OBJECTIVE: Urinary lithiasis is a common disease. The aim of the present study is to assess the knowledge regarding the diagnosis, treatment and recommendations given to patients with ureteral colic by professionals of an academic hospital. MATERIALS AND METHODS: Sixty-five physicians were interviewed about previous experience with guidelines regarding ureteral colic and how they manage patients with ureteral colic in regards to diagnosis, treatment and the information provided to the patients. RESULTS: Thirty-six percent of the interviewed physicians were surgeons, and 64% were clinicians. Forty-one percent of the physicians reported experience with ureterolithiasis guidelines. Seventy-two percent indicated that they use noncontrast CT scans for the diagnosis of lithiasis. All of the respondents prescribe hydration, primarily for the improvement of stone elimination (39.3%). The average number of drugs used was 3.5. The combination of nonsteroidal anti-inflammatory drugs and opioids was reported by 54% of the physicians (i. e., 59% of surgeons and 25.6% of clinicians used this combination of drugs) (p = 0.014). Only 21.3% prescribe alpha blockers. CONCLUSION: Reported experience with guidelines had little impact on several habitual practices. For example...

Mais do que uma realidade na clínica de felinos, os cálculos renais em gatos tornaram-se motivo de grande preocupação para a especialidade. Em contraste aos cálculos de estruvita encontrados frequentemente na vesícula urinária, os cálculos de oxalato de cálcio (CaOx), localizados em rins e ou ureteres passaram a compor um novo perfil da urolitíase. Foi realizado um estudo clínico transversal com 96 gatos com o objetivo de determinar a ocorrência de cálculos de origem renal (nefrolitíase e ureterolitíase) em gatos portadores de DRC e uma possível associação entre essas duas doenças. Destes pacientes, 24 foram excluídos por não atenderem os critérios necessários para classificação entre os grupos. Assim, 72 gatos portadores de DRC foram divididos em dois grupos, DRC com evidências de nefrolitíase e ou ureterolitíase (n=47), e DRC sem evidências de nefrolitíase e ou ureterolitíase (n=25). Os grupos mostraram homogeneidade em relação à classificação da DRC segundo os estágios propostos pela IRIS - International Renal Interest Society (p= 0,5613), como também em relação à idade (p=0,274). Contudo, os gatos classificados no estágio II da DRC foram os mais representados em ambos os grupos. Apesar disso...

CONTEXT AND OBJECTIVE: Recent studies have shown noncontrast computed tomography (NCT) to be more effective than ultrasound (US) for imaging acute ureterolithiasis. However, to our knowledge, there are few studies directly comparing these techniques in an emergency teaching hospital setting. The objectives of this study were to compare the diagnostic accuracy of US and NCT performed by senior radiology residents for diagnosing acute ureterolithiasis; and to assess interobserver agreement on tomography interpretations by residents and experienced abdominal radiologists. DESIGN AND SETTING: Prospective study of 52 consecutive patients, who underwent both US and NCT within an interval of eight hours, at Hospital São Paulo. METHODS: US scans were performed by senior residents and read by experienced radiologists. NCT scan images were read by senior residents, and subsequently by three abdominal radiologists. The interobserver variability was assessed using the kappa statistic. RESULTS: Ureteral calculi were found in 40 out of 52 patients (77%). US presented sensitivity of 22% and specificity of 100%. When collecting system dilatation was associated, US demonstrated 73% sensitivity, 82% specificity. The interobserver agreement in NCT analysis was very high with regard to identification of calculi...

We report a case of a 32-year-old man, who presented to the emergency department with severe abdominal pain, with radiation to his back. An ultrasound examination revealed mild hydronephrosis bilaterally. A non-enhanced computer tomography was then performed and showed a 9 mm hyperdense image in the left ureter topography along together with an 8-mm hyperdense image in the right ureter topography, allowing us to establish the diagnosis of bilateral ureterolithiasis. The patient was taken to the operating room in order to perform ureteroscopy for endoscopic removal of the stones.

Retrocaval ureter is a rare cause of hydronephrosis. Its rarity and non-specific presentation pose a challenge to surgeons and radiologists in making the correct diagnosis. Differentiation from other causes of urinary tract obstruction, especially the more common urolithiasis, is important for successful surgical management. Current practice has seen multislice computed tomography (MSCT) rapidly replaces intravenous urography (IVU) in the assessment of patients with hydronephrosis due to suspected urolithiasis, especially ureterolithiasis. However, MSCT, without adequate opacification of the entire ureter, may allow the physician to overlook a retrocaval ureter as the cause of hydronephrosis. High-resolution IVU images can demonstrate the typical appearance that leads to the accurate diagnosis of a retrocaval ureter. We reported a case that illustrates this scenario and highlights the importance of IVU in the assessment of a complex congenital disorder involving the urinary tract.

The differential diagnosis of right lower quadrant abdominal pain includes both ureterolithiasis and acute appendicitis. Surgical treatment can be undergone without confirmatory imaging studies after a clinical diagnosis is made. For this reason, an occult, second abdominal process may be present.

We report a case of metastatic bladder cancer developing in a young man with cystic fibrosis (CF) that was initially diagnosed as ureterolithiasis and managed as renal colic. With the improved survival of patients with CF, an increasing burden of extrapulmonary disease manifestations is apparent. Renal colic is observed at an increased frequency in patients with CF relative to the general population and is a commonly recognized cause of hematuria. However, CF patients harboring a malignancy are recognized to be at increased risk of delayed identification owing to atypical symptoms and lack of demographic risk factors. This case illustrates how investigations to rule out malignancy are warranted in those CF patients not responding to therapies directed towards presumptive diagnoses.

Dissertação de Mestrado Integrado em Medicina Veterinária; A nefroureterolitíase evidenciou-se nos últimos 20 anos como uma importante causa de doença renal aguda e crónica. A principal indicação para remoção destes urólitos no gato é a presença de obstrução ureteral. Contudo, os procedimentos cirúrgicos tradicionais estão normalmente associados a altas taxas de morbilidade e mortalidade. Os recentes avanços nas técnicas endourológicas interventivas têm permitido uma melhor gestão desta patologia. Este estudo retrospetivo procurou caracterizar do ponto de vista clínico e epidemiológico os casos de nefroureterolitíase em gatos acompanhados no Hospital Escolar da VetAgro Sup (Lyon, França) entre Janeiro de 2008 e Junho de 2012 e ainda avaliar a técnica de nefroscopia associada à hidropropulsão ureteral retrógrada na remoção da litíase do trato urinário superior. A amostra de felinos em estudo (n=31) foi composta maioritariamente por gatos de raça doméstica (68%), de ambos os géneros, esterilizados (87%), com uma idade média de 5,3 anos, que vivem exclusivamente no interior (67%) e cuja alimentação, exclusivamente à base de granulado, é adquirida sobretudo no veterinário (71%). Os sinais clínicos apresentados foram maioritariamente inespecíficos...
