ObjectivesTo 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 Methods56 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.ResultsAll 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.ConclusionsRecovery to spontaneous voiding after acute urinary retention in the hospital setting may be anticipated by evaluation of lower limbs function measured by validated instruments.
Aims: Involuntary Detrusor Contraction (IDC) may alter therapeutic plans; therefore, urodynamic demonstration (UD) is pivotal. We explore if same session repetitions enhance its demonstration and minimize false-negative results. Methods: Two hundred fifty two women (mean age 47 ± 5.7) had 4 full repetitions of UD with the last round filled with 4°C fluid (Ice-water test). IDC was diagnosed if with at least 3 cm H2O after artifacts were ruled out. Results: 44.4% of the cases showed IDC in the first round of the exam but it could be demonstrated in 88.5% of the women if 4 rounds are taken into account. Only 2 cases showed IDC exclusively in the first round. Nine cases (3.5%) showed IDC in the first round and only on Ice-test, while all other IDC-detected cases revealed it in scattered patterns along the repetitions. Likewise, IDC detection on the second, third and fourth rounds varied widely and unpredictably, many failing to show a consistent pattern of presentation after its detection. IDC wave amplitude did not show any correlation to the detection. Conclusions: Urodynamic repetition is a necessary procedure where IDC is important to demonstrate, as its false-negative rate is high and its unpredictable pattern of detection may be improved by repetition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
