Abstract
BACKGROUND The last decades revealed new scientific knowledge regarding the fertility and potential malignancy of undescended testis AQ2(UDT). Accordingly, many guidelines changed their recommendation concerning timing of therapy, with the goal of an earlier time of surgery. METHODS We analyzed the number of new diagnosis and performed surgeries in predefined age groups provided by the obligatory annual reports of German hospitals in the reimbursement.INFO"-tool between 2006 and 2020. RESULTS Overall, 124,741 cases were analyzed. We showed a slight increase in performed surgeries in the first year by 2% per year with a main increase till 2011, a constant number of surgeries between first and 4th year and a decrease of surgeries between 5 and 14th year of living with a main decrease till 2009 by 3% per year. CONCLUSION Even if our results illustrate an increasing adaption of the guideline's recommendation, there is still a significant number of patients who receive later treatment. More research about the reasons and circumstances for the latter is needed.

Abstract
Background This study performed a systematic review and meta-analysis to compare the outcomes of the staged laparoscopic Fowler-Stephens Laparoscopic Orchiopexy (FSLO) and Staged Laparoscopic Traction Orchiopexy (SLTO) in patients with intra-abdominal testes (IAT). Methods This study reviewed literature published from 2016 to 2024. A systematic literature search was conducted on three databases: PubMed, ScienceDirect, and Google Scholar, using keywords (High intra abdominal testis) AND (("Fowler Stephens laparoscopic orchiopexy" OR (FSLO)) OR (Staged Laparoscopic traction orchiopexy OR (SLTO)). Non-randomized trials and observational studies comparing staged laparoscopic FSLO and SLTO, without any time range restriction are included. Studies without FLSO orchidopexy as a control, case reports, case studies, duplicate publication, no full text and non-English studies are excluded. This study used the PRISMA protocol, the Jadad Scale, and the Newcastle Ottawa Scale (NOS) to evaluate the included studies. To analyze statistical data, the Review Manager (RevMan) software was used. The Chi-squared test was used to calculate statistical heterogeneity in the meta-analysis. Results There were 240 patients from 5 studies (109 in the SLTO group and 131 FSLO in group). The primary outcome of this study is testicular descent and atrophy. There were no significant differences in testicular descent (RR:1.08[0.96 - 1.23],p<0.20,I 2:0%) and atrophy rate (RR:0.45[0.19 - 1.09],p<0.08,I 2:0%). Secondary outcomes are the duration of operation in both the first and second stages. Statistical analysis reveals a significantly lower first-stage operation time in the FSLO group (MD:9.31[7.08,11.55], p<0.05;I 2:94%). At the same time, lower second-stage operation times are significantly reported in the SLTO group (MD:-4.05[-7.99,-0.12],p<0.05; I 2:60%). Conclusions In terms of testicular descent and testicular atrophy the SLTO technique yields similar results to the FSLO technique. Both techniques have advantages and disadvantages, and we recommend SLTO as the first choice in children with a high IAT of <4 cm. PROSPERO registration CRD42023412407.

J Pediatr Urol 2023; 19:598-604. [PMID: 37328321 DOI: 10.1016/j.jpurol.2023.05.018] [Citation(s) in RCA: 17] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/14/2023] [Accepted: 05/27/2023] [Indexed: 06/18/2023]
Abstract
INTRODUCTION There is currently no clear consensus on the standards for using large language models such as ChatGPT in academic medicine. Hence, we performed a scoping review of available literature to understand the current state of LLM use in medicine and to provide a guideline for future utilization in academia. MATERIALS AND METHODS A scoping review of the literature was performed through a Medline search on February 16, 2023 using a combination of keywords including artificial intelligence, machine learning, natural language processing, generative pre-trained transformer, ChatGPT, and large language model. There were no restrictions to language or date of publication. Records not pertaining to LLMs were excluded. Records pertaining to LLM ChatBots and ChatGPT were identified and evaluated separately. Among the records pertaining to LLM ChatBots and ChatGPT, those that suggest recommendations for ChatGPT use in academia were utilized to create guideline statements for ChatGPT and LLM use in academic medicine. RESULTS A total of 87 records were identified. 30 records were not pertaining to large language models and were excluded. 54 records underwent a full-text review for evaluation. There were 33 records related to LLM ChatBots or ChatGPT. DISCUSSION From assessing these texts, five guideline statements for LLM use was developed: (1) ChatGPT/LLM cannot be cited as an author in scientific manuscripts; (2) If use of ChatGPT/LLM are considered for use in academic work, author(s) should have at least a basic understanding of what ChatGPT/LLM is; (3) Do not use ChatGPT/LLM to produce entirety of text in manuscripts; humans must be held accountable for use of ChatGPT/LLM and contents created by ChatGPT/LLM should be meticulously verified by humans; (4) ChatGPT/LLMs may be used for editing and refining of text; (5) Any use of ChatGPT/LLM should be transparent and should be clearly outlined in scientific manuscripts and acknowledged. CONCLUSION Future authors should remain mindful of the potential impact their academic work may have on healthcare and continue to uphold the highest ethical standards and integrity when utilizing ChatGPT/LLM.

Management of the undescended testis in children: An American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee Systematic Review. J Pediatr Surg 2022; 57:1293-1308.

Abstract
PURPOSE Management of undescended testes (UDT) has evolved over the last decade. While urologic societies in the United States and Europe have established some guidelines for care, management by North American pediatric surgeons remains variable. The aim of this systematic review is to evaluate the published evidence regarding the treatment of (UDT) in children. METHODS A comprehensive search strategy and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Five principal questions were asked regarding imaging standards, medical treatment, surgical technique, timing of operation, and outcomes. A literature search was performed from 2005 to 2020. RESULTS A total of 825 articles were identified in the initial search, and 260 were included in the final review. CONCLUSIONS Pre-operative imaging and hormonal therapy are generally not recommended except in specific circumstances. Testicular growth and potential for fertility improves when orchiopexy is performed before one year of age. For a palpable testis, a single incision approach is preferred over a two-incision orchiopexy. Laparoscopic orchiopexy is associated with a slightly lower testicular atrophy rate but a higher rate of long-term testicular retraction. One and two-stage Fowler-Stephens orchiopexy have similar rates of testicular atrophy and retraction. There is a higher relative risk of testicular cancer in UDT which may be lessened by pre-pubertal orchiopexy.

Unnecessary ultrasounds in children with undescended testes: An interrogation of the impact of the Choosing Wisely campaigns and clinical practice guidelines. Paediatr Child Health 2021; 26:299-304. [PMID: 34336058 PMCID: PMC8318542 DOI: 10.1093/pch/pxaa099] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Accepted: 07/30/2020] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES Over the past decade, clinical practice guidelines and educational campaigns have counselled against the use of routine ultrasound (US) in the diagnosis of undescended testes (UDT). We aimed to establish whether or not there has been change in the proportion of children with UDT undergoing pre-referral US prior to referral to our centre over this period. We also sought to determine whether type of referring specialist, UDT diagnosis, and patient distance from the hospital had impacted the rate of pre-referral US. METHODS A select sample of hospital charts of children undergoing orchidopexy at a single tertiary paediatric urological referral centre between 2010 and 2019 were reviewed. Data regarding age at surgery, cryptorchidism diagnosis, type of referring physician, patient distance from institution, and evidence of US as part of diagnostic work-up were extracted. RESULTS Five hundred charts were examined. Referring provider specialty impacted the number of US ordered (P=0.01). On subset analysis, paediatricians ordered fewer US for children with palpable UDT in 2014 (P=0.03). In 2018, community urologists ordered no US (P=0.02). These findings had temporal relationships with guideline release. The proportion of children undergoing US each year remained consistently between 50% and 62%, except in 2014, when only 36% had US. Distance from hospital and UDT diagnosis were of no significance. CONCLUSION Despite clinical practice guidelines and Choosing Wisely campaign recommendations, significant numbers of children with UDT still undergo US. Transient changes in sub-specialty guideline adherence are observed. Strategies to improve sustained guideline awareness in referring clinicians need to be considered.

Abstract
BACKGROUND Ultrasonography is the gold standard imaging method for scrotal investigation. Colour Doppler ultrasonography, contrast-enhanced ultrasonography and sonoelastography allow sonographers to assess size, echotexture, vascular features and stiffness of the scrotal organs and abnormalities. Scrotal ultrasonography has been used to investigate male reproductive health, scrotal pain, masses and trauma. However, ultrasonography thresholds/classifications used to distinguish normal and pathologic features of the scrotal organs have changed over time, and have not yet been fully standardized. OBJECTIVES To evaluate historical trends for the standards in scrotal ultrasonography: what was, what is and what will be normal. METHODS An extensive Medline search was performed identifying the most relevant studies in the English language from inception to date. RESULTS We provide here (i) a brief overview of the history of ultrasonography, (ii) current indications for scrotal ultrasonography and (iii) previous and current normal values, cut-offs and classifications of the main colour-Doppler ultrasonography parameters/characteristics of the scrotal organs, as derived from recent guidelines and evidence-based studies. In addition, we report recommendations and the clinical utility of contrast-enhanced ultrasonography and sonoelastography. Finally, we discuss critical issues needing further evidence and future directions to fill in the current gaps. DISCUSSION Several studies on scrotal ultrasonography are available. However, guidelines/recommendations dealing with specific ultrasonography applications have been published only in recent years. More recently, the European Academy of Andrology published evidence-based scrotal colour-Doppler ultrasonography reference ranges/normative parameters derived from a cohort of healthy, fertile men. In addition, a standardization of the methodology to evaluate qualitative and quantitative colour-Doppler ultrasonography parameters was reported. Other international societies reported indications, methodological standards, clinical utility and limitations of contrast-enhanced ultrasonography and sonoelastography. CONCLUSIONS To date, colour-Doppler ultrasonography normative values for the scrotal organs are available. However, a wide international consensus on assessment and classification of several ultrasonography parameters is still lacking. An alignment of the world societies on these issues is advocated.

Abstract
BACKGROUND There is a lack of a comprehensive evaluation for pediatric clinical practice guidelines (CPGs) published in recent years. Here, we assessed the quality of pediatric CPGs, considering factors that might affect their quality. The aim of the study is to promote a more coherent development and application of CPGs. METHODS Pediatric CPGs published in PubMed, MedLive, Guidelines International Network, National Institute for Health and Care Excellence, and World Health Organization between 2017 and 2019 were searched and collected. Paired researchers conducted screening, data extraction, and quality assessment using the Appraisal of Guidelines for Research and Evaluation II (AGREE II). Linear regression analysis determined the factors affecting CPGs' quality. RESULTS The study included a total of 216 CPGs, which achieved a mean score of 4.26 out of 7 points (60.86%) in the AGREE II assessment. Only 6.48% of the CPGs reached the "recommend" level. The remaining 69.91% should have been modified before recommendation, while the other 23.61% did not reach the recommended level at all. The overall quality of recent pediatric CPGs was higher than previously, and the proportion of CPGs with low-quality decreased over time. However, there were still too few CPGs that reached a high-quality level. The "applicability" and "rigor of development" domains had generally low scores. CPGs formulated by developing countries or regions, those that are not under an organizations or groups responsibility, and those that used non-evidence-based methods were found to be associated with poorer quality in different domains as independent or combinational factors. CONCLUSIONS The quality of pediatric CPGs still needs to be improved. Specifically, a quality control before applying new CPGs should be essential to ensure their quality and applicability.

Abstract
OBJECTIVES To systematically evaluate the effect of adjunctive hormonal therapy on testicular descent and spermatogenic function among children with cryptorchidism. METHODS A comprehensive literature search of electronic databases up to February 21, 2019 was performed. Continuous data of fertility indices were evaluated using weighted mean difference (WMD) with 95% confidence interval (CI), while nominal data of fertility indices and the complete descent rates were analyzed by risk ratio (RR) with 95% CI. A fixed effect or random effect model was used. RESULTS A total of 27 previous studies were included for the current analysis. Hormonal therapy increased complete testicular descent rate, reaching statistical significance (RR = 3.74; 95% CI, 2.78-5.04; P < 0.001). The success rate was 22.43%. A similar result was found in subgroup analysis of hormonal category and effect on unilateral or bilateral cryptorchidism. Studies reporting primary outcome as continuous data showed that cryptorchid males have significantly increased germ cell numbers per tubule (WMD = 0.10; 95% CI, 0.01-0.20, P = 0.032) after hormonal therapy. The nominal data of pooled studies showed no significant difference (RR = 1.62; 95% CI, 0.65-4.00, P = 0.298). In addition, a significant result was noted in the luteinizing hormone-releasing hormone (LHRH) therapy group but not in those undergoing human chorionic gonadotropin (hCG) treatment. CONCLUSIONS Our findings have demonstrated that hormonal therapy can effectively increase the success rate of complete testicular descent, while some boys may benefit as regards improvement of the fertility index.

Abstract
Background: To evaluate the efficacy and safety of 2nd-stage laparoscopic traction orchiopexy (Shehata technique) compared to Fowler-Stephens (F-S technique) for high intra-abdominal testes (IATs) in children. Patients and Methods: We performed a retrospective review of all children (<14 years old) who underwent laparoscopic treatment of high IAT in the pediatric surgery center of Yijishan Hospital of Wannan Medical College from April 2016 to April 2020. Participants were divided into the Fowler-Stephens (F-S) group and Shehata group according to the surgical method. We collected the medical records of all children and analyzed them statistically. Results: In this study, 43 patients in our center received 2nd-stage laparoscopic surgical treatment. The results showed that there were 23 high IATs in 22 patients in the F-S group and 22 IATs in 21 patients in the Shehata group. All patients completed the operation successfully. No significant difference in operation time was noted between the two groups. There was no significant difference in the testicular atrophy rate between the two groups (P = 0.323). The testicular retraction rate of the F-S group was greater than that of the Shehata group (P = 0.04). Conclusion:The results of this study indicate that the application of assisted laparoscopic testicular traction technology can effectively retain the main blood supply of the testis and vas deferens with a high survival rate and clear advantages. The preliminary results show that the Shehata technique is safe, reliable and effective in the treatment of high IAT in children.

Abstract
BACKGROUND Ultrasound (US) is the preferred imaging method for cryptorchidism, but most guidelines indicate that its value is questionable. The aim of this study was to evaluate the clinical value of ultrasonic mobility and testicular atrophy index (TAI) based on three‑dimensional US (3DUS) in preoperative and postoperative assessment of the undescended testis. MATERIAL AND METHODS Data from 158 children with unilateral extraperitoneal cryptorchidism were collected and their diagnoses were surgically confirmed. They were divided into different age groups and into 2 ultrasonic mobility groups: the mobile group (MG) and the restricted group (RG). Differences in sonographic characteristics between different groups were compared. Three-dimensional ultrasound performed with virtual organ computer-aided analysis (VOCAL) was used to determined preoperative and postoperative TAI and the reliability of TAI was analyzed. RESULTS Measurement of testicular volume with the VOCAL method was significantly more reliable than that done with the two-dimensional Lambert method. In all age groups, preoperative testicular volumes were smaller than that in the contralateral scrotal testis and postoperatively, they increased steadily. Both preoperative and postoperative TAI were higher in the RG than in the MG. In the MG, postoperative TAI decreased significantly in all age groups. In the RG, in contrast, effective volume growth was only achieved in patients who had undergone surgery before they reached age 1 year. CONCLUSIONS TAI values determined with 3DUS using the VOCAL technique objectively reflect recovery of testicular volume following surgery for undescended testicle. Ultrasonic mobility evaluation is beneficial for clinical management of the condition.

You J, Li G, Chen H, Wang J, Li S. Laparoscopic orchiopexy of palpable undescended testes_ experience of a single tertiary institution with over 773 cases. BMC Pediatr 2020; 20:124. [PMID: 32178653 PMCID: PMC7075009 DOI: 10.1186/s12887-020-2021-6] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Accepted: 03/04/2020] [Indexed: 11/24/2022] Open
Abstract
Background Discuss the superiority of laparoscopic orchiopexy in the treatment of inguinal palpable undescended testes. Methods Inclusion criteria: Preoperative examination and color Doppler ultrasound examination confirmed that the testes were located in the inguinal canal and could not be pulled into the scrotum, except for retractive and ectopic testes. The surgical steps were depicted as follow. The retroperitoneal wall was carved by ultrasonic scalpels, separates the spermatic vessels closed to the inferior pole of the kidney if necessary, dissects the peritoneum of vas deferens, cuts the testicular gubernaculum, and pulls back the testicle into the abdominal cavity. Besides, protect the vas deferens, and descend the testes to the scrotum and fix them without tension. Results There were 773 patients with 869 inguinal undescended palpable testes, 218 cases on the left side, 459 cases on the right side and 96 cases with bilateral undescended testes, whose age ranged from 6 months to 8 years, with an average of 20 months. All testes were successfully operated, no converted to open surgery. The average operation time was (34.8 ± 5.4) min. There were 692 testes have an ipsilateral patent processus vaginalis (89.5%); In 677 cases of unilateral cryptorchidism, 233 cases (34.4%) have a contralateral patent processus vaginalis, and laparoscopic percutaneous extraperitoneal closure the hernia sac carry out during the surgery. There was no subcutaneous emphysema during the operation, no vomiting, no abdominal distension, no wound bleeding and obvious pain after surgery, especially wound infection is rarely. Doppler ultrasound was evaluated regularly after surgery. The patients were followed up for 6 to 18 months. All the testes were located in the scrotum without testicular retraction and atrophy. No inguinal hernia or hydrocele was found in follow-up examination. Conclusion Laparoscopic orchiopexy manage inguinal palpable cryptorchidism is safe and effective, and there are obvious minimally invasive advantages. Furthermore, It could discover a contralateral patent processus vaginalis, and treat at the same time, which avoid the occurrence of metachronous inguinal hernia.

Kim JK, Chua M, Braga L, Langer JC, Hancock BJ, Lorenzo AJ, Bagli D, Farhat WA, Koyle MA. A Canadian national survey: understanding the differences in management of cryptorchidism among pediatric surgeons and pediatric urologists. J Pediatr Surg 2019; 54:1820-1824. [PMID: 30528200 DOI: 10.1016/j.jpedsurg.2018.10.053] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2018] [Revised: 09/08/2018] [Accepted: 10/04/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND This investigation aims to assess the variability in practice patterns regarding management of children with cryptorchidism (UDT) among pediatric urologists (U) and pediatric surgeons (S) practicing in Canada. METHODS All active members of Pediatric Urologists of Canada (PUC) and Canadian Association of Pediatric Surgery (CAPS) were invited to participate in an online multiple-choice type questionnaire with clinical scenarios in management of UDT. Responses were compared between U and S using Fisher's exact test. RESULTS The response rates were 74% and 79% among CAPS members (54/73) and PUC members (27/34) respectively. CAPS members were more likely to order diagnostic ultrasounds prior to surgery (44.4% vs 18.5%, p = 0.027). For palpable testis, most (80%) CAPS members favored the classic inguinal approach, while most PUC members did not demonstrate a clear preference, and were flexible with their approach depending on the position of the palpated testes (55%; p < 0.001). There was no statistically significant difference in preferred approach to unilateral or bilateral nonpalpable testis. However, for both palpable and nonpalpable bilateral UDT, more CAPS members preferred metachronous correction, compared to PUC members who opted to approach them synchronously (p = 0.008, 0.002, respectively). CONCLUSION Preferences with regard to use of diagnostic tools such as US, surgical approach for palpable testes and bilateral UDTs were not consistent between the two surgical specialties who perform orchidopexy across Canada. Both groups were compliant with guideline recommendations, with the exception of utilizing preoperative ultrasounds, which is uniformly not recommended by the most recent guidelines. LEVEL OF EVIDENCE This is a level II evidence study.

Abstract
OBJECTIVES Systematic reviews (SRs) of clinical practice guidelines (CPGs) are unique knowledge syntheses that require tailored approaches to, and greater subjectivity in, design and execution compared with other SRs in clinical epidemiology. We provide review authors structured direction on how to design and conduct methodologically rigorous SRs of CPGs. STUDY DESIGN AND SETTING A guidance paper outlining suggested methodology for conducting all stages of an SR of CPGs. We present concrete examples of approaches used by published reviews, including a case exemplar demonstrating how this methodology was applied to our own SR of CPGs. RESULTS Review context and the unique characteristics of CPGs as research syntheses or clinical guidance statements must be considered in all aspects of review design and conduct. Researchers should develop a "PICAR" statement to help form and focus on the research question(s) and eligibility criteria, assess CPG quality using a validated appraisal tool, and extract, analyze, and summarize data in a way that is cogent and transparent. CONCLUSION SRs of CPGs can be used to systematically identify, assess, and summarize the current state of guidance on a clinical topic. These types of reviews often require methodological tailoring to ensure that their objectives and timelines are effectively and efficiently addressed; however, they should all meet the criteria for an SR, follow a rigorous methodological approach, and adhere to transparent reporting practices.
