The patients were randomly divided into two groups. Among them, 78 patients were selected to use the 7.5 Fr f-URS, which was designated as the GroupA. The remaining 127 patients were selected to use the 9.2 Fr f-URS, which served as the GroupB.

However, GroupA demonstrated superior performance compared to GroupB in operation duration (48 (40.55) min vs 74 (56.94) min), lithotripsy duration (35 (27.43) min vs 59 (42.78) min), and immediate postoperative SFR (53.52% (38/71) vs 29.41% (35/119)), with statistically significant differences observed (P < 0.05). In terms of complication occurrence, GroupA reported 10 cases of minor (Grade 1) complications, whereas GroupB had 32 cases of minor (Grade 1) complications and 7 cases of severe complications (including 2 cases of Grade 3 and 5 cases of Grade 4). The difference between the two groups was statistically significant (P < 0.05). The GroupA reported significantly fewer cases of postoperative fever (4) and analgesic treatment (3) compared to GroupB, which had 18 fever cases and 19 analgesic cases (P < 0.05).The GroupA did not experience any cases of septicemia or steinstrasse. Conversely, the GroupB had 5 cases of septicemia and 3 cases of steinstrasse, including 2 patients who underwent reoperation. Both groups also reported cases of ureteral mucosal rupture (5 in GroupA, 10 in GroupB), but these differences were not statistically significant (P > 0.05).</p><p><strong>Conclusion: </strong>Compared with 9.2 Fr f-URS combined with T-UAS, the use of 7.5 Fr f-URS with TFS-UAS in the treatment of kidney stones has higher lithotripsy efficiency and lower complication rate.

Furthermore, the majority of kidney-induced illnesses are frequently not readily identifiable in their early stages. Once they have progressed to a more advanced stage, they impact the individual's quality of life and burden the family and broader society. In recent years, to solve this challenge well, the application of machine learning techniques in renal medicine has received much attention from researchers, and many results have been achieved in disease diagnosis and prediction. Nevertheless, studies that have conducted a comprehensive bibliometric analysis of the field have yet to be identified.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;This study employs bibliometric and visualization analyses to assess the progress of the application of machine learning in the renal field and to explore research trends and hotspots in the field.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A search was conducted using the Web of Science Core Collection database, which yielded articles and review articles published from the database's inception to May 12, 2024.
