Use of ChatGPT in Urology and its Relevance in Clinical Practice: Is it useful?

PURPOUSE: One of the many artificial intelligence based tools that has gained popularity is the Chat-Generative Pre-Trained Transformer (ChatGPT). Due to its popularity, incorrect information provided by ChatGPT will have an impact on patient misinformation. Furthermore, it may cause misconduct as ChatGPT can mislead physicians on the decision-making pathway. Therefore, the aim of this study is to evaluate the accuracy and reproducibility of ChatGPT answers regarding urological diagnoses. MATERIALS AND METHODS: ChatGPT 3.5 version was used. The questions asked for the program involved Primary Megaureter (pMU), Enuresis and Vesicoureteral Reflux (VUR). There were three queries for each topic. The queries were inserted twice, and both responses were recorded to examine the reproducibility of ChatGPT's answers. Afterwards, both answers were combined. Finally, those rwere evaluated qualitatively by a board of three specialists. A descriptive analysis was performed. RESULTS AND CONCLUSION: ChatGPT simulated general knowledge on the researched topics. Regarding Enuresis, the provided definition was partially correct, as the generic response allowed for misinterpretation. For VUR, the response was considered appropriate. For pMU it was partially correct, lacking essential aspects of its definition such as the diameter of the dilatation of the ureter. Unnecessary exams were suggested, for Enuresis and pMU. Regarding the treatment of the conditions mentioned, it specified treatments for Enuresis that are ineffective, such as bladder training. Therefore, ChatGPT responses present a combination of accurate information, but also incomplete, ambiguous and, occasionally, misleading details.

Association between rectal diameter and response to treatment with parasacral transcutaneous electrical nerve stimulation and behavioral changes in children and adolescents with bladder and bowel dysfunction

ABSTRACT Purpose: Parasacral Transcutaneous Electrical Stimulation (TENS) is one of the treatments for children with Bladder and Bowel Dysfunction (BBD). Some studies showed that children with increased Rectal Diameter (RD) have more Functional Constipation (FC). However, RD prediction in maintenance of BBD after treatment was never evaluated. Our aim is to evaluate the association between RD and response to treatment in children and adolescents with BBD. Materials and Methods: This study evaluated patients from 5-17 years old with BBD. Dysfunctional Voiding Scoring System (DVSS), Rome IV criteria, and the Constipation Score were used. RD was measured using abdominal ultrasound before treatment according to the technique established by Klijn et al. and was considered enlarged when >3cm. No laxatives were used during treatment. Descriptive analysis and binary regression were performed and the area under the ROC curve was calculated. Results: Forty children were included (mean age 8.4±2.8 years, 52.5% male). Before treatment, RD was enlarged in 15 children (37.5%) (mean diameter 3.84±0.6cm), with FC persisting post-treatment in 11/15(73.3%). Those patients also required more laxatives following treatment and had more severe FC. Binary regression showed pretreatment RD to be an independent predictor of the persistence of FC post-treatment (OR=9.56; 95%CI:2.05-44.60). In ROC curve analysis, the sensitivity was 100% (95%CI: 0.49-1.0) and specificity 77.14% (95%CI:0.60-0.90) for rectal diameter >3 cm. The likelihood ratio was 4.38 (95%CI:2.40-8.0) for the persistence of BBD following treatment. Conclusion: RD appears to be relevant in the evaluation of children with BBD, not only as a diagnostic tool but also as a predictor of treatment outcome.

Agreement between the visual analogue scale (VAS) and the dysfunctional voiding scoring system (DVSS) in the post-treatment evaluation of electrical nerve stimulation in children and adolescents with overactive bladder.

INTRODUCTION: Electrical nerve stimulation is one of the most commonly used and well-tolerated treatments for overactive bladder (OAB); however, different studies have used different instruments to assess patients' response to treatment. OBJECTIVE: To analyze agreement between use of the visual analogue scale (VAS) and the Dysfunctional Voiding Scoring System (DVSS) for assessing improvement in urinary symptoms following electrical nerve stimulation treatment in children and adolescents with OAB. STUDY DESIGN: A cross-sectional analytical study including children and adolescents of 4-17 years of age diagnosed with OAB who underwent 20 sessions of transcutaneous (TENS) or percutaneous (PENS) electrical nerve stimulation. The DVSS and the VAS were used to assess daytime urinary symptoms before and following treatment. While the DVSS was always applied by a physician, the VAS was applied separately by a physiotherapist and then by a physician. Treatment was considered successful when the DVSS score was zero and the VAS score was ≥90%. Correlations between post-treatment VAS and DVSS scores were evaluated using the kappa coefficient. The VAS scores evaluated by the different professionals were compared for agreement using intraclass correlation and the Bland-Altman plot. RESULTS: Data from 49 cases were available for analysis. Of these, 27 (55.1%) were girls. Mean age was 7.1 ± 2.6 years. There was agreement between the two instruments used, the DVSS and the VAS, in 36/49 patients (73.5%), with a moderate Kappa of 0.44. There was moderate agreement between the VAS scores applied by the two different professionals. DISCUSSION: imitations of the present study include the small sample size and the fact that the inter-observer evaluation was conducted following a single sequence, i.e. all the patients were first evaluated by the physiotherapist and then by the physician, which may have biased answers and the post-treatment VAS scores. Furthermore, although the child participated actively in completing the questionnaires, in cases of divergent answers, the questions were redirected to the responsible adult, and the final answer may not fully represent the patient's true situation. CONCLUSION: The present study found moderate agreement between the DVSS and the VAS, and moderate agreement between VAS scores when the instrument was applied by two different professionals. Although both tools appear to be important, and possibly complementary, a DVSS score of zero precludes the need to apply the VAS.

Parasacral Transcutaneous Electrical Nerve Stimulation for the Treatment of Children and Adolescents with Bladder and Bowel Dysfunction: A Randomized Clinical Trial.

PURPOSE: Parasacral transcutaneous electrical nerve stimulation has been used to manage lower urinary tract symptoms refractory to standard urotherapy. Nevertheless, its actual effectiveness in treatment of bladder and bowel dysfunction remains to be established. We sought to evaluate the effectiveness of parasacral transcutaneous electrical nerve stimulation in the treatment of children with bladder and bowel dysfunction. MATERIALS AND METHODS: This was a randomized clinical trial conducted with children and adolescents of 5-17 years of age diagnosed with bladder and bowel dysfunction. Patients with neurological or anatomical abnormalities of urinary or digestive tracts, those unable to attend treatment sessions 3 times a week, individuals with diabetes mellitus or diabetes insipidus and those using anticholinergic drugs or laxatives were excluded from the study. The sample was divided into 2 groups: a control group submitted to standard urotherapy plus sham electrotherapy applied to the scapular region and a treatment group submitted to urotherapy plus parasacral transcutaneous electrical nerve stimulation. All the patients were submitted to 3, 20-minute electrotherapy (parasacral transcutaneous electrical nerve stimulation or sham) sessions/week for a total of 20 sessions. RESULTS: Forty patients were evaluated, 20 in the control group and 20 in the treatment group. Mean age (±standard deviation) was 8.4±2.8 years and 52.5% were male. In 15 patients (37.5%), rectal diameter was ≥3 cm. Lower urinary tract symptoms improved in both groups following treatment, with no statistically significant differences in Dysfunctional Voiding Scoring System score, lower urinary tract symptoms or uroflowmetry patterns between the groups. Intragroup evaluation showed a significant improvement in enuresis in the treatment group. There was a significant improvement in functional constipation post-intervention in treatment group compared to control group (70% vs 20%, p=0.004). CONCLUSIONS: Parasacral transcutaneous electrical nerve stimulation is effective for treatment of bladder and bowel dysfunction in children and adolescents, particularly insofar as functional constipation is concerned.
