The Clinical Research of Traditional Chinese Medicine Formula

1\. Study Design and Methods 1.1 Research Method A multicenter, open-label study design was used. 1.2 Source of Participants The cases in this clinical observation were recruited from the Department of Urology at the Fourth Affiliated Hospital of Zhejiang University School of Medicine, Yiwu Traditional Chinese Medicine Hospital, and Fujian Provincial People's Hospital. All patients were diagnosed with upper urinary tract stones (including kidney stones and ureteral stones) and underwent ureteroscopic holmium laser lithotripsy and stone removal. A 4.7F, 28 cm double-J stent was left in place postoperatively, and patients returned to the hospital 4 weeks later for stent removal. Participants were randomly assigned to either the "Four-Ingredient Formula for Nourishing the Kidneys and Promoting Blood Circulation" group or the control group using a random number table. Informed consent was obtained from all enrolled participants.

1.3 Participant Selection and Exclusion Criteria 1.3.1 Western Medicine Diagnostic Criteria According to the definitions of renal stones and ureteral stones in \*Practical Urology\*, a diagnosis of renal stones or ureteral stones is made based on the presence or absence of stone-related symptoms and signs, in conjunction with the patient's medical history and the results of a urinary tract color Doppler ultrasound and non-contrast abdominal CT scan performed after admission.

1.3.2 Traditional Chinese Medicine Diagnostic Criteria

Based on clinical manifestations, in accordance with the \*Guidelines for Clinical Research on New Traditional Chinese Medicines\* and the \*General Principles for Clinical Research on New Traditional Chinese Medicines\*-both formulated in accordance with the National Standards of the People's Republic of China-and with reference to the views of various scholars, the following criteria have been established:

Kidney Deficiency with Blood Stasis and Damp-Heat Syndrome Principal Symptoms: Distending, aching, stabbing, or localized pain in the lower back and abdomen, occurring intermittently and worsening with exertion; may be accompanied by hematuria, vomiting, or painful and difficult urination; or may be asymptomatic.

Secondary Symptoms: Dry mouth and throat or a dark red throat; rough skin or numbness in the limbs; a red or predominantly red tongue, or a dark purple tongue with ecchymoses or petechiae; and a fine, thin pulse.

At least one of the primary symptoms and at least two of the secondary symptoms must be present, and the tongue and pulse findings must be consistent.

1.3.3 Inclusion Criteria

1. Meets Western medical diagnostic criteria, requires surgical removal of stones, and has a 4.7F, 28 cm double-J stent placed postoperatively; plain radiographs of the kidneys and upper bladder indicate that the ureteral stent is properly positioned and no secondary surgery is required; 2. Meets the Traditional Chinese Medicine syndrome differentiation criteria; 3. Age 18 ≤ age ≤ 80; 4. Voluntarily participate and sign an informed consent form. 1.3.4 Exclusion Criteria

1. The investigator determines that it is necessary to stop the study from an ethical perspective; 2. Serious adverse events occur, and the participant should no longer continue the trial; 3. Serious co-morbidities arise during treatment; 4. The investigator determines that withdrawal from the study is in the participant's best interest; 5. Other reasons. 1.3.5.2 Participant-Determined Withdrawal Participants have the right to withdraw from the trial at any stage, or if the participant does not withdraw informed consent but fails to continue medication or follow-up, they are considered lost to follow-up.

1.3.6 Dropout Criteria

1. Serious adverse events or complications occur; 2. The participant requests to withdraw from the trial during the study; 3. Unable to contact the participant during the trial. 1.3.7 Exclusion Criteria

(1) Found to not meet inclusion criteria after enrollment; (2) Poor compliance with the study protocol, including not following prescribed medication or clinical tests; (3) Incomplete data during the trial, making it impossible to evaluate the drug's efficacy and safety.

Formulation: Decoction Dosage: 150 ml per dose Source: Zhejiang Sanxi Tang Chinese Medicine Co., Ltd. 2.4.2 Grouping This study involves two groups: In accordance with the principles of randomized controlled trials, patients were divided into a control group and an experimental group, each consisting of 40 patients. The control group received standard treatment (postoperative anti-infective therapy, fluid replacement, hemostasis, antispasmodic and analgesic therapy, and other symptomatic treatments), while the experimental group received, in addition to standard treatment, an oral decoction of the "Bushen Huoxue Simiao formula" (one dose per day, taken twice-once 30 minutes before breakfast and once 30 minutes after dinner).

Randomization Method: Random numbers (1-80) are generated using SPSS software and randomly assigned to the Bushen Huoxue Simiao formula group and the control group, each receiving 40 numbers. The distribution results are kept confidential by the group leader, who determines and records the grouping and sequence number of patients.

2.5 Statistical Analysis Method SPSS v22.0 will be used for statistical analysis. Categorical data will be analyzed using the χ² test. Continuous data will be presented as means ± standard deviations (SD) and compared using t-tests. Statistical significance is set at p \< 0.05.
