[Renal colic]. / Steinkolik.

INTRODUCTION: Renal colic accounts for 5-10% of all emergency department visits, making it a common condition in acute medicine. The typical clinical presentation is an early indication of urolithiasis. DIAGNOSIS: Diagnostic measures include laboratory tests, ultrasound, and low-dose noncontrast computed tomography (CT) scans. Kidney, ureter, bladder (KUB) plain film radiography has been widely replaced by low-dose noncontrast CT with similar radiation dosage. In special patient groups such as children or pregnant women, ionizing radiation should be avoided if possible. TREATMENT: General measures involve pain management (non-steroidal anti-inflammatory agents, opioids) and empirical antibiotic treatment for suspected bacterial infection. Depending on the location/size of the stone, pharmacological stone expulsion therapy may be considered. In cases of obstructive pyelonephritis or acute renal insufficiency, early urinary drainage (JJ stent/nephrostomy) is recommended. Definitive stone removal may be performed primarily in some cases (rather small and rather distal ureterolithiasis). It is common to schedule stone removal as a secondary intervention.

Urologic Presentation of Unicentric Pediatric Castleman Disease in the Setting of Acute Renal Colic.

An 11-year-old otherwise healthy female presented with renal colic and during computed tomography imaging evaluation, she was found to have a right distal ureteral stone with associated hydroureteronephrosis, medially deviated ureter, and 4-cm solid retroperitoneal mass. The mass was palpable on physical exam and was further categorized with magnetic resonance imaging, ultrasound, and laboratory testing. A multidisciplinary team approach, including pediatric surgery, radiology, oncology, and urology, led to the patient undergoing a right retrograde pyelogram, ureteroscopy with stent placement, and laparoscopic excision of retroperitoneal mass. Her pathology revealed lymphoid hyperplasia with histologic features of Castleman disease.

Preference for diagnosing and treating renal colic during pregnancy: a survey among Chinese urologists.

To explore the preference for diagnosing and treating renal colic during pregnancy among Chinese urologists. A questionnaire was designed using the Sojump® platform. WeChat, the largest social networking platform in China, was used to distribute the questionnaire to urologists at hospitals of all levels in China. In total, 110 responses were included. Of the respondents, 100.0% used ultrasound to diagnose renal colic during pregnancy, followed by magnetic resonance imaging (17.3%) and low-dose CT (3.6%). Phloroglucinol (80.9%) and progesterone (72.7%) were the most commonly used antispasmodics and analgesics. Opioid analgesics were not commonly used (12.7%). Most of the respondents (63.6%) indicated that no more than 20% of the patients needed surgical intervention. If surgery was unavoidable, 95.5% preferred temporary renal drainage, including ureteral stenting (92.7%) and percutaneous nephrostomy (2.7%). However, some respondents still preferred definitive stone treatment, such as ureteroscopy lithotripsy (3.6%) and percutaneous nephrolithotomy (0.9%). Moreover, there were no differences in the choices of urologists with different professional titles regarding diagnostic tools, most therapeutic medications, or surgical methods (p > 0.05). Ultrasound is the preferred tool for diagnosing renal colic during pregnancy. Low-dose CT is still not widely accepted. Pregnant patients with renal colic are initially treated conservatively. Urologists prefer ureteral stenting when there are clinical indications for intervention.

[Not all low back pain is renal colic]. / No todo dolor lumbar es un cólico nefrítico.

Low back pain is one of the most frequent reasons for consultation in primary care. Sometimes it is not easy to make a good differential diagnosis, because the number of pathologies that can express themselves with such symptoms is very wide and a complementary test or referral to the reference hospital is not always indicated. The following is a clinical case of a 59-year-old female patient with a history of dyslipidemia treated with ezetimibe, who consulted again for breakthrough low back pain, which was finally diagnosed as a penetrating ulcer of the abdominal aorta, treated endovascularly by the vascular surgery service. The clinical case aims to provide an overview of the acute treatment of aortic syndrome, showing the differences compared to the management of other common pathologies in primary care with the same clinical expression.

Risk factors of uterine contraction after ureteroscopy in pregnant women with renal colic.

BACKGROUND: Ureteroscopy is widely applied in pregnant women with renal colic, but such patients are easy to experience uterine contraction after surgery. There are many factors which may affect uterine contraction, this study aims to explore the risk factors of uterine contraction triggered by ureteroscopy in pregnant women with renal colic. METHODS: One hundred and one pregnant women were retrospectively analyzed, the patients were hospitalized because of severe renal colic. All patients received ureteroscopy during which double J catheters were inserted into ureters for drainage. Patients received other medical treatments individually according to their condition and uterine contractions were detected by EHG within 12 h after operation. Patients were classified as group A (uterine contraction) and group B (no uterine contraction) according to the presence or absence of continuously regular uterine contraction. Clinical characteristics were collected for further analysis, including history of childbirth, anesthesia method, application of phloroglucinol or not, operation time, Oxygen inhalation or not, pain relief or not after surgery, systemic inflammatory response syndrome (SIRS) occurred or not. A binary logistic regression analysis model was established to explore whether such clinical characteristics were relevant to uterine contraction after ureteroscopy. RESULTS: Continuously regular uterine contraction presented in 46 pregnant women within 12 h after ureteroscopy, making the incidence of uterine contraction as high as 45.54%. The presence of uterine contraction was related to the following factors(P < 0.05): history of childbirth (primipara versus multipara)(OR 6.593, 95% CI 2.231-19.490), operation time (each quarter additional) (OR 2.385, 95% CI 1.342-4.238), application of phloroglucinol (yes versus not) (OR 6.959, 95% CI 1.416-34.194), pain relief after surgery(yes versus not)(OR 6.707, 95% CI 1.978-22.738), SIRS occurred after surgery (yes versus not) (OR 0.099, 95% CI 0.014-0.713). CONCLUSION: Continuously regular uterine contraction is easy to occur within 12 h after ureteroscopy in pregnant women. SIRS occurred after surgery is a risk factor for uterine contraction; on the contrary, no history of childbirth, shorter operation time, application of phloroglucinol, pain relief after surgery are protective factors.

A Diagnostic Score for Reliable Confirmation of Acute Renal Colic Among Patients With Acute Abdominal Pain.

BACKGROUND/AIM: Diagnostic scores (DSs) for confirmation of acute renal colic (ARCO) have rarely been evaluated. PATIENTS AND METHODS: A cohort of 1,333 patients with acute abdominal pain (AAP) were studied, including 59 patients with confirmed ARCO. The most significant diagnostic findings (in multivariate logistic regression analysis) were used to construct DS formulas for the diagnosis of ARCO. Meta-analytical techniques were used to detect the summary sensitivity and specificity estimates for each data set (clinical symptoms, signs and tests, as well as DS formulas). RESULTS: In hierarchical summary receiver operating characteristic analysis (HSROC), the values for area under the curve (95% confidence interval) for i) clinical symptoms ii) signs and tests, and iii) DS were 0.650 (0.612-0.688), 0.724 (0.680-0.768) and 0.962 (0.940-0.984), respectively. In HSROC analysis of the area under the curve values, differences were significant between i) and iii) (p<0.0001) and between ii) and iii) (p<0.0001). CONCLUSION: The present study is the first to provide evidence suggesting that the DS can be used for clinical confirmation of ARCO in patients with AAP, with a high diagnostic accuracy without radiological or laboratory analyses.

The efficacy of hemogram parameters in the differential diagnosis of renal colic and acute appendicitis in the emergency department.

BACKGROUND: To investigate the efficacy of WBC, PLR and NLR for use in the differential diagnosis of acute appendicitis and renal colic in the emergency department. METHODS: This study was conducted after consent was received from the Cukurova University Medicine Faculty Noninvasive Clinical Research Ethics Committee. In this study, 440 patients for whom file data could be accessed in the hospital automation and archive system who were admitted to the hospital with abdominal pain were included. RESULTS: Of the 440 patients included in this study, 59.5% were male and 40.5% were female. The average age of the patients was 37.74±13.39 years. According to the pathological diagnosis, 207 patients were diagnosed with acute appendicitis. When the efficacy of differential diagnosis using hematological parameters was examined with ROC analysis, the neutrophil/lymphocyte ratio (NLR) value had the strongest predictive ability (AUC, 0.716, SS=0.024, 95% GA 0.668-0.764). After NLR, the platelet/lymphocyte ratio (PLR) value was the second-best concerning predictive ability for differential diagnosis (AUC, 0.608 SS=0.027, 95%, GA 0.555-0.661). CONCLUSION: Patients with acute appendicitis and renal colic often present to the emergency department with abdominal pain. While patients with acute appendicitis are usually treated with surgical methods, medical treatment is used for renal colic in the acute period. The differential diagnosis of these two patient groups is important. We believe that the PLR and NLR values can be used when an exact differential diagnosis cannot be made.

Derivation of a clinical predicting rule for obstructive urolithiasis and alternative diagnosis requiring urgent intervention: the CLAD score.

Most patients with renal colic are discharged from the emergency department (ED) after evaluation and pain alleviation. These patients may not require urgent imaging by computed tomography. We derived a clinical prediction score in patients with renal colic to identify those at very low risk for complications and alternative diagnoses requiring urgent intervention. This retrospective chart review was carried out in 2 ED at an urban university hospital from January to December 2015. All patients with a diagnosis of renal colic were included. The primary outcome was an intervention required for renal colic or alternative diagnoses within 7 days of ED presentation. A stepwise logistic regression was used to assess factors associated with the outcome. A score was derived as a weighted sum of these predictors and its performance was calculated. The database was submitted to the French National Commission for Data Protection and Liberties (CNIL): declaration n°2164898v0 (03/22/2018). 871 with complete data were analyzed. In 94 (11%) patients, an intervention was performed for obstructive urolithiasis or alternative diagnosis. Five factors were most predictive of intervention: age > 45 years (1 point), a history of urologic surgery (1 point), pulse > 100 bpm (1 point), temperature > 37.8 °C (2 point), and urine dipstick negative for blood (1 point), yielding a score of 0-6 points (the Complicated uroLithiasis and Alternative Diagnosis (CLAD) score). The area under the curve of the receiver operating characteristic curve was 0.82 (95% CI 0.77-0.87). We derived a clinical score for renal colic that predicted the presence of obstructive urolithiasis and acute alternative diagnoses requiring intervention.

Hospitalización en paciente con cólico renal: Caracterización clínico-epidemiológica en el Hospital Clínico Herminda Martín, período marzo 2014 - marzo 2019 / Hospitalization in a patient with renal colic: Clinical-epidemiological characterization at the Herminda Martín Clinical Hospital, period March 2014 - March 2019

INTRODUCCIÓN: El cólico renal es una condición médica común en los servicios de urgencia. Representa la manifestación clínica más frecuente de urolitiasis, cuya patogenia es multifactorial, con tasas de prevalencia varía de 1% a 20% y una recurrencia a 10 años del 42% al 50%. OBJETIVO: Establecer el perfil clínico-epidemiológico, como también el diagnóstico y manejo de los pacientes hospitalizados por cólico renal en el Hospital Clínico Herminda Martín (HCHCM). MATERIAL Y MÉTODO: Estudio descriptivo retrospectivo en pacientes hospitalizados con diagnóstico de cólico renal en el HCHM de Chillán en el período marzo 2014-marzo 2019. Se estudiaron las variables: sexo, edad, presentación clínica de ingreso, factores de riesgo asociados, motivo de hospitalización, resultados imagenológicos y manejo clínico. Resultados. El 52,45% correspondió a pacientes de sexo masculino, encontrándose la mayor cantidad de pacientes en el intervalo de 40-49 años. La obesidad, antecedente de urolitiasis e hipertensión arterial fueron las patologías asociadas más frecuentes. En la mayoría de los pacientes, el motivo de la hospitalización fue la refractariedad al tratamiento analgésico, alcanzando un 86,76%. El 56,37% de los pacientes recibió manejo médico expulsivo y a un 19,11% de los pacientes se le realizó una intervención quirúrgica durante la hospitalización. CONCLUSIÓN: El perfil de éstos pacientes no sólo permite establecer medidas que podrían evitar un evento litiásico, sino que además se demuestra la necesidad de realizar un manejo óptimo que puede evitar reconsultas, sobrecarga de los servicios de urgencia, aumento de días cama y complicaciones.

INTRODUCTION: Renal colic is a common condition in the emergency department. It represents the most frequent clinical manifestation of urolithiasis, whose prevalence rate varies between 1% to 20%. Its pathogenesis is multifactorial, with a recurrence of 10 years from 42-50%. OBJECTIVE: Establish the clinical-epidemiological profile, as well as the diagnosis and management of patients hospitalized for renal colic at the Herminda Martín Clinical Hospital(HCHM). MATERIALS AND METHODS: A retrospective descriptive study of hospitalized patients diagnosed with renal colic at the HCHM, March 2014-March 2019, the variables were studied: sex, age, the clinical presentation of admission, associated risk factors, the reason for hospitalization, imaging results, and management. Results: 52.45% were male patients, with the highest number of patients in the range of 40-49 years. Obesity, a history of urolithiasis and hypertension, occurred more frequently within the associated pathologies. In most patients, refractable to analgesic treatment was the reason for hospitalization, reaching 86.76%. 56.37% of patients received expulsion medical management, and 19.11% of patientshad surgeryduring hospitalization. CONCLUSION: The profile of these patients not only allows them to establish measures that could prevent a lithiasis event but also shows the need for effective management of patients who can avoid reconsults, an overload of emergency services, increasedbed days and complications

Early ureteroscopic lithotripsy in acute renal colic caused by ureteral calculi.

PURPOSE: We aimed at comparing the success and complications of early semirigid ureteroscopy (URS) and elective URS in ureteral calculi with renal colic that do not respond to analgesics. METHODS: We retrospectively analyzed the data of 690 patients with obstructive ureteral stones who underwent URS with stone retrieval. 247 patients who underwent early URS within the first 12 h were classified as group I and 443 patients who underwent elective URS as group II. Both groups were compared in terms of age, sex, creatinine, eGFR, stone size, laterality, location and number of stones, type of lithotriptor, presence of hydronephrosis and success and complication rates. RESULTS: The mean age of the patients was 50.4 (18-89 years) (p > 0.05). There was no statistically significant difference between the groups in terms of age, eGFR, side, presence of hydronephrosis, fever, mucosal damage, stone migration, perforated ureter, ureteral avulsion, ureteral stent insertion at the end of the surgery and sepsis (p > 0.05). Both groups had male dominance (p > 0.05). Creatinine was significantly lower in Group I (p < 0.05). The mean stone size was also significantly lower in Group I (p < 0.05). Middle and proximal ureteral calculi were more common in Group II (p < 0.05). Multiple stones were higher in Group II (p < 0.05). The dominant type of lithotriptor used was pneumatic in Group I and laser in Group II (p < 0.05). Stone-free rates (SFRs) were higher in Group I (98% vs 90% in the first month) (p < 0.05). Postoperative hematuria and infection were more common in Group II (p < 0.05). CONCLUSIONS: In selected cases, early ureteroscopy is an effective and safe method for distal ureteral calculi smaller than 10 mm that are painful and resistant to analgesic treatment.

Acute Renal Colic Due to Immunoglobulin Free Light Chain Kidney Stones: A Case Report of an Unusual Complication of Multiple Myeloma.

Kidney failure is common in patients with a monoclonal gammopathy, most frequently due to hypercalcemia or myeloma cast nephropathy. Immunoglobulin crystallization is an uncommon phenomenon that also results in kidney injury. We report the case of a 74-year-old man with recurrent renal colic and acute kidney injury. He presented with κ light chain Bence-Jones proteinuria, hypogammaglobulinemia, anemia, and high plasma κ light chain level, leading to the diagnosis of κ light chain multiple myeloma. One calculus was collected and its analysis revealed a unique protein structure consisting of κ immunoglobulin free light chain. Genetic sequencing of the κ light chain identified a subgroup of variable domain previously identified as prone to crystallization. Eight cycles of cyclophosphamide-bortezomib-dexamethasone chemotherapy resulted in a partial hematologic response and kidney recovery without recurrence of renal colic. This rare case of urinary light chain nephrolithiasis highlights the importance of genetic and molecular analysis of the immunoglobulin variable domain to better understand the wide spectrum of monoclonal gammopathies.

Rare hereditary cause of chronic pancreatitis in a young male: SPINK1 mutation.

Hereditary chronic pancreatitis associated with a mutation in the serine protease inhibitor, Kazal Type-1 (SPINK-1 gene) is extremely rare. The SPINK1 mutation results in trypsinogen activation which predisposes to chronic pancreatitis predominately when combined with CFTR gene mutations. It presents as either chronic or recurrent acute pancreatitis. Symptom control and management of complications is important. Active surveillance with cross-sectional imaging for pancreatic malignancy in individuals with hereditary pancreatitis is advocated due to individuals being high risk. We present an unusual case of a young male who initially presented with renal colic and was incidentally diagnosed with severe chronic pancreatitis on abdominal imaging, with genetic testing confirming a homozygous SPINK1 mutation.

Mimicker of Renal Colic: Mesenteric Panniculitis.

A Mesenteric panniculitis is an uncommon disorder with unknown etiology. It may cause nonspesific abdominal or systemic symptoms. Radiological modalitis especially computed tomography are very helpful to make a diagnosis. Hence, the radiologist should be familiar with its tomographic findings to avoid further examinations and unnecessary surgery. We report computed tomography findings of mesenteric panniculitis in an adult patient with renal colic.

Care of acute renal colic: a survey of emergency medicine physicians.

INTRODUCTION: To determine the contemporary practice patterns of academic emergency department (ED) providers in the United States for an episode of acute renal colic. MATERIALS AND METHODS: A 30-question survey was developed to assess ED providers' clinical decision making for an index patient with acute renal colic. The survey population was all attending and resident physicians affiliated with an American emergency medicine residency program with an institutional profile available on the Society for Academic Emergency Medicine (156 programs; 95% of programs in the United States). The survey was conducted in October 2014. A response rate of 8.1% (289/3563) was achieved, which represented 29% (46/156) of the programs. RESULTS: Only 17% (53/289) of respondents were aware of the American Urological Association (AUA) guidelines on the management and imaging of ureteral calculi. A clinical care pathway was uncommon amongst institutions (6/46; 13%), but desired by providers (193/289; 67%). A low dose non-contrast computed tomography (CT) would be the most preferred initial diagnostic imaging modality (139/289; 48%). Initial imaging choice was not influenced by respondent role, program, census region, practice environment, ED size, ED volume, presence of a clinical care pathway, or knowledge of the AUA guidelines (all p > 0.05). CONCLUSIONS: In this cross-sectional survey of academic emergency medicine providers, we demonstrated a lack of awareness of quality initiatives and uncommon use of clinical care pathways. We observed that diagnostic imaging modalities with reduced radiation were commonly preferred, and that imaging preference was not associated with several demographic or institutional characteristics.

Spot urinary 5-hydroxyindoleacetic acid is not an ideal diagnostic test for acute appendicitis.

BACKGROUND AND PURPOSE OF THE STUDY: There is growing evidence to suggest the use of urinary 5-hydroxyindoleacetic acid (5-HIAA) test to help with the diagnosis of appendicitis. The aim of our study was to establish whether urinary 5-HIAA could be used as an effective diagnostic test for acute appendicitis. DESIGN AND METHODS: A prospective double-blinded study was carried out from December 2014 to October 2015. Patients admitted to the emergency surgical ward of a teaching hospital with suspected appendicitis were included in the study. The diagnostic accuracy of the test was measured by receiver operating characteristic curve. RESULTS: Ninety-seven patients were divided into 2 groups: acute appendicitis (n=38) and other diagnosis (n=59). The median value of urinary 5-HIAA was 24.19µmol/L (range, 5.39-138.27) for acute appendicitis vs 18.87µmol/L (range, 2.27-120.59) for other diagnosis group (P=.038). The sensitivity and specificity of urinary 5-HIAA at a cutoff value of 19µmol/L were 71% and 50%, respectively. Receiver operating characteristic analysis showed that the area under curve was 0.64 (confidence interval [CI], 0.513-0.737) for urinary 5-HIAA, which was lower than white blood cell count (0.69; CI, 0.574-0.797), neutrophil count (0.68; CI, 0.565-0.792), and C-reactive protein (0.76; CI, 0.657-0.857). There was no significant difference in the median values of 5-HIAA between different grades of severity of appendicitis (P=.704). CONCLUSION: Urinary 5-HIAA is not an ideal test for the diagnosis of acute appendicitis.

Laboratory markers has many valuable parameters in the discrimination between acute appendicitis and renal colic.

BACKGROUND: Only one diagnostic parameter is not available for acute appendicitis. For the establishment of diagnosis, combination of medical history, clinical, laboratory tests, and radiological imaging modalities are used so as to decrease the rates of negative laparotomy and morbidity secondary to delay in diagnosis. Thepresent study aimed to determine haematological and inflammatory markers which will be used in the discrimination of acute appendicitis (AA) and renal colic which are the most frequent and indistinguishable causes of abdominal pain in patients applying to the emergency service. METHODS: A total of 215 patients who presented with abdominal pain and who were histopathologically diagnosed as AA, and 200 patients who presented with abdominal pain and who were diagnosed as renal colic were included into the study. Control group consisted of 61 patients without any complaints who came to the outpatient clinics of internal medicine only for blood counts. Analyzed blood samples were WBC, RDW, Hb, MCV, MPV, neutrophil, lymphocyte, NLR and PLR. All differences associated with a chance probability of.05 or less were considered statistically significant. RESULTS: A statistically significant intergroup difference was seen between AA and renal colic groups as for age, WBC, Hb, MCV, neutrophil, lymphocyte, NLR and PLR. A statistically significant intergroup difference was seen between AA and control groups regarding age, WBC, Hb, RDW, MPV, neutrophil, lymphocyte, NLR and PLR. A statistically significant intergroup difference was seen between renal colic and control groups as for age, WBC, RDW, MPV, neutrophil and NLR. In ROC curve analysis, the area under AUCs for WBC, neutrophil, NLR and PLR were 0.896, 0.916, 0.888 and 0.725, respectively (p≤0.05). CONCLUSION: In the discrimination between patients with renal colic and those without any illness, WBC, RDW, MPV, neutrophil and NLR; in the differentiation between the patients with AA and healthy individuals, WBC, RDW, MPV, neutrophil, lymphocyte, NLR and PLR; and more importantly in the discrimination between patients with AA and those with renal colic who presented to emergency services with abdominal pain WBC, neutrophil, lymphocyte, PLR and NLR can be useful parameters.

Delayed-onset Ureteral Obstruction and Calcification Masquerading as Renal Colic Following Deflux Injection.

Vesicoureteral reflux is a common disorder in children, and its management has changed entirely as a result of widespread use of endoscopy procedures to inject filler materials. Complications with this type of treatment, particularly ureteral obstruction, are rare. Very few patients with delayed obstruction have been reported in the literature. We here present the case of an 8-year-old girl who exhibited symptoms of febrile renal colic and renal distension more than 5 years after undergoing endoscopic treatment. This is the first reported case of atypical late presentation combining pyelonephritis with ureteral obstruction and calcification.
