RESUMO

PURPOSE: Neurogenic bladder associated with spina bifida disease remains a major cause for mortality or morbidity due to kidney damages. However, we currently do not know which urodynamic findings are associated with an higher risk of upper tract damages in spina bifida patients. The objective of the present study was to evaluate urodynamic findings associated with functional kidney failure and/or with morphological kidney damages. METHODS: A large single-center restrospective study was conducted in our national referral center for spina bifida patients using our patients' files. All urodynamics curves were assessed by the same examinator. Functional and/or morphological evaluation of the upper urinary tract were done at the same moment as the urodynamic exam (between 1 week before and 1 month after). Kidney function was assessed using creatinine serum levels or 24 h urinary creatinine levels (creatinine clearance) for walking patients, or with the 24 h urinary creatinine level for wheelchair-users. RESULTS: We included 262 spina bifida patients in this study. Fifty-five patients had a poor bladder compliance (21.4%) and 88 of them had detrusor overactivity (33.6%). Twenty patients had a stage 2 kidney failure (eGFR < 60 ml/min) and 81 patients out of 254 (30.9%) had an abnormal morphological examination. There were three urodynamic findings significantly associated with UUTD: bladder compliance (OR = 0.18; p = 0.007), Pdetmax (OR = 14.7; p = 0.003) and detrusor overactivity (OR = 1.84; p = 0.03). CONCLUSION: In this large series of spina bifida patients, maximum detrusor pressure and bladder compliance are the main urodynamic findings determinants of UUTD risk.

RESUMO

OBJECTIVE: Neurogenic bladders can suffer from overactivity, underactivity or dyssynergia depending on the level of the initial lesion. These symptoms can lead to severe alterations of the upper urinary tract. One of the first-line treatments is the transcutaneous tibial posterior stimulation (TTNS), which was demonstrated to be efficient on urodynamics. But it is an invasive, expensive and sometimes not patient-accepted examination, contrary to the uroflowmetry. The aim of this study is to assess the feasibility of a follow-up with a uroflowmetry when treated by TTNS and show that the maximum flow rate increased after treatment, displaying a better detrusor contraction. METHODS: In total, 38 patients with neurogenic bladder undergoing a 12-weeks TTNS treatment and with 2 uroflowmetries interpretable before and after treatment were included. The maximum flow rate (Qmax), the urinated volume and the post-void residual (PVR) were retrieved from the uroflowmetry, and the USP-score and the urinary discomfort were asked at each appointment. RESULTS: Qmax is increased from 17,53ml/s to 18,26ml/s, as well as the PVR (from 76,97ml to 79,16ml). Urinated volume is decreased from 241,4ml to 193,66ml. Patients feel enhanced after TTNS according to the decrease in the USP-score and the urinary discomfort scale. CONCLUSION: The increase of the cystomanometric capacity and the delay of the detrusor overactivity due to TTNS explains the reduction of the urinated volume and the increase of PVR. Increased Qmax might show a better voluntary bladder contraction, with a restraint due to the lack of abdominal pressure measurement during voiding.

RESUMO

AIM: The objective of the present study was to compare the outcomes of open versus laparoscopic versus robotic cystectomy and ileal conduit for neurogenic lower urinary tract dysfunction (NLUTD). METHODS: The charts of all patients who underwent cystectomy and ileal conduit for NLUTD between January 2004 and November 2020 in an academic center were retrospectively reviewed. The approach was either open, laparoscopic or robot-assisted depending on the period (i.e., three consecutive era). For the robotic approach, the diversion was done either intracorporeally or extracorporeally. We compared the perioperative and late postoperative outcomes between the three groups. RESULTS: After exclusion of 10 patients with non-neurogenic benign conditions, 126 patients were included over the study period. The most frequent neurological conditions were multiple sclerosis (36.5%) and spinal cord injury (25.4%). The approach was open, laparoscopic or robot-assisted in 31 (24.6%), 26 (20.6%) and 69 (54.7%) cases respectively. Seventy-two patients experienced a 90-day postoperative complication (57.1%) of which 22 had a major complication (Clavien 3 or higher, 17.5%) including one death (0.8%). The rate of major postoperative complications was significantly lower in the robotic group (23% vs. 23% vs. 10%; p = 0.049) while the rate of overall complications was comparable across the three groups (58.1% vs. 53.9% vs. 60.6%; p = 0.84). After a median follow-up of 23 months, 22 patients presented a late complication (17.6%), mainly incisional hernia (5; 4%) and uretero-ileal stricture (9; 7.2%). The rate of late complications did not differ significantly between the three approaches. CONCLUSION: Cystectomy and ileal conduit for neurogenic bladder is associated with a relatively high perioperative morbidity. The robot-assisted approach may decrease the risk of major postoperative complications.

RESUMO

AIMS: To report the long-term functional outcomes of artificial urinary sphincter (AUS) implantation in female patients with spinal dysraphism and stress urinary incontinence (SUI) related to intrinsic sphincter deficiency (ISD). METHODS: The charts of all spina bifida female patients with SUI due to ISD who underwent AUS (AMS 800) implantation between 2005 and 2019 at three academic departments of urology were retrospectively reviewed. Reoperation was defined as either revision or explantation of the AUS device. Reoperation-free survival of the AUS device was estimated using the Kaplan-Meier method. Continence status as per patients' subjective assessment was categorized as follows: complete continence (no pads), improved continence, unchanged SUI or worsened SUI. RESULTS: Twenty-three patients were included, 69.6% were self-catheterizing. The median follow-up was 14 years. Median time to first reoperation was 10 years. Survival rates without reoperation were 85.9%, 41.8%, 34.6%, and 20.9% at 5, 10, 15, 20 years, respectively. Survival rates without AUS explantation were 90.7%, 66.3%, 55.2%, and 41.4% at 5, 10, 15, 20 years, respectively. None of the patients who underwent device explantation had a new AUS implanted. The only predictive factor of reoperation-free survival was the type of spinal dysraphism (hazards ratio = 3.60 for closed vs. open dysraphism; p = .04). At last follow-up, 17 of the 23 patients were fully continent (73.9%). CONCLUSION: AUS in female patients with spina bifida may be associated with satisfactory long-term functional outcomes and a high reoperation rate. The median time to first reoperation was similar to what is reported in the male AUS literature (10 years).

RESUMO

PURPOSE: To evaluate the determinants and prognostic value of post-operative maximum urethral closure pressure (MUCP) after AUS implantation in male patients. METHODS: The charts of all male patients who had an AUS implantation between 2008 and 2018 at a single center were reviewed retrospectively for an exploratory study. A post-operative urethral profilometry was performed systematically as part of routine daily practice over the study period to assess the post-operative MUCP with the AUS consecutively closed (c-MUCP) and opened (o-MUCP). The difference between c-MUCP and the manufacturer's theoretical pressure objective determined by the pressure regulating balloon (PRB) was calculated (diff-th-MUCP). The primary endpoint was social continence at 3 months defined as 0-1 protection/day. RESULTS: Ninety patients were included. The median age was 71 years, and the median follow-up was 50 months. The etiology of incontinence was radical prostatectomy in 84% of cases, and endoscopic prostate surgery in 6.6% of patients. There were 74.4% of patients who were socially continent at 3 months. The c-MCUP was significantly higher in the continent group (53 [42.2, 60.2] vs 62 [58, 70] p = 0.02). The diff-th-MUCP did not differ significantly between the two groups (18 [0, 23] vs 1 [- 2, 7.7] p = 0.29). The c-MUCP was not statistically associated with the risk of revision and/or explantation. CONCLUSION: The MUCP after AUS implantation in male patients often differs from the manufacturer's pressure objective. The postoperative c-MUCP might be significantly associated with functional outcomes suggesting that it might be a valuable tool for treatment decision-making. This should be confirmed by larger studies.

RESUMO

OBJECTIVES: The aim of this study was to investigate the disease-specific urinary levels variations of neurotrophins (NGF, BDNF), mediators of inflammation (TGFß-1, PGE-2) and markers of extracellular matrix alterations (TIMP-2) in patients with multiple sclerosis (MS) spinal cord injury (SCI), or spina bifida (SB), and neurogenic detrusor overactivity (NDO). METHODS: A prospective single-center study was conducted between March 2015 and March 2017. Patients aged over 18 years old, with neurological disease, with a urodynamic diagnosis of NDO were included. The urinary levels of NGF, BDNF, TIMP-2, PGE 2, and TGF-ß1 were measured using dedicated ELISA kits. RESULTS: Forty-one patients were included: 6 with MS, 20 with SCI, and 15 with spina bifida. The average urinary level of NGF/Cr was significantly higher in MS patients compared to other neurologic populations (8 vs. 0.56 vs. 1.25 pg/mg of creatinine; p = 0.001) as well for the average urinary level of BDNF (88.3 vs. 5 vs. 4.8 pg/mg of creatinine; p < 0.0001). SCI patients had a significantly lower level of TGFß-1 than SB patients (p = 0.04). The urinary level of PGE2 was significantly correlated with the Body Mass Index (r = 0.61; p = 0.0002). CONCLUSION: All NDO may not be created equal from the molecular standpoint. Multiple sclerosis patients had higher urinary levels of neurotrophins than in other neurologic populations with NDO. Urinary TGFß-1, a strong determinant of extracellular matrix, was significantly higher in spina bifida patients compared to SCI patients. These findings underscore the importance of using and interpreting those possible urinary markers in a disease-specific fashion.

RESUMO

AIMS: Radical prostatectomy may cause stress urinary incontinence (SUI). We compared continent and incontinent men after radical prostatectomy, in regard to the change of the temporal pattern of pelvic floor activation during cough. METHODS: Twenty-two patients were included in this prospective, multicentric study. All patients gave their informed consent. Simultaneous recordings of electromyographic activity of external anal sphincter (EAS EMG) and external intercostal muscle (EIC EMG) during cough were performed with a pair of pregelled surface electrodes. Cough effort caused an involuntary pelvic contraction. Intercostal muscles recording was chosen because they are one of the muscular components of cough initiation with diaphragm muscle. Twenty-four-hour pad-weighing test was used to quantify urinary incontinence. The primary endpoint was the latency between the onset of EIC EMG and EAS EMG (RT3), during a cough effort. We also measured the contraction time, the maximum EAS EMG activity, and the area under the curve. RESULTS: All the patients were analyzed: 12 continent and 10 with SUI. The median age was 66 years old. Both groups were similar except in term of follow-up. Median latency was increased by -1.7 ms (-47.9; +34.2) to 55.8 ms (+47.5; +80) in patients with SUI (P = 0.0033; Table 2). The duration of the contraction, the maximum EAS EMG activity and the area under the curve were not different. CONCLUSIONS: The latency between the onset of EIC EMG and EAS EMG is increased in patients with SUI after radical prostatectomy. It may be one of the reasons for SUI in these patients.

RESUMO

PURPOSE: We aimed to review the current knowledge on the epidemiology, diagnosis, and management of urinary and sexual dysfunction in patients with TTR amyloidosis (ATTR). METHODS: We performed a review of the literature, screening for randomized controlled trials, prospective and retrospective series, position papers, and guidelines on urinary and sexual dysfunction in ATTR patients published in PubMed and Embase. RESULTS: Lower urinary tract dysfunction is present in up to 83% of patients with ATTR. Voiding symptoms are the most common, reported in 34.8-87.5% of patients, while urinary tract infections are reported in up to 50%. Urinary incontinence is observed in 16.7-37.5% of the ATTR population, mostly due to decreased urethral resistance. Sexual dysfunction affects over 40% of ATTR patients, with erectile dysfunction and sexual arousal disorder being the most common symptoms in male and female patients, respectively. In addition to a thorough clinical examination, invasive pressure-flow urodynamic testing is a cornerstone in the assessment of ATTR lower urinary tract dysfunction. The most common finding is detrusor underactivity and intrinsic sphincter deficiency. Poor bladder compliance can also be observed in patients, due to amyloid deposits on the bladder wall. Urinary tract imaging may be of interest to rule out upper urinary tract deterioration. Given the paucity of data in the ATTR population, treatment should be tailored to the individual patient. CONCLUSION: Urinary and sexual dysfunction are highly prevalent in ATTR patients. Comprehensive assessment and multidisciplinary management are keys to avoiding upper urinary tract damage and improving patients' quality of life.

RESUMO

OBJECTIVE: To assess and analyze the contemporary causes of in-hospital deaths of spina bifida patients. METHODS: It was a cross-sectional observational study of the longitudinal national cohort of all patients hospitalized in French public and private hospitals. We analyzed the data from the French hospital discharge database (Programme de Médicalisation des Systemes d'Information, PMSI) from 2009 to 2014. The number of in-hospital deaths was extracted using the combination of the ICD-10 codes "Q05" or "Q760" and a discharge code = 9. RESULTS: There were 138 in-hospital deaths of spina bifida patients over the 6-year study period. The median age at death was 41 years (IQR: 25-52). The median age at death was significantly lower in patients with vs without hydrocephalus (26.6 vs 45.5 years; P <.0001). The leading cause of in-hospital death was urologic disorders (n = 24; 17.3%). Other main causes of death were pulmonary disorders (n = 23; 16.7%), neurologic disorders (n = 19; 13.8%), and bowel disorders (n = 15; 10.9%). Upper urinary tract damage accounted for most of the urologic causes of death: 8 patients died from urinary tract infections (33.3%), 7 patients died from renal failure (29.2%), 4 died from bladder cancer (16.7%), and 5 from other urologic causes. The only variable significantly associated with a death from urologic causes was the absence of hydrocephalus (OR = 0.26; P = .009). CONCLUSION: Urologic disorders remain the leading cause of in-hospital death in spina bifida patients in France. The present study highlights that efforts to improve the urologic management of the spina bifida population are still greatly needed.
