Background: Tension-free vaginal tape-Abbrevo (TVT-A) and tension-free vaginal tape-Obturator (TVT-O) are the main procedures for the treatment of stress urinary incontinence (SUI) in females. This study investigated the clinical efficacy of TVT-A versus TVT-O for the treatment of SUI in elderly women.

Methods: A retrospective analysis was conducted on 126 cases of SUI in elderly female patients admitted to our hospital from January 2022 to January 2023. The patients were divided into TVT-A group (65 cases) and TVT-O group (61 cases) according to the surgical methods. Follow-up was conducted via outpatient examination and telephone. Perioperative conditions, surgical outcomes, postoperative complications and quality of life were analysed and compared between the two groups.

Results: No statistically significant difference in surgical time, intraoperative blood loss, indwelling catheter duration, average hospital days, bladder injury, urethral injury, incision infection, dysuria, cured rate and quality of life was found between the two groups (p > 0.05). The incidence of postoperative groin pain in the TVT-A group was significantly lower than that in the TVT-O group (p < 0.05).

Conclusions: The efficacy of TVT-A and TVT-O in treating SUI in older women is about the same. However, TVT-A is more minimally invasive, safer and has fewer complications.

Objective: Currently, the factors influencing poor drainage of ureteral stents after radical cystectomy with cutaneous ureterostomy are still unclear. Therefore, the aim of this study was to determine the risk factors for poor drainage of ureteral stents after radical cystectomy with cutaneous ureterostomy and to provide evidence for the prevention of this complication.

Methods: This retrospective study included 86 patients who underwent periodic replacement of ureteral stents following radical cystectomy with cutaneous ureterostomy between October 2017 and March 2024. The general data and related indicators of the patients were collected, the risk factors were identified through univariate and multivariate logistic regression analyses, and corresponding interventions were proposed.

Results: Among the 86 patients, 26 had poor drainage of ureteral stents, with an incidence rate of 30.23%, and no serious consequences occurred after timely and effective treatment. Univariate and multivariate logistic regression analyses revealed that body mass index (BMI) (p = 0.003, odds ratio (OR) = 2.909, 95% CI: 1.435-5.898), diabetes mellitus (p = 0.012, OR = 14.073, 95% CI: 1.770-111.889), urinary tract infection (p = 0.004, OR = 16.792, 95% CI: 2.402-117.411), and foreign body blockage (p = 0.048, OR = 5.277, 95% CI: 1.012-27.512) were independent risk factors for poor drainage of ureteral stents.

Conclusions: The incidence of poor drainage of ureteral stents after radical cystectomy with cutaneous ureterostomy is relatively high. Maintenance of a healthy weight, strict management of blood glucose levels, active prevention of urinary tract infections, and timely detection and removal of small foreign bodies that may be present are essential to prevent this complication.

Background: As a frequent disease, prostatic hyperplasia could be treated by transurethral resection of prostate (TURP). However, postoperative pain may affect the prognosis of patients to some extent, so exploring reasonable anaesthetic drugs is an important measure to reduce the recovery period of anaesthesia. This study used the combination of ropivacaine and nalbuphine for intraoperative anaesthesia in patients undergoing TURP to investigate its effect on pain during anaesthesia recovery.

Methods: A retrospective study was conducted on the clinical data of 205 patients with prostatic hyperplasia who underwent TURP in our hospital from June 2020 to December 2022. All patients experienced epidural anaesthesia, and 110 patients who used ropivacaine combined with nalbuphine were included in the study group, whereas 95 patients who used ropivacaine and lidocaine were classified as the control group. The Visual Analogue Scale was used to evaluate the pain conditions of patients. The levels of pain mediators, such as substance P (SP), bradykinin (BK) and histamine (HIS), the stress levels, including cortisol (Cort), adrenocorticotropic hormone (ACTH) and norepinephrine (NE), and the incidence of adverse reactions were compared between the two groups.

Results: At T0 (postoperative 30 min), T1 (postoperative 60 min), T2 (postoperative 2 h) and T3 (postoperative 4 h), the study group had significantly lower pain scores (p < 0.01), levels of SP, BK and HIS (p < 0.001), and levels of Cort, ACTH and NE (p < 0.05) than the control group. No statistical difference was observed in the incidences of adverse reactions between the two groups (p > 0.05).

Conclusions: The combination of ropivacaine and nalbuphine has a notable analgesic effect during anaesthesia recovery in patients undergoing TURP. It inhibits the secretion of pain and physical stress indicators and relieves postoperative pain to a large extent.

Objective: Hospital-acquired urinary tract infections (UTIs) are common complications in patients with diabetic nephropathy (DN), leading to increased mortality and increased medical resource utilisation. This study investigated hospital-acquired UTIs in patients with DN, focusing on prevalent pathogens and drug resistance to inform clinical management.

Methodology: This retrospective study analysed 141 patients with hospital-acquired UTIs admitted to The Affiliated Hospital of Qingdao University from January 1, 2013 to December 31, 2022, using the Yidu Cloud database. Among them, 109 had DN, and 32 had nondiabetic nephropathy (NDN). Patient demographics, pathogen distribution, and antibiotic resistance were statistically evaluated.

Results: The incidence of hospital-acquired UTIs was significantly higher in patients with DN compared to those with NDN (p < 0.0001), with a higher prevalence in women (p = 0.004). Gram-negative bacteria, particularly Escherichia coli (E. coli) and Klebsiella pneumoniae, were the primary pathogens in patients with DN and NDN. E. coli infections were more common in the DN group (p = 0.017). These pathogens exhibited high susceptibility to carbapenems, β-lactamase inhibitors, amikacin, nitrofurantoin, and minocycline; However, they showed significant resistance to quinolones, cephalosporin, and penicillins.

Conclusions: Preventing hospital-acquired UTIs in patients with DN is crucial. Effective treatment requires selecting antibacterial drugs based on pathogen resistance profiles.

Background: Acute immune rejection remains a challenge in the post-transplant period, with approximately 7.8% of renal transplant recipients experiencing rejection episodes within the first year. Genetic polymorphisms in the CYP3A5 gene, which influences tacrolimus metabolism, have garnered interest regarding their association with clinical outcomes in renal transplantation.

Methods: This retrospective correlation study analysed clinical data from kidney transplant patients who received tacrolimus treatment at our hospital from June 2015 to June 2023. The presence of CYP3A5 gene polymorphisms, tacrolimus trough levels, and demographic and clinical data were collected and analysed.

Results: A total of 105 kidney transplant patients were included. Patients were divided into acute immune rejection (n = 56) and non-acute immune rejection (n = 49) groups. The distribution of CYP3A5 gene polymorphisms differed significantly between the acute rejection and non-acute rejection groups (p = 0.037). The acute rejection group exhibited a higher frequency of CYP3A5 ^*1/^*1 or ^*1/^*3 genotypes than the non-acute rejection group. No statistically significant differences were found in the tacrolimus trough levels between the two groups. Correlation analysis revealed a statistically significant correlation between CYP3A5 gene polymorphism and post-transplant acute immune rejection (r = 0.223, p < 0.05).

Conclusions: This study demonstrated a significant association between CYP3A5 gene polymorphism and the risk of post-transplant acute immune rejection in renal transplant recipients receiving tacrolimus therapy. These findings highlighted the importance of genetic variability in tacrolimus metabolism when managing immunosuppressive therapy in transplant recipients.

Background: Urinary tract infections (UTIs) are prevalent amongst paediatric patients, and they can lead to emergency department (ED) visits. A subset of patients requires a second ED visit, creating a burden on healthcare resources. This study aimed to shed light on the clinical, laboratory, treatment-related and environmental determinants associated with the recurrence of ED visits in this specific paediatric population.

Methods: This single-centre retrospective study involved paediatric patients diagnosed with UTIs and admitted to the paediatric ED of our hospital from September 2021, to August 2023. In accordance with whether a second visit was required, the ED patients were grouped into non-second-visit group or second-visit group. The demographic, clinical, laboratory, diagnostic, and environmental factors were analysed in detail. Statistical analyses, including chi-square tests, t-tests and correlation analyses, were employed to assess the associations between various factors and subsequent ED visits.

Results: A total of 357 patients, including 324 patients without a second visit and 33 patients with a second visit, were included in this study. Factors significantly associated with second ED visits included fever (≥38.5 ^°C) at initial presentation (p = 0.034), longer symptom duration (p = 0.022), increased C-reactive protein (CRP) levels (p = 0.018), hydronephrosis (p = 0.033) and lack of oral antibiotic use before the first visit (45.45% vs. 67.9%, p = 0.017). More bubble bath exposure (p = 0.037) and lower consultation rates with paediatric urology services (p = 0.020) were associated with repeated visits. Multifactor logistic regression analysis showed that the factors significantly associated with second ED visits were longer symptoms duration, fever (≥38.5 ^°C) at initial presentation, presence of flank pain, increased CRP levels, hydronephrosis, renal stones, vesicoureteral reflux, underlying anatomical abnormalities, lack of oral antibiotic use before the first visit, bubble bath exposure and lower consultation rates with paediatric urology services.

Conclusions: A series of clinical indicators, laboratory findings, diagnostic measures and environmental factors may be associated with the need for a second ED visit amongst paediatric patients with UTI. Early antibiotic intervention, identification of underlying anatomical anomalies and management of environmental exposures may mitigate recurrent ED visits.

Objective: Changes in glucolipid metabolism parameters in patients undergoing renal transplantation (RT) and their influences on the incidence of postoperative complications were analysed. The objective was to provide a reference for clinical practice and reliable and safe implementation of RT.

Methods: A total of 131 patients treated with RT at our institution from January 2019 to March 2024 were selected for retrospective analysis: 71 patients who developed postoperative complications (research group) and 60 patients who did not (control group). Differences in fasting plasma glucose (FPG), glycosylated haemoglobin (HbA1c), total cholesterol (TC) and triglyceride (TG) levels before and three days after surgery were compared, and their predictive value for postoperative complications was analysed. In addition, relevant factors influencing complications after RT were identified.

Results: HbA1c level changed significantly in neither group after surgery (p > 0.05), but FPG, TG and TC levels increased in both groups (p < 0.05). Differences in FPG and TC levels before and after surgery were larger than those in the control group (p < 0.05). The receiver operating characteristic curve revealed the excellent diagnostic value of differences in FPG and TC levels for postoperative complications, and logistic regression analysis indicated that such differences were independent risk factors for complications after RT (p < 0.05).

Conclusions: The early evaluation of postoperative complications can be achieved by monitoring differences in FPG and TC levels before and after RT, allowing for the timely formulation and implementation of interventions.

Background: Early diagnosis of postoperative acute kidney injury (AKI) is crucial. This study investigated the changes and early diagnostic value of Doppler ultrasound parameters in patients with AKI after laparoscopic radical prostatectomy (LRP).

Methods: This study retrospectively analysed the clinical data of 198 patients with LRP undergoing Doppler ultrasound from May 2020 to May 2022. The incidence of AKI after LRP was measured based on diagnostic criteria of AKI developed by Kidney Disease: Improving Global Outcomes. The patients were divided into AKI group (n = 12) and non-AKI group (n = 186) in accordance with the presence or absence of AKI. This study compared changes in Doppler ultrasound parameters between two groups, and evaluated the clinical efficacy of single and combined diagnosis of ultrasound parameters using receiver operating characteristic (ROC) curve and area under the curve (AUC).

Results: Twelve patients experienced postoperative AKI, with an incidence rate of 6.06%. No significant difference was found in baseline data, serum creatinine (Scr), urinary output and blood potassium levels of both groups (p > 0.05). The urinary output 1 day after surgery was significantly lower than that before surgery (p < 0.05). The AKI group demonstrated higher pulsatility index (PI) and resistive index (RI) of the renal interlobar artery than the non-AKI group (p < 0.05), with no significant difference in peak systolic velocity (PSV) in both groups (p > 0.05). No significant difference was observed in the Doppler ultrasound parameters of renal segmental artery and main renal artery (p > 0.05). The AUCs in the PI of the renal interlobar artery, the RI of the renal interlobar artery, and the combined diagnosis were 0.720, 0.704 and 0.724, respectively. ROC curve showed that the above two Doppler ultrasound parameters had good diagnostic efficacy for AKI after LRP (p < 0.05).

Conclusions: The PI and RI of renal interlobar artery in the AKI group after LRP were significantly different from those in the non-AKI group. These two Doppler ultrasound parameters had good diagnostic efficacy in the early identification of AKI after LRP. Thus, they could provide reference and guidance for clinical practice.
