Adjustable single-incision mini-slings (Ajust®) versus other slings in surgical management of female stress urinary incontinence: a meta-analysis of effectiveness and complications
Tập 18 - Trang 1-10 - 2018
Adjustable single-incision mini-sling (SIMS) is a new category of SIMS for stress urinary incontinence (SUI). The aim of this study was to compare the efficacy and safety of adjustable single-incision mini-sling with other slings. Literature search in databases such as Pubmed, and Conchrane Library was performed up to December, 2015. The outcomes including cure rate, operation time, postoperative pain score and complications were reanalyzed. The pooled relative risk (RR) and mean difference (MD) with their 95% confidence interval (95% CI) were calculated by RevMan v5.0. Eight studies with 1093 SUI female patients were included. There was no significant difference between adjustable SIMS and other slings (transobturator slings and MiniArc) in patients subjective cure rate and objective cure rate. In addition, adjustable SIMS was associated with a significantly shorter operative time and lower postoperative pain score when comparing adjustable SIMS with transobturator tape (MD = − 1.35; 95%CI: -2.24 to − 0.46, P = 0.003). For the complications, there was also no significant difference between adjustable SIMS and transobturator slings. Adjustable SIMS had equally efficacy for SUI compared with transobturator slings and MiniArc. However, the significantly shorter operative time and lower postoperative pain score than transobturator tape supported the clinical application of adjustable SIMS.
Development and validation of a preoperative nomogram for predicting patients with impacted ureteral stone: a retrospective analysis
Tập 21 - Trang 1-10 - 2021
To develop and validate a practical nomogram for predicting the probability of patients with impacted ureteral stone. Between June 2020 to March 2021, 214 single ureteral stones received ureteroscopy lithotripsy (URSL) were selected in development group. While 82 single ureteral stones received URSL between April 2021 to May 2021 were included in validation group. Independent factors for predicting impacted ureteral stone were screened by univariate and multivariate logistic regression analysis. The relationship between preoperative factors and stone impaction was modeled according to the regression coefficients. Discrimination and calibration were estimated by area under the receiver operating characteristic (AUROC) curve and calibration curve respectively. Clinical usefulness of the nomogram was evaluated by decision curve analysis. Age, ipsilateral stone treatment history, hydronephrosis and maximum ureteral wall thickness (UWTmax) at the portion of stone were identified as independent predictors for impacted stone. The AUROC curve of development and validation group were 0.915 and 0.882 respectively. Calibration curve of two groups showed strong concordance between the predicted and actual probabilities. Decision curve analysis showed that the predictive nomogram had a superior net benefit than UWTmax for all examined probabilities. We developed and validated an individualized model to predict impacted ureteral stone prior to surgery. Through this prediction model, urologists can select an optimal treatment method and decrease intraoperative and postoperative complications for patients with impacted ureteral calculus.
Comparison of ureteroscopy (URS) complementary treatment after extracorporeal shock wave lithotripsy failure with primary URS lithotripsy with holmium laser treatment for proximal ureteral stones larger than10mm
Tập 21 - Trang 1-7 - 2021
To compare ureteroscopy (URS) complementary treatment following extracorporeal shock wave lithotripsy (SWL) failure with primary URS lithotripsy for proximal ureteral stones > 10 mm, and try to find out acceptable number of SWL sessions followed by safe URS. This was a retrospective study following approval from Medical Ethics Committee of People's Hospital of Chongqing Banan District. Patients (n = 340) who received URS in our hospital for stones > 10 mm from Jan 2015 to June 2020 were divided into two groups according to their previous SWL history. Group 1 consisted of 160 patients that underwent unsuccessful SWL before URS. Group 2 encompassed 180 patients without SWL before URS. Patient’s operative outcomes were compared. A logistic regression and receiver operator characteristics (ROC) were used to identify the acceptable number of SWL sessions prior to URS, regarding the intra-operative complications of URS. The group 1 required more surgery time (41.38 ± 11.39 min vs. 36.43 ± 13.36 min, p = 0.01). At the same time, more intra-operative (68.1% VS 22.8%, p < 0.05) and post-operative (35% VS 18.0%, p = 0.001) complications occurred in group 1. Need more hospital stay in group 1 (2.7 ± 1.2 days vs 1.6 ± 1.1 days, p < 0.05). More patients in group 1 need further URS (16.3% VS 8.9%, p = 0.029). After second URS, the SFR of URS in two groups was insignificant differences (82.5% VS 88.9%, p > 0.05). The median (25–75%) of SWL sessions before URS was 2 (1–3) in group 1. According to the results of logistic regression analysis, patients suffered more SWL failure have an increased risk of complications during URS (OR = 1.995, 95% CI: 1.636–2.434). ROC showed that the optimal number of SWL session followed by URS were 0.5, with a sensitivity of 67.7% and specificity of 71.5%. Intra-operative complication rates of URS treatment were higher in patients who suffered > 1 SWL failure (72.6% vs 57.4%, p = 0.047). There was no acceptable number of SWL sessions that could be followed by URS with fewer intra-operative complications. Patients who underwent previous SWL were likely to suffer more intra-operative complications, the average operating time, hospitalization time, and needing further treatment, during URS treatment for proximal ureteral stones larger than 10 mm.
Is there a role for anterior zone sampling as part of saturation trans-rectal ultrasound guided prostate biopsy?
Tập 14 - Trang 1-6 - 2014
The prostatic anterior zone (AZ) is not targeted routinely by TRUS guided prostate biopsy (TRUS-Pbx). MRI is an accurate diagnostic tool for AZ tumors, but is often unavailable due to cost or system restrictions. We examined the diagnostic yield of office based AZ TRUS-Pbx. 127 men at risk for AZ tumors were studied: Patients with elevated PSA and previous extended negative TRUS-Pbx (group 1, n = 78) and actively surveyed low risk prostate cancer patients (group 2, n = 49). None of the participants had a previous AZ biopsy. Biopsy template included suspicious ultrasonic areas, 16 peripheral zone (PZ), 4 transitional zone (TZ) and 6 AZ cores. All biopsies were performed by a single urologist under local peri-prostatic anaesthetic, using the B-K Medical US System, an end-firing probe 4-12 MHZ and 18 ga/25 cm needle. All samples were reviewed by a single specialized uro-pathologist. Multivariate analysis was used to detect predictors for AZ tumors accounting for age, PSA, PSA density, prostate volume, BMI, and number of previous biopsies. Median PSA was 10.4 (group 1) and 7.3 (group 2). Age (63.9, 64.5), number of previous biopsies (1.5) and cores (17.8, 21.3) and prostate volume (56.4 cc, 51 cc) were similar for both groups. The overall diagnostic yield was 34.6% (group 1) and 85.7% (group 2). AZ cancers were detected in 21.8% (group 1) and 34.7% (group 2) but were rarely the only zone involved (1.3% and 4.1% respectively). Gleason ≥ 7 AZ cancers were often accompanied by equal grade PZ tumors. In multivariate analysis only prostate volume predicted for AZ tumors. Patients detected with AZ tumors had significantly smaller prostates (36.9 cc vs. 61.1 cc p < 0.001). Suspicious AZ ultrasonic findings were uncommon (6.3%). TRUS-Pbx AZ sampling rarely improves the diagnostic yield of extended PZ sampling in patients with elevated PSA and previous negative biopsies. In low risk prostate cancer patients who are followed by active surveillance, AZ sampling changes risk stratification in 6% but larger studies are needed to define the role of AZ sampling in this population and its correlation with prostatectomy final pathological specimens.
Epidemiology of complications of male circumcision in Ibadan, Nigeria
Tập 6 - Trang 1-3 - 2006
The number of infants managed for neonatal circumcision injuries in our unit has been on the increase over the past 16 years. In our search for the sources and reasons for these injuries, we were unable to identify any previous studies of circumcision injuries from our environment. We therefore decided to carry out this study in order to shed some light on this growing problem. The patients were made up of 370 consecutive consented children attending our infant welfare clinic for immunization over a period of 3 months. Information on their demographic data, their age at circumcision, where, why and who circumcised them was obtained from their mothers. They were clinically examined for the presence and type of complications of circumcision. Our circumcision rate was 87%. Neonatal circumcision had been performed in 270 (83.9%) of the children. Two hundred and fifty nine (80.7%) were performed in hospitals. The operation was done by nurses in 180 (55.9%), doctors in 113 (35.1%) and by the traditional circumcisionist in 29 (9%) of the children. Complications of circumcision occurred in 65 [20.2%] of the children. Of those who sustained these complications, 35 (53.8%) had redundant foreskin, 16 (24.6%) sustained excessive loss of foreskin, 11 (16.9%) had skin bridges, 2 (3.1%) sustained amputation of the glans penis and 1 (1.5%) had a buried penis. One of the two children who had amputation of the glans also had severe hemorrhage and was transfused. Even though the complications tended to be more likely with nurses than with doctors or traditional circumcisionists, this did not reach statistical significance (p = 0.051). We have a very high rate of complications of circumcision of 20.2%. We suggest that training workshops should be organized to adequately retrain all practitioners of circumcision on the safe methods available.
Transvaginal closure of urinary bladder opening and Mitrofanoff technique in a neurologically impaired female with chronic indwelling catheter: a case presentation
Tập 21 - Trang 1-5 - 2021
Chronic catheterization remains the only attractive option in specific circumstances, especially in neurologically impaired patients. Complications produced by the indwelling catheters, like patulous urethra and bladder neck destruction, usually lead to severe incontinence and significant nursing difficulties. Here, we describe a rare case, a urinary bladder opening representing massive and extensive destruction of the urethra and bladder sphincter due to an indwelling catheter. We present a 46-year-old paraplegic woman complaining of recurrent febrile urinary tract infections and severe urinary incontinence. She suffered from persistent malodorous urine and skin breakdowns from constant urine leakage. The vaginal examination revealed extensive destruction of the urethra and a 10 cm opening permitting the urinary bladder wall to prolapse into the vagina. The patient underwent a combined surgical approach; a transvaginal bladder closure with anterior colporrhaphy and a Mitrofanoff procedure to ensure a continent stoma for future clean intermittent self-catheterization (CISC). The patient is compliant with CISC and, remains continent twelve years after surgery. This case demonstrates that in the era of CISC, there are still neurologically impaired females suffering from rare but critical adverse effects of indwelling catheters. The urethra and bladder neck erosion represent a demanding treatment assignment. The Mitrofanoff procedure for continent stoma and the transvaginal closure of urinary bladder opening produced a lifesaving potential treatment.
Epidemic investigation of benign prostatic obstruction with coexisting overactive bladder in Shanghai Pudong New Area and its impact on the health-related quality of life
Tập 19 - Trang 1-8 - 2019
We aimed to investigate the prevalence, relative risk factors, and the impact on the health-related quality of life (HRQoL) of benign prostatic obstruction (BPO) with coexisting overactive bladder (OAB) in men aged over 50 and living in Shanghai Pudong New Area. Using a multi-stage sampling and descriptive epidemiological method, 1632 men were selected from among the general population. Participants completed an evaluation of lower urinary tracts symptoms (LUTS), including international prostate symptom score (IPSS) and quality of life (QoL) questionnaires. Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5) questionnaire. In addition, the Overactive Bladder Symptom Score (OABSS) and King’s health questionnaire (KHQ) were used to assess the impact of BPO with coexisting OAB on the HRQoL. Maximum flow rate (Qmax), postvoid residual urine volume (PVR) and prostate-specific antigen (PSA) were also recorded. A total of 1476 men with complete data were analyzed. The overall prevalence of BPO with coexisting OAB was 39.6%. Age and prostate volume were associated risk factors for BPO with coexisting OAB. In addition, BPO with coexisting OAB negatively impacted the HRQoL, with increased IPSS, QoL, OABSS, and KHQ scores and decreased IIEF-5 scores compared to that in patients with BPO without OAB. Qmax, PVR and serum PSA did not predict whether the patients had a combined BPO + OAB or not. The prostate volume and age were associated risk factors for BPO with coexisting OAB. BPO is a progressive disease and may be one of the risk factors for OAB.
Thermal effect of holmium laser during ureteroscopic lithotripsy Abstract
Background
Holmium laser lithotripsy is the most common technique for the management of ureteral stone. Studies founded that holmium laser firing can produce heat which will cause thermal injury towards ureter. The aim of our current study is to explore factors affecting thermal effect of holmium laser during ureteroscopic lithotripsy.
Methods
An in vitro experimental model is design to simulate the ureteroscopic lithotripsy procedure. Different laser power settings (10w (0.5JX20Hz, 1.0 JX10Hz), 20w (1.0 JX20Hz, 2.0 JX10Hz), 30w (1.5JX20Hz, 3.0 JX10Hz)) with various firing time (3 s, 5 s, 10s) and irrigation flow rates(10 ml/min, 15 ml/min, 20 ml/min and 30 ml/min) were employed in the experiment. The temperature around the laser tip was recorded by thermometer.
Results
The temperature in the “ureter” rises significantly with the increasing laser power, prolonging firing time and reducing irrigation flow. The highest regional temperature is 78.0 °C at the experimental set-up, and the lowest temperature is 23.5 °C. Higher frequency setting produces more heat at the same power. Laser power < =10w, irrigation flow> = 30 ml/min and “high-energy with low-frequency” can permit a safe working temperature.
Conclusion
We clarify that the thermal effect of holmium laser is related with both laser working parameters and irrigation flow. The proper setting is the key factor to ensure the safety during ureteroscopic holmium laser lithotripsy.

Dose escalation improves therapeutic outcome: post hoc analysis of data from a 12-week, multicentre, double-blind, parallel-group trial of trospium chloride in patients with urinary urge incontinence
Tập 10 - Trang 1-7 - 2010
Flexible dosing of anticholinergics used for overactive bladder (OAB) treatment is a useful strategy in clinical practice for achieving a maximum effective and maximum tolerated level of therapeutic benefit. In this post hoc analysis we evaluated the efficacy and tolerability of trospium chloride treatment for urinary urge incontinence (UUI) with focus on flexible dosing. The data came from a 12-week, randomised, double-blind, phase IIIb study in which 1658 patients with urinary frequency plus urge incontinence received trospium chloride 15 mg TID (n = 828) or 2.5 mg oxybutynin hydrochloride TID (n = 830). After four weeks, daily doses were doubled and not readjusted in 29.2% (242/828) of patients in the trospium group, and in 23.3% (193/830) in the oxybuytnin group, until the end of treatment. We assessed the absolute reduction in weekly UUI episodes and the change in intensity of dry mouth, recorded in patients' micturition diaries. Adverse events were also evaluated. Statistics were descriptive. Dose escalation of either trospium or oxybutynin increased reduction in UUI episodes in the population studied. At study end, there were no relevant differences between the "dose adjustment" subgroups and the respective "no dose adjustment" subgroups (trospium: P = 0.249; oxybutynin: P = 0.349). After dose escalation, worsening of dry mouth was higher in both dose adjusted subgroups compared to the respective "no dose adjustment" subgroups (P < 0.001). Worsening of dry mouth was lower in the trospium groups than in the oxybutynin groups (P < 0.001). Adverse events were increased in the dose adjusted subgroups. Flexible dosing of trospium was proven to be as effective, but better tolerated as the officially approved adjusted dose of oxybutynin. The study was registered with the German Federal Institute for Drugs and Medical Devices (BfArM, Berlin, Germany), registration number 4022383, as required at the time point of planning this study.
