ABSTRACT

Diabetic bladder dysfunction is one of the most common complications of urinary tract in diabetes. It is believed that the disorders of glucose metabolism, local tissue ischemia, superoxide-induced free radical production and axonal transport disorder are all involved in the development of diabetic bladder nerve dysfunction. Oxidative stress is believed to be the core mechanism of the above mentioned etiology. It may affect the transcription and translation process in the nucleus by interfering with the balance of intracellular oxidation and antioxidant, metabolism of neurotrophic factors and cellular signal transduction pathways, resulting in dysfunction of several important cellular pathways and decreased membrane stability. And eventually lead to nerve cell apoptosis. Therefore, controlling blood glucose, improving the microenvironment around dorsal root neurons, and protecting the stability of mitochondrial membrane may be potential methods for the treatment of diabetic bladder nerve dysfunction.

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

The clinical and urodynamic data of 37 patients with benign prostate hyperplasia (BPH) and 30 diabetic patients complicated with BPH (BPH+DM) admitted between Jan 2014 and July 2017 were analyzed retrospectively. The International Prostate Symptom Score (IPSS), maximal flow rate (Qmax), post-voiding residual urine volume (PVR), maximum cystometric capacity (MCC), first desire to void (FDV), pressure of detrusor maximum (Pdet, max), bladder outlet obstruction index (BOOI), bladder contraction index (BCI) were compared between BPH group and BPH+DM group. According to BOOI-BCI linear regression, 22 cases (group A) and 15 cases (group B) of BPH patients were above and below the linear curve; while there were 14 cases (group C) and 16 cases(group D)of BPH+DM patients above and below the curve, respectively. The mean±SD FDV, MCC, Pdet, max, PVR, BOOI, BCI were (172.7±93.0)ml vs. (300.5±118.4)ml (P<0.05), (311.9±147.1)ml vs. (509.3±98.6)ml (P<0.05), (84.7±51.5)cmH2O(1 cm H2O=0.098 kPa) vs. (49.7± 32.9)cmH2O vs (P<0.05), 10.0 ml(0—200 ml) vs. 41.5 ml(0—450 ml), 69.7 ± 53.7 vs. 35.9 ± 32.3 (P<0.05), 122.3±50.2 vs 84.2±43.3 (P<0.05) in BPH and BPH+DM groups, respectively. In BPH group and BPH+DM group, the regression coefficients of BOOI-BCI were 0.889 and 0.724, respectively. In group A and group B, the difference value of IPSS and Qmax pre and post operation were 7.6±3.5 and 7.3±4.1 (P>0.05), (2.6±1.1)ml/s and (3.7±1.3) ml/s (P<0.05), respectively. In group C and group D, the difference value of IPSS and Qmax pre and post operation were 5.3 ± 2.4 and 6.0 ± 3.3 (P>0.05), (2.4 ± 1.0)ml/s and (3.8 ± 1.4)ml/s (P<0.05), respectively. The study indicates that the therapeutic effect is better for the patients blow BOOI-BCI regression linear curve compared to the patients above the linear curve.

ABSTRACT

Interstitial cystitis/bladder pain syndrome is a chronic pain syndrome characterised by pain/ discomfort attributed to the bladder,with associated urgency and urinary frequency.Its etiology is unknown and the syndrome probably have different manifestations.There is no specific treatment and multi-treatment often been used to treat interstitial cystitis/bladder pain syndrone.Bladder instillation therapy is often used as an important treatment because the drug is concentrated in the bladder and keeps a higher concentration.But the drug selection and treatment regimen of bladder instillation are not uniform.A number of intravesical agents are reviewed in this paper along with the available evidence for their use.

ABSTRACT

Objective Little is known about the effects of antioxidant on the micturition function in diabetic cystopathy .In this study, we investigated the effects of antioxidant sulforaphane on bladder micturition function in diabetes mellitus ( DM)mice with bladder underactivity . Met hods We established DM models in mice by intraperitoneal injection of a single dose of streptozotocin (STZ)at 65 mg/kg and randomly divided them into three groups , sulforaphane treatment (n=10), vehicle treatment (n=10), and DM model (n=10), with another 10 normal healthy mice included as blank controls.At 24 weeks of the experiment, we obtained and analyzed such indexes of mice as the body weight , fasting blood glucose (FBG), 24-hour urine volume (24 h UV) and bladder wet weight ( BWW ) , results of cystometrography , and cystometric parameters including intercontraction interval ( ICI ) , maximum bladder pressure during micturition ( Pmax ) , maximum cystometric capacity (MCC), void volume (VV), post-void residual urine vol-ume (PVR) and residual urine rate (RUR). Results Compared with the blank controls , the DM models with bladder underactivity showed significantly increases in BWW ([67.96 ±2.35]mg), 24 h HU ([22.47 ±1.93]mL), MCC ([0.70 ±0.03]mL), VV (0[.23 ±0.01]mL), PVR ([0.49 ±0.02]mL), RUR ([70.10 ± 0.80]%), and ICI, but a remarkable decrease in Pmax .Sulforaphane treatment significantly reduced BWW ([576.9 ±2.41]mg), 24 h HU ([16.27 ±1.51] mL), MCC ([0.54 ±0.03]mL), PVR ([0.34 ±0.02]mL), RUR ([62.71 ±1.26]%), and ICI of the diabetic mice . Conclusion Sulforaphane could improve bladder micturition function in mice with STZ-induced DM , which might be related to its action mechanism of antioxidative stress damage .

ABSTRACT

BACKGROUND:The patients with neurogenic urinary incontinence could be cured to restore their urinary storage function through the implant of the suburethral sling made of appropriate materials in a reasonable way. Meanwhile the choice of materials and the safe and effective control of tension are crucial factors. OBJECTIVE:To review the implanted methods, effectiveness and safety of sling made of different materials in the surgical treatment of neurogenic stress urinary incontinence. METHODS:The PubMed database, English database, CNKI database and related English books were retrieved with computer from January 1986 to January 2012 for the articles on the urethral sling material, urethral sling placement methods, efficacy and safety. The key words were“urethral sling, neurogenic, urinary incontinence”in English and Chinese. Final y, 47 articles were included for review according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:Urethral sling is a safe, handy, and micro-invasive operation, by using autologous fascia or various synthetic materials to implant into the body. The mechanism of neurogenic urinary incontinence is mainly related with the change of bladder function or the insufficiency of urethral sphincter function. However, it is stil a big problem for us to assure the postoperative ability of such patients to store and control urine because of their complicated conditions.
