N?ive CD4+T cells play a key role in the initiation and maintenance of immune response.In the effect of cytokines and costimulatory molecules,they differentiate into Th1,Th2,Treg and Th17.Increasing evidences indicated that Th17 and Treg cells produce a significant effect on immune stability,autoimmune disease and cancer.Chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS)is the most common type of prostatitis,accounting for 90%~95%,which is closely correlated with the progression of be-nign prostatic hyperplasia and prostate cancer.Benign and malignant diseases of the prostate share much similarity in immune microen-vironment.Thus,this review summarizs the latest research progress on the mechanism of Th17/Treg cells in prostatic disease.

Laparoscopic renal pedicle lymphatic disconnection is the most effective method for treating chyluria that has failed to respond to conservative management. Chylous hemothorax is a rare clinical occurrence resulting from the anatomic abnormality. This paper reported a case, who was admitted with painless gross hematuria for 1 month and was diagnosed with left chylous hematuria. Laparoscopic left renal pedicle lymphatic disconnection was performed, and bilateral chylous hemothorax occurred after the operation. After conservative treatment such as bilateral closed thoracic drainage and blood transfusion support, the patient recovered well. After 2 months of follow-up, there was no obvious effusion in the bilateral thoracic cavity, and the chylous test of urine fluid was negative.

Objective :
To evaluate the application of routine ultrasound combined with contrast-enhanced ultra- sound( CEUS) for the renal wound after robotic-assisted nephron-sparing surgery(RANSS) and analyze the correla- tion with the postoperative complications.
Methods :
80 patients underwent RANSS were involved. Routine ultra- sound was performed to evaluate the morphological features the first day after the surgery.A classification system named the grades of ultrasound images ( GUIs) was build to evaluate the severity of the renal wound.CEUS was performed on postoperative day 1 to confirm the contrast agent extravasation from the renal wound.The incidence of postoperative complications in different grades was compared,meanwhile compared in the two groups of extravasa- tion or not.
Results :
In GUIs,the routine ultrasound images were classified to three grades : Grade1,Grade2, Grade3.The incidence of postoperative complications increased with GUIs(P<0. 05) ,meanwhile higher in the ex- travasation group(P<0. 05) .This trend matched up with GUIs especially in Grade 2 and 3.The incidence of the cases with extravasation increased with GUIs(P<0. 05) .
Conclusion
Routine ultrasound and CEUS are feasible to evaluate the morphologic changes of renal wound after RANSS.There is a certain correlation between the evalua- tion results and the postoperative complications.

OBJECTIVES:
To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery.
METHODS:
From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed.
RESULTS:
All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred.
CONCLUSIONS
The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.

8.Theoretical progress and practical application of prostate-pelvic syndrome
Acta Universitatis Medicinalis Anhui 2023;58(4):523-527
Abstract
Chronic prostatitis is one of the common diseases in male urology.The disease of type Ⅲ prostatitis (chronic prostatitis / chronic pelvic pain syndrome) in the classification of prostatitis in the National Institutes of Health (NIH) cannot reflect the nature of the disease,such as unclear etiology and pathogenesis,diverse clinical manifestations,insufficient diagnostic basis,etc.The concept of type Ⅲ prostatitis does not regard the pelvic floor and lower urinary tract as a functional whole.Therefore,the China Chronic Prostatitis Diagnostic Criteria and Effi- cacy Evaluation Collaborative Group proposed to change the name of type Ⅲ prostatitis to prostatic pelvic syndrome and explore the establishment of symptom-based diagnostic and efficacy evaluation criteria to reflect the nature of the disease and meet the treatment objectives of type Ⅲ prostatitis patients to improve symptoms and improve quality of life.The proposal of new theories and the development of multi-center clinical trials will help urologists deepen their understanding of the prostatic pelvic syndrome and help them to correctly diagnose and treat the syndrome.

Objective:To analyzed the urinary microbiota characteristics of upper tract urothelial carcinoma(UTUC) patients.Methods:Urine samples were collected from 23 patients with UTUC (UTUC group) and 22 patients with benign diseases (control group) admitted to Yijishan Hospital, the First Affiliated Hospital of Wannan Medical College from July 2021 to July 2022. The differences in age [(60.9±5.7) years vs. (61.4±8.8) years], sex (male/female: 15/8 vs. 9/13), and body mass index [(22.9±1.8) kg/m 2 vs. (23.4±1.7) kg/m 2] between the UTUC group and the control group were not statistically significant ( P>0.05). The V4 region of the 16S rRNA of urinary microorganisms was sequenced using the Illumina NovaSeq6000, and the results were processed using QLLME2. Differences in α-diversity between groups were analyzed by using the Shannon, Simpson, and Chao1 indices. Differences in β-diversity between groups were analyzed by using unweighted principal coordinates analysis (PCoA). Linear discriminant analysis Effect Size(LEfSe)was used to identify the bacterial taxa with different abundances between groups. Significant differences were defined as LDA>2. Results:The Chao1 index (703.12±265.54 vs. 506.20±214.02) and Shannon index (5.61±1.85 vs. 5.07±1.34) were significantly higher in the UTUC group compared to that in the control group ( P<0.05). The α-diversity of urinary microbes was elevated in the UTUC group compared to that in the control group but the difference in β-diversity was not statistically significant ( P=0.161). The enrichment of Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae abundance was higher in the urine of UTUC patients(LDA > 2). Further subgrouping analyses of the UTUC patients showed that the differences in Chao1 index (706.44±271.84 vs. 784.09±272.72), Shannon index (6.04±1.30 vs. 5.91±1.67), and Simpson index (0.94±0.08 vs. 0.89±0.22) between the muscle-invasive group and the non-muscle-invasive group were not statistically significant ( P>0.05). The difference in α-diversity between muscle-invasive and non-muscle-invasive group was not statistically significant, but the difference in β-diversity was statistically significant ( P=0.047). The urinary microbial communities of Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were enriched in muscle-invasive group and differed from that in non-muscle-invasive group(LDA>2). Conclusions:This study suggests that the urinary microbial community was more abundant in UTUC patients than in non-UTUC patients and that Bacteroidaceae, Ruminococcaceae, Acidaminococcaceae, Thermaceae, Erysipelatoclostridiaceae, and Coriobacteriaceae were more abundant in the urine of UTUC patients. The urinary microbial community was more abundant in the urine of non-muscle-invasive patients than in the muscle-invasive patients, and Gammaproteobacteria, Cutibacterium, Rhodococcus and Nocardiaceae were more abundant in the urine of non-muscle-invasive patients.
