Complete intraureteral stent placement relieves daytime urinary frequency compared with conventional placement in patients with an indwelling ureteral stent: post-hoc analysis of a randomized, controlled trial.

ABSTRACT: A previous randomized, controlled trial had demonstrated that complete intraureteral stent placement (CIU-SP) was superior to conventional stent placement (C-SP) in terms of improvement of stent-related urinary symptoms. However, it is unclear as to which subdomain symptom and cohort could benefit the most from CIU-SP compared to C-SP in urinary symptoms while considering the baseline urinary status. To determine this, a post-hoc analysis was performed using data from a previous study (CIU-SP group, n?=?39; C-SP group, n?=?41). We assessed the mean changes in the International Prostate Symptom Score (I-PSS) and the Overactive Bladder Symptom Score (OABSS) from baseline to day 14. Statistical comparison between the two groups was performed using analysis of covariance with adjustment of baseline urinary status as a covariate. Among 80 patients, the total I-PSS was significantly lower in the CIU-SP group than in the C-SP group in the cohort with mild urinary symptoms (P?=?0.005), but not in those with moderate/severe symptoms (P?=?0.521). The CIU-SP group showed significantly improved I-PSS and OABSS daytime frequencies, with the highest t statistic (2.47 and 2.10, respectively) among subdomains of both symptom scores compared with the C-SP group (both P?

Project description:IntroductionWe aimed to assess the effects of postoperative ureteral stent placement after uncomplicated ureteroscopy.MethodsWe 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.ResultsWe included 23 studies with 2656 randomized patients. Primary outcomes: It is uncertain whether stenting reduces the number of unplanned return visits (very low certainty of evidence [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 (standardized mean 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 (risk ratio [RR] 1.15; 95% CI 0.39-3.33; low CoE).Secondary outcomesWe 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.ConclusionsFindings 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.

Project description:BackgroundMost patients suffer from ureteral stent-related symptoms (USRS) caused by indwelling ureteral stents. Nevertheless, various medications to alleviate discomfort as well as novel stents are continually being developed, and in recent years, some researchers have believed that proper intravesical stent placement can relieve USRS.ObjectiveTo determine appropriate intravesical ureteral stent position may alleviate USRS.MethodsUp to May 1, 2022, the PubMed, Embase, Scopus and Web of Science databases were thoroughly searched, and two independent reviewers included relevant studies that met the PICO (Patient, Intervention, Comparison, Outcome) criteria. Studies methodological quality were assessed by ROB2 and ROBINS-I. Ureteral stent symptom questionnaire (USSQ), international prostate symptom score (IPSS) and quality of life (QoL) was used to quantify the USRS. According to intravesical ureteral stent position, Group A was defined as the contralateral group, that is distal end of ureteral stent crossed the bladder midline, whereas Group B was classified as ipsilateral group, meaning stent end did not cross the midline.ResultsSix studies incorporating a total of 590 patients were eligible. In terms of USSQ score, the meta-analysis showed that contralateral group was associated with a significant increase in USSQ total (MD, 17.55; 95% CI, 12.04 to 23.07; P < 0.001), urinary symptoms (MD, 2.74; 95% CI, 0.48 to 5.01; P = 0.02), general health (MD, 4.04; 95% CI, 2.66 to 5.42; P < 0.001), work performance (MD, 1.36; 95% CI, 0.75 to 1.98; P < 0.001) and additional problems (MD, 0.89; 95% CI, 0.47 to 1.32; P < 0.001) scores while not associated with a significant increase in body pain (MD, 3.13; 95% CI, -0.19 to 6.44; P = 0.06) and sexual matters (MD, 1.01; 95% CI, -0.03 to 2.06; P = 0.06). As for IPSS, although no significant differences in IPSS total (MD, 2.65; 95% CI, -0.24 to 5.54; P = 0.07) or voiding symptoms (MD, -0.84; 95% CI, -3.16 to 1.48; P = 0.48) scores were found, ipsilateral group was associated with a significant decrease in storage symptoms (MD, 1.92; 95% CI, 0.91 to 2.93; P = 0.0002). Furthermore, ipsilateral group was linked to a significant decrease in QoL score (MD, 1.00; 95% CI, 0.18 to 1.82; P = 0.02).ConclusionThis meta-analysis proven that correct intravesical stent position was critical, and patients with stents crossing the midline experienced more severe USRS than those who did not. Further high-quality randomized controlled trials are needed to corroborate our findings.
