RESUMEN
【Objective】 To analyze the results, characteristics and clinical value of video urodynamic study (VUD) of lower urinary tract symptoms (LUTS) in young male. 【Methods】 A total of 106 young male LUTS patients (18-45 years old) who received VUD in our hospital during Jan.2016 and Sep.2021 were collected to analyze the clinical and imaging urodynamic characteristics. 【Results】 Of the 106 patients, 55 (52.44%) had neurogenic lower urinary tract dysfunction (NLUTD)with clear neurological etiology, and 51 (48%) had non-neurogenic lower urinary tract dysfunction (NNLUTD). In NLUTD patients, dysuria was the most common symptom (76.74%); lumbosacral lesions were the main cause (76.36%); imaging urodynamics indicated weakening of detrusor muscle in different degrees. In NNLUTD patients,the main symptoms were frequent urination (48.72%) and dysuria (48.72%); about 58.97% of patients had two or more LUTS, and the main diagnosis was detrusor underactivity (DU)(35.90%). 【Conclusion】 NLUTD in young male is characterized by varying degrees of detrusor muscle weakness, detrusor sphincter dyscoordination, and decreased bladder compliance. NNLUTD is mostly caused by detrusor overactivity (DO) and DU.
RESUMEN
Objective:To explore the efficacy and safety of robot assisted laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse.Methods:The data of 16 patients who underwent robot assisted laparoscopic sacrocolpopexy in Beijing Hospital from September 2019 to May 2022 were collected. The average age was (73.5±9.3) years, the preoperative course was 4-240 months, the body mass index was (24.2±1.7) kg/m 2, the number of births was (1.7±0.8), and the quantitative index of pelvic organ prolapse (POP-Q) was grade Ⅲ -Ⅳ. The maximum urine flow rate before operation was (9.6±3.4) ml/s, the maximum detrusor pressure during urination was 26 (20, 32) cmH 2O, the first sense urine volume of the bladder was (119.1±39.4) ml, the first sense urine urgency volume of the bladder was (253.6±75.7) ml, the maximum bladder pressure capacity was (406.0±79.8) ml, and the residual urine volume was 10 (10, 28) ml. The preoperative PFDI-20 score was 100 (70, 122) and the PFIQ-7 score was 107 (90, 160). During the robot assisted laparoscopic sacrocolpopexy, the right area of the sacral promontory was exposed, the anterior and posterior walls of the uterus were separated, and the 2 cm small hole was separated from the right broad ligament of the uterus. The mesh was cut into a "Y" shape and passed through the small hole. The anterior and posterior leaves of the Y-shaped mesh were sutured to fix the cervix, and the other end was fixed to the anterior longitudinal ligament of the sacrum. The operation time and intraoperative bleeding were observed. The effect of surgery was evaluated by preoperative and postoperative urodynamic imaging, POP-Q stage, PFDI-20 score and PFIQ -7 score. Results:All the 16 operations were successfully completed. No injury of urethra, bladder, rectum, important blood vessels and nerves occurred during the operation. The average operation time was (255.6±56.0) min, and the average amount of bleeding was (28.8±18.2) ml. There was no inhibitory contraction wave in 7 patients (44%) before operation, suggesting that there was detrusor overactivity. After operation, the detrusor overactivity disappeared or significantly decreased in 7 patients. The postoperative follow-up period was 3-36 months. During the follow-up period, one patient had recurrence, and the rest had no prolapse and urination problems. The POP-Q stage was reduced to grade 0-Ⅰ after the operation. The subjective satisfaction rate of patients was 94%. The PFDI-20 score [13(8, 24)] and PFIQ -7 score [11(6, 15)] after operation were significantly reduced ( P<0.001), the initial urgent volume of bladder (272.5±88.5) ml was significantly increased compared with that before operation ( P=0.038), and the maximum volume of bladder (427.2±79.2) ml was significantly increased compared with that before operation ( P=0.006). Image urodynamics showed that the patient basically recovered the pelvic floor anatomy and achieved functional reduction. Conclusions:Robot assisted laparoscopic sacrocolpopexy has good subjective and objective effects in POP, low recurrence rate and less complications. It needs a larger sample size study for confirming the improvement of bladder function.
RESUMEN
Objective To explore the relationship between congenital vesical ureteral reflux(VUR) and bladder dysfunction in children through videourodynamic examination.Methods Sixty-seven children with congenital VUR in the First Affiliated Hospital of Zhengzhou University from Apr.2011 to Jul.2013 were included,and their clinical information of urnary tract infection,detrusor activity,dysfunctional voiding and grade of VUR were recorded.All the children were categorized as normal,isolated detrusor overactivity (DO)and dysfunctional voiding (DV) (with or without DO) according to the manifestation of urodynamic patterns,who were also divided into groups of low grade (Ⅰ-Ⅱ) VUR or high grade (Ⅲ-Ⅴ) VUR.Data of video-urodynamic examination,urinalysis,and voiding cystourethrogram were collected to investigate the relationship between bladder dysfunction,sides and grade of VUR and urinary tract infection.Results Totally 73.1％ (49/67 cases) of children with VUR were found having bladder dysfunction,which consisted of 49.3％ (33/49 cases) of DO,23.8％ (16/49 cases) of DV.Children with isolated DO tended to manifest unilateral,low grade reflux (grade Ⅰ-Ⅱ) with less urinary infection.However,children with DV,isolated or combined with DO manifest bilateral,high grade reflux(grade Ⅲ-Ⅳ),and often with urinary infection.Conclusions Video urodynamic study is useful for evaluation of bladder function in children with VUR,which is important in management of VUR.
RESUMEN
PURPOSE: Voiding dysfunction is known to affect on the result of treatment for vesicoureteral reflux(VUR) in children. The aim of this study is to find out specific urodynamic abnormality in the children with VUR and voiding dysfunction. MATERIALS AND METHODS: We evaluated 16 children having VUR with voiding dysfunction symptoms. Voiding symptoms were frequency, urgency, urge incontinence, nocturnal enuresis and voiding postponement. An awake video-urodynamic study(video-UDS) was performed without anesthesia. RESULTS: Urodynamic abnormalities were found in 11 children(69%). The most common urodynamic abnormality was uninhibited detrusor contraction(10 cases, 63%), and 8 of these patients had urgency and/or urge incontinence. Other urodynamic abnormalities were small maximum cystometric capacity(5 cases, 31%), and detrusor sphincter dyssynergia(DSD)(3 cases, 19%). All the children with DSD had voiding postponement. VUR was found in 8 children(50%) during video-UDS. Among the urodynamic parameters small cystometric bladder capacity was found to be a most significant factor in predicting low Pressure VUR(sensitivity 100%, specificity 100%, p=0.018). CONCLUSIONS: These results suggest that abnormal detrusor activity is more frequent than abnormal coordination between detrusor and external sphincter activity in the children with VUR and voiding dysfunction symptoms. And small maximum cystometric capacity seems to be a significant urodynamic parameter for perpetuating VUR in these children.
