Purpose:
Urodynamic studies (UDS) are the gold standard for evaluating pediatric lower urinary tract dysfunction (LUTD). However, previous studies have shown that the interpretation of cystometric findings may vary according to the observer’s level of experience and the criteria used for evaluation. This study aimed to investigate interobserver differences in the reporting of cystometric parameters in children with spina bifida.
Methods:
Patients who underwent UDS between 2020 and 2025 for neurogenic LUTD secondary to spina bifida were retrospectively reviewed. Studies that did not reach 80% agreement for compliance with good urodynamic practice standards were excluded. Detrusor overactivity (DOA) and bladder compliance were independently evaluated by 4 pediatric urologists and 3 urologists experienced in neuro-urology. Agreement was assessed using Fleiss’ kappa test.
Results:
A total of 100 children, including 53 females and 47 males, were included; the median age was 6.5 (range, 1–17) years. Agreement of at least 80% was reached in 86% of evaluations for DOA and 82% of evaluations for compliance. Based on the ratings of 7 observers, the Fleiss’ kappa value was 0.60 for DOA, indicating moderate agreement, and 0.46 for bladder compliance, indicating weak agreement.
Conclusions
This study demonstrated substantial interobserver variation in the interpretation of UDS, even among experienced centers and observers. Because UDS are essential for the diagnosis, treatment, and follow-up of patients with spina bifida, standardized criteria are needed to improve interobserver consistency in this patient group. Multicenter prospective studies involving observers with varying levels of experience are warranted to improve concordance in UDS reporting.

Purpose:
Real-world evidence comparing surgical techniques for symptomatic hemorrhoidal disease (HD) remains limited, despite the availability of multiple approaches. This study aimed to evaluate short-term, interim outcomes from a prospective, nationwide cohort study that compared the effectiveness of different operative techniques based on patient-reported outcome measures (PROMs) in patients with symptomatic HD.
Methods:
A prospective, nationwide cohort study was conducted at 20 tertiary care centers across Turkiye between July 2022 and July 2024. Adult patients aged 18 years or older with symptomatic HD (grades I–IV) who underwent surgery during this period were included. The choice of procedure was determined by the operating surgeon, and patients were categorized into excisional, fixative, and ablative groups according to the surgical approach used. The primary outcomes were changes in the Hemorrhoidal Disease Symptom Score, Short Health ScaleHD, visual analog scale for pain, and patient satisfaction, assessed from the preoperative period to postoperative day 7 and postoperative week 6.
Results:
The study included a total of 315 patients after excluding those who did not fulfil the inclusion criteria. Among them, 239 (78.9%) were male, with a mean age of 43.7±11.7 years. The distribution of patients across surgical groups was 207 (65.7%) in the excisional group, 30 (9.5%) in the fixative group, and 78 (24.8%) in the ablative group. All groups demonstrated significant improvements in PROM scores from preoperative to postoperative assessments. However, no statistically significant differences were observed between groups at any time point for PROM scores or for changes in PROM scores across consecutive evaluations (P≥0.05 for all comparisons). Urinary retention occurred more frequently, and hospital stays were longer in the fixative group (P=0.006 and P<0.001, respectively). The excisional group had a greater need for narcotic use and longer duration of use (P=0.003 and P<0.001, respectively).
Conclusion
This real-world cohort study shows that all 3 surgical approaches are effective for HD, providing comparable short-term symptomatic relief and patient satisfaction. These techniques appear equally valid treatment options, and the choice of procedure may best be individualized based on patient-specific characteristics and surgeon preference.Trial registration: ClinicalTrials.gov identifier: NCT05429060

PURPOSE: To investigate the pathophysiological role of superoxide anion and total reactive oxygen species (ROS) production by the spermatozoa of men with varicocele and its relationship with varicocele grade and semen parameters. MATERIALS AND METHODS: This prospective study included 34 men with grade II–III varicocele, regardless of their fertility status. The control group consisted of 13 healthy men. Semen characteristics were examined according to the 2010 World Health Organization criteria. The swim-up method was used for sperm preparation. Total ROS and superoxide anion production was assayed by luminol- and lucigenin-dependent chemiluminescence (CL), respectively. RESULTS: The men with varicocele had significantly higher total ROS and superoxide anion levels than the healthy control subjects (2.9±0.4 relative light unit (RLU) vs. 2.4±0.1 RLU, p=0.001 for luminol-dependent CL and 2.8±0.4 RLU vs. 2.3±0.2 RLU, p=0.002 for lucigenin-dependent CL). Cases of grade III varicocele had significantly higher superoxide anion and total ROS levels than grade II cases and control subjects (p < 0.001). Superoxide anion and total ROS levels were negatively correlated with all semen parameters. CONCLUSIONS: The superoxide anion levels produced by spermatozoa were significantly higher in varicocele patients than in control subjects. ROS production was related to increased varicocele grade, impaired semen concentration, and abnormal morphology in men with varicocele. Our findings suggest that superoxide anion overproduction may be an important step in the cascade of ROS-related damage to spermatozoa, resulting in impaired semen parameters in patients with varicocele.

OBJECTIVES: The aim of this study is to investigate the efficacy of locally applied insulin-like growth factor 1 (IGF-1) on the recovery of facial nerve functions after crush injury in a rabbit model. METHODS: The rabbits were randomly assigned into three groups. Group 1 consisted of the rabbits with crush injury alone; group 2, the animals applied saline solution onto the crushed facial nerve and group 3, IGF-1 implemented to the nerve in the same manner. Facial nerve injury was first electrophysiologically studied on 10th and 42nd days of the procedure. The damage to the facial nerves was then investigated histopathologically, after sacrification of the animals. RESULTS: In the electrophysiological study, compound muscle action potential amplitudes of the crushed nerves in the second group were decreased. In pathological specimens of the first and second groups, the orders of axons were distorted; demyelination and proliferation of Schwann cells were observed. However, in IGF-1 treated group axonal order and myelin were preserved, and Schwann cell proliferation was close to normal (P < 0.05). CONCLUSION: Local application of IGF-1 in a slow releasing gel was found efficacious in the recovery of the facial nerve crush injury in rabbits. IGF-1 was considered worthy of being tried in clinical studies in facial nerve injury cases.

Present report describes a 46 year old male patient with a diagnosis of major depression who developed tardive dyskinesia during bupropion therapy. Our patient had no history of neuroleptic use and his laboratory and neurologic examinations were normal. He had no family history of neurologic diseases. Although bupropion induced dyskinesia has been previously reported in the literature, it is rare and our case is the first case regarding tardive dyskinesia.
