OBJECTIVE
Gallstone disease (GSD) is one of the common digestive tract diseases with a high worldwide prevalence. The effects of GSD on patients include but are not limited to the symptoms of nausea, vomiting, and biliary colic directly caused by GSD. In addition, there is mounting evidence from cohort studies connecting GSD to other conditions, such as cardiovascular diseases, biliary tract cancer, and colorectal cancer. Early identification of patients at a high risk of GSD may help improve the prevention and control of the disease. A series of studies have attempted to establish prediction models for GSD, but these models could not be fully applied in the general population due to incomplete prediction factors, small sample sizes, and limitations in external validation. It is crucial to design a universally applicable GSD risk prediction model for the general population and to take individualized intervention measures to prevent the occurrence of GSD. This study aims to conduct a multicenter investigation involving more than 90000 people to construct and validate a complete and simplified GSD risk prediction model.
METHODS
A total of 123634 participants were included in the study between January 2015 and December 2020, of whom 43929 were from the First Affiliated Hospital of Chongqing Medical University (Chongqing, China), 11907 were from the First People's Hospital of Jining City (Shandong, China), 1538 were from the Tianjin Medical University Cancer Institute and Hospital (Tianjin, China), and 66260 were from the People's Hospital of Kaizhou District (Chongqing, China). After excluding patients with incomplete clinical medical data, 35976 patients from the First Affiliated Hospital of Chongqing Medical University were divided into a training data set (=28781, 80%) and a validation data set (=7195, 20%). Logistic regression analyses were performed to investigate the relevant risk factors of GSD, and a complete risk prediction model was constructed. Factors with high scores, mainly according to the nomograms of the complete model, were retained to simplify the model. In the validation data set, the diagnostic accuracy and clinical performance of these models were validated using the calibration curve, area under the curve (AUC) of the receiver operating characteristic curve, and decision curve analysis (DCA). Moreover, the diagnostic accuracy of these two models was validated in three other hospitals. Finally, we established an online website for using the prediction model (The complete model is accessible at https://wenqianyu.shinyapps.io/Completemodel/, while the simplified model is accessible at https://wenqianyu.shinyapps.io/Simplified/).
RESULTS
After excluding patients with incomplete clinical medical data, a total of 96426 participants were finally included in this study (35876 from the First Affiliated Hospital of the Chongqing Medical University, 9289 from the First People's Hospital of Jining City, 1522 from the Tianjin Medical University Cancer Institute, and 49639 from the People's Hospital of Kaizhou District). Female sex, advanced age, higher body mass index, fasting plasma glucose, uric acid, total bilirubin, gamma-glutamyl transpeptidase, and fatty liver disease were positively associated with risks for GSD. Furthermore, gallbladder polyps, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and aspartate aminotransferase were negatively correlated to risks for GSD. According to the nomograms of the complete model, a simplified model including sex, age, body mass index, gallbladder polyps, and fatty liver disease was constructed. All the calibration curves exhibited good consistency between the predicted and observed probabilities. In addition, DCA indicated that both the complete model and the simplified model showed better net benefits than treat-all and treat-none. Based on the calibration plots, DCA, and AUCs of the complete model (AUC in the internal validation data set=74.1% [95% CI: 72.9%-75.3%], AUC in Shandong=71.7% [95% CI: 70.6%-72.8%], AUC in Tianjin=75.3% [95% CI: 72.7%-77.9%], and AUC in Kaizhou=72.9% [95% CI: 72.5%-73.3%]) and the simplified model (AUC in the internal validation data set=73.7% [95% CI: 72.5%-75.0%], AUC in Shandong=71.5% [95% CI: 70.4%-72.5%], AUC in Tianjin=75.4% [95% CI: 72.9%-78.0%], and AUC in Kaizhou=72.4% [95% CI: 72.0%-72.8%]), we concluded that the complete and simplified risk prediction models for GSD exhibited excellent performance. Moreover, we detected no significant differences between the performance of the two models (>0.05). We also established two online websites based on the results of this study for GSD risk prediction.
CONCLUSIONS
This study innovatively used the data from 96426 patients from four hospitals to establish a GSD risk prediction model and to perform risk prediction analyses of internal and external validation data sets in four cohorts. A simplified model of GSD risk prediction, which included the variables of sex, age, body mass index, gallbladder polyps, and fatty liver disease, also exhibited good discrimination and clinical performance. Nonetheless, further studies are needed to explore the role of low-density lipoprotein cholesterol and aspartate aminotransferase in gallstone formation. Although the validation results of the complete model were better than those of the simplified model to a certain extent, the difference was not significant even in large samples. Compared with the complete model, the simplified model uses fewer variables and yields similar prediction and clinical impact. Hence, we recommend the application of the simplified model to improve the efficiency of screening high-risk groups in practice. The use of the simplified model is conducive to enhancing the self-awareness of prevention and control in the general population and early intervention for GSD.

This case report introduces a rare occurrence of transverse colon volvulus associated with persistent descending mesocolon (PDM), a congenital anomaly characterized by the medial positioning of the descending colon due to a failed fusion with the dorsal abdominal wall. We detail the case of an 18-year-old female, with a medical history of surgically corrected coarctation of the aorta and anal atresia, who presented with recurrent transverse colon volvulus despite having undergone a laparoscopic colopexy three years earlier. Physical examination revealed abdominal distension and metallic colic sounds while imaging studies confirmed the recurrence of the volvulus. Laparoscopic partial resection of the transverse colon was performed, which revealed a medially positioned descending colon due to PDM. Postoperative complications included anastomotic failure, necessitating a second operation. The patient was successfully discharged without further complications after seven days. This case underscores the clinical significance of recognizing PDM, highlighting its potential role in causing transverse colon volvulus and increasing the risk of anastomotic failure. It emphasizes the need for surgeons to remain vigilant regarding this congenital anomaly to mitigate unexpected outcomes such as recurrent volvulus and postoperative complications.

Pain after vaginal prolapse repair surgery with mesh is generally attributed to the mesh fixation, particularly to mesh erosion, dislocation or the development of hematoma. However, once all the causes have been excluded, the urinary system, bladder and ureters should be accurately examined by means of endovaginal ultrasound. This report concerns the case of a 72-year-old woman who had undergone mesh-supported prolapse surgery 3 months prior, with no other relevant diseases, who visited the emergency department complaining of dull, right-sided colic pain. The endovaginal ultrasound examination revealed a prevesical ureteral calculus on the right side with consequent dilatation of the proximal ureter. Computed tomography of the abdomen and pelvis confirmed the calculus in the distal right ureter and revealed a right renal lower pole calculus. The patient underwent treatment via an operative ureterorenoscopy with removal of stones and placement of a double-J-stent. Two months later, a second ureterorenoscopy was performed with double-J-stent removal and concomitant stone extraction. It appears that no similar cases have been reported in the literature. This is why, during the urogynecological postoperative follow-up, it is of paramount importance to examine the entire urogenital system with endovaginal ultrasound. This case report highlights how, through a simple, non-invasive, radiation-free examination, like ultrasound, most of the post-operative complications of vaginal prolapse repair surgery using mesh, including urolithiasis, can be excluded.

Urology Jun 2024To explore how Michel de Montaigne's battle with urolithiasis influenced his writings and philosophical outlook during the Renaissance period.
OBJECTIVE
To explore how Michel de Montaigne's battle with urolithiasis influenced his writings and philosophical outlook during the Renaissance period.
MATERIALS AND METHODS
The study examines historical texts, Montaigne's personal essays, and contemporary medical literature from the Renaissance era. A comprehensive review of Montaigne's extensive travels across Europe, interactions with prominent physicians, and the various treatments he sought for urolithiasis is conducted. The analysis focuses on how these experiences shaped his literary work and philosophical reflections.
RESULTS
Montaigne's struggle with urolithiasis began at the age of 45, profoundly impacting his life and writings. His journey through France, Germany, Switzerland, Austria, and Italy in search of relief, along with consultations with renowned physicians such as Félix Platter and Girolamo Borro, significantly influenced his philosophical inquiries into human suffering and mortality. Montaigne's detailed accounts of his condition, describing 19 episodes of renal colic, offered early patient-centered perspectives in medical literature, highlighting the importance of understanding the psychological and emotional dimensions of illness. His therapeutic use of thermal baths and other non-invasive treatments reflected the medical practices of the time.
CONCLUSION
Montaigne's experience with urolithiasis not only shaped his philosophical essays but also underscored the importance of empathetic and holistic patient care. His writings emphasize the need for integrating patient narratives into medical practice, a concept that remains crucial in contemporary healthcare. Montaigne's legacy continues to inspire a compassionate approach to urological care, emphasizing the interconnected nature of physical and emotional well-being, and advocating for a more patient-centered perspective in medical treatments.

BACKGROUND
Ureteric colic is a common emergency urological presentation [1]. When operative intervention is required, retrograde ureteroscopy is the most common approach. There are multiple treatment strategies including primary ureteroscopy (URS), staged ureteroscopy, and deferred ureteroscopy following ureteric stent placement. The approach is based on a number of clinical and stone factors. This study assesses the factors which predict stone clearance at the initial procedure.
AIMS
All patients diagnosed with an obstructing ureteric stone who were managed operatively in a consecutive 12-month period were included. Patients were evaluated for stone clearance following a single or multiple procedures. A number of factors including stone size, location, gender, age and pre-operative laboratory results were evaluated for association with stone clearance at index procedure. Multivariate logistic regression analyses were performed to produce odds ratios (OR) with confidence interval (CI) at 95% and significance values P < 0.05.
RESULTS
One hundred and seventy patients were included in the final analysis. Stone clearance following the index procedure was achieved in 57% (n = 100) of patients. Predictors of successful stone clearance at index procedure were stone size < 6 mm, male gender and distal stone location (p < 0.05). Proximal stone location, stone size > 10 mm and elevated c-reactive protein (CRP) were associated respectively with multiple procedures to achieve stone clearance (p < 0.05).
CONCLUSIONS
Acute ureteric stones can be managed with a number of treatment strategies. This study identifies factors which predict stone clearance at index procedure. These results will help urologists accurately counsel patients when undertaking operative management for ureteric colic.

Peritoneal dialysis (PD) catheter migration is a common complication of PD which usually results in obstruction of dialysate outflow. We report the first known case in the literature of a 62-year-old male with end-stage renal disease on PD who presented with acute renal colic secondary to the PD catheter overlying right mid-ureter causing hydronephrosis with spontaneous resolution of pain and hydronephrosis two days later. The patient was discharged home with a functioning dialysis catheter and complete resolution of both symptoms and radiographic findings of hydronephrosis. While management of migrated PD catheters usually require surgical intervention, our case resolved without intervention.

This paper introduces a novel one-dimensional convolutional neural network that utilizes clinical data to accurately detect choledocholithiasis, where gallstones obstruct the common bile duct. Swift and precise detection of this condition is critical to preventing severe complications, such as biliary colic, jaundice, and pancreatitis. This cutting-edge model was rigorously compared with other machine learning methods commonly used in similar problems, such as logistic regression, linear discriminant analysis, and a state-of-the-art random forest, using a dataset derived from endoscopic retrograde cholangiopancreatography scans performed at Olive View-University of California, Los Angeles Medical Center. The one-dimensional convolutional neural network model demonstrated exceptional performance, achieving 90.77% accuracy and 92.86% specificity, with an area under the curve of 0.9270. While the paper acknowledges potential areas for improvement, it emphasizes the effectiveness of the one-dimensional convolutional neural network architecture. The results suggest that this one-dimensional convolutional neural network approach could serve as a plausible alternative to endoscopic retrograde cholangiopancreatography, considering its disadvantages, such as the need for specialized equipment and skilled personnel and the risk of postoperative complications. The potential of the one-dimensional convolutional neural network model to significantly advance the clinical diagnosis of this gallstone-related condition is notable, offering a less invasive, potentially safer, and more accessible alternative.

BACKGROUND
The survival of horses diagnosed with critical colic (requiring referral or euthanasia) relies on rapid and effective decision-making by the owner and veterinary practitioner.
OBJECTIVES
To explore UK horse owners' and veterinary practitioners' experiences of decision-making for critical cases of equine colic.
STUDY DESIGN
Qualitative study using a phenomenological approach.
METHODS
Individual, semi-structured telephone interviews were conducted with 14 horse owners and 13 veterinary practitioners (vets) who had experienced a critical decision (referral or euthanasia) for a horse with colic. A purposive, convenience sample of participants was recruited. Sessions explored participant's experience of colic, including recognition, help-seeking behaviour, and challenges. Thematic analysis was performed on collected data.
RESULTS
Four over-arching themes were identified; 'head', 'heart', 'practicalities' and 'impact'. Owners acknowledged responsibility for their horse's welfare but had different perspectives than vets on the importance of finance ('head'). Both vets and owners described how the horse-human relationship ('heart') often led to conflict during decision-making. The vet-client relationship was influential on decision-making for both owners and vets; involving other people in decision-making was described both positively and negatively by participants ('heart'). 'Practicalities', such as lack of preparedness, transport issues and adverse weather conditions, were identified by both owners and vets as barriers. Owners described a 'rollercoaster' of emotions after a critical decision, with profound impacts on their mental wellbeing, feelings of guilt, and long-term changes in behaviour ('impact'), and a lack of support to manage these feelings.
MAIN LIMITATIONS
Small sample size.
CONCLUSIONS
This study describes stakeholder decision-making during critical cases of equine colic. Factors that commonly influenced decisions included an owner's previous knowledge and beliefs, social pressures, logistics and the relationship between the owner and vet. The study highlighted long-term impacts on the owner, including their management and decisions for subsequent horses. These factors should be considered in shared decision-making.

BACKGROUND AND AIM
Colic is the primary problem affecting equestrian care worldwide. The primary cause of colic is digestive diseases; however, they can also affect organs from different systems in the abdominal region. In addition to a prior history of the disease and its treatment, risk factors may be assessed to determine the etiology of the disease in horses without or with a history of colic. This study aimed to present a summary of the incidence, risk factors, and medical procedures for colic in horses.
MATERIALS AND METHODS
Based on owner reports, 223 horses in Tuban, Indonesia, suspected of having colic were investigated. During the investigation of clinical parameters, investigators went door-to-door with interested horse owners to gather information about potential risk factors related to equine colic. Information on horses diagnosed with colic was obtained from the medical records of treatment. A Chi-square test was used to investigate the potential association between the risk factors, medical protocol, and the outcome of colic in horses.
RESULTS
Of the 187 cases, spasmodic colic was the most common (48.13%), but 17 (9.09%) had no definitive diagnosis. Poor body condition scores (χ = 58.73; p < 0.001), wheat bran feeding (χ = 26.79; p < 0.001), concentrate (χ = 10.66; p < 0.01), less access to water (χ = 128.24; p < 0.001), recurrence of colic (χ = 85.64; p < 0.001), no deworming program (χ = 54.76; p < 0.001), the presence of gastrointestinal parasites (χ = 56.79; p < 0.001), stressed physical activity (χ = 28.53; p < 0.001), and summer season (χ = 7.83; p < 0.01) were the risk factors for colic. We further reported that 185 (98.93%) patients who received the following medical interventions recovered: injection of non-steroidal anti-inflammatory drugs was necessary, Vitamin B complex (χ = 39.98; p < 0.001), fluid therapy (χ = 92.99; p < 0.001), and gastric intubation (χ = 4.09; p < 0.05).
CONCLUSION
The importance of colic was demonstrated in 187 (83.86%) of the 223 horses investigated in Tuban, Indonesia, documented. In this study, recommendations for medical procedures when colic risk factors have been determined are presented.

A 41-year-old woman presented with acute, severe left-sided abdominal pain and vomiting at 37 weeks' gestation. Her symptoms were attributed to renal colic, and she was admitted for supportive treatment. During her admission, she went into spontaneous labour. Due to other obstetric indications, the team proceeded with delivery by emergency caesarean section. Intra-operatively, a necrotic left fallopian tube and ovary were identified, and a diagnosis of adnexal torsion (AT) was recognised. There was no return of tissue perfusion on de-torsion, and a left salpingo-oopherectomy was performed. AT in pregnancy is unusual, with only a minority of cases occurring in the third trimester. This is a challenging diagnosis to establish and requires a high index of suspicion. Ultrasound and magnetic resonance imaging can be helpful in establishing a diagnosis but should not delay definitive treatment. Prompt surgical intervention is paramount to prevent irreversible damage to ovarian tissue.
