57159.pdf (publisher's version ) (Closed access)HYPOTHESIS: Surgeons' preferences for any of 3 methods of inguinal hernia repair are comparable in terms of operating time, incision length, perceived difficulty, and surgeon's satisfaction. DESIGN: Randomized patient-blinded study. SETTING: Teaching hospital. PATIENTS: A total of 334 patients randomized to receive 1 of the 3 repairs. INTERVENTIONS: Patients underwent hernia repair with the Prolene Hernia System, mesh plug repair, or Lichtenstein technique. MAIN OUTCOME MEASURES: Operating variables, surgeon's rating of satisfaction and difficulty, grade and experience of the operating team, and complications. RESULTS: The Lichtenstein technique took significantly the longest operating time (52 minutes vs 41 or 42 minutes; P<.001). The mesh plug repair scored the best results in difficulty and satisfaction. Overall, surgeons having performed more than 5 procedures rated the repairs less difficult and with significantly more satisfaction (P<.001 and P = .001, respectively). The complication rate did not differ between the treatment groups. None of the operative findings was correlated to the outcome, except for adverse correlation with the body mass index. CONCLUSION: From a surgeon's point of view, the mesh plug repair is superior to the Lichtenstein technique and the Prolene Hernia System in terms of operating time, incision length, perceived difficulty, and surgeon's satisfaction

Treatment response of an outpatient training for children with enuresis in a tertiary health care setting
Item does not contain fulltextPURPOSE: To evaluate treatment effectiveness for children with enuresis, according to the definitions of the International Children's Continence Society (ICCS, 2006). MATERIAL AND METHODS: Children >/=6 years of age followed a 4-month outpatient treatment consisted of a visit during which history regarding enuresis was taken, causes were explained and therapeutic tips & tricks were discussed. All children received a booklet about enuresis and were trained with an alarm and/or pharmacological therapy. At baseline, 4, 10 and 16 months, the number of wet nights during the previous 28 days and the use of medication were assessed. Success of treatment was determined using ICCS definitions of treatment outcome. RESULTS: 66 children with enuresis were included (48 boys/18 girls) in this retrospective study. Mean age: 11(+/-2.6) years. 91%(n = 60) of the children had non-monosymptomatic enuresis. Results at 4 months: 46% full, 15% good, 21% partial response (n = 66). At 10 months: 55% full, 4% good, 29% partial response (n = 49). At 16 months: 53% full, 6% good, 25% partial response (n = 34). Overall, use of pharmacological therapy showed a decline in time. CONCLUSION: According to the ICCS definitions, outpatient treatment for enuresis shows a good overall treatment response, and these results can be used to compare with other studies in the future
Clinical protocol levels are required in laboratory animal surgery when using medical devices: experiences with ureteral replacement surgery in goats

178252.pdf (publisher's version ) (Open Access)It is common to test medical devices in large animal studies that are or could also be used in humans. In this short report we describe the use of a ureteral J-stent for the evaluation of biodegradable tubular constructs for tissue reconstruction, and the regeneration of ureters in Saanen goats. Similarly to a previous study in pigs, the ureteral J-stent was blindly inserted until some resistance was met. During evaluation of the goats after three months, perforation of the renal cortex by the stent was observed in four out of seven animals. These results indicated that blind stent placement was not possible in goats. In four new goats, clinical protocols were followed using X-ray and iodinated contrast fluids to visualize the kidney and stent during stent placement. With this adaptation the stents were successfully placed in the kidneys of these four new goats with minimal additional effort. It is likely that other groups in other fields ran into similar problems that could have been avoided by following clinical protocols. Therefore, we would like to stress the importance of following clinical protocols when using medical devices in animals to prevent unnecessary suffering and to reduce the number of animals needed

Urotherapy in children: quantitative measurements of daytime urinary incontinence before and after treatment according to the new definitions of the International Children's Continence Society
OBJECTIVE: To assess the effectiveness of urotherapy in children with lower urinary tract dysfunction, according to the new definitions of the International Children's Continence Society. MATERIAL AND METHODS: We performed a retrospective review of 122 children (aged 8.8 +/- 2.0 years) treated in an outpatient program for lower urinary tract dysfunction. Exclusion criteria included all neurologic abnormalities. In 98 children (80%) daytime urinary incontinence was a predominant symptom. Therapy consisted of an individually adapted drinking and voiding schedule, pelvic floor relaxation, instructions on toilet behavior, biofeedback uroflowmetry and if necessary recommendations for regulation of defecation. Before and at the end of training, patients were evaluated for number and severity of daytime wet accidents per week, using a scoring system to grade the severity of incontinence. Secondary measurements of accompanying voiding symptoms were performed. RESULTS: Of the 90 children with daytime urinary incontinence for whom sufficient objective data were collected, 42% became completely dry during the daytime and 36% showed a 50% or greater level of response. Secondary measurements showed a significant reduction in daily voiding frequency (mean 7.0 +/- .3, P<0.0001) and mean post-void residual (P<0.003), and an improvement in flow pattern (P<0.05). CONCLUSIONS: Urotherapy is successful for the treatment of daytime urinary incontinence in children. Additional benefit was evident in improvement of accompanying voiding symptoms. A combination of the definitions of the International Children's Continence Society and a scoring system to grade severity improved the evaluation method. Further research into long-term efficacy will be performed
Tolerability of 3.5 versus 2.5 high-energy transurethral microwave thermotherapy
To evaluate the tolerability of high-energy microwave thermotherapy in patients with benign prostatic hyperplasia (BPH) using two different treatment protocols (Prostasoft 2.5 and Prostasoft 3.5). Pain and discomfort during treatment was evaluated using a visual analog scale in 39 patients undergoing 60-min Prostasoft 2.5 treatment and 41 patients undergoing 30-min Prostasoft 3.5 treatment. The duration of transurethral microwave thermotherapy (TUMT) 3.5 treatment is significantly shorter than TUMT 2.5 treatment. The pain level is significantly higher at the beginning of the Prostasoft 3.5 treatment compared to the Prostasoft 2.5 treatment. The reported pain level becomes similar 10 min into treatment, and remains similar to the end of the 3.5 treatment (at 30 min), when the pain level returns to baseline. The 2.5 protocol patients experience continuously increasing pain until the end of the treatment at 60 min. One minute following termination of treatment, the pain level drops back to the baseline level. No correlation between the level of pain and the baseline subjective or objective voiding parameters was observed. A correlation is also absent between the pain level, age and catheterization time. There only seems to be a weak correlation between the pain level and TUMT energy in the Prostasoft 2.5 treatment group. Both TUMT 2.5 and TUMT 3.5 are well tolerated. Even though patients undergoing TUMT 3.5 treatment experience more discomfort initially, the ultimate discomfort is similar to the TUMT 2.5 treatment, during the first 30 min. Shortening of treatment time significantly reduces the pain and discomfort experienced by the patient. Pretreatment parameters are not predictors of the pain level experience
