Introduction: We aimed to assess the effects of postoperative ureteral stent placement after uncomplicated ureteroscopy. Methods: We performed a comprehensive search with no restrictions on publication language or status up to February 1, 2019. We only included randomized trials. Two review authors independently examined full-text reports, identified relevant studies, assessed the eligibility of studies for inclusion, extracted data, and assessed risk of bias. We performed statistical analyses using a random-effects model and assessed the certainty of the evidence according to GRADE. Results: We included 23 studies with 2656 randomized patients. Primary outcomes: It is uncertain whether stenting reduces the number of unplanned return visits (very low CoE). Pain on the day of surgery is probably similar (mean difference [MD] 0.32; 95% confidence interval (CI) -0.13‒0.78; moderate CoE). Pain on postoperative days 1‒3 may show little to no difference (SMD 0.25; 95% CI -0.32‒0.82; low CoE). It is uncertain whether stented patients experience more pain on postoperative days 4‒30 (very low CoE). Stenting may result in little to no difference in the need for secondary interventions (relative risk [RR] 1.15; 95% CI 0.39‒3.33; low CoE). Secondary outcomes: We are uncertain whether stenting reduces the need for narcotics and reduces ureteral stricture rates up to 90 days (very low CoE). Rates of hospital admission may be slightly reduced (RR 0.70; 95% CI 0.32‒1.55; low CoE). This review was limited to patients in whom ureteroscopy was deemed ‘uncomplicated.’ In addition, time intervals for the grouping for the reported degree of pain were established post hoc. The CoE for most outcomes was rated as low or very low for methodological reasons. Conclusions: Findings of this review illustrate the tradeoffs of risks and benefits faced by urologists and their patients when it comes to decision-making about stent placement after uncomplicated ureteroscopy for stone disease.

Background When antegrade ureteral intervention fails due to severe ureteral stricture or tortuosity, a longer sheath can be used to facilitate ureteral catheterization. Purpose To evaluate the feasibility and effectiveness of the use of a long sheath in antegrade ureteral stent placement after failure of antegrade ureteral stent placement using a short sheath. Material and Methods Among 1284 procedures in 934 patients who received ureteral stent placement, a long sheath was used after stricture negotiation failure using a short sheath in 57 (4.4%) procedures in 53 patients. The data of these 53 patients were retrospectively reviewed. Results The most common reasons for long sheath use were failure of balloon catheter (59.6%) or guidewire (29.8%) advancement across the stricture. Technical success, successful stricture negotiation after using a long sheath, was achieved in 50/57 (87.7%) procedures. In two of seven failed procedures, an additional TIPS sheath was used and the technical success rate improved to 91.2% (52/57). The technical success rate was significantly higher in the patients who have failed balloon catheter advancement (97.1%, 33/34) than the patients who have failed guidewire advancement (64.7%, 11/17) (Fisher’s exact test, P = 0.004). Self-limiting hematoma occurred in one patient after use of the long sheath and was considered a minor complication. Conclusion Ureteral catheterization using a long sheath is feasible and effective when antegrade ureteral intervention using a short sheath fails. When using a long sheath, the technical success rate was higher when advancing the balloon catheter over the guidewire than when advancing the guidewire through tight stricture.

Sleep Positioning

Introduction Sleep positioning systems are often prescribed as part of a 24-hour postural management programme for children and adults with neurodisabilities. In a search for evidence of effectiveness for children with cerebral palsy a recent Cochrane review found two randomised controlled trials. This review aims to appraise a broader set of studies including any neurological diagnosis and users of all ages to inform therapists about the quality of the evidence underlying practice. Method A comprehensive search for all peer-reviewed studies that evaluated the use of sleep positioning systems was conducted in MEDLINE, EMBASE, CINAHL, Cochrane Library databases, BNI, HMIC, PEDro, OTSeeker and clinical trials registries. Disability organisations, manufacturers and colleagues worldwide were also contacted. Titles were screened for relevance by two reviewers. Data were extracted into bespoke quantitative or qualitative forms by one reviewer and checked by a second. Findings were analysed into simple themes. Results A total of 14 studies were eligible for inclusion; all were small and most were of low quality. Inferences of benefits cannot be made from the literature but also no harm was found. Conclusions The body of evidence supporting practice remains small and mostly of low quality. Therapists should remain cautious when presenting the benefits to families.

Interoceptive awareness is linked to emotional and social cognition, which are impaired in individuals with autism spectrum disorder (ASD). It is unknown how this ability is associated with age in either typical or atypical development. We used a standard test of interoceptive accuracy (IA) to investigate these questions in children and adults with and without ASD. Perceived number of heartbeats over 4 time intervals was compared with actual heart rate to determine IA. Effects of group, age, IQ, heart rate, and mental counting ability on accuracy were assessed using multiple regression. Post hoc correlations were performed to clarify significant interactions. Age was unrelated to IA in both groups when IQ ≥115. When IQ <115, this relationship was positive in typical development and negative in ASD. These results suggest that cognitive ability moderates the effect of age on IA differently in autism and typical development.
