive patients being associated to chronic arterial disease. However, in comparison with normotensive patients, hypertension exerts an immediate protective effect on erectile function. CONCLUSIONS: In conclusion, although erectile function is initially protected by systemic arterial hypertension in patients with chronic arterial disease, both chronic arterial disease and ED deteriorate over the long term in hypertensive patients.

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.
