Familial primary nocturnal enuresis (FPNE) is common in clinical practice and has shown an obvious familial aggregation that is associated with genetic factors.It has been found that chromosomes 4, 8, 12, 13 and 22 are related to the inheritance of enuresis. PRDM13 and EDNRB genes are related to the pathogenesis of enuresis, but the specific functions remain unclear.FPNE accounts for a high proportion in patients with refractory enuresis.Compared with other types of primary enuresis, FPNE is not difficult to be diagnosed, as long as the related family members have enuresis, it can be diagnosed as FPNE.Due to treatment difficulties, FPNE easily lasts into adulthood, serving as a type of intractable enuresis.Therefore, early diagnosis and active intervention should be made for children with FPNE.In this review, the epidemiology, pathogenesis, diagnosis and treatment of FPNE were summarized, aiming to provide references for improving the clinical diagnosis and treatment of FPNE.

Objective To investigate the value of urodynamic study(UDS)in guiding the treatment of lower urinary tract dysfunction(LUTD)in elderly patients with ischemic stroke(IS)during convalescence,in order to provide reference for clinical treatment.Methods A total of 50 LUTD patients with IS who were admitted to the First Affiliated Hospital of Xinxiang Medical University during Jan.2020 and Jan.2022 were selected.Oral tolterodine was administered to patients with detrusor overactivity(DO),clean intermittent catheterization(CIC)to those with no detrusor reflex and symptomatic increased residual urine,and oral administration of tamsulosin to those with functional obstruction of bladder outlet.The lower urinary tract symptoms(LUTS)relief rate,UDS parameters and quality of life(QoL)scores were compared before treatment and 3 months after treatment.Results The UDS examination results showed that 25 cases(50.0％)had simple DO,9 cases(18.0％)had DO with impaired detrusor muscle contraction function,5 cases(10.0％)had DO with bladder outlet functional obstruction,4 cases(8.0％)had no detrusor reflex,and 7 cases(14.0％)had simple bladder outlet functional obstruction.After 3 months of treatment,the symptoms of LUTS,including frequent urination,urgent urination,incontinence,dysuria and urinary retention were significantly improved(P＜0.05).The maximum urine flow rate and urine output were significantly increased,the residual urine volume was significantly reduced,QoL scores were significantly reduced,with significant differences(P＜0.001).Conclusion UDS is significant in guiding the treatment of LUTD in elderly patients with IS during convalescence.

【Objective】 To investigate the current situation and related factors of emotional and behavioral problems in children with diurnal urinary incontinence (DUI), in order to provide reference for clinical treatment and psychological intervention. 【Methods】 During Sep.2019 and Mar.2020, a survey was conducted in six primary schools in a county of Henan Province using the method of cluster sampling. The survey included general data and current DUI and urination-related problems, Strengths and Difficulties Scale (SDQ), and Pittsburgh Sleep Quality Index (PSQI). 【Results】 Of the 4 500 questionnaires distributed, 4 120 were collected, and 3 912 were qualified for statistical analysis. The overall prevalence of DUI was 3.6%. The detection rate of abnormal emotion and behavior in the DUI group was 48.2%, which was significantly higher than that in the non-DUI group (12.6%) (P<0.05). The scores of emotional symptoms, conduct problems, hyperactivity, peer communication problems and SDQ were significantly higher in the DUI group than in the control group (P<0.05). The results of multivariate analysis showed that gender, academic achievement, DUI times, caregivers, caregivers’ education level, family education style and sleep disorder were influencing factors of emotional and behavioral problems in DUI children (P<0.05). The total score of SDQ was positively correlated with the total score of PSQI (P<0.05). 【Conclusion】 The detection rate of emotional and behavioral abnormalities is high in DUI children, which is related to gender, academic achievement, DUI times, caregivers, education level of caregivers, family education style and sleep disorders.

[Objective] To investigate the impacts of voiding positions on urinary flow measurement (UFM) and post voided residual (PVR) in young males, to explore a better voiding position, and to provide reference for the clinical application of UFM. [Methods] A total of 43 male medical students (22-28 years old, all healthy with no lower urinary tract symptoms) from the First Affiliated Hospital of Xinxiang Medical College were enrolled.UFM was recorded in standing position, forward-bentding sitting position and sitting position, respectively.PVR was determined with B-ultrasound immediately after each voiding.Voided volume (VV), maximum urine flow rate (Qmax), average urine flow rate (Qave) and PVR were compared. [Results] In the standing, forward-bending sitting, and seating positions the VV were 211.6 (169.5, 265.9) mL, 206.8 (173.5, 262.8) mL, and 203.7 (175.9, 260.0) mL, respectively, with no significant difference (P=0.486); the Qmax were (26.00±2.33) mL/s, (26.41±2.12) mL/s, and (23.50±2.52) mL/s, respectively; the Qave were (14.03±2.21) mL/s, (14.27±2.18) mL/s, and (11.77±1.89) mL/s, respectively; the PVR were (9.97±2.26) mL, (9.43±1.97) mL and (12.10±3.28) mL, respectively.The Qmax and Qave in standing position and forward-bending sitting position were significantly higher than those in the sitting position, while the PVR was lower than that in the sitting position, with statistically significant difference (P<0.05). There were no significant differences in Qmax, Qave and PVR between the forward-bending sitting and standing positions (P>0.05). [Conclusion] Standing position and forward-bending seating position are beneficial for emptying the bladder, and these two positions are recommended for young men to urinate as the first choice.

Objective: To explore the changes of mechanosensitive channels Piezos (Piezo 1 and Piezo 2) in neurogenic bladder (NB) of young rats and their effects，so as to provide reference for clinical search of new therapeutic targets. Methods: A total of 30 female young SD rats were divided into 5 groups based on random number table method：sham operation group (sham)，2-week nerve transection group (NB-2W)，6-week nerve transection group (NB-6W)，2-week nerve transection + Piezos inhibitor group (NB-P-2W) and 6-week nerve transection + Piezos inhibitor group (NB-P-6W)，with 6 rats in each group.The NB models were constructed by transecting the L6 and S1 spinal nerves of young rats.The NB-2W and NB-6W groups were not intervened after modeling，while the NB-P-2W and NB-P-6W groups were intraperitoneally injected with Piezos inhibitor GsMTx4 (10 mg/kg) every 2 days after modeling.Bladder cystometry and ultrasound were performed after 2 and 6 weeks of transection.The expressions of Piezos and fibrosis-related indexes (Collagen Ⅰ and α-smooth muscle actin) were detected in bladder tissues. Results: The results of bladder cystometry showed that the basal bladder pressure in NB-2W group was significantly increased，while it was slightly decreased but was still higher in NB-6W group than in the sham group (P<0.05).Basal bladder pressure was lower in NB-P-2W group than in NB-2W group，but was higher than that in the sham group; basal bladder pressure was lower in NB-P-6W group than in NB-6W group，but higher than that in the sham group (P<0.05).Compared with the sham group，the NB-2W and NB-6W groups had firstly increased and then decreased maximum cystometric capacity (MCC) (P<0.05).Compared with NB-2W group，NB-P-2W group had lower bladder leakage point pressure (BLPP)，but higher MCC and bladder compliance (BC) (P<0.05).Compared with NB-6W group，NB-P-6W group had significantly lower BLPP but higher MCC and BC (P<0.05).HE and MASSON staining and ultrasound results showed that，with the extension of nerve transection time，bladder fibrosis gradually worsened，the bladder wall became rough and thickened，calculi were visible inside，and hydronephrosis gradually appeared; the degree of fibrosis in NB-P-2W and NB-P-6W groups was less than that in NB-2W and NB-6W groups，and no hydronephrosis was observed in the upper urinary tract.In addition，Western blotting and immunohistochemical results showed that NB-2W and NB-6W groups had significantly higher relative expression levels of Piezos，Collagen Ⅰ and α-SMA than the sham group (P<0.01)，while NB-P-2W and NB-P-6W groups had lower relative expression levels of Piezos,Collagen Ⅰ and α-SMA than NB-2W and NB-6W groups (P<0.01). Conclusion: The increased expressions of mechanosensitive channels Piezos in NB young rats may be involved in the progression of bladder fibrosis，but its mechanism needs further study.

【Objective】 To analyze the related factors of emotional and behavioral abnormalities in children with overactive bladder (OAB). 【Methods】 OAB children (aged 6 to 16 years) in a survey of 5 032 children from a county in Henan Province during Sep.2022 and Dec.2022 were identified and surveyed with Overactive Bladder Symptom Score (OABSS), Strength and Difficulties Questionnaire (SDQ) and Pediatric Sleep Questionnaire (PSQ). According to the SDQ score, they were divided into abnormal group (SDQ≥20) and normal group. 【Results】 There were 35.7%(137/385) cases in the abnormal group and 64.3% (248/385) in the normal group. Gender, education level of caregivers, body mass index (BMI), age, constipation, enuresis and severity of OAB were significantly associated with emotional and behavioral abnormalities (P<0.05). Children in the abnormal group showed significant differences in emotional symptoms, conduct problems, hyperactivity symptoms, peer interaction and sleep (P<0.001). Multivariate regression analysis revealed significant differences in gender, educational level of caregi-vers, BMI, age, constipation, enuresis, severity of OAB and PSQI between the two groups (P<0.05). 【Conclusion】 The prevalence of emotional and behavioral abnormalities is high in children with OAB, which is related to female gender, high BMI, puberty, constipation, enuresis and severity of OAB.

Objective: To investigate the influencing factors of overactive bladder (OAB) in college freshmen and the impacts of OAB on their mental health, quality of life and social interaction. Methods: An epidemiological questionnaire survey was conducted in an anonymous manner on the prevalence of OAB among 5300 freshmen aged 17 to 22 years enrolled in the 2023—2024 academic year in Xinxiang Medical University and Sanquan College of Xinxiang Medical University.The questionnaire included questions on basic information, history of urinary tract infection, constipation, smoking, history of alcohol consumption, history of coffee/strong tea drinking, history of carbonated beverage drinking, redundant prepuce, phimosis, holding urine, chronic insomnia, self-rating anxiety scale (SAS), quality of life score (QoL), and social avoidance and distress scale (SADS).The influencing factors of OAB were analyzed with multivariate logistic regression analysis.The subjects were grouped according to whether they had OAB, and the differences in SAS, QoL and SADS between the OAB group and non-OAB group were compared.The impacts of OAB on the anxiety level, quality of life, and social interaction were analyzed with multiple linear regression analysis. Results: The overall prevalence rate of OAB was 4.9% (244/5018).Multivariate logistic regression analysis showed that the history of urinary tract infection (OR=0.177), constipation (OR=0.636), smoking (OR=0.582), alcohol consumption (OR=0.685), coffee/strong tea drinking (OR=0.387), carbonated beverage drinking (OR=0.631), redundant prepuce (OR=0.673), phimosis (OR=0.311), urine holding (OR=0.593), and chronic insomnia (OR=0.256) were influencing factors for the occurrence of OAB (P＜0.05).The OAB group had higher SAS score [(41.18±6.54) vs. (38.61±6.36)], QoL score [(3.65±1.20) vs. (2.79±0.95)], social avoidance score [(6.25±1.86) vs. (5.86±1.51)], social distress score [(6.27±1.59) vs. (5.97±1.32)], and total SADS score [(12.51±2.35) vs. (11.84±2.01)] than the non-OAB group (P＜0.05).The results of multiple linear regression analysis showed that OAB could independently affect the scores of QoL, SAS, and SADS.The OAB group had higher scores of QoL, SAS, and SADS compared with the non-OAB group (P＜0.001). Conclusion: History of urinary tract infection, constipation, smoking, alcohol consumption, coffee/strong tea drinking, carbonated beverage drinking, redundant prepuce, phimosis, urine holding, and chronic insomnia are influencing factors for the occurrence of OAB in male college students.Moreover, OAB has negative impacts on their mental health, quality of life, and social interaction.
