[Clinical value of fluorescence laparoscopy in pelvic lymph node dissection for intermediate- and high-risk prostate cancer patients].

OBJECTIVE: We explore the clinical value of fluorescence laparoscopy in the management of intermediate- and high-risk prostate cancer (PCa) patients by radical prostatectomy plus pelvic lymph node dissection (RP+PLND). METHODS: We retrospectively analyzed the clinical data on 45 PCa patients (32 intermediate- and 13 high-risk cases) treated by RP+PLND in our hospital from 2018 to 2020. The patients received injection of 1 ml Indocyanine Green bilaterally into the prostate under the cystoscope 30 minutes before surgical dissection of the lymph nodes, including those by the external iliac, distal internal iliac and obturator, common and presacral ones, and those visualized in the fluorescence image. We recorded the total numbers of lymph nodes, the fluorescence-manifested ones, and the positive ones. RESULTS: The mean postoperative Gleason score of the patients was 7.5 ± 0.7. Totally 967 lymph nodes were removed, and 134 were observed under the fluorescence laparoscope in 42 cases. Fourteen positive lymph nodes were found in 5 cases. Positive lymph nodes were also detected by the external iliac, distal internal iliac and obturator in 4 cases, with a sensitivity of 80% and a specificity of 100%. Fluorescence imaging exhibited positive lymph nodes in the lymphangion in 3 cases, with a sensitivity of 60% and a specificity of 100%. The lymph nodes by the external iliac, distal internal iliac and obturator and the fluorescence-manifested ones were also dissected, which were found positive in 5 cases, with a sensitivity of 100% and a specificity of 100%. CONCLUSION: Pelvic lymph nodes can be observed by fluorescence laparoscopy in most PCa patients. Dissection of the lymph nodes by the external iliac, distal internal iliac and obturator and the fluorescence-manifested ones contributes to a higher detection rate of positive pelvic lymph nodes in intermediate- and high-risk PCa patients.

[Entecavir improves the reproductive function of male patients with chronic hepatitis B].

OBJECTIVE: To study the effect of entecavir on the reproductive function of male patients with chronic hepatitis B (CHB). METHODS: This study included 56 CHB male patients (aged 18－45 ï¼»33.14 ± 5.38ï¼½ years) initially treated with entecavir at 0.5 mg/d for 24 weeks from 2015 to 2018 and another 24 healthy fertile male volunteers (aged 21－45 ï¼»32.62 ± 5.94ï¼½ years) as normal controls. We obtained the body mass index (BMI), reproductive hormone levels, semen parameters and IIEF-5 scores from the subjects and compared them between the two groups before and after treatment. RESULTS: There were no statistically significant differences between the CHB and normal control groups in age, BMI, lifestyle and baseline reproductive hormone levels except in the levels of FSH (ï¼»3.92 ± 1.29ï¼½ vs ï¼»3.08 ± 0.85ï¼½ mIU/ml, P = 0.003) and E2 (ï¼»35.79 ± 7.49ï¼½ vs ï¼»28.25 ± 7.09ï¼½ pg/ml, P < 0.01). The semen parameters were significantly lower in the CHB patients than in the normal controls, including total sperm motility (ï¼»37.75 ± 13.33ï¼½% vs ï¼»49.58 ± 9.27ï¼½%, P = 0.004), the percentage of progressively motile sperm (PMS) (ï¼»30.70 ± 10.03ï¼½% vs ï¼»42.46 ± 8.90ï¼½%, P < 0.01), sperm concentration (ï¼»51.51 ± 19.50ï¼½ vs 70.33 ± 30.62) ×106/ml, P = 0.007), and total sperm count (ï¼»160.2 ± 51.8ï¼½ vs ï¼»225.91 ± 97.97ï¼½ ×106, P = 0.002), and so were the IIEF-5 scores (19.32 ± 2.34 vs 21.25 ± 2.35, P = 0.0006). After 24 weeks of entecavir treatment, the CHB patients showed no significant difference from the baseline in the semen volume, semen pH and days of abstinence, but remarkable improvement in total motility (ï¼»37.75 ± 13.33ï¼½ vs ï¼»44.1 ± 11.89ï¼½%, P = 0.004), PMS (ï¼»30.70 ± 10.03ï¼½ vs ï¼»38.30 ± 7.42ï¼½%, P < 0.01), sperm concentration (ï¼»51.51 ± 19.50ï¼½ vs ï¼»62.00 ± 24.64ï¼½ ×106/ml, P = 0.007), total sperm count (ï¼»160.21 ± 51.8ï¼½ vs ï¼»207.65 ± 81.69ï¼½ ×106, P = 0.0002), and IIEF-5 score (20.13 ± 1.82 vs 19.32 ± 2.34, P = 0.02). CONCLUSIONS: CHB patients have lower sexual function and semen quality than normal males. Entecavir can significantly improve the liver function, sexual function and semen quality of the CHB patients, but whether it directly improves the sexual function and semen quality of the patients or indirectly through liver function improvement needs to be further studied.

[Transurethral resection of the prostate versus transurethral holmium laser enucleation of the prostate for benign prostatic hyperplasia with bladder detrusor overactivity].

OBJECTIVE: To compare and analyze the effects of transurethral resection of the prostate (TURP) and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) with bladder detrusor overactivity. METHODS: his study included 51 cases of BPH with bladder detrusor overactivity treated by TURP and another 58 treated by HoLEP. We evaluated the urination of the two groups of patients during the recovery period and at 3 and 6 months postoperatively. RESULTS: There were no statistically significant differences in such baseline data as the blood PSA level, prostate volume, International Prostate Symptom Score (IPSS), and quality of life (QOL) between the two groups of patients, except in effective bladder capacity, which was higher in the TURP than in the HoLEP group (ï¼»315±59ï¼½ vs ï¼»287±76ï¼½ ml, P<0.05). Urine storage symptoms were obviously improved in both of the groups postoperatively, with the storage symptoms score significantly decreased from 12.6±4.9 preoperatively to 7.5±3.9 at 3 months and 6.1±4.2 at 6 months after surgery in the TURP group (P<0.01) and from 13.7±5.7 to 7.9±4.2 and 7.0±5.1 in the HoLEP group (P<0.01). HoLEP manifested significant advantages over TURP in the postoperative urethral catheterization time (ï¼»2.7±0.8ï¼½ vs ï¼»5.1±1.2ï¼½ d, P<0.05), postoperative bladder contracture time (ï¼»4.1±1.9ï¼½ vs ï¼»5.8±2.4ï¼½ d, P<0.05), postoperative hospital stay (ï¼»4.4±1.8ï¼½ vs ï¼»5.9±2.5ï¼½ d, P<0.05), and improvement of the maximum urinary flow rate, which was increased from (7.9±3.7) ml/s preoperatively to (16.8±4.3) ml/s at 3 months after surgery in the HoLEP group and from (8.6±3.2) ml/s to (14.6±4.3) ml/s in the TURP group (P<0.05). CONCLUSIONS: Both TURP and HoLEP can improve bladder function and detrusor overactivity in BPH patients, with similar effects in improving urination at 3 to 6 months after surgery. However, HoLEP has more advantages over TURP during the period of postoperative recovery.

An energy efficient MAC protocol for multi-hop swallowable body sensor networks.

Swallowable body sensor networks (BSNs) are composed of sensors which are swallowed by patients and send the collected data to the outside coordinator. These sensors are energy constraint and the batteries are difficult to be replaced. The medium access control (MAC) protocol plays an important role in energy management. This paper investigates an energy efficient MAC protocol design for swallowable BSNs. Multi-hop communication is analyzed and proved more energy efficient than single-hop communication within the human body when the circuitry power is low. Based on this result, a centrally controlled time slotting schedule is proposed. The major workload is shifted from the sensors to the coordinator. The coordinator collects the path-loss map and calculates the schedules, including routing, slot assignment and transmission power. Sensor nodes follow the schedules to send data in a multi-hop way. The proposed protocol is compared with the IEEE 802.15.6 protocol in terms of energy consumption. The results show that it is more energy efficient than IEEE 802.15.6 for swallowable BSN scenarios.

Predicting prognosis and drug sensitivity in bladder cancer: an insight into Pan-programmed cell death patterns regulated by M6A modifications.

The team aimed to explore the possible functional significance of M6A regulation in Pan-programmed cell death (PCD) among patients with bladder cancer (BLCA). In BLCA patients, the analysis was conducted on the13 patterns of programmed cell death (PCD) and the regulation of M6A. Transcriptome, genomics, and clinical data were collected from TCGA-BLCA, GEO32548, and IMvigor210. Consensus clustering analysis, functional enrichment analysis, and other prognostic tools were used to validate the Pan-PCD. Finally, in vitro experiments and transcription sequencing were performed to understand the potential influence of the PI3K pathway on Pan-PCD in BLCA patients. Diverse PCD patterns were simultaneously activated, and M6A regulators exhibited significant variability in bladder malignant tissues. The machine learning algorithm established an 8-gene M6A-related Pan-PCD signature. This signature was validated in three independent datasets, and BLCA patients with higher risk scores had worse prognosis. An unsupervised clustering approach identified activated and suppressed Pan-PCD subgroups of BLCA patients, with distinct responses to immunotherapy and drug sensitivity. In addition, the PI3K pathway was identified as a key mechanism for various forms of programmed cell death, encompassing apoptosis, pyroptosis, autophagy, and cell death dependent on lysosomes. This research revealed that the Pan-PCD model was a more promising approach for BLCA patients under M6A regulation. A new signature from M6A-related Pan-PCD was proposed, with prognostic value for survival or drug sensitivity. The PI3K pathway was a key mechanism for multiple PCDs in BLCA patients.

ALS-linked C9orf72 dipeptide repeats inhibit starvation-induced autophagy through modulating BCL2-BECN1 interaction.

Growing evidences indicate that dysfunction of autophagy contributes to the disease pathogenesis of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), two neurodegenerative disorders. The GGGGCC·GGCCCC repeat RNA expansion in chromosome 9 open reading frame 72 (C9orf72) is the most genetic cause of both ALS and FTD. According to the previous studies, GGGGCC·GGCCCC repeat undergoes the unconventional repeat-associated non-ATG translation, which produces dipeptide repeat (DPR) proteins. Although there is a growing understanding that C9orf72 DPRs have a strong ability to harm neurons and induce C9orf72-linked ALS/FTD, whether these DPRs can affect autophagy remains unclear. In the present study, we find that poly-GR and poly-PR, two arginine-containing DPRs which display the most cytotoxic properties according to the previous studies, strongly inhibit starvation-induced autophagy. Moreover, our data indicate that arginine-rich DPRs enhance the interaction between BCL2 and BECN1/Beclin 1 by inhibiting BCL2 phosphorylation, therefore they can impair autophagic clearance of neurodegenerative disease-associated protein aggregates under starvation condition in cells. Importantly, our study not only highlights the role of C9orf72 DPR in autophagy dysfunction, but also provides novel insight that pharmacological intervention of autophagy using SW063058, a small molecule compound that can disrupt the interaction between BECN1 and BCL2, may reduce C9orf72 DPR-induced neurotoxicity.

Prognostic significance and mechanisms of CXCL genes in clear cell renal cell carcinoma.

This study aimed to investigate the clinical significance, biological functions, and underlying mechanisms of CXCL genes in clear cell renal cell carcinoma (ccRcc) based on patient datasets and pan-cancer analysis. The interaction between CXCL genes in ccRcc and immune components, particularly in relation to neutrophil recruitment and polarization mechanisms, was also evaluated. Furthermore, a risk score was developed using a signature for neutrophil polarization. The role of CXCL2 was assessed through in vitro experiments. Results showed that five CXCL genes (CXCL 2, 5, 9, 10, and 11) were upregulated in renal cancer tissue, while seven genes (CXCL 1, 2, 3, 5, 8, 13, and 14) significantly impacted patient survival. Moreover, CXCL 1, 5, and 13 affected progression-free survival. Besides, differences in mRNA expression and immune components affected renal cancer outcomes. Furthermore, three pairs of CXCL gene-immune cell interactions (CXCL13-CD8+ T cells, CXCL9/10-M1 cells, CXCL1/2/3/8-neutrophils) were identified through single-cell and pan-cancer analysis. A TAN risk score with prognostic value for KIRC patients was constructed using 11 genes and a TAN signature. Neutrophil polarization significantly impacted survival. Notably, CXCL2 was involved in neutrophil recruitment and polarization, thus promoting ccRcc progression. In conclusion, seven prognostic CXCL genes (CXCL 1/2/3/5/8/13/14) for ccRcc patients and three pairs of CXCL gene-immune cell interactions were identified. Furthermore, results showed that CXCL 2 promotes ccRcc progression through neutrophil recruitment and polarization.

Chlorpromazine affects autophagy in association with altered Rag GTPase-mTORC1-TFEB signaling.

Autophagy is a critical protein and organelle quality control system, which regulates cellular homeostasis and survival. Growing pieces of evidence suggest that autophagic dysfunction is strongly associated with many human diseases, including neurological diseases and cancer. Among various autophagic regulators, microphthalmia (MiT)/TFE transcription factors, including transcription factor EB (TFEB), have been shown to act as the master regulators of autophagosome and lysosome biogenesis in both physiological and pathological conditions. According to the previous studies, chlorpromazine (CPZ), an FDA-approved antipsychotic drug, affects autophagy in diverse cell lines, but the underlying mechanism remains elusive. In our present study, we find that CPZ treatment induces TFEB nuclear translocation through Rag GTPases, the upstream regulators of mechanistic target of rapamycin complex 1 (mTORC1) signaling. Meanwhile, CPZ treatment also blocks autophagosome-lysosome fusion. Notably, we find a significant accumulation of immature autophagosome vesicles in CPZ-treated cells, which may impede cellular homeostasis due to the dysfunction of the autophagy-lysosome pathway. Interestingly and importantly, our data suggest that the expression of the active form of Rag GTPase heterodimers helps in reducing the accumulation of autophagosomes in CPZ-treated cells, further suggesting a major contribution of the Rag GTPase-mTORC1-TFEB signaling axis in CPZ-induced autophagic impairment.

Fatty acid metabolism-related signature predicts survival in patients with clear cell renal carcinoma.

OBJECTIVE: To explore fatty acid metabolism-related genes and signature, which could predict survival outcomes of clear cell renal carcinoma (ccRCC) patients. MATERIALS AND METHODS: Transcriptional and survival data of fatty acid genes in ccRCC patients were retrieved from UCSC Xena and Geo DataSets. We first performed Lasso Cox regression analysis to identify survival-related genes. These genes were then used to construct metabolic-related gene signature and risk score. Enrichment analysis and immune component and chemotherapy response prediction were also performed. RESULTS: In total, five survival-related genes were identified: AGR2, HAO2, IGF2BP1, MCCD1 and OLFM4 (p < 0.05). A series of survival value analyses revealed survival-related signature and risk score, including KM analysis (training set: p < 0.001; test set: p = 0.008). Four clinical indexes (T stage, N stage, M stage, and pathology) were positively correlated with risk score. Time-dependent ROC analysis yielded AUC value of 0.813. Immune landscape analysis revealed that risk score was strongly correlated with TAM score and cytotoxic score. Patients with high risk score and TAM score or cytotoxic score had the shortest survival time. Finally, inhibition of fatty acid metabolism in human ccRCC cell line produced corresponding changes in five genes, consistent with our preliminary results. CONCLUSION: We identified five survival-related genes (AGR2, HAO2, IGF2BP1, MCCD1 and OLFM4) in ccRCC patients. Our results also indicated that survival-related signature based on these genes is a potential robust prognostic biomarker for ccRCC in patients.

Comprehensive analysis of expression profiles and prognosis of TRIM genes in human kidney clear cell carcinoma.

OBJECTIVE: To determine survival rates and the underlying mechanism of genes in the TRIM family in Kidney Clear Cell Carcinoma (KIRC). METHODS: Transcriptional and survival data of TRIM genes in KIRC patients were retrieved from the UCSC Xena, and GEPIA databases. The function of TRIM genes in KIRC was investigated, focusing on potential ubiquitination, miRNAs regulation, and enrichment analysis. Next, TRIM gene survival values were determined, followed by the development of a survival-related signature. RESULTS: Only TRIM26 was down expressed in the carcinoma tissue and had a survival value in KIRC relative to control tissues, which was supplied by vitro experiment. The patients with lower expression of TRIM26 would have the chance to live a shorter time. SNRPB, which also plays a role in ubiquitination, directly interacted with TRIM26. Moreover, two miRNAs (hsa-let-7i-5p, and hsa-miR-1228-5p) that regulated levels of TRIM26 expression were also identified. Next, we constructed a signature (TRIM4/7/27/58/65/72) and found that high-risk scores of the signature were associated with poor survival rates in KIRC patients. while its resultant risk scores were correlated with immune cell components and markers. CONCLUSIONS: TRIM26 was differentially expressed between KIRC and normal tissues and had a survival value in the KIRC. hsa-let-7i-5p/hsa-miR-1228-5p-TRIM26-SNRPB was a potential mechanism axis that may play a role on the KIRC cells. A survival signature (TRIM4/7/27/58/65/72) was successfully established to predict the survival of KIRC patients.

The clinical value of indocyanine green fluorescence navigation system for laparoscopic partial nephrectomy in the case of complex renal clear cell carcinoma (R.E.N.A.L score ≥7).

Objective: We demonstrated the potential clinical utility of the indocyanine green (ICG) fluorescence navigation system for laparoscopic partial nephrectomy in the case of complex renal clear cell carcinoma (R.E.N.A.L score ≥7). Methods: Compared with the general laparoscopic partial nephrectomy and ICG fluorescence laparoscopic partial nephrectomy, a series of indicators were analyzed: the basic information like age, sex, and the tumor location; the operative information like the time of renal ischemia, the blood loss, and the complications; and other important indexes like the renal function, the volume of the tumor, and the weight of the specimens. Results: 60 patients were included in this study. 21 patients in the group of fluorescence laparoscopy, and 39 patients in the group of general laparoscopy. There was no statistical difference for most indexes except the renal function. Preoperative serum creatinine was close (82.4±11.7 vs. 77.5±12.7, mmol/l, p=0.15). However, the patients in the group of fluorescence laparoscopy got a smaller serum creatinine growth degree (12.9±5.3 vs. 17.9±7.3, mmol/l, p=0.008), and a less decreasing level of GFR (16.5±6.4 vs. 24.4±9.8, mL/(min*1.73m2), p=0.001) after the operation. In addition, the average volume of the tumor (28.8±9.8 vs. 26.9±8.2, cm3, p=0.43) and the weight of the specimens (32.3±10.4 vs. 33.9±8.9, g, p=0.52) were no statistical difference. But the group of fluorescence laparoscopy had a smaller ratio of the weight/ the volume (1.13±0.06 vs. 1.28±0.10, g/cm3, p<0.001). And the two groups had a similar test-positivity rate of surgical margins (p=0.19). Conclusion: Without increasing the rate of positive surgical margins, ICG fluorescence navigation system for laparoscopic partial nephrectomy for complex renal clear cell carcinoma could conserve more normal renal tissue.

Ultrasonography-assisted flexible ureteroscope for the treatment of parapelvic renal cysts: A comparison between the 1470-nm diode laser and the holmium laser.

The present study aimed to compare the efficacy and safety of a flexible ureteroscopic holmium laser incision with flexible ureteroscopic 1470-nm diode laser incision for the treatment of parapelvic renal cysts. The current study collected and analysing the clinical data of 90 independent renal cysts cases retrospectively, including 43 renal cysts cases that received holmium laser surgery (holmium laser group) and 47 renal cysts cases that received 1470-nm diode laser surgery (1470-nm diode laser group). Each group was divided into a thin-walled cyst subgroup and thick-walled cyst subgroup according to cyst wall thickness. Intracapsular hematoma was significantly lower in the 1470-nm diode laser group compared with the holmium laser group (0/47 vs. 4/43; P=0.048). The incision diameter in the 1470-nm diode laser group was significantly larger than the holmium laser group in the thick-walled parapelvic renal cysts subgroup [1.70(1.50,1.90) vs. 1.30(1.25,1.70) cm; P=0.007]. The renal cystic diameter of the two groups was markedly reduced one and six months after surgery. The difference was non-significant in the diameter of the renal cyst in the thin-walled cysts subgroups between the two laser groups 6 months after surgery (1.01±0.38 vs. 1.03±0.53 cm; P=0.454). However, the diameter of the renal cyst in the thick-walled cysts subgroup treated with the 1470-nm diode laser was significantly lower compared with the thick-walled cysts subgroup treated with the holmium laser 6 months after surgery (1.21±0.57 vs. 1.88±0.94 cm; P=0.002). The results demonstrated that the use of a 1470-nm diode laser or holmium laser surgery under a flexible ureteroscope is a safe and effective treatment for parapelvic renal cysts. For thick-walled parapelvic renal cysts, the 1470-nm diode laser appears to exhibit a lower postoperative recurrence rate and better long-term postoperative effects due to its improved haemostatic effect and larger intraoperative incision diameter.

An Immune-Related Signature Predicted Survival in Patients With Kidney Papillary Cell Carcinoma.

Immune-related genes are important factors in tumor progression. The main aim of this study was to identify the immune-related genes in kidney papillary cell carcinoma (pRCC) patients. We downloaded RNAseq data and clinical information of pRCC patients from the TCGA database and retrieved the immune-related genes list from Immport. From the data, we mined out 2,468 differential expression genes (DEGs) and 183 immune-related DEGs. Four hub DEGs (NTS, BIRC5, ELN, and CHGA) were identified after conducting Cox analysis and LASSO analysis. Moreover, the prognostic value of the signature based on four hub DEGs was verified using Kaplan-Meier analysis (P = 0.0041 in the training set and p = 0.021 in the test set) and ROC analysis (AUC: 0.957 in 1 year, 0.965 in 2 years, and 0.901 in 3 years in the training set, and 0.963 in 1 year, 0.898 in 2 years, and 0.742 in 3 years in the test set). Furthermore, we found that the high-risk score group had a higher percentage of B cells in the immune component, a higher expression of immune-related genes (CTLA4, LAG3, PDCD1LG2, and TIGIT), and a better immunotherapy response.

Efficacy and Complication of Flexible Ureteroscopic Holmium Laser Incision for Simple Renal Cysts: A Retrospective Study.

Objective: The aim of this research was to verify the efficacy and complication of flexible ureteroscopic holmium laser incision for simple renal cysts (SRCs). Patients and Methods: We retrospectively reviewed 116 patients who not only had done flexible ureteroscopic holmium laser incision or laparoscopic decortication for SRC in our institution but also had sufficient data: preoperative information and >1-year follow-up records. The following variables were recorded: age, gender, side, cyst size, location (upper pole, lower pole, and interpolar), blood loss, operative duration, complications during and after surgery, pathology report, and presence or absence of flank pain. The primary endpoint was the efficacy of the treatment; secondary endpoints were safety, pain, and the resolution of other complications. All patients underwent radiologic imaging of the kidneys with a repeated CT, before the operation, 3 and 12 months after surgery. If there were no cysts on the most recent imaging, we defined it as a radiologic success. Results: No statistically significant difference in the background variable in patients of group A (64 patients, flexible ureteroscopic holmium laser incision) and group B (52 patients, laparoscopic decortication) was found, including age, gender, cyst's side, cyst's location, and cyst size before the operation. There were less blood loss by surgeons' evaluation and shorter operative duration (p < 0.001) in group A. In group A, there were three patients who had failed in the first time of operation (two patients failed to place flexible ureteroscope through ureter because of ureteral stricture, and one patient was unable to find the renal cyst in the view of flexible ureteroscope), and no severe postoperative complication was observed. The number of postoperative radiologic failure was five at 3 months and three at 12 months in group A, whereas all the procedures were completed laparoscopically, and no conversion was necessary for group B. But there was one patient who had obvious hematuresis for 1 month after the operation and then it was resolved spontaneously at 3 months. There was only one patient who had a radiologic failure in group B, with the cyst of ∼2 cm at 3 months, and his cyst cannot be seen in CT imaging at 12 months without further treatment. There was no statistically significant difference in the rate of effective operation and complication between the two groups. Conclusion: The operation of flexible ureteroscopic holmium laser incision for SRC had the advantages of less blood loss, short operation time, with a similar rate of operative success and radiologic success after the operation, compared with the process of laparoscopic decortication. It was a good option for urologists to deal with endogenous renal cysts.

A Comparative Study on the Clinical Efficacy of Two Different Disposable Circumcision Suture Devices in Adult Males.

PURPOSE: We evaluated the safety and efficacy of two different kinds of disposable circumcision suture devices in adult men. MATERIALS AND METHODS: Adult male patients (n = 179; mean age: 23.7 years) with redundant prepuce and/or phimosis were included in a clinical trial from July 2015 to August 2016. Patients were divided into 2 groups: group A using the Langhe disposable circumcision suture device (n = 89), and group B using the Daming disposable circumcision suture device (n = 94). RESULTS: Intraoperative and postoperative bleeding were more serious in the group A of disposable circumcision suture device compared with the group B of disposable circumcision suture device (4.21 ± 1.31 ml) versus (2.56 ± 1.45 ml). Patients in the group B of disposable circumcision suture device had a longer swelling time (group A versus group B: 11.7 ± 0.9 days versus 14.5 ± 1.4 days), the postoperative pain score in the 7 days after surgery (group A versus group B: 2.9 ± 0.9 versus 3.8 ± 1.5), and higher postoperative infection rate (group A versus group B: 4.7% versus 13.8%), the differences were statistically significant (p < 0.05). CONCLUSION: postoperative complications of the two kinds of disposable circumcision suture devices are different. We should pay attention to the risk of postoperative bleeding when the patients use the Langhe disposable circumcision suture device, while the patients who use the Langhe disposable circumcision suture device will have a longer healing time, and postoperative pain and the risk of infection cannot be ignored after the surgery.
