ABSTRACT

Objective:To retrospectively analyze the urodynamics quality in Southwest China, and find out the main issues of urodynamics quality in Southwest China and try to find out the improvement ways.Methods:In this study, a two-stage sampling method was used.In the first stage, 10 medical institutions in Southwest China were selected by cluster sampling from March to June, 2020.In the second stage, according to the development of UDS in Southwest China, the sample size estimation formula was adopted, and the loss of follow-up rate in reports extraction was considered, the initial sample size was 350. As the workload of UDS in the 10 medical institutions involved in the study was equivalent, 35 urodynamics traces from each medical institution were selected. The initial samples should also meet the inclusion criteria: ①patients with clear medical history and complete clinical data; ②UDS traces were clear; ③UDS system was water filled system; ④age>18, and 150 urodynamic traces were included in the final study. We evaluated the quality of enrolled urodynamics traces, and the quality evaluation standard according to the guidelines established by the International Continence Society (ICS). The evaluation conducted by two independent urologist with more than 10 years working experience. Artifacts were divided into non-technical artifacts: abnormal abdominal pressure changes, urine volume <150 ml when did the uroflow test, and technical artifacts: non-standard zero setting, fail to record all urodynamics parameters, baseline drift, catheter displacement, misjudgment of detrusor physiological contraction and detrusor overactive in voiding phase, misjudgment between detrusor overactive and bladder low compliance in filling phase.Results:non-technical artifacts: 32 cases were found abnormal abdominal pressure changes (21.3%), 21 cases (14.0%) were found when did the uroflow test the urine volume <150 ml, and technical artifacts: Non-standard zero setting in 28 cases (18.7%), fail to record all urodynamics parameters in 8 cases, baseline drift in 16 cases, catheter displacement in 9 cases and misjudgment of detrusor physiological contraction and detrusor overactive in voiding phase in 12 cases, misjudgment between detrusor overactive and bladder low compliance in filling phase in 24 cases (16.0%).Conclusions:At present, the urodynamics quality in Southwest China need to be improved. The main issues were that the operator didn’t obey the basic operation and quality control process, and the operator did not have enough basic knowledge of urodynamics. It can be improved by strictly carry out the operation standard of UDS, identifying and correcting artifacts in time, and promoting the standardized urodynamic training courses.

ABSTRACT

Objective:To investigate the safety and efficacy of sacral neuromodulation(SNM)therapy for the treatment of lower urinary tract dysfunction(LUTD)in elderly patients.Methods:Clinical data of 91 elderly patients with LUTD from multiple medical institutions who received SNM during the period from January 2012 to December 2016 were retrospectively analyzed.Patients were divided into four groups: the interstitial cystitis(IC)group(n=28), the neurogenic bladder(NB)group(n=36), the overactive bladder syndrome(OAB)group(n=13)and the idiopathic dysuria(ID)group(n=14). Different sets of evaluation parameters were used for different diseases.Patients’ baseline data and data in stage I(test phase)and stage Ⅱ(permanent SNM)were recorded, statistically analyzed and compared.Results:Ninety-one people underwent SNM treatment.Of them, 53 patients received permanent implants(stage Ⅱ), and the total conversion rate of stage I to stage Ⅱ was 58.2%(53/91). Patients receiving permanent implants(stage Ⅱ)had a preoperative period ranging from 3 months to 30 years, and were followed up for 2 to 58 months after treatment, with an average follow-up of 19.6 months.The improvement rates in stage I for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 35.4%, 31.6%, 33.7%, 32.6%, 49.2%, 43.2% and 13.2%, respectively.The improvement rates in stage Ⅱ for urinary urgency, daily urination frequency, daily nocturnal urination frequency, maximum urine volume, daily average urine volume, daily urine leakage frequency, and quality of life score were 43.2%, 40.0%, 37.8%, 50.5%, 70.5%, 70.4% and 43.2%, respectively.Three adverse events occurred, including 1 case of recurrent symptoms, 1 case of moderate infection, and 1 case of electrical lead dislocation.Conclusions:Sacral nerve stimulation has definitive and consistent curative effects on LUTD in elderly people.The follow-up time should be extended to further study the safety of sacral nerve stimulation.

ABSTRACT

Objective To assess the outcome of vesicoureteral reflux after augmentation cystoplasty in patients with neurogenic bladder.Methods Between January 2008 and January 2014,a total of 25 patients,with a hypocompliant bladder associated with vesicoureteral reflux confirmed by video-urodynamics preoperatively,were recruited in this study.They all had undergone bladder augmentation with a generous detubularized segment of bowel at our institution.No effort had been made to correct existing reflux.Preoperatively assessment included urinalysis,kidney function tests,ultrasonography,video-urodynamic evaluation.All patients had various degrees of vesicoureteral reflux.The status of vesicoureteral reflux and bladder function were studied by video-urodynamic.Results Mean follow-up was 2.2 years (range 0.5 to 5.5 years).The video-urodynamics manifested a significant improvement of bladder capacity,diminution of intravesical pressure and resolution of reflux after bladder augmentation.Of the 25 patients,20 (80%) no longer had reflux,3 (12%) had improvement,2 (8%) had no change.Sixteen of 18 with grades Ⅰ to Ⅲ (89%),all refluxing units with grade Ⅳ to grade Ⅴ (100%) showed complete cessation of reflux.Symptomatic urinary infection was not found after surgery.Conclusions Augmentation enterocystoplasty without ureteral reimplantation is effective and adequate for patients with high pressure and hypocompliant neurogenic bladder.Therefore,ureteral reimplantation is not necessary underwent when augmentation enterocystoplasty is recommended to patients with neurogenic bladder and vesicoureteral reflux.

ABSTRACT

Objective To investigate the effects of amplitude dependent morphological and proliferative changes in human bladder smooth muscle cells (hBSMCs) undergoing physiological stretch in vitro.Methods The hBSMCs were cuhured on silicone membrane and stretched similarly to a bladder cycle at range of stretches and time.The elongation would increase up to 2.5% every 3 h and 5% (or 10%,15%,20% and 25% depending on the experiment design) in the next 1 h,followed by a rapid decrease,cyclically maintained for a total of 16 h.In subsequent 8 h (24 h cycles) the membrane was maintained in relaxed position.Immunofluorescence and confocal laser scanning microscope were employed to assess the morphological changes.Cell counting kit-8 (CCK-8) and flow cytometry were used to assess the cell proliferation.Results The hBSMCs showed contractile phenotype after application of mechanical strain.Compared with control,the strains at 5%,10%,15%,20% and 25% induced most of the cells to change from a more spread-out and stellate state with large cell surface contact areas to a typical spindle-like morphology.The orientation angle of BSMCs remarkably differed depending on the applied strain's magnitude.Absorbance value,which reflects the proliferation activity,analyzed by CCK-8 was improved from 0.471 ± 0.027 (control) to 1.320 ± 0.094 (5% elongation group,P < 0.0001),1.001 ± 0.029 (10% elongation group,P <0.0001),0.821 ±0.032 (15% elongation group,P<0.0001),0.621 ±0.032 (20% elongation group,P =0.0004) and 0.591 ± 0.056 (25% elongation group,P =0.0268),respectively.Cell proliferation index increased from (29.35 ±0.55)% (control) to (55.55 ± 1.05)% (5% elongation group,P <0.0001),(47.70 ±0.20)% (10% elongation group,P<0.0001),(35.40 ±2.10)% (15% elongation group,P <0.0001),respectively.However,no significant difference was found in either 20% elongation group (34.85 ±0.55)% (P=0.1372) or 25% elongation group (30.35 ±0.45)% (P=0.5234).Conclusions Proliferative and morphological changes could be observed in hBSMCs in vitro.Maximal proliferative potential could be seen at 5% of stretch.

ABSTRACT

Objective To evaluate the effectiveness and indications of a new minimally invasive surgical procedure,the tension-free vaginal tape-SECUR (TVT-S),in the treatment of female stress urinary incontinence (SUI). Methods Twenty-seven consecutive women with stress urinary incontinence underwent the procedure under local anesthesia.The mean age of the study group was 51 (range 25-69)years,average disease duration was 7 (1-20) years.In one case,repair of pelvic floor defects had been made previously.According to the pelvic organ prolapse quantitive(POP-Q) (American College of Obstetrics and Gynecology),the Aa>-1 cm.Swab tests have shown that the angle of urethra Was greater than 60 degrees,while the evaluation of clinical symptoms were grade Ⅱ.The urodynamie test preoperatively of 27 cases display that bladder compliance was normal,mean maximum urethral closure pressure was 40cm H2O(25-60 cm H2O),and VLPP was greater than 60 cm H2O.Minimum follow up was three months (range 3-15 months).The pre-operative maximal urethral cloSHre pressure (MUCP) of all patients was above 30 cm H2O.Ninety-six percent of patients had pure USI,one patient had mixed urodynamic incontinence (MUI).Collection of the data included operative time a well as pre-and post-operative complications.Patients were post-operatively assessed by a validated urinary incontinence-specific measure of Quality of Life (QoL) questionnaire which was completed by all patients at least three months after surgery. Results All patients who underwent the procedure were under local anesthesia.Of these patients,4 cases (MUCP<30 cm H2O) underwent TVT-S with U position while the other 23 underwent TVT-S with Hammock position.The mean operation time was 8 minutes (range 6-15 min) and blood loss during operation was about 10 ml.There were no urethral and bladder injuries during the procedure.Postoperative indwelling duration was 0-1 day.After follow-up,26 patients were cured without pad usage and 1 with mixed UI had prominent improvement in urgency incontinence symptoms.The quality of life was also improved significantly.93 % patients were satisfied with the postoperative improvement in urinary incontinence symptoms,and the more severe preoperative symptoms the higher satisfaction rate postoperatively. Conclusions TVT-S iS a safe,effective and minimally invasive procedure for SUI with less complication.The patients with normal bladder compliance and MUCP,urethral hypermobility are indicated for this surgery,some elderly patients or patients with low urethral pressure were proposed to undergo U position TVT-S or TVT.
