One hundred cases of sui treatment that failed: a prospective observational study on the behavior of patients after surgical failure

Objectives Determine what happens to patients after unsuccessful SUI operations and to explore the reasons why these patients change doctors. Materials and Methods One hundred consecutive failed patients treated for SUI were interviewed about the exams requested after persistence of the incontinence as well as the reasons they abandoned their primary doctors through a structured questionnaire. Results Among the patients with cases of anterior colporrhaphy, bladder suspensions or slings, 34.3%, 13.7% and 8.3%, respectively, were not offered any further type of investigative procedures to clarify the failure. Urodynamic evaluations were recommended in 75% of failed slings, and 66.6% of the patients proceeded with these tests. In contrast, only 31% of patients with bladder suspensions and 40% of patients with anterior colporrhaphy were recommended for urodynamic investigations, and only 44.4% and 28.5% of them, respectively, proceeded with the option. Patients´ delusions were reinforced by the doctors’ attitude toward the investigations. Vacuous justifications and the lack of intention to seek improvement were the driving forces causing the patients to change doctors. Conclusion Unsuccessful patients are evaluated in a non-protocol form. Difficulty in clarifying the reasons for surgical failure and the disruption of the doctor-patient relationship are the main reasons why patients abandon them

Rate of spontaneous voiding recovery after acute urinary retention due to bed rest in the hospital setting in a non-urological population clinical study of the relationship between lower limbs and bladder function

Abstract Objectives To understand the clinical relationship between lower limbs functions and the recovery of spontaneous voiding after an acute urinary retention (AUR) in older patients admitted to hospitals for non-urological causes using clinical parameters. Materials and Methods 56 adult patients (32 men; mean age: 77.9 ± 8.3 and 24 women; mean age 82.1 ± 4.6) with AUR were prospectively followed with validated Physical Performance Mobility Exam (PPME) instrument to evaluate the relationship between the recovery of mobility capacity and spontaneous voiding. After a short period of permanent bladder drainage patients started CIC along evaluation by PPME during hospitalization and at 7, 15, 30 60, 90, and 180 days of discharge. Mann-Whitney U, chi-square test and ANOVA tests were used. Results All patients were hospitalized for at least 15 days (Median 26.3 ± 4.1 days). Progressive improvement on mobility scale measured by PPME was observed after leaving ICU and along the initial 7 days of hospitalization but with a deterioration if hospitalization extends beyond 15 days (p<0.03). Prolonged hospital stay impairs mobility in all domains (p<0.05) except step-up and transfer skills (p<0.02) although a recovery rate on spontaneous voiding persistented. Restoration of spontaneous voiding was accompanied by improvement on mobility scale (p<0.02). Recovery of spontaneous voiding was markedly observed after discharging the hospital. All patients recovered spontaneous voiding until 6 months of follow-up. Conclusions Recovery to spontaneous voiding after acute urinary retention in the hospital setting may be anticipated by evaluation of lower limbs function measured by validated instruments

A randomized and prospective study on the value of antibiotic prophylaxis administration in transurethral resection of the prostate

CONTEXT: Antibiotic prophylaxis in transurethral resection of the prostate is a regular practice in urology. However, its prophylactic effect can be questioned when the antiseptic surgical technique is used. Nonetheless, urine culture-oriented antibiotic therapy is the gold standard for avoiding improper medication usage and bacterial resistance. OBJECTIVE: To study the efficacy of antibiotic usage in patients with negative urine cultures, who were submitted to transurethral resection of the prostate. TYPE OF STUDY: Prospective open labeled study. SETTING: Tertiary care referral hospital PARTICIPANTS: 124 consecutive patients, who were randomly divided into two groups to receive antibiotic prophylaxis or not. MAIN MEASUREMENTS: Cultures from meatus, urine, irrigation and antiseptic fluid, and prostate tissue chips, were compared and analyzed for bacterial sensitivity to the antibiotic used, according to the surgeon's personal criteria. McLennan's test was used for statistical analysis. RESULTS: No statistically significant difference regarding clinical evolution was found between the groups that received or antibiotics or not. Statistical significance was found regarding the occurrence of positive urine cultures during the postoperative period for those not receiving antibiotics, but not in relation to fever, prostate chip culture or bacteremic episodes. Sixty-eight subjects (57.1%) presented positive prostatic tissue culture. There was no specific correlation between the recovered bacteria from the meatus, prostatic tissue chip and urine and the spectrum of the administered antibiotic. Six cases showed the same bacteria in the urine and prostatic tissue chip. Only fifteen cases (25%) in the antibiotic group showed the desired sensitivity directed to the collected bacteria. CONCLUSIONS: Antibiotic prophylaxis for patients whose urine is sterile is debatable in patients who are candidates for transurethral resection of the prostate. Most of the time, the antibiotic agent used is not specific for any of the bacteria recovered from the various sources analyzed

Lymphocele: a possible relationship with acute cellular rejection in kidney transplantation

CONTEXT: The incidence of lymphocele after renal transplantation varies between 0.6 and 18% of cases, and many factors have been associated to its etiology. Cellular rejection of the kidney allograft has been described as a possible causal factor of lymphocele. OBJECTIVE: To analyze the possible relationship between lymphocele and acute cellular rejection. DESIGN: A retrospective study. SETTING: A referral hospital center. SAMPLE: 170 patients submitted to kidney transplantation from March 1992 to January 1997. A standard technique for renal transplantation was used. RESULTS: Of the 19 patients that developed lymphocele, 16 presented at least one episode of acute cell rejection (84%), and were treated with methylprednisolone. The relation between lymphocele and rejection was statistically significant (p = 0.04). Treatment of lymphocele consisted of peritoneal marsupialization in 3 patients (15.3%), percutaneous drainage in 7 (36.8%), laparascopic marsupialization in 2 (10.5%), and conservative treatment in 7 patients (36.8%). Evolution was favorable in 15 patients (78.9%), 1 patient (5.3%) died due to a cause unrelated to lymphocele, and 3 (15.8%) lost the graft due to immunological factors. The average follow-up period was 24.5 months. CONCLUSION: The high incidence of acute cell rejection in patients with lymphocele suggests a possible causal relationship between both conditions

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2

The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. Alignment scenarios are also derived for use in the simulation of the detector response. Systematic effects, related to intrinsic symmetries of the alignment task or to external constraints, are discussed and illustrated for different scenarios
